One of my favorite applications (Anki) now required glibc 2.36 or later for the application to run. Is it possible to upgrade to this version of glibc on PopOS? Is there a more up-to-date APA for the package?

I'm using an ASUS ZenBook 14 (UX3405CA) with an Intel WiFi 7 card. A couple weeks ago, I was running Arch and bluetoothctl worked, but graphical controls like blueman would show that bluetooth was disabled. Recently, I migrated to the PopOS 24.04 alpha since I wanted to test out COSMIC and also have a bit more stable OS. Now, regardless of whether I use COSMIC or a stable session like Gnome, bluetooth is completely borked. GUI bluetooth managers are actually worse now (blueman crashes when I try to enable Bluetooth), and bluetoothctl doesn't work anymore. bluetoothctl list yields no output. lsusb does not list any Bluetooth adapters. inxi -bE:

Recently, I changed my default file manager from Nautilus to Dolphin in Pop!_OS by this command:

xdg-mime default org.kde.dolphin.desktop inode/directory'

and checked again which is the default file manager by executing this command:

xdg-mime query default inode/directory

and I get this output:

org.kde.dolphin.desktop

But, Gogle Chrome still opens Nautilus as the default file manager. I thought of removing it, but doing so will result in potential damage to my system since it is a built-in file. Here is the picture to view the scenario. And, instantly when I browsed that picture, Chrome, as usual, used Nautilus to browse the picture. Anyway to sort out this issue? I just want to sure that all applications use Dolphin as the default file manager without removing Nautilus. Update: As suggested, I also used xdg-open command to find the default file manager the system is using. And I noticed that, Dolphin opens up automatically with the entered file location.

I'm brand new to Linux, and I have installed Pop! OS to replace my Windows installation. Enjoying it so far, but having some troubles with high-res monitor scaling. My first monitor is 3440x1440 (21:9 ultrawide) resolution, and my other monitor is 3840:2160(4k). I want to have the ultrawide monitor be scaled to 100%, but I want the 4k monitor to be scaled to somewhere around 150%-200%. I noticed that in the display settings, I can turn on the fractional scaling, and set scaling separately that way, but when I do so, there is some weird behavior. I noticed that in games, I could set my resolution to 6880x2880. So after messing around, it seems like if I do the fractional scaling, it increases the size of my main monitor, which I do not want to happen, because then gaming is much more difficult performance-wise. So, I want a way that I can have separate scaling between the two that doesn't involve fractional scaling. More over, I tried to use an xrandr command that I found online, and it basically completely broke everything, and made both of my screens act crazy, and I had to reboot. So I'm not super sure that will work either. Any suggestions?

I want to change from Windows to Pop OS, I don't want to make a partition and getting a dual boot, just want to say goodbye to Windows, the issue is that I'm not pretty sure if doing this having two Hard-disks (128GB+1TB), so, is it possible that I loose one Hard-disk on the process ? I'm worried to loose the 1TB Hard-disk (currently I'm working on my local C drive (the one of 128GB, so don't know if I can loose the 1TB of storage).

So I've encountered this problem every time I installed linux on my laptop. I've asked it before here , but that didn't go well. Now I'v installed Pop OS (22.04) and I'm fully committed to it, it's not dual boot anymore and it's the only OS I currently run. I did try gaming on it and works just fine, I actually have no problem right now with it, except the brightness of course xd The situation: Brightness of the screen is stuck at maximum (I think, it's really bright), the actual_brightness file has 100 in it, the brightness slider changes the brightness file (both files on /sys/class/backlight/nvidia_0).
I CAN change the brightness using xrandr --output DP-2 --brightness 0.5 for example, but it won't stay that way and none of the files I mentioned change when I use xrandr.
Also, the keyboard backlight works just fine, I didn't install any RGB related software and it has the default red color but the brightness level is working perfect. Changing the brightness of the keyboard backlight will return the display brightness to maximum, if I've used xrandr before and changed it. What I have done: I did dual boot Pop OS before wiping windows from the laptop, and in dual boot mode, I've changed the permissions of brightness and actual_brightness files (chmod 777), and also tried to manually write numbers in them but it didn't work (Used nano and vim for it, in sudo mode). I've searched for solutions but couldn't find working ones. There were somethings about older versions of nvidia drivers solving these problems, but: 1. I need up to date drivers, because I game on it and can't keep an outdated driver for gaming. Basically everything I need to install (steam, wine, lutris) will update the drivers or need up to date drivers. 2. This problem is not new, I had it every single time I've installed linux on this laptop (multiple times Ubuntu, I think I did manjaro one time and probably Pop OS before), and I think it's something related to how my hardware interacts with linux or something. My specs: ASUS ROG GL503VS, Intel Corei7-7700HQ, Nvidia Geforce GTX 1070 (The only GPU on my laptop, and it is dedicated of course), 1920x1080 144hz GeSync capable display (I don't know if it helps at all).

If any other information is needed, I can happily give it to you. I'm quite new to linux (despite many tries) and know a thing or two but not much at all. I really want to use it as my main OS, but I think I'm gonna lose my eyes in the process if I can't solve this problem XD. Many thanks in advance.

Currently running Pop!_OS 22.04 LTS X64 I'm extremely new to linux as a whole so I'm sorry if this is a stupid question. I'm attempting to set up virtual audio cables for recording and I've managed to find that using pulseaudio I can have them, but it will not persist through a reboot. I was told to make a file called default.pa in ~/.config/pulse directory and what I have in there at the moment is

.include /etc/pulse/default.pa
.ifexists module-virtual-sink.so
load-module module-virtual-sink sink_name=VAC_1
load-module module-virtual-sink sink_name=VAC_2
load-module module-virtual-sink sink_name=VAC_3

but it was not working after a reboot and even attempting to format it the same as the command I run in Terminal to make them. The command I am running to make the audio channels normally is

pactl load-module module-virtual-sink sink_name=VAC_1

I'm sure I am doing something wrong but, as I am inexperienced, I am lost.

_OS community, I’m experiencing persistent USB issues on my Acer Aspire 3 running Pop!_OS 22.04, and I’d appreciate some guidance. The problem involves frequent USB controller failures and device disconnections, which don’t occur when I use the same peripherals on Windows 11. I’ve tried multiple troubleshooting steps, including updating the kernel, disabling the touchpad, and using a new mouse with a lower polling rate, but the issue persists. **Background** Hardware: Acer Aspire 3 notebook. OS: Pop!_OS 22.04 (based on Ubuntu 22.04). Peripherals: Previously used a Corsair Harpoon RGB PRO (1000Hz polling) and now a YSPRINGTECH USB OPTICAL MOUSE (lower polling rate), plus an internal ELAN050A touchpad. Observation: On Windows 11 (dual-boot), there are no USB problems with the same setup, suggesting a Linux-specific driver or configuration issue. **Symptoms** USB devices disconnect or require resets. The xHCI controller reports errors, especially during resume from suspend. Additional issues with power management, Acer WMI, and SATA links are present, which might be related. **Troubleshooting Attempted** Updated the kernel to the latest HWE version (e.g., 5.15.0-107). Disabled the touchpad (ID 17) using xinput disable 17 to rule out its interference. Switched to a mouse with a lower polling rate (10000us 4 times, consider switching to WQ_UNBOUND [Jun 28 12:35:03] workqueue: power_supply_changed_work hogged CPU for >10000us 5 times, consider switching to WQ_UNBOUND [Jun 29 20:39:47] workqueue: power_supply_changed_work hogged CPU for >10000us 4 times, consider switching to WQ_UNBOUND [Jun 29 20:39:56] workqueue: power_supply_changed_work hogged CPU for >10000us 5 times, consider switching to WQ_UNBOUND [Jun 29 20:40:04] workqueue: power_supply_changed_work hogged CPU for >10000us 7 times, consider switching to WQ_UNBOUND [Jun 29 20:40:54] workqueue: power_supply_changed_work hogged CPU for >10000us 11 times, consider switching to WQ_UNBOUND [Jun 28 12:28:18] acer_wmi: Unknown function number - 8 - 0 [Jun 28 12:38:51] acer_wmi: Unknown function number - 8 - 0 [Jun 28 12:38:56] acer_wmi: Unknown function number - 8 - 1 [Jun 29 20:32:37] acer_wmi: Unknown function number - 8 - 0 [Jun 29 20:39:32] acer_wmi: Unknown function number - 8 - 0 [Jun 29 20:39:34] acer_wmi: Unknown function number - 8 - 1 [Jun 29 20:41:03] acer_wmi: Unknown function number - 8 - 0 [Jun 29 20:41:08] acer_wmi: Unknown function number - 8 - 1 [Jun 28 12:38:57] ata1: SATA link down (SStatus 0 SControl 300) [Jun 29 20:39:09] ata1: SATA link down (SStatus 0 SControl 300) [Jun 29 20:41:09] ata1: SATA link down (SStatus 0 SControl 300) [2247.818144] ACPI BIOS Error [13.652880] TSC found unstable ``` I’d love to get advice from the community on how to stabilize the USB subsystem. Could this be a driver issue, a BIOS incompatibility, or a power management problem? Any suggestions on further diagnostics or fixes would be greatly appreciated. I’m hesitant to update the BIOS without confirmation, given the risks. Thanks in advance for your support!

I'm using Pop! OS. When running any simple

or

-get

command in the terminal, even something as simple as

--help

, I get an error message

apt: /lib/x86_64-linux-gnu/libc.so.6: version 'GLIBC_2.32' not found (required by /lib/x86_64-linux-gnu/libsystemd.so.0)

However, when I enter

--version

it tells me tat I am using GLIBC 2.32. - specifically, it says

lld (Ubuntu GLIBC 2.32-0ubuntu3) 2.32

Every fix I've found online has suggested using something like

apt clean

to clean, update or otherwise fix things, but the Catch-22 here is that

is precisely what I can't use. Is there some sort of manual fix I can do? This issue is making my computer basically unusable, so any help would be greatly appreciated.

Unfortunately, for some but not all programs (Thunderbird, Signal, Libre Office, QGIS) the minimize and maximize were suddenly missing and appear maximized (not full screen. I noticed it suddenly without having installed anything previously). All other programs appear with minimize and maximize buttons. Since, I have updated my Pop! OS (to Pop!_OS 22.04 LTS) and tried reinstalling the programs as well as changing the settings in GNOME 3, but without any success. Especially for QGIS without the buttons I cannot move the different window of the program and thus can hardly use it.

I have windows 11 on 250gb ssd and a 500gb empty hard drive. I want to install POP!os on one of the partition of this Hard drive and let the windows be on the ssd. So while partitioning space to install linux if I select D drive from my HardDisk and does further partitioning there for linux os then we will get Erase and install option. **Now does this option erase all my data from the ssd also? or only from the drive I selected.** If it does delete then what is the other safer option to not delete the ssd data? Also is this way of partitioning correct or Am I doing anything wrong?

## Scenario Have an external device, encrypted with LUKS, automatically mount when inserted and not cause any issues if not present on boot. > Most questions on this topic refer to mounting on boot - this is NOT what I am trying to do Additionally, the mountpoint should be protected from accidental writes when the usb device is not present and I can do this with chattr +i ## Problem 1. When the external device is NOT mounted, any attempt to access the mountpoint will hang until timeout - this can cause system instability. 1. When the device is inserted, the passphrase is prompted for and device unlocked, but not mounted. I then have to mount the device manually with mount /mnt/backup or mount /dev/mapper/fit which appears to correctly use the fstab settings. ## Configuration

# /etc/crypttab
fit   UUID=xxxxxxxx-xxxxx-xxxxxxxx-xxxxxxxxxx none luks,noauto

# /etc/fstab

andy@pop-os:mnt$ umount /mnt/backup

andy@pop-os:mnt$ sudo cryptsetup close fit

andy@pop-os:mnt$ sudo eject /dev/sdx

### Temporary Resolution I can unmount the mountpoint (even though no device is mounted anyway) to temporarly fix this issue but it will come back after a system reboot or after mounting/ummounting the device again.

andy@pop-os:mnt$ sudo umount backup

andy@pop-os:mnt$ ll

/mnt/backup is not a mountpoint

If I use noauto and don't include x-systemd.automount then I avoid the problem of the directory being a mountpoint on boot when no device is present, but I also don't get automounting - although the device still unlocks. ## Mounting the external device Passphrase is prompted for and device unlocked

... but usually this just mounts the device as expected. ## Other Issues - If I do not set [x-systemd.device-timeout](https://www.freedesktop.org/software/systemd/man/systemd.mount.html#x-systemd.automount) to something much less than the default 90s then my system will slowly become unresponsive and then crash. I thought systemd might be timing out waiting for me to type in my passphrase but longer timeouts didn't seem to help - I copied the configuration from an old Ubuntu 22.04 system to Pop!_OS 22.04, I would sometimes see the question marks while listing the directory in the unmounted state but the auto-mount worked perfectly. On the old system I didn't set the immutable attribute on the mountpoint. ## Related - [mount-error-when-automounting-a-luks-encrypted-usb-flashdrive](https://unix.stackexchange.com/questions/281349/mount-error-when-automounting-a-luks-encrypted-usb-flashdrive) - different errors and method of mounting - [Automounting USB sticks on Debian](https://unix.stackexchange.com/a/346830/458741) - uses a slightly different method with nofail instead of noauto but unfortunately doesn't answer my question - I can get more information with systemctl show mnt-backup.mount but this hasn't helped me - The man page for [fstab](https://wiki.archlinux.org/title/fstab) says what to do for external devices but these settings don't auto mount the device and do cause the boot process to hang --- So, why does accessing the mountpoint try to access the device after it has been unmounted resulting in ?????????, and why does it not automount correctly when the device is inserted? Between the old fstab and new systemd I can't seem to find the magic variables. Would also be useful to know why the system crashes if I don't set the device timeout? --- ### Update August 2023 [mount-vs-automount-systemd-units...](https://unix.stackexchange.com/questions/570958/mount-vs-automount-systemd-units-which-one-to-use-for-what) explains the ????? as the .automount unit attempts to open the mountpoint on access. I have still been unable to achieve the behaviour I want though, and wonder if it because without configuring anything udev is used and then the only problem is being able to customise the directory used as a mountpoint. As soon as an fstab entry is made, /run/systemd/generator systemd units are made and the behaviour changes. There also seems to be a problem on my new system with plymouth as this spits out errors while systemd uses 100% CPU and hangs the system. This doesn't happen on my old laptop.

I'm having trouble getting WiFi working on **Pop!_OS 22.04** with a **Realtek RTL8822CE** card. It worked fine until recently but now: - WiFi randomly disconnects - Sometimes the WiFi option disappears from settings - lshw shows it as **UNCLAIMED** --- ### Here is my system info - **OS**: Pop!_OS 22.04 - **Kernel**: 6.12.10-76061203-generic - **Wi-Fi Card**: Realtek RTL8822CE (03:00.0)

If anyone has ideas (different drivers, kernel headers, workarounds, etc.), I’d really appreciate the help. Happy to provide more logs if needed.

I am using Pop!_OS, installed it a few days ago. I have two audio output devices (correction: read #1 under the post) connected to my PC, one to the 3.5mm audio jack in the front panel and one to the same in the back panel. In the front panel I have my headphones connected and in the back panel I have my stereo speakers connected. I want to be able to switch between the two devices (correction: read #1) like I do on Windows. But I am not able to achieve the same on Linux. (I do not want to be able to play audio from both the devices at once, I don't care about that. I want to be able to switch the output devices with audio playing from only one of them) works kinda like a phone, if I pull my headphones out it automatically starts playing audio from the speakers but as soon as I plug them back in, the audio switches to headphones. Basically my PC is not recognizing headphones and speakers as two separate output devices. Even in settings, only the headphones are available in the list of output devices and line in only appears if I pull my headphones out. Then it starts showing "line in". It works absolutely fine on Windows tho. Note: Don't freak out after seeing Pop!_OS mentioned it's very similar to stock Ubuntu just with better and more functional features. # 1: Someone told me that what I wanna do is not to switch between different audio output devices but rather different audio sinks or jacks connected to the same audio output device. Meaning, my headphone and speakers are not the audio devices, my sound card is which has two different sinks or jacks that my speakers and headphones are connected to. So I don't want to swtich output devicrs, I want to switch audio sinks or jacks.

I basically can't use apt without running into an error since this morning as all calls will result in the error: kernelstub.Installer : ERROR Couldn't copy the initrd onto the ESP!.

Any ideas how to fix this?

I'm running Pop!_OS 22.04 LTS with the GNOME version 42.5 on a X11 Framework Laptop. In the Extensions Manager (Version 0.4.0) I can browse extensions and click on install but they won't install and will provide no feedback. On extensions.gnome.org I can click on the on switch, it will prompt me to install the package but it won't really install it. On the website I see a banner telling me "Your native host connector do not support following APIs: v6. Probably you should upgrade native host connector or install plugins for missing APIs. Refer documentation for instructions.". I have actually installed the gnome-shell-extension-manager@0.3.0-0ubuntu2.1, gnome-shell-extensions@42.1-0ubuntu1, chrome-gnome-shell@10.1-5 but it still doesn't install the extensions. I am kind of stuck. Any idea what could solve this? Any help is appreciated! Thx!

I'm struggling to synchronize my system clock on Pop OS 21.04. I've read a lot of posts on the subject but it doesn't seem to help. my system clock are not synchronized, which caused issues with loading some resources (e.g. gitlab)

$ timedatectl

any help on how to synchronize system clock?

So I have win 11 and pop os dual installed on the same drive. I switched between them from boot menu, but suddenly I couldn't find pop os in the menu, probably because of my corrupted USB flasg drive I removed without ejecting while it was getting scanned by a badblocks command. I tried to access my pop os partition from windows through a program, and my files were there but the /boot/efi folder was empty.So I'm trying to add a new bootloader in the ESP That was already there by trying to install new pop os, but without erasing my root partition. But I'm afraid to continue sinvlce the option says erase and install. Do you think I should continue?

I'm using: Pop!_OS 24.04 LTS x86_64; DE: COSMIC I wanted to change my shortcut for opening launcher to Alt+Space: Each time I do that it erases and don't allow me to switch to this given combination with Space. For instance I was changing other shortcuts without any problems; yet I could also switch that shortcut but I wasn't allow for any combination including Space. Is it known issue that you cannot use Space for shortcut or is there any workaround?

All of a sudden, my laptop decided to detect headphones when no headphones are connected. I have tried using pavucontrol which shows speakers (unavailable). Even though moving the volume makes the sound come out of the built-in speakers (suggesting that the speakers do work!,right?) Though the headphones still remain mistakenly connected. I also tried using hdajackretask as suggested in the post here though it seemed confusing and I am not sure how to read the output from

/proc/asound/card*/codec\#*

But this is what I got https://pastebin.com/Z117DbR6 However doing grep -i jack gives me

I think it says HDMI, because I use the thunderbolt jack in my laptop to connect to my monitor. (Though I am not sure, because the port it connects to in the monitor is a DisplayPort specifically) Any help would be greatly appreciated. I am new to linux, minor troubleshoots are fine for me, however this time I am not sure if this is even a hardware issue or not.
