My notebook, an older Apple MacBookAir 13" with Intel Core i7 an Intel HD Graphics 5000, used to work fine before the upgrade to Trixie (Debian GNU/Linux 13). Now, after the upgrade, all rendering is done using the CPU instead of the GPU. This is annoying and makes the machine feel slow. I would like to have accelerated hardware rendering back, but I don't know where to start troubleshooting this. All relevant packages seems to be installed. The GPU is detected. But llvmpipe is used for all rendering instead. System info:

There is no /etc/X11/xorg.conf on my system. /etc/X11/xorg.conf.d/ contains a file called 20-displaylink.conf:

Section "Device"
    Identifier  "Intel"
    Driver      "intel"
EndSection

Plus, another file called 90-xpra-virtual.conf which was automatically created:

# Ignore all xpra virtual devices by default,
# these will be enabled explicitly when needed.
Section "InputClass"
        Identifier "xpra-virtual-device"
        MatchProduct "Xpra"
        Option "Ignore" "true"
EndSection

A *systematic troubleshooting guide* would be most helpful/appreciated. Unfortunately, I could not find a suiable one online = one that is specific to this piece of hardware and one that does include a fix, not only diagnosis. P.S.: I have another older computer (an older MacMini) that also has an Intel chipset/GPU, also uses the i915 driver and suffers from the same type of problem (renderer: llvmpipe instead of GPU, even though GPU seems to be "recognzied"). So I am pretty sure that this is related to the upgrade to Trixie/Debian testing. Other than that, I have no idea as where to start troubleshooting this.

The ethernet works fine and everything else seems fine. I have disabled fast boot from Windows 11. I know it's not a hardware issue because my Wi-Fi card (Intel) works on Windows and worked on a previous Debian system I had on another hard drive. I have downloaded iwlwifi, but I am getting errors such as in dmesg:

I don't know what other information would be useful, so just ask and I should be able to provide it. I have spent a good amount of time troubleshooting, but I am new to Linux and don't have a ton of Comp Sci experience.

I have an application with several CPU intensive threads set to the SCHED_RR scheduling policy. I recently starting running this on a system with a hybrid core Intel CPU, and noticed that these threads are always getting scheduled on E cores, which is creating a performance bottleneck. After doing some experiments, it seems that all threads with a real time scheduling policy end up getting scheduled on E cores unless they are explicitly set to a P core by setting the affinity. With SCHED_NORMAL threads, I see the behavior I would expect, with threads getting dynamically scheduled across P and E cores and CPU intensive tasks generally ending up on P cores. I can reproduce this behavior with the stress-ng utility. With this command, I see the CPU stress threads are scheduled on P cores: stress-ng --cpu 4 --timeout 60s However, if I switch this same test to a real time scheduling policy (RR or FIFO), the threads are always scheduled on E cores and perform worse: stress-ng --sched rr --cpu 4 --timeout 60s What could cause this behavior? Could I be missing something in my kernel configuration? Or is it expected that the scheduler prefers E cores for real time threads? As a workaround I could just force threads on to P cores, but I'd prefer to use dynamic scheduling if possible to take advantage of both core types. Kernel version: 5.14.0-427.76.1.el9_4.x86_64+rt CPU: Intel Core i9-12900

I'm new to Arch Linux. I installed it on my laptop(LG Gram) it seem fine post installation. I don't remember my wlan works post installation because I used wired. But, when I turned on my laptop today wlan interface load fails. I lastly installed wine 5.1 yesterday but I don't think is the reason. I searched other cases in google but I couldn't find any valid solutions. How can I fix my driver?

I found someone [similar issue](https://bbs.archlinux.org/viewtopic.php?id=243691) with me but his solution is not working for me. I added

and grub-mkconfig again but it didn't work. My Network Interface is not even loaded so I can't do something like

I upgraded my Wireless Card from Intel Wireless 9560 to AX200. I have Dual Boot Windows OS & Ubuntu 20.10 on my HP Omen. I updated my wireless driver on my Windows 10 environment. Everything working perfectly.Every time I boot into my Ubuntu 20.10, I have to connect to my hidden Wifi every time. I tried to see if Ubuntu recognizing the AX200 drive. This is what I found: krillavilla@krillavilla-OMN:~$ sudo dmesg | grep iwlw [sudo] password for krillavilla: [ 3.259537] iwlwifi 0000:04:00.0: enabling device (0000 -> 0002) [ 3.269345] iwlwifi 0000:04:00.0: Direct firmware load for iwlwifi-cc-a0-56.ucode failed with error -2 [ 3.270894] iwlwifi 0000:04:00.0: api flags index 2 larger than supported by driver [ 3.270911] iwlwifi 0000:04:00.0: TLV_FW_FSEQ_VERSION: FSEQ Version: 89.3.35.22 [ 3.270915] iwlwifi 0000:04:00.0: Found debug destination: EXTERNAL_DRAM [ 3.270917] iwlwifi 0000:04:00.0: Found debug configuration: 0 [ 3.271217] iwlwifi 0000:04:00.0: loaded firmware version 55.d9698065.0 cc-a0-55.ucode op_mode iwlmvm [ 3.271333] iwlwifi 0000:04:00.0: Direct firmware load for iwl-debug-yoyo.bin failed with error -2 [ 3.358293] iwlwifi 0000:04:00.0: Detected Intel(R) Wi-Fi 6 AX200 160MHz, REV=0x340 [ 3.561857] iwlwifi 0000:04:00.0: base HW address: e0:d4:e8:53:eb:b1 [ 3.577475] iwlwifi 0000:04:00.0 wlp4s0: renamed from wlan0 krillavilla@krillavilla-OMN:~$ lspci -nn | grep Network 04:00.0 Network controller : Intel Corporation Wi-Fi 6 AX200 [8086:2723] (rev 1a) **UPDATE** I went to the Intel website to load the driver using the instruction provided on this link Intel Linux Wireless Driverl I still get kicked off my Wifi randomly ***UPDATE*** It's been 4 hours and I did not get kick off my wifi yet.

I already disable Fast boot startup and my secure BIOS is disabled since I have Windows OS dual boot. Now, my issue is my throughput on my Windows 10 OS speed test is over 120mbps download speed. On my Ubuntu 20.10, I get a 55mbps download speed. All the other devices connected to my TP-Link AX6000 getting over 200+mpbs download speed. my laptop is the only device that getting less than 200mbps. Why is that? ***UPDATE*** I restart my computer and Ubuntu 20.10 didn't connect to my Wifi automatically. I have to go to Network Manager and connect it manually. ***UPDATE*** Its been several hours and I didn't get kicked off my wifi but I still have to connect to it manually after restart or reboot. I have 4 questions I need help with: 1. Can someone help me resolve this error message: [3.484752] iwlwifi 0000:04:00.0: enabling device (0000 -> 0002) [3.498326] iwlwifi 0000:04:00.0: Direct firmware load for iwlwifi-cc-a0-56.ucode failed with error -2 2. Can someone help me figure out why Ubuntu won't connect to my Wifi Automatically after reboot/restart? 3. Can anyone explain to me why my Windows 10 OS has way faster Link speed/throughput than my Ubuntu 20.10? Is there a fix for this issue? 4.Is there a way to install WPA 3 and 802.11ax on my Ubuntu laptop?

When trying to run gnome-control-center, I get the following errors:

libEGL warning: DRI3: Screen seems not DRI3 capable
libEGL warning: DRI2: failed to authenticate

gnome-control-center then proceeds to not open. Running it with sudo will result in a blank window opening. I have tried uninstalling and reinstalling, updating and upgrading my system, but nothing seems to work. I'm running Zorin 15 Bionic on a i5-6200U, with a NVIDIA GTX 940M GPU.

* * * From the search results, I see this a [known issue](https://duckduckgo.com/?q=imac+2017+linux+no+sound) . Most topics don't provide a solution. [This topic](https://bbs.archlinux.org/viewtopic.php?id=277990) seems to be similar, but it points to [this kernel module](https://github.com/egorenar/snd-hda-codec-cs8409) which I don't know how to use. Also, I tried sudo nano /etc/modprobe.d/alsa-base.conf

I have choppy video and my windows are choppy when I move them around. Also when my PC turns off monitor it does not turn off normally but like the cable was unplugged. I guess I need to install a driver for my new 'graphics' chip. Can someone please provide the 'best' way of installing graphics drivers for my Celeron G1820 CPU. Here is what I get from lspci: 00:02.0 VGA compatible controller: Intel Corporation Xeon E3-1200 v3/4th Gen Core Processor Integrated Graphics Controller (rev 06) I can provide any additional info if needed.

I have this hardware: - Lenovo thinkpad x390 yoga - Lenovo thinkpad thunderbolt 3 dock gen 2/Workstation dock gen 2 and this software: Wayland + sway I would like to be able to connect laptop to the dock and it will charge it and connects external display using HDMI or display port. None of these think is happening. What should I do to be able to use the dock ? Thankyou for help ## Diagnostics cat /proc/version outputs

## What I tried - Rebooting - Updating kernel - Updating firmware

My application requires maximum single-thread performance and suffers from switching to the Intel E cores. I am looking for a way to disable E cores on Intel i9-12900K on my Ubuntu 20.04 machine without access to bios (it is a rented dedicated server). Or for any possible way to distinguish such cores and assign CPU affinities using taskset to exclude them from execution. Tried to find the answer myself in Google. Only found that there are indeed scheduler issues for now, but there is no clear fixes or workarounds available for my problem.

I keep getting disonnected and dmesg keeps repeating this,

What does this mean, how can I fix it? Currently using version 20210818-1 of iwlwifi.

About a month ago, one of the 4 drives in my array went clicky. I was able to identify the 2nd drive (sdb of sd[a-d]) was the bad drive and thought I failed/removed it. After getting a replacement drive and getting as much data as possible, I don't think I'll get anywhere without editing imsm metadata.

Interesting! So It looks like the metadata is coming from /dev/sda, Disk00. This is the first time I've noticed 4 drives, and that "Disk01 Serial : 57E07H1MS:0" doesn't look "WD" like the other "WD" drives. I wouldn't be surprised if I missed something in the --remove process. I've had access to the "Intel virtual raid on cpu intel vroc for linux user guide" pdf for lots of insight. The "update-subarray" stuff looks like what I'll need to research next to figure out [Volume0]'s Failed disk and Disk01's metadata. I'd expect something like

# mdadm --update-subarray=0 --update-id=ffffffff --state=failed /dev/md0

but that was from piecing together some examples I found in the "Linux-Intel-VROC-TPS-335893.pdf" I found. Any help getting the array --run-ing again would be appreciated.

> Remove kms from the HOOKS array in /etc/mkinitcpio.conf and [regenerate the initramfs](https://wiki.archlinux.org/title/Regenerate_the_initramfs) . This will prevent the initramfs from containing the nouveau module making sure the kernel cannot load it during early boot. The [nvidia-utils](https://archlinux.org/packages/?name=nvidia-utils) package contains a file which blacklists the nouveau module once you reboot. The above quote from the Arch Linux wiki page for [NVIDIA](https://wiki.archlinux.org/title/NVIDIA) says to remove the kms hook after installing nvidia drivers so that nouveau can't conflict with them (or at least I think that's what it means!). However upon removing it, I experience problems with my vconsole tty on boot, including the font not being set correctly and the login prompt being (visually) corrupted by a kernel error msg:

[[bottom 20% of an ascii art defined in /etc/issue that had displayed fully when kms wasn't deleted]]
emmy login: [    5.559980] i915 0000:00:02.0: [drm] *ERROR* Failed to probe lspcon

Then I saw that even with the kms hook added lsmod | grep nouveau shows nouveau isn't loaded. So what's the point of removing the kms hook when it seems that all it does is cause errors from weird loading orders of modules? And what does the hook actually do? Here is my journalctl for both cases (I am using a intel i915 integrated graphics card + an nvidia GTX 1650 card): KMS removed: journalctl -b | grep -E "nvidia|drm|fbcon|i915"

I don't see what the difference is because both end up with my i915 card using the framebuffer.

My laptop got 2 graphics cards, something very similar to: https://www.linuxbabe.com/desktop-linux/switch-intel-nvidia-graphics-card-ubuntu . I would like to have **Intel** graphic card for display purpose only, and **NVidia** graphic card for heavy computation (GPGPU). My questions: 1. Do I still need to install NVidia driver? It seems the driver is **for display ONLY** ? So, is it a must to install NVidia driver if I do **NOT** expect to use NVidia card for display ? 2. Without NVidia driver, will those 3rd-party libraries still be able to run? For instance, Tensorflow, etc.? From https://docs.nvidia.com/deploy/cuda-compatibility/index.html , it's clearly written that: > To build an application, a developer has to install only the CUDA > Toolkit and necessary libraries required for linking. > > In order to run a CUDA application, the system should have a CUDA > enabled GPU and an NVIDIA display driver that is compatible with the > CUDA Toolkit that was used to build the application itself. It looks to me: - In order to run CUDA application, I have to install NVidia Driver, which enables the NVidia graphics card. - However, the NVidia Driver is for display purpose. In order to use it, I have to use NVidia graphics card for display, rather than using Intel card for display??? Sorry for my naive question. A kind of conceptually confused... Looking forward to the answer.

As far as I understand, the number of CPUs in my computer should be given by CPU = Thread(s) per core x Core(s) per socket x Socket(s) Here are the first few lines of the lscpu output: $ lscpu | head -n18 Architecture: x86_64 CPU op-mode(s): 32-bit, 64-bit Address sizes: 46 bits physical, 48 bits virtual Byte Order: Little Endian CPU(s): 22 On-line CPU(s) list: 0-21 Vendor ID: GenuineIntel Model name: Intel(R) Core(TM) Ultra 7 155H CPU family: 6 Model: 170 Thread(s) per core: 2 Core(s) per socket: 16 Socket(s): 1 Stepping: 4 CPU(s) scaling MHz: 14% CPU max MHz: 4800.0000 CPU min MHz: 400.0000 BogoMIPS: 5990.40 What’s going on? 2 × 16 = 32, not 22. Even running nproc --all shows 22. Am I missing something?

First: virtual sound throuch RDP (**Remote Desktop Connection**) i.E. ***NoMachine*** works brilliantly, only the internal speakers and head phones don't give a sound. Sound drivers (**sound open firmware are installed by github source v2.2 (before most latter v2.12) **). **Sound card is intels *snd_hda_intel*.** I have followed the few links found on the net regarding Linux Mint or Ubuntu 22, which always are similar like: - install ALSA - Reinstalling sound system and restarting alsa - (re)install pipewire - install and configure hdajackretask (this is the least promising way IMHO) incl. restarting alsa,

So far no results. The only thing is working, is if you connect via NoMachine the sound is transferred to the remote computer. So I consider the sound is produced but somewhere between the layers of Abstraction of the OS down to the HW there is an issue. I beg you for your ideas, or solution (trees)!

[EDIT 3] Picture of Alsamixer. Is the device muted if its green around the number down in the column, or vice versa? Plus List of soundcards, which is actually default and sof-hda-default. But changing the volume or muting in alsamixer does not change the missing sound from the speakers and changes made don't survive a boot:

My 2019 iMac (18,3) has no sound through the speakers/headphones and no Mic when running Linux: **it works as expected on OSX**. I am posting here because this appears to be a Linux issue, as I have three different distros installed -- **Manjaro** (kernel *5.6-x86_64* (though I have tried 6.0 too)); **Fedora 31** (kernel *5.1.20-300*); and **Ubuntu 19.10** (kernel *5.3.0-45-generic*) -- and none of them produce sound or record it from the mic. The Audio Device from lspci is Intel Corporation 100 Series/C230 Series Chipset Family HD Audio Controller (rev 31). It also appears to control the PCI Bridge and the USB controller. I have posted more information here . I have looked at both pavucontrol and alsamixer, but have found nothing to suggest that the operating systems don't think the Audio Device is working. It's just that no sound comes out. In pavucontrol, the Configuration is set to HDMI off, and Built-in Audio as Analog Stereo Duplex -- though none of them change the outcome. In alsamixer, the Chip is identified as Cirrus Logic Generic, which is incorrect, and there are no speaker/headphone/anything columns other than PCH. As suggested in this thread , I tried to fiddle with /etc/modprobe.d/modprobe.conf by adding options snd_hda_intel model=intel-mac-auto and various other iterations (e.g., options snd_hda_intel model=imac27 see here for why). Installing XFCE and modifying the settings there did not work for me. There are similar posts about not getting sound of of the newer (post-2017) iMacs, which can best be found by just searching Google with snd-hda-intel imac 18,3. That the problem spans all distros (Fedora ; LinuxMint ; Ubuntu ; Manjaro ) suggests a kernel or driver issue. **Any idea either (A) how to fix or (B) where I can post this get someone to build this audio device into the kernel??** Adding dmesg. There are no recent journalctl entries related to sound. This is for Manjaro 20.0 running 5.6.5-1-MANJARO.

Still no sound.

After a fresh installation of Linux Mint on my laptop I notice that audio isn't working, and I see dummy input/output. After this I had tried a lot of solutions. After adding

options snd-hda-intel model=generic

in /etc/modprobe.d/alsa-base.conf I could see only HDMI output. This mean that headphone and integrated speaker are unavailable. This seems like that SO can't know about internal speaker, microphone and audio jack. How could I fix? My system information: **System info** dmesg -l err,warn ### Update I tried different kernels: 5.11, 5.8 and 5.4. This is a new laptop, this is the first installation. I don't know if should work... Today, something strange has happened. I connect my headphones to randomly check if something has been changed (I don't know why) and I heard some noise from the laptop speakers. Then I try to put my smartphone line out in the computer jack with an AUX cable. And I can hear the sound of the smartphone thought the speakers. When I change the volume, nothing happened. Why? It could be some physical problem of the sound card? #### Removing my addiction in /etc/modprobe.d/alsa-base.conf

After unlocking disk the usual verbiage changed and there was a message about downloading firmware. I want to find out what was going on so I tried dmsg -

% sudo dmsg
[    0.000000] microcode: microcode updated early to revision 0xf8, date = 2023-09-28
[    0.000000] Linux version 6.1.0-30-amd64 (debian-kernel@lists.debian.org) (gcc-12 (Debian 12.2.0-14) 12.2.0, GNU ld (GNU Binutils for Debian) 2.40) #1 SMP PREEMPT_DYNAMIC Debian 6.1.124-1 (2025-01-12)

The microcode message is very vague. Is it unusual? How can I determine what firmware I have, what I should have, and what is available? ------------------ Edit: top of changelog.Debian

      Improper Finite State Machines (FSMs) in the Hardware logic in some
      4th and 5th Generation Intel Xeon Processors may allow an authorized
      user to potentially enable denial of service via local access.
    - Mitigations for INTEL-SA-01079 (CVE-2024-23918)
      Potential security vulnerabilities in some Intel Xeon processors
      using Intel SGX may allow escalation of privilege.  Intel disclosed
      that some processor models were already fixed by a previous
      microcode update.
    - Updated mitigations for INTEL-SA-01097 (CVE-2024-24968)
      Improper finite state machines (FSMs) in hardware logic in some
      Intel Processors may allow an privileged user to potentially enable a
      denial of service via local access.
    - Mitigations for INTEL-SA-01103 (CVE-2024-23984)
      A potential security vulnerability in the Running Average Power Limit
      (RAPL) interface for some Intel Processors may allow information
      disclosure.  Added mitigations for more processor models.

After upgrading my VPS from a shared CPU (intel) to a dedicated CPU (amd), I get a kernel panic on bootup, including if I boot into recovery mode. I have managed to use the rescue console to get to the disk (and I'm currently copying the files off it), but what can I try or investigate to get it working again? I also can't find the kernel panic in any logs from rescue mode (and I don't seem to be able to scroll in the console to be able to see what preceded it). Is there any way to get at those logs?
