I'm trying to connect to use remote servers in multi monitor setup with following command

xfreerdp3 /d:foobar.intranet /u:myuser /v:xx.xx.xx.31 \
    +clipboard +sound -wallpaper /cert:ignore \
    /multimon:force /monitors:0,3

The problem is that both monitors are mirrored in full screen and are not interactable (it's like they show a default desktop without any input). My monitors are:

❯ xfreerdp3 /list:monitor
      *  2560x1440	+2560+0
         1920x1080	+7680+0
         2560x1440	+5120+0
         2560x1440	+0+0

The thing which makes no sense to me is that in the window preview both monitors are rendered correctly but if opened it's still frozen. I'm using CachyOS with KDE Plasma, both on the newest default release.

I am using Ubuntu 14.04LTS with dual Monitor. I am unable to figure out the problem occurring with the mouse pointer. The mouse pointer blinks and at times it disappears.

I have been doing some research and it looks like my xrandr has some issues. The problem is I connect a HDMI monitor and it shows that is disconnected; somehow the port is not working properly. I'm using Manjaro. xrandr output: Screen 0: minimum 8 x 8, current 1920 x 1080, maximum 32767 x 32767 eDP1 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 380mm x 210mm 1920x1080 60.03*+ 48.01 1400x1050 59.98 1600x900 60.00 1280x1024 60.02 1280x960 60.00 1368x768 60.00 1280x720 60.00 1024x768 60.00 1024x576 60.00 960x540 60.00 800x600 60.32 56.25 864x486 60.00 640x480 59.94 720x405 60.00 640x360 60.00 DP1 disconnected (normal left inverted right x axis y axis) HDMI1 disconnected (normal left inverted right x axis y axis) VGA1 disconnected (normal left inverted right x axis y axis) VIRTUAL1 disconnected (normal left inverted right x axis y axis) As you see, it show as disconnected but the HDMI is connected. Is there any way to solve this?

I have a laptop and a separate screen I plugged via HDMI what I want to do that I use the laptop screen for workspace1 and external screen for workspace2 this may explain butter: - each workspace will be "glued" to one monitor. - when a workspace is selected as "active" it receives the mouse + keyboard inputs. - windows which have been opened on (active or non-active workspaces) remain displayed on the monitors. right now I'm using manjaro and Xfce and AMD GPU what I find out from my research is that Xfce doesn't support this future so I want to know what are the best windows managers options to do such a thing and how to do it

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 have two monitors, one attached to my Nvidia graphics card using HDMI, the other one using VGA (using a DVI-VGA adapter). Most full-screen games (that even recognizes that there are two monitors) uses the secondary monitor. The primary monitor is correctly set when I check from nvidia-settings, xrandr or KDE system settings. My current workaround is to simply disable monitor 2 when playing a game, but that's not satisfying. How can I effectively set the primary screen?

I have an external monitor on my laptop, but it's placed wrong on the right instead of on the left from of my laptop display. When I go to displays configuration on my Fedora 42, I can rearrange it. However, when I click Apply all my windows get closed and my Plasma session resets. After I log back in, the monitors are still placed in the wrong way. I cannot change the settings. I'm using X11, the problem doesn't appear on Wayland. Using xrandr doesn't help – the same behavior repeats. This is the output of lspci | grep VGA: 00:02.0 VGA compatible controller: Intel Corporation TigerLake-H GT1 [UHD Graphics] (rev 01) 01:00.0 VGA compatible controller: NVIDIA Corporation GA106M [GeForce RTX 3060 Mobile / Max-Q] (rev a1) How to rearrange my displays so that it doesn't break my DE?

### Background I've had this issue in one way or another for a long time now (years), and in multiple configurations. I've updated the driver & kernel on multiple occasions, and at this point I'm really at a loss as to where the culprit is. It seems to be some kind of race condition where if one monitor is 'ready' before the other, the other just gets 'No Input', despite xrandr (and i3) thinking it's connected and should be working. ### Old setup - One 4K monitor - One 1080p monitor Behavior: Both monitors goes to sleep (from inactivity), and upon moving the mouse only one of them (the 1080p monitor) correctly wakes. The other one wakes a few seconds later, but then shows 'No Input'. Workaround: - Run xrandr.sh (old version, see below for the new version) - I can't say for certain if I had to do something else to get it working (the whole process became muscle memory more or less...) ### New setup - One 4K monitor (same as previous setup) - One 4K monitor (new) Behavior: Similar behavior, but now the behavior applies to the *new* monitor. The old one behaves just fine (just like the old 1080p monitor). Workaround 1 (remembering to wake the monitor first): - (*before waking screens by moving mouse/keyboard*) Wake 'slow' screen by using menu buttons on monitor - When monitor has completed resume from standby and shows menu items, move mouse/keyboard to wake monitors. - Both monitors work correctly! Workaround 2 (forgetting to wake the monitor first): - (*move mouse/keyboard*) Both monitors wake. One works correctly, the other takes more time to wake from suspend and then just shows 'No Input'. - Run xrandr --output HDMI-0 --off, which puts the monitor back in standby. - Apply workaround 1. - Both monitors work correctly! ### Details Nvidia driver version (from Arch repos): 455.45.01-6

### Attempted solutions Over the years, I've googled several times for similar issues, and I've never really found anything promising. I used to think it was something weird with the old 4K monitor (like a bad EDID), but now that I'm having the same issue with the new monitor I've discarded that suspicion. I've found a lot of threads about screens failing to resume after *suspend* (usually fixed with modeset), but in my case there's no real suspend happening, it's simply a screen off/blanking (and it only happens for one of the monitors!). Furthermore, I've also not found any issue similar to mine with respect to the 'race condition'-like nature of the issue/workaround.

I have total of four monitors. One (1680x1050) is connected to integrated Intel display adapter, and three (1440x900 and two 1920x1080) are connected to dedicated ATI display adapter. With certain XRandR configurations some monitors have their display area cropped, so that for example lower part of the screen is not usable. I'd like to use configuration like this one: xrandr \ --output VGA-1 --mode 1440x900 --pos 780x1080 --rotate left \ --output HDMI2 --mode 1680x1050 --pos 0x30 --rotate normal \ --output HDMI-3 --mode 1920x1080 --pos 1680x1080 --rotate normal \ --output DVI-0 --mode 1920x1080 --pos 1680x0 --rotate normal But the lower part (below the bottom edge of the bottom right screen) of the bottom left screen is cut off: On the other hand, this configuration works: xrandr \ --output VGA-1 --mode 1440x900 --pos 780x1050 --rotate left \ --output HDMI2 --mode 1680x1050 --pos 0x0 --rotate normal \ --output HDMI-3 --mode 1920x1080 --pos 1680x1080 --rotate normal \ --output DVI-0 --mode 1920x1080 --pos 1680x0 --rotate normal , as shown here: Also this configuration works: xrandr \ --output VGA-1 --mode 1440x900 --pos 780x0 --rotate left \ --output HDMI2 --mode 1680x1050 --pos 0x1440 --rotate normal \ --output HDMI-3 --mode 1920x1080 --pos 1680x1440 --rotate normal \ --output DVI-0 --mode 1920x1080 --pos 1680x360 --rotate normal , as shown here: In addition, the configuration below works xrandr \ --output VGA-1 --mode 1440x900 --pos 780x1080 --rotate left \ --output HDMI2 --mode 1680x1050 --pos 0x30 --rotate normal \ --output HDMI-3 --mode 1920x1080 --pos 1680x1440 --rotate normal \ --output DVI-0 --mode 1920x1080 --pos 1680x0 --rotate normal as shown here: **UPDATE:** Strangely, I managed to get the wanted layout by command sequence: xrandr \ --output VGA-1 --mode 1440x900 --pos 780x1080 --rotate left \ --output HDMI2 --mode 1680x1050 --pos 0x30 --rotate normal \ --output HDMI-3 --mode 1920x1080 --pos 1680x1440 --rotate normal \ --output DVI-0 --mode 1920x1080 --pos 1680x0 --rotate normal xrandr \ --output HDMI2 --mode 1680x1050 --pos 0x30 --rotate normal \ --output DVI-0 --mode 1920x1080 --pos 1680x0 --rotate normal \ --output VGA-1 --mode 1440x900 --pos 780x1080 --rotate left \ --output HDMI-3 --mode 1920x1080 --pos 1680x1080 --rotate normal \ --primary so that it works on freshly started Xorg instance, but I don't have a clue why it works. Besides, that solution seems a bit ugly. Can anybody enlighten me on this issue, please? My OS is Arch Linux, window manager is i3, and the version of XRandR is 1.4.2. Xorg configuration files have only InputClass and Files sections.

I have two monitors, both originally 1920×1080 (landscape). I want to rotate both to portrait mode so that their effective resolution becomes 1080×1920, and then stack them vertically using xrandr. Here’s what I want to achieve: 1. Both monitors in portrait orientation 2. HDMI1 on top 3. DP2 on bottom 4. Total virtual screen resolution: 1080×3840 5. Preferably with HDMI1 as the primary display ❌ What I tried and the result: I followed this thread, and it worked for landscape mode (3840x1080). This is my Python code where I am executing the xrandr commands using subprocess.

cmds = [
        ["xrandr", "--output", secondary, "--same-as", primary],
        ["xrandr", "--output", primary, "--panning", "1080x3840+0+0/0x0+0+0/0/0/0/0"],
        ["xrandr", "--output", secondary, "--pos", "0x1920"],
        ["xrandr", "--output", primary, "--panning", "0x0"],
        ["xrandr", "--output", secondary, "--panning", "0x0"],
        ["xrandr", "--output", primary, "--auto", "--pos", "0x0", "--primary"],
        ["xrandr", "--output", secondary, "--auto", "--pos", "0x1920"]
    ]

**Result:** 1. On one screen, the Chrome video is displayed half (HDMI1) which is correct, and the other half should be displayed on another screen (DP2). **But DP2 is not showing the video that I am playing in Chrome.** what could be the problem? Your suggestion will be greatly appreciated.

I'm having a problem after installing Fedora 36. I keep getting a half white screen while using an external monitor. I'm using my laptop and a monitor, but my monitor is only showing a white screen. When I hover my mouse to the monitor, it starts showing half screen. I dont get the message error anymore but the screen still half blank. --- My laptop has an Nvidia RTX 2060 and a AMD Ryzen7 3750

I’m running Fedora 42 installed on an external NVMe (2TB) drive connected to my MacBook Pro (Early 2015). My system setup is as follows: CPU: Intel i7 (Broadwell, MacBook Pro) Graphics: Intel Iris 6100 Fedora Version: Fedora 42 (Workstation) Display Adapter: JUA365 - USB™ 3.0 to Dual HDMI™ Multi-Monitor Adapter (DisplayLink based) DisplayLink Driver: Installed EVDI module: Loaded Secure Boot: Disabled DisplayLink service: Running fine Everything seems installed properly — but the external monitor still doesn’t turn on or get detected. I've tried: Manually restarting displaylink-driver.service Reinstalling EVDI via DKMS Reconnecting and powering monitor Verified logs (journalctl) — no clear errors I’m wondering if anyone using JUA365 or similar DisplayLink adapters has encountered and solved this issue on Fedora 41/42? Is there a known issue with DisplayLink adapters (like JUA365) on Fedora 42? Could this be a missing udev rule or a permissions/device node creation issue? Anyone using a similar setup successfully? Any tips, logs to check, or workarounds would be greatly appreciated. Thanks in advance!

I am using Ubuntu MATE 18.04. I believe it uses LightDM as display manager. I have 2 monitors connected to the same device (Intel HD onboard graphics, with 2 ports, one HDMI, one VGA). Because of the nature of the applications I run, I need to have 2 separate X11 screens. I would need to move the mouse between them, but other than that they should be independent. I should not be able to move windows between monitors. I believe that a setup with one display and 2 screens, with one monitor per screen, would work. Using the display manager GUI app I just get a monitor as extended, and it is on the same screen. - Am I correct that one display, with 2 screens, with one monitor per screen, would do what I want? - And how would I set it up?

# General overview I connected trough VGA cable a second screen to my laptop running i3, but the second screen stay black. The second screen just show a message “No signal” some seconds, then “Entering sleep mode” and become black. Strangely, when I disconnect the VGA cable, the screen wake up. #### Desambiguiation I read here in their that people who get trouble shooting in second screen with i3, get a black screen but with an appearing cursor. In my case, I see nothing. The screen is totally black. #### Softwares’s versions I am using - i3 4.22 - Debian 12 # What I did ## Analyse the situation First I saw what xrandr détect.

## Trying to force the display on the second screen So, I try to configure DP-2 as the second screen with:

xrandr --output DP-2 --auto --right-of eDP-1 --mode 1280x1024 --primary

But then the second screen doesn’t work either. The Window Manager act like if a second screen exist, but in fact the second screen stay black as described before. # The question What to do to make the second screen work?

How should I configure this menu to can turn on all screens? **Info** *-display description: VGA compatible controller product: G98M [Quadro NVS 160M] vendor: NVIDIA Corporation physical id: 0 bus info: pci@0000:01:00.0 version: a1 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress vga_controller bus_master cap_list rom configuration: driver=nvidia latency=0 resources: irq:31 memory:f5000000-f5ffffff memory:e0000000-efffffff memory:f2000000-f3ffffff ioport:df00(size=128) memory:f4000000-f401ffff @terdon > Have you tried simply setting the Dell screen to "on"? Right now I was using the Dell and 22" screens. When I tried turn on the screen the laptop, LPL (1440x900), choose the option Resolution (to turn on is), and apply settings I received this message: If I choose the option "Auto Fix" the 22" screen turn off and turn on LPL and the Dell remains turn on. > Are you sure your card actually supports running 3 monitors? I don't know if my card support this number of the screens. But I tested the same settings with the another pc, Asus with ATI Mobility Radeon HD 5470 Graphics 1 GB, and the Linux Mint (exactly the same version) and I was the same problem. I know which this laptop, Asus, some time ago, I could turn on this both screens. One of them through HDMI and another VGA. Thanks

I have an HP EliteBook 840 G7 Notebook, with Linux Mint 20.3. My goal is to connect two more monitors to the machine. I have a monitor connected via HDMI port, and a monitor connected via USB-C port. Both monitors at the moment work if connected individually, but if I connect both, the one on HDMI takes over, and no signal goes to the one connected via USB-C. The strange part is that I have been able to work with three monitors for some time, up until (several months ago) I have upgraded the system (from 20.1 to 20.2, I think) ad I lost this ability. After reading this answer I have tried to change settings in the bios (allocated bigger video memory, and "enabled high resolution mode" (something involving USB devices in a dock, and Gigabit NIC), but I had no results.

Recently I began to use my laptop (Dell Inspiron N5020) with an external display. I use the displays side-by-side, internal on the left, external on the right. The problem is, however, that the display on the external monitor seems to be shifted to the right by a few pixels, and at the same time a few pixel wide column from the right edge of the internal display is duplicated on the left edge of the external. On a screenshot this is not visible. I illustrated what I'm actually talking about on this image:  The type of the external monitor doesn't seem to matter. Same thing with a Medion 1680x1050 monitor with VGA connector, and a Dell U2311H through HDMI. Also I tried to set various resolution combinations, and it seems to only happen when the internal monitor is at its native resolution (which is 1366x768) (I have Linux Mint 15 x64 with Cinnamon.)

I'm pretty new to Linux. I'm using Debian 12 on a laptop (and a dock) with the SwayWM wayland compositor. I have 2 external monitors connected to the dock, one landscape (DVI) monitor and another portrait (VGA) monitor. How could I: - Change the arrangement and rotation of the monitors - Set the background of any monitor to an image - Have persistence of everything when I undock and dock again Using Xubuntu, I can easily do everything using Xfce4 Display Settings and xfdesktop. But how do I do the aforementioned in Sway? (I don't need a GUI though since I'm rarely gonna change anything) Any advice would be appreciated. Thanks in advance.

I have an external monitor connected to a thunderbolt dock which I would like to utilize. For whatever reason, the monitor appears to be recognized by the system but fails to display anything. - I can confirm that the cable and monitor are fine, as it works perfectly when booted into Windows - The thunderbolt dock seems to not be the issue, as USB peripherals are working fine - Running swaymsg -t get_outputs shows the built in monitor as eDP-1 and the external monitor as DP-2. There is no indication here that the second monitor would not be working. - Running wdisplays shows a preview of what the second display should look like, so evidently the system is rendering what is meant to be sent to the monitor - When I reboot the machine, the tty output is mirrored onto the second monitor. So evidently it is recognized. - There are no errors in sway --debug - There are no entries in dmesg which appear related to the issue - Running lspci -k | grep -A 4 VGA shows that the video driver is loaded

- I have set the environment variable WLR_DRM_NO_MODIFIERS=1 as has been recommended to solve related issues - I have attempted to install other versions of wlroots to no avail, though I honestly don't know whether this would be expected to fix the problem. - While the refresh rate is very bad during normal use (hence why I am attempting this method), I can successfully use this monitor with an external Nvidia RTX 2060 GPU, connected via thunderbolt 3, with the the noveau driver. I don't really have a sense of how to best approach troubleshooting this problem, so any advice would be appreciated! If there is any additional information that would be relevant, I am more than happy to provide it. System information: - OS: Manjaro 21.1.6 Pahvo - WM: sway 1.6.1 - wlroots 0.14.1-2

I have two identical external monitors, which I have tested in Windows.  They work perfectly with no extra configuration – just connect them and done.  When I boot to my **Debian 8 OS** with the three monitors connected, I can see the mouse moving, but that's all (black screens with mouse moving).
