I found out that manually adding resolution of my monitor fixes my problem of not getting the right resolution in the secondary monitor. I followed the steps in this link which worked out for me. https://www.tecmint.com/set-display-screen-resolution-in-ubuntu/ 1 : list all active monitors. $ xrandr --listactivemonitors 2 : To add a missing or custom display ...

I had a similar problem on Ubuntu 20.04.3. This problem appeared when I enabled the "Dock auto-hide" option in the settings. Disabling the Ubuntu Dock auto-hide feature fixed it. Also, try setting up the Dock on the main monitor.

Pop_OS is unsupported by Canonical, you should consult with developers of this system. In Ubuntu xrandr works in Xorg session. To switch to Xorg : log out . Click gear in bottom-right corner and select Ubuntu on Xorg. Log in. Check a name of your video output , current video mode and allowed refresh rates : xrand Then switch to some mode (example for ...

I know this is old question. But I want to add my workaround here for the people that reach this question via Google search. My problem span already Ubuntu 16.04, 18.04 and 20.04 I have a Dell laptop and Dell external screen. My second screen goes directly into power saving mode after boot and stays in power savings mode. The cause of this is. Every time I ...

I was also trying to connect an external HDMI monitor to my system but was not happening. So I changed setting in BIOS to enable Virtualization Environment and it worked. It was detected in windows but not on ubuntu so BIOS is the option to change.

I had exactly the same symptoms (desktop frozen when disconnected from monitors, but keyboard lights and ssh to it still worked), but likely a different root cause. Nevertheless, I'm sharing my outcome here. I have a Dell XPS 9500 running Ubuntu 20.04 with NVIDIA driver 470.82. My setup was the laptop connected to a docking station (inconsequential, I think) ...

The best answer i have is to run the whole computer on few virtual machine, one per screen or group of screens, but I hate that solution. The reason is the loss of 2d/3d graphics acceleration and the need to switch the keyboard/mouse input from one machine to the other (by exiting mouse-grab or full-screen or hitting a key macro)

Just to get this out of the "unanswered" category: the solution which worked so well for me is incredibly simple compared to all of the things I tried. It is explained well here: https://askubuntu.com/a/1130337/8 and it really only involves a few steps: sudo apt install autorandr, and arrange according to your preference using xrandr or even with ...

I figured it out, for some reason, GRUB (or another bootloader that might be installed) disables the graphics card (not sure if it disables the drivers, the ports, or the card itself). So to force the graphics card to remain enabled, you need to add amdgpu.dc=0 to the boot file. You can do that by running the command: kernelstub -a "amdgpu.dc=0" ...

Okay, so if anyone suffering from the same problem I had, here's a possible fix. I've reinstalled Ubuntu completely(20.04.03 LTS, minimal installation and 3rd party drivers). Details: (BIOS) Double check on SecureBoot(I wiped the keys as well), TPM off. SGX enabled Used nomodeset to boot into the system(or else I'll be stuck in a login loop with the 2nd ...

Lacking an extension, you could brew a little dialog yourself using Zenity (installed by default on Ubuntu), or using Rofi or dmenu, in a script that can be summoned using an application launcher (Zenity, less "natural" for rofi/dmenu) or using a custom shortcut key.

I hope I helped to clarify the problem. "Do not connect external displays to the USB-C connector 1 and the HDMI connector 2 at the same time. Otherwise, only the external display connected to the USB-C connector 1 will work by default. To change the priority between the USB-C connector and the HDMI connector, start the ThinkPad Setup program. See “” on ...

It is possible to get two ttys on two monitors by mapping them to corresponding frame buffers using Kernel parameters. You can even have background refresh by using fb terminal instead of the default tty (Getty in most cases) Check this https://unix.stackexchange.com/questions/556782/tty-dual-monitors for more clues.

I had a similar problem. Additionnally I use a tweaked version of Ubuntu using X11 instead of Wayland. I found some instruction that helped me solve the problem. https://unix.stackexchange.com/questions/358992/cursor-flickers-with-xrandr-scaling The trick I used is the additional xorg conf file: /etc/X11/xorg.conf.d/20-intel.conf Section "Device" ...

It seems that this is a problem with NVIDIA drivers. I logged in to a text terminal and type sudo apt remove --purge nvidia* and then reboot. Then I reinstalled the Nvidia drivers.

I wanted to elaborate on @codlord's great suggestion: Mapping xdotool getactivewindow windowsize 110% 110% to a keyboard shortcut did exactly the trick (i.e., under Settings) - this should work regardless of the desktop manager (Gnome, Cinnamon, XFCE, etc.). You can quickly first test it out on a terminal window by entering the above command into that very ...

Through the centuries I have since figured this out. The solution is not to apply 0.5x0.5 scaling, but to adjust the DPI. I didn't think the DPI adjustments were working because you need to refresh i3 to see them (Mod+shift+r) I added the following to ~/.Xresources: Xft.dpi: 192 I then ran the following commands: xrdb -merge .Xresources exec i3 I then ran ...

Have a look at eyesome Multi-monitor brightness and color temperature based on sun times. Below is a snipped from the Ask Ubuntu answer. eyesome Eyesome is a bash script running as a daemon and sleeping most of the time 24/7. It automatically adjusts screen brightness (and optionally gamma too) for your laptop display via hardware interface and up to two ...

Solution was to disable secure boot properly, apt upgrade once again for Nvidia drivers needed upgrade again and change primary selected GPU to Nvidia ( after Nvidia drivers installation and reboot it changed GPU to integrated Intel...) Thank You all

At the suggestion of ChanganAuto, checking "Force Full Composition Pipeline" for the 60Hz monitor fixed the screen tearing. The check box can be found by going to "X Server Display Configuration" in nvidia-settings, selecting the desired monitor, and then clicking "Advanced" at the bottom.

This happened to me! (20.0.4) The easiest workaround I could find was making the second monitor the primary monitor. After that all dragging worked!

Something changed in the Ubuntu OS or the BIOS setup. A driver update, multi-monitor was turned off in the BIOS setup, an upgrade messed with a config file, new driver version defaults to single monitor configuration, proprietary nVidia driver kick out by nouveau open-source nVidia driver. Try nvidia-settings, Look at the monitors (or screens) section. Try ...

Try this: From your terminal, run: sudo apt install nvidia-settings once the package installs, simply type nvidia-settings in the terminal to open the Nvidia X Server Settings app. Inside the app, you will find multiple tabs / pages of configuration options specifically for systems running on a Nvidia gpu with multiple displays. Take your time and configure ...

After looking into VXDguy's suggestion further, I discovered that I was able to get dual monitors working with 1080p x 60Hz OR 4k x 30Hz. A little more research yielded the answer: My 90W Lenovo 40A2 dock for the P51s has dual DisplayPort 1.2. Apparently DisplayPort 1.4 is required to run dual 4k x 60Hz. I plan to content myself with a 2k x 60Hz compromise ...

To fix it install the GPU drivers. Open the terminal and run ubuntu-drivers devices -> one of the drivers should be marked as distro non-free recommended so choose this one with sudo apt install <driver_name> && sudo reboot Alternatively install the recommended proprietary graphics drivers automatically with sudo ubuntu-drivers autoinstall &...

This is because Remmina doesn't fully supports Wayland yet. Since 21.04 Ubuntu uses Wayland as the default display server protocol. You can switch to Xorg mode when logging on to desktop and Remmina will work as good as before. You can change the display server on the Ubuntu login screen. If your desktop configured to auto login you have to log out and then ...

I got other solution. Just to give some context, i have 4 screens like shown in the picture and i had problems changing from the top one to the bottom middle one. To solve this without removing the dock from the other screens, i went to dash to dock settings, intelligent autohide settings and disabled push to show.

As Gertlex correctly pointed out, the problem is rooted in the xserver (see this issue). Fortunately, the problem has been solved and the solution been merged into the xserver 1.20 branch. The first release to contain those fixes is 1.20.12 (see repo history), which is not currently available before Ubuntu 21.10 (see ubuntu's package repository). Hence, I ...
