Display on second monitor misbehaves in portrait mode with Nvidia GTX GPU on Ubuntu 20.04
Solution 1:
I was able to work around this by using sudo apt install arandr
running arandr in terminal and then changing the monitor orientation there.
Solution 2:
I can't enable portrait mode at all for any of my monitors in the display settings. (arandr kind of works, but limits me to 60 Hz.)
However, turns out I can do it in the Nvidia Control Panel or with xrandr. Maybe, as a workaround, you could put something like this in a startup script:
xrandr --output DP-0 --rotate left
You would have to replace DP-0 with whatever output your secondary monitor is connected to, of course.
Specs for reference:
- OS: Ubuntu 20.04 Beta
- GPU: RTX 2060 Super
- Driver: Nvidia 440.64
- Monitor 1: Acer XV273K
- Monitor 2: Asus PG278Q
Solution 3:
Simon Alling's answer worked for me but this is the way I persisted configuration across reboots and user sessions. I saved the xrandr command to a file '~/.config/autostart/setup_monitor_display.desktop', made it executable with chmod +x.
# Wait until GUI is ready
X-GNOME-Autostart-Delay=1
xrandr --output DP-0 --rotate left
Then I added the execution of the script to the startup application list.
- Open Startup Application Preferences
- Click Add
- Fill in the name and comment
- For command do something like
sh -c '~/.config/autostart/setup_monitor_display.desktop'
