Can't change display position to "right of"

[Skrzatu]

I have two monitors (Iiyama and Philips).
In 22.04 I had two separate pulpits on each monitors.

Currently in "Settings -> Displays" I can set it to "duplicate" or "joined".
joined option is inconvenient because, every window I open is by default in the center of the gap between two monitors.

I'am able to change it manually via nvidia-settings but it isn't persistent.

[Daniel van Vugt (vanvugt)]

I wonder if this is due to bug 2060268...

[Daniel van Vugt (vanvugt)]

Are you sure Settings is showing both Iiyama and Philips or is it perhaps showing one of them twice? (bug 2060268)

[Daniel van Vugt (vanvugt)]

If you delete ~/.config/monitors.xml and log in again, can you configure the monitors correctly after that?

[Skrzatu (skrzatu)]

Removing ~/.config/monitors.xml doesn't help.

In the "Settings -> Display" I see two different names. Both monitors are recognized.

I think it is more configuration problem.

[Daniel van Vugt (vanvugt)]

Did you log in again after deleting the file?

Is one of the two different names "Unknown Display"?

Actually xrandr show 3 displays:

I have restarted system after removing monitors.xml.

The third one on the list is "Unknown Display".

[Daniel van Vugt (vanvugt)]

The xrandr output looks correct but the attached MonitorsUser.xml.txt looks suspicious in that it confirms the monitors don't have any separate positional information. If deleting monitors.xml didn't work then next please try:

1. sudo rm /dev/dri/card0 # (should be the "Unknown Display")
2. rm ~/.config/monitors.xml
3. Log in again.

If that works then the issue is just bug 2060268. And unfortunately deleting /dev/dri/card0 will only last until the next reboot.

Removing /dev/dri/card0 and re-login makes it work. So its the https://bugs.launchpad.net/bugs/2060268
