How to recognize a second screen in a minimal template

User Support General

Hello,

I’m interested in installing LibreOffice on a minimal Debian 12 template. However, I’ve encountered an issue where LibreOffice doesn’t detect the second screen.

When I utilize the standard Debian 12-XFce Template and run LibreOffice there, the second screen is recognized for LibreOffice Impress.

Now, I’m wondering which package might be missing in the minimal Debian template for Qubes to recognize the second screen.

Hi,

what’s the output of xrandr -q in both cases?

You are probably missing the xcvt package, which is used by the qubes.SetMonitorLayout qrexec service to set the monitors according to how they are set in dom0.

Thanks, that was the solution, it works.

Shouldn’t this be added by default to minimal templates?

I would say that it should be a dependency of qubes-gui-agent, since the monitor layout script depends on it to work properly.
