Output of WINEDEBUG=+x11drv,+x11settings wine notepad.exe &> wine.log before
and after registory import of "UseXRandR"="N"

I have a multi-seat setup.

Wine works fine on seat0 but not on seat1. On seat1 whatever program I try to
open it just kind of hands and never shows any window.

This seemed to start with wine version 6 so until recently I just stuck with 5
but I'm now trying to sort this.

With the help of AI, I discovered that this is probably an issue with the use
of randr. Specifically, if I import this into my registry then I can get Wine
to work with seat1 too, though this does lead to some other issues (I don't
think Wine can then change the resolution so I have to do it manually before
starting any games).

REGEDIT4

[HKEY_CURRENT_USER\Software\Wine\X11 Driver]
"UseXRandR"="N"

I am attaching the output of this before and after adding the above line:

WINEDEBUG=+x11drv,+x11settings wine notepad.exe &> wine.log

Many thanks for your help!
