Description Joao Carlos Mendes Luis 2025-09-20 20:05:11 UTC
Description of problem:
I was just moving my mouse, but I have a hard suspect for this.

Every time I turn VNC module in xorg.conf these crashes happen after some time.
Using VNC User Mode is too slow.

Here's the important parts of my xorg.conf

Section "ServerLayout"

Note: bug 2356978 was also reported by me.  Am I the only one seeing this problem?

It's very stressful to lose all your running desktop when X crashes.
