If NO, then you should try fedora/vncserver grup/list first<br>
<br>
(2) What happens when you run as that user manually? e.g.<br>
- ssh falves@localhost (I find that su/sudo sometimes does weird<br>
things when it comes to limits, so login with ssh to be safe)<br>
- run whatever command that start vncserver<br>
<br>
(3) Have you set up special limits for that user on /etc/security/limits.conf?<br>
open files limit for normal user is usually 1024. However it's<br>
possible to use larger than that if root sets it to something greater,<br>
and run su/sudo. If that limit is reached, "normal" user usession (the<br>
ones not created by root su/sudo) would still be stuck at the old,<br>
smaller limit.<br>
<br>
The easiest way to check is to login as that user from ssh, and then<br>
run "ulimit -a". You didn't say where you run your ulimit commands<br>
from, so the results might be different.<br>
<br>
(4) Have you tried other remote GUI solutions?<br>
I use x2go with lxde-qt on my ubuntu trusty containers, works fine<br>
