Hi Miguel,
The reason I'm asking is because I can't reproduce any problems on GDM,
with any software that uses GLX or other libraries, after adding the
workaround.
But I noticed something looking again at the system info you forwarded,
the only user in the "video" group is sddm:
video:x:44:sddm
I verified yesterday that even on GDM both the DM-manager user (in my
case Debian-gdm) AND my user MUST be in the video group, otherwise the
problem occurs.
Could you please try to add your user to the video group and see if that
helps?
And it seems that works like a charm! It seems KDE only needs sddm and
your user to be included in the video group. No more panics or black
screens.
Good shot!
We are still discussing and investigating that. It is not a new upstream
requirement but a fix to the device nodes permissions that we are trying
out, but it seems to be causing way too much grief. Please see this
message by Andreas [1] for more details about the background.
Kind regards,

I am sorry, I don't see the message from Andreas your are referring to.
Thanks!
