Phew! That was easy!
Section "ServerLayout"
...
Option "GlxVisuals" "all"
EndSection
... and job done! Well, maybe it's too early to jump ?!
Thanks Michel!
A couple of questions.
- Does anybody knows whether this is a problem with nVidia cards as well ?
- What is the rationale behind hiding GLX visuals by default? Memory?
Speed?
- What was the version that introduced this change?
- Maybe I need to read first about FBconfigs. Any links?
Sorry about asking more questions, but I believe the answers will be
helpful not only to me
