beryl + nvidia + kde > black screen

paluszak

Hi,

I have installed beryl and I'm running it on my nvidia & KDE system. Everything's fine until I try to switch to a text terminal and then back to X, instead of flabbaergasting bery/KDE I can see only a black screen with (surprise) a mouse coursor. Did anybody have a similar problem?

I just saw this on the gentoo-wiki.

I'm having my own beryl issues too atm. wish I could help more.

I was getting a White Screen, which was caused by not loading the nvidia GLX, and after seeing something in my the /var/log/Xorg.0.log

paluszak, I've had the same problem. Turns out it's a bug in nvidia-drivers.
(See http://bugs.beryl-project.org/ticket/121 or http://bugs.beryl-project.org/ticket/46 for relevant entries in the beryl bugs DB)

What i did was change some settings in beryl-manager and it fixed the problem for me:

Under "Advanced Beryl Options" change "Composite Overlay Window" to "Don't Use COW"
Under "Beryl Settings Manager" in category "General Options" unselect the option "Sync to VBlank".

I don't know which of these two options did the trick.
