Hello. I am running 0.3.6 compiz under Fedora Core 6 and nvidia 1.0-9631
binary driver. I have noticed that switching to console with ctrl-alt-f1
and then back to x with ctrl-alt-f7 locks up the system with a black
screen more or less (sometimes the lockup is complete, sometimes the
cursor moves and it is possible to switch back to console), A user on
nvnews forums suggest that disabling sync to vblank is a valid
workaround. Is this a compiz or a driver issue? Cheers.
This appears to be a Xorg/NVIDIA driver very annoying problem. You can fix
the vterm-X switching problem launching Compiz with the
"--indirect-rendering" option, but you wont be able to get the intermittent
performance fix you get setting '__GL_YIELD="NOTHING"' using indirect
rendering, as it says here
http://www.nvnews.net/vbulletin/showthread.php?t=77030 :
"If you are seeing intermittent performance problems such as hickups,
setting the __GL_YIELD environment variable to "NOTHING" in compiz's
environment may help"
so its not really a fix.
