Blinking 6600gt

[~L~]

Hi,

I recently upgraded my GPU to 6600GT 128 MB and it is in general working fine. This is after I updated my mobo bios (MSI k8t Neo) and tweaked xorg with SWcursor and norenderextention. I can run Doom3 with high setting at 1280x1024 - but I would settle with medium quality if it would work properly. My monitor (Samtron 71S) goes in to standby mode rather often. It only happens for a few secs and I can keep moving - and getting killed while it's off. This is rather annoying. This generally happens in a rather dark place like when entering the airlock - rather peacefull place where nothing much is happening. Same thing happens with quake 4. Notably enemy territory for instance seems to work well.

Same kind of blinking happens when I play a movie with mplayer (Xv). If I switch from window to fullscreen, the monitor sometimes goes blank like it would resync or something. This happens also if I fast forward quickly.

If I would use -vo gl2 it would show tearing. If I then launch nvidia-settings and enable opengl sync, mplayer would just freeze upon launching. Same happens with glxgears as I would get a whopping 0.23 fps out of it.

I don't know if these problems are related or not, but maybe...

Any help would be appreciated!

I'm on amd64 gentoo using the latest nvidia-kernel/glx and xorg7.0.
As powersupply seems to be a common problem: I'm using Nexus 400W NX-4090. http://www.nexustek.nl/nx4090.htm
According to Nvidia-settings gpu temperature is around 56C when idle (fanspeed usually at 20 %) and ~80 when running doom3 (fan at 100%).

Any ideas?

Ok. I'll do that when I change the monitor again.

I borrowed another LCD from work today: LG L1715S.
I haven't tested extensively yet, BUT no blinking in doom3 nor quake4 nor mplayer. If I enable opengl sync, I get 75 fps in glxgears as expected and mplayer do not crash, but plays video smoothly without tearing. I did not expect this...

Now the little one needs attention, so I'll do some more tests later.

EDIT: opengl sync is not related as it hangs also with the new monitor when running two kde sessions. monitor and projector. With single monitor it works.

mplayer bug report was taken from another yakuake terminal after the blinking.

quake report was taken from laptop via ssh when the display was constantly blinking.

I played the same position with the other monitor and it plays just fine.

I don't see anything unusual in your bug reports.

Does this also reproduce with the 'nv' X driver?

Thanks,
