1 Hi all,
2
3 I've had this problem with various nvidia-drivers and never been able to
4 track it down. AFAIR it only happens during certain (one?) xscreensaver
5 hack. One of the 3d ones, but not necessarily one named GL*
6
7 When the hack starts, I see multiple tears every 1-2cm (10-15 in all),
8 each one offset to the right by the same amount. The colours look
9 inverted, or neon. The screen is "frozen".
10
11 I can ssh in and initiate a shutdown, although it doesn't complete; or I
12 can use the magic sysrq key. When the shutdown locks up, I can't use
13 sysrq.
14
15 Perhaps this is related, but when I run MoebiusGears with the settings
16 maxed I can get performance like this:
17 FPS: 220
18 Load: 100
19 Polys: 12000+
20
21 but sometimes on a different instance the FPS drops drastically to <90.
22 Don't know why.
23
24 I have:
25 nVidia Quadro FX 1600M (laptop)
26 2.6.32-tuxonice-r1
27 x11-drivers/nvidia-drivers-190.53-r1
28 x11-wm/compiz-0.8.4
29 x11-base/xorg-server-1.7.4

31 any ideas? thanks,
