AFAIR it only happens during certain (one?) xscreensaver hack. One of the 3d ones, but not necessarily one named GL* When the hack starts, I see multiple tears every 1-2cm (10-15 in all), each one offset to the right by the same amount. The colours look inverted, or neon. The screen is "frozen". I can ssh in and initiate a shutdown, although it doesn't complete; or I can use the magic sysrq key. When the shutdown locks up, I can't use sysrq. Perhaps this is related, but when I run MoebiusGears with the settings maxed I can get performance like this: FPS: 220 Load: 100 Polys: 12000+ but sometimes on a different instance the FPS drops drastically to <90. Don't know why. I have: nVidia Quadro FX 1600M (laptop) 2.6.32-tuxonice-r1 x11-drivers/nvidia-drivers-190.53-r1 x11-wm/compiz-0.8.4 x11-base/xorg-server-1.7.4 any ideas? thanks, -- Iain Buchanan Harp not on that string. -- William Shakespeare, "Henry VI"
