I experienced the same issues regarding to the resolution and the 60 Hz stroboscope (and a non working mouse wheel for my PS/2 mouse, slow down Internet for PPPoE etc.) with current debianoid Linux. They drop old hardware, even if they claim not to do. Regarding to the monitor, I downgraded X and then I got back the wanted 1152x864@90Hz. The monitor can do better than 90 Hz, debianoid Linux for my setup can't anymore, but I guess there's no difference between 90 Hz and > 90 Hz. I'm using xserver-xorg-video-nv 1:2.1.17-3 + depending X packages, it's from Debian stable, while anything else should be from Debian testing. For Debian testing there's no nv driver anymore and the nouveau doesn't work on my machine, when using a kernel-rt. Perhaps a downgrade will solve the issue on your machine too. 60 Hz vertically is unhealthy. -- Ralf _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
