 Posted: Thu Apr 03, 2008 2:47 pm Post subject: Switching resolutions causing blank screen |
 |
|
I just installed a fresh Gentoo installation and I am having some resolution problems. I am running Xorg + Gnome on a 30" widescreen monitor with the proprietary nVidia drivers. For the most part everything is working fine as I can run at 2650x1600@60Hz, 3D works, etc. The problem I am having is when I use alt+ctrl to switch to a terminal. The screen goes blank and most of the time I cannot switch back to graphical mode. The same behavior also happened when I log out and when I try to resume from screensaver. Again, it only happens intermittently. I am using uvesafb as my framebuffer device and it is set to 1600x1200-16 (which was supported by my video bios). Any ideas?

I had to disable the resolution part of my kernel video=... line in grub. I basically have a 800x600 terminal on a 2560x1600 screen, but at least it is not hanging up. I'm still hoping there is a solution out there somewhere.

Bumping as I still haven't figured out a solution to the problem.

No ideas but I have the same issue running uvesafb at 1400x1050 when switching from xorg in 1680x1050 on nvidia.
I get some error messages from uvesafb when alt+ctrl to switch to VT:

Just for kicks I switched to the 'nv' driver from the kernel blob from nVidia. I couldn't run at the native 2560x1600 resolution in Gnome, but when i switched to 1600x1200 terminals I had no problems. It may be an nVidia driver + uvesafb issue.
