I could imagine the framebuffer is messed up...
Here i have been messing in various ways trying to get a native framebuffer resolution (from 800x600 to 1024x600 on a netbook with a 945GM Intel chipset), to no result.
After having restarted Xvesa several times without any symptoms first, after exiting Xorg console is black with several green rectangles, which change when some readable output is expected. Running apps which rely on framebuffer - e.g. mplayer or links2 - is resulting in rather psychedelic visual effects...
Wondering if there is a way to fix/reset the framebuffer, or even achieve to get plain basic text mode (without framebuffer).
