Description Monchi 2003-10-07 11:44:30 UTC 
Distribution: Slackware 9.1
Hardware Environment: Matrox Millenium II AMD Athlon 1.1 ghz 756MB ram
Software Environment: kernel console + XFree86 4.3
Problem Description: High resolution console gets garbled when X running at
higher resolution then the console

Steps to reproduce:
Compile kernel with Matroxfb and use video option 'matroxfb:vesa:0x193' when
booting.
Then start an X session, with mga driver in stead of fbdev driver, make sure the
X-session is running at a higher resolution then the console, and switch from
the X-session to the console.
Now run ls or simply clear screen.

This is all it takes for me to get garbled console results.
To go back to a normal console simple run X with the same resolution as the
console. ( maybe using the fbdev driver ).

I can reproduce this with 2.6.0-test9 and XFree86 4.2.1 on a G400. (Running
Debian woody with selected backports of packages from Debian unstable.)
