Title:
matroxfb causes corruption in both virtual consoles and xorg
Status in linux package in Ubuntu:
Won't Fix
Bug description:
Loading matroxfb causes corruption in virtual consoles (ctrl+f1 up to
ctrl+f6). Framebuffer is loaded with settings 800x600x32bpp (mode 0x115) as
reported by dmesg, fbcon is loaded but characters in virtual consoles are
unreadable, when I type something i just see some random pixels (located far
away from the expected prompt), and also unreadable is the output of each
command I launch. The only way to read what is shown on the screen is switching
to xorg (ctrl+f7), then switching back to the virtual console, then the text is
fixed; but, unfortunately, typing new characters brings the same result as
before.
Also, the framebuffer is needed in order to enable tv-out on my matrox g550
via libdirectfb used by mplayer (device `-vo dfbmga'). Well, when I run
`mplayer -vo dfbmga myfile.ext' then I can see the clip on my tv but the whole
desktop gets corrupted showing random colors. Everything turns back to normal
activity when I quit mplayer. This feature worked until a couple of weeks ago,
in my good old hardy heron installation, when I watched movies on my tv while
using desktop apps. (I must admit, I actually don't know if this bug is due to
matroxfb or libdirectfb or mplayer).
Further, loading matroxfb makes gdm unable to show the login screen at
1280x1024 (it was able when no framebuffer was loaded). I tried this without
xorg.conf file and gdm caused the monitor to go blank, showing an `unsupported
frequency' alert. Then I created a xorg.conf file and set two resolutions in
the same `modelines' statement: 1280x960 and 1280x1024; now gdm shows login at
1280x960 (the screen is still at 1280x1024 anyway, so I have to move my mouse
in order to see it all), while xorg, which is loaded after login, is able to
set 1280x1024.
I report this here and I will soon check a newer kernel package.
