problem w/ display


i've been running FC4 kernel 2.6.12-1456 for 6 months without any problem on EvoN610c. I just tried to installed ndiswrapper and bcmwl5 driver for wireless Motorola WN825G. everything seems fine until i reboot the machine. After reboot, the display is all blurry and i am unable to do anything. is there anyway to back out of this mess? Thanks.

Blurry?

ctrl-alt-F6 will take you out of the graphics window and back to a command line terminal. Actually fixing things may be a bit more complicated. I don't know much about the graphics setup. Do you have a backup of working config files?

What do ya mean by 'display is blurry' ? A lower resolution or corrupt graphics or ....?
If you could post the contents of /var/log/Xorg.0.log file, that could be a good start.

I should said: at the login, the display was black & white and the fonts are so big you can really see what is being displayed. after guessing by enter login name and passwd, the fonts on the display is so big and distorted i couldn't even try to reconfig the display. It looks like the graphic got corrupted. I'll try to retreive /var/log/Xorg.0.log to see what it is complaining. Thanks.

I can't get the entire /var/log/Xorg.0.log here. but here are some error message from /var/log:

Xorg.0.log file:
(WW) RADEON(0): open APM failed (/dev/apm_bios) (No such files or directory)
(WW) RADEON(0): Failed to detect secondary monitor, MergeFB/Clone mode disabled

messages file:
radeonfb: monitor 1 type LCD found
radeonfb: EDID probed
radeonfb: monitor 2 type no found
radeonfb: deteced LVDS panel size from BIOS 1024x768
radeonfb: BIOS provided deviders will be used
radeonfb: Dynamic Clock Power Management enabled
console: switch to corlour frame buffer device 128x48
console (0000:01:00.0): ATI Radeon LW


I found an /etc/X11/xorg.conf.backup and copy it to /etc/X11/xorg.conf but still having problem.

It will be useful if you can post the lines that contains the errors in the file /var/log/Xorg.0.log:

Type:

Code:
cat /var/log/Xorg.0.log | grep "(EE)"

There is no error in the /var/log/Xorg.0.log. Only warning messages I posted above. It seems the obvious error is in /var/log/messages file:

radeonfb: monitor 1 type LCD found
radeonfb: EDID probed
radeonfb: monitor 2 type no found
radeonfb: deteced LVDS panel size from BIOS 1024x768
radeonfb: BIOS provided deviders will be used
radeonfb: Dynamic Clock Power Management enabled
console: switch to corlour frame buffer device 128x48
console (0000:01:00.0): ATI Radeon LW

Why is it switch to corlour frame buffer device 128x48?

fbset -i

If you have an ATI Radeon graphics card, why don't you download drivers for you card from the ATI website and install them ? That could solve your problem besides, giving you a performance boost.
As it is clear from the part output of Xorg.0.log xorg is using radeonfb a frame buffer driver to drive your card and at a res of 128x48 ??&^%^*^
It's not too easy to figure out the correct mode lines for a given monitor and graphics card, so I guess you may have to experiment with different modelines or wait for some experto to respond on this and provide you with the modelines that would work for you.
Consider my suggestion about downloading drivers from ATI though.
Good luck
