[Bug 393031] Re: [i855] Resolution change breaks graphics in Intel 855GM

 

Testing with Karmic Alpha 4

Boots up in dock (port replicator) with laptop screen blinking between green, blue 
and red. Screen is connected to VGA through dock. Loading bar is shown, but with 
strange artifacts. X loads with the wrong (1024x768) resolution instead of the right 
(1600x1200) and laptop screen continues to flash the colors. 

I disable the laptop screen with the display tool. After that, resolution change
to 1600x1200 works fine. Trying to move the display to the laptop screen with
the display applet results in the same color madness. Waiting 15 seconds makes 
the applet switch back to the external monitor. 

man intel shows xf86-video-intel 2.8.0. Shouldn't this be xorg?

Booting with the screen disconnected results in the color madness during boot. 
X doesnt come up and the other tty's are inaccessible. Tried twice, waited for 
~10 minues. Then plugged the laptop into the port replicator with the screen and
works like described before (color madness on laptop screen, loads on external 
with artifacts). Est loading time 3-4 minutes. 

This behavior is nothing like jaunty or alpha2 of karmic. Attached is the Xorg 
log file for the successful boot. 

Why did the manpage say xf86 at the bottom. The rest of the man page talks 
about XOrg.
