Description Matt Domsch 2002-11-22 14:24:43 EST
Description of Problem:
Installed XFree86-4.2.99.2-0.20021110.3 from Rawhide on a RHL8.0 system (Dell 
Latitude C400).  I rebuilt i830.o from XFree86 CVS source 11/20/2002 and 
copied it into place.  Everything works fine if running on the LCD screen.  It 
fails when starting to play a DVD using Ogle when docked and connected to an 
external monitor.  The error is:

Running kernel is 2.4.18-18.8.0 plus i830.o DRM from CVS.
Comment 3 Mike A. Harris 2002-11-29 04:53:31 EST
Can you try using the following option to see what happens:

        Option  "XaaNoSolidFillRect"

Does it change anything?
Comment 4 Matt Domsch 2002-12-02 11:00:31 EST
Yes, that fixes it, thanks!
Should this be closed, or reported somehow?
Comment 5 Matt Domsch 2002-12-02 11:36:03 EST
I spoke too soon.
The problem happens at resolution 1280x1024x24bit, with or without
XaaNoSolidFillRect.

The problem does not happen at resolution 1024x768x24bit, with or without
XaaNoSolidFillRect.

(aside, running at 1024x768 with a virtual size of 1280x1024 and starting a
movie in Ogle, then pan the screen to put the movie window into view and the
system rebooted itself.  I hate virtual desktops so I won't worry about it...)

Resolving as dupe, please use the dupe to track further progress, and submit
