Public bug reported:
I have a Dell Inspiron 1525 with the i810 video chipset.
I have also disabled Xinerama with the xorg.conf option:
Section ServerFlags
Option "xinerama" "no"
EndSection
Here's what I have to do to reproduce the bug:
Start the RuneScape Java applet. Go to video settings on main screen and go to
HD Fullscreen on the highest resolution (in my case 1440x900). A message will
pop up saying "Video settings changed, do you want to keep these settings?" and
a 10 second countdown. For me, the countdown freezes at 9 and I suddenly get a
bunch of blue on the lower third of the X window followed by an infinite loop
of X crashes.
This is particularly odd because it seems to work just fine on other
resolutions.
Here's an excerpt from my dmesg after this event (which is very hard to get
because X is crashing so much that most of the time it won't register a
Ctrl+Alt+F1 call):

I'm not sure this is the correct package to report for the bug (after
all it's a problem with libdri.so). Then again, I'm not sure if it can
be reproduced on other video hardware.
Can anybody else confirm this?
