Xorg.0.log from hang using uxa

With uxa enabled, ubuntu jaunty boots to blue screen with movable cursor then hangs. Keyboard dead altogether. Mouse keys inactive. Top & bottom white panels were there but no response to anything. Only key that works is power off.

/etc/X11/xorg.conf:
Section "Device"
        Identifier "Configured Video Device"
        Driver "Intel"
        Option "AccelMethod" "uxa"
        Option "ModeDebug" "true"
        Option "FallbackDebug" "true"
EndSection

Xorg.0.log showing error from failing boot attached. (multi boot system, booted another image to mount & view failure logs)

This is ubuntu launchpad bug #330236.  The developer assigned to the bug Bryce Harrington asked me to report the bug here.

Anything else? Reproducable at will.

UXA is an intel driver specific fork of EXA.

ubuntu karmic koala with linix-image 2.6.30-1 running "uxa" O.K. on Intel i845.  Note I don't run any length of time, just an hour or so at a time.

So I'm marking this as fixed. Please reopen if you can still reproduce this with the new code. Thanks.

While "AccelMethod" "uxa" is working O.K,, do note that Option "Tiling" "false" is needed for example to properly display glxgears.  

Glxgears is a much maligned program which does produce fps (frames per second) somewhat erratically, however I don't have any indication it is doing anything unusual so the "gears" should at least display.

Thanks everyone for getting i845 running.  This note is from an IBM Thinkpad R31 which uses i830.  It's running O.K. however does have font character corruption problems since ubuntu jaunty beta; a problem has been written there.  Various characters will add pixels to the point of being unreadable.

Thanks again, Jerry
