Description Andreas Stenglein 2005-09-18 04:57:23 UTC

After enabling exa (Option "AccelMethod" "exa" in Device Section) the mouse
doesnt work in quake3 and ut2003_demo:
moving the mouse in any direction results in the cursor going to the lower right
corner of the screen and stick there.

Commenting out the line solves the issue.

This happens with todays CVS HEAD on a Radeon 7500 card.

DGA is known to be unsupported with EXA at this time for the radeon driver.

        (RADEONScreenInit):
        bugzilla #4494 (https://bugs.freedesktop.org/show_bug.cgi?id=4494)
        Call RADEONDGAInit() even if EXA is enabled; the problematic DGA
        acceleration hooks are already disabled in that case.
  
        This fixes DGA issues such as DGA mouse (typically used by games in
        fullscreen mode) not working.
  
        Fix suggested by Eric Anholt.
