Description Sven Arvidsson 2009-09-11 04:33:52 UTC

The commit below broke mouse cursor in Doom 3 and a lot of other popular games.

I get an initial cursor, but it quickly disappears offscreen as soon as it is moved, leaving the game unplayable.

fe7693c94a396b9d17bb66a000178750a432ce3a is first bad commit

    Make DGA optional
    
    As DGA is optional in xserver, we should check this too instead
    of always trying to init DGA.
    
    Found when update xserver to 6fffcd5825454a7fe58ffbcfb219f007cf38e731,
    but not update xf86dgaproto, which caused X fails to start.

Comment 1 Sven Arvidsson 2009-09-12 07:21:38 UTC

So I guess basically XFreeXDGA actually needs to be #defined somewhere, or else xf86-video-intel is built without DGA?

Comment 2 Sven Arvidsson 2009-09-12 07:58:45 UTC

Apologies! The first bisect was wrong, this should be it:

    intel: use _mesa_meta_clear(), it's a bit faster

Please ignore, wrong bug report.

XFreeXDGA is obviously already set xorg-server.h, duh!

It's "if (!pI830->use_drm_mode)" which is causing the problem. 

I also noticed the following errors logged by the game:
Fatal X Error:
  Major opcode of failed request: 130
  Minor opcode of failed request: 2
  Serial number of failed request: 148
XF86DGANoDirectVideoMode
Fatal X Error:
  Major opcode of failed request: 130
  Minor opcode of failed request: 2
  Serial number of failed request: 1497
XF86DGANoDirectVideoMode

Sven, thanks for the report. So what's the actual bisect result?

I agree this is probably the same as bug#23858
