Description Maciej Cencora 2009-09-19 02:40:26 UTC

UT2004 demo windowed mode:
cursor is working okay while in menu and during the game until the menu is invoked - after resuming the game the mouse movements seems to cause some random cursor movement events.

UT2004 demo fullscreen mode:
no cursor available.

Painkiller:Overdose under wine:
cursor available while in menu, unavailable during gameplay.

Penumbra Overture windowed mode:
cursor available while in menu, unavailable during gameplay.

Penumbra Overture fullscreen mode:
no cursor available.

Cursor in all these games is working fine when system is run without KMS.

First of all, any X related bug report needs at least the full log file.

Define 'cursor unavailable' - do you mean the cursor is not visible, or something else?

Does

    xdpyinfo|grep DGA

give any hits?

Xorg.log

xdpyinfo | grep DGA returns:
XFree86-DGA

Yes, when saying cursor is unavailable I meant cursor is not visible.

init dga on kms

The kms path never inits DGA.  Maybe something like this untested patch?

However, as Keith pointed out on the xorg-devel:
http://lists.freedesktop.org/archives/xorg-devel/2009-September/002113.html
using DGA for graphics (not cursor or modesetting) won't work in this case.
