[Nouveau] nv50 mouse cursor disappears hourly

[Brian DeRocher]

I compiled linux-2.6 from git.  I think my last pull/merge? is this one (git show)

    drm/nv50: Improve PGRAPH interrupt handling.

I also compiled nouveau-drm_2.4.18-1_amd64.deb and nouveau_drv.so that day and installed them to a Debian system.

I'm using KDE 4.3.  The mouse cursor disappears, but menu items that glow when the mouse is over them will still glow when the mouse is over them.  I can click on stuff and menus pop up or actions occur as normal.  I can logout, but i am not returned to the KDM menu.  I can't switch to a virtual terminal.  I must do a hard reboot.  I haven't tried that SysReq thing.

Next time it happens, i'll check /var/log/

I have compositing turned off according to KDE system-settings / Desktop.  In fact all desktop effects are disabled.

Here's my xorg.conf
