[arch-dev-public] Problem with X?

I've got this weird problem that I think is caused by X. I've been following testing for a while now (so I have gnome, db, and heimdal). Every so often, and apparently randomly, X will stop taking any input except for mouse movement. But the mouse movement doesn't even trigger the focus follows mouse. The panel will still update and so will windows, but my input just totally doesn't work. The only thing that I can do to fix it seems to be sshing in and killing X. I run xfce4 so it might be the gnome/gtk updates that aren't working well with it... Has anyone heard anything about problems with X or is it just me? Jason
