Description Julien Cristau 2007-08-01 16:37:45 UTC
When trying xserver 1.3.99.0, i didn't rebuild the synaptics driver, so X failed to load the driver for the relevant InputDevice section in xorg.conf. So far so good. The problem then is that X crashes when switching back to the VT where it is running.
If I remove that spurious InputDevice it's fine.

I get this too with a freshly installed pair of xf86-input-keyboard and xf86-input-mouse.  Here's the debug backtrace:

Program received signal SIGSEGV, Segmentation fault.

Either the event type is not actually ProximityIn, or something is really, seriously broken.
Comment 5 Peter Hutterer 2008-01-28 14:34:00 UTC
aaron, julien: is this still an issue?
Comment 6 Aaron Plattner 2008-01-31 10:28:17 UTC
No, this seems to be okay with a server built from commit a125ce.
Comment 7 Peter Hutterer 2008-02-02 04:25:54 UTC
