Description M. Veinot 2006-01-17 00:58:17 UTC
xorg segfaults on startup if the device specified in an evdev InputDevice  
section is not the right device.  
I recently moved my PC to a new room, and after reconnecting everything, X  
failed to start, segfaulting shortly after being started.  
It took me a while to figure out that my MX1000 was now event1, not event2  
where it used to be. Admittedly, I should have set up a udev rule to cause it  
to always appear at input/mx1000 which I have now done. Nevertheless, I feel  
that it should probably fail more gracefully in this situation, and possibly  
provide some insight into what it thinks is wrong.

I found the same thing, which is a total PITA since I have a laptop. Theres a
line in evdev.c (somewhere near 691), that goes: 

xf86Msg(X_ERROR, "Unable to open evdev device \"%s\".\n", device);

I found removing the xfree(pEvdev);  line fixes that... Its a gross hack, but
perhaps its a start for finding the real cause.

This bug is no longer an issue with the new evdev driver in the modular CVS tree.

Reassign to the new evdev maintainer.
