After upgrading to the newest Xorg, I can't plug or unplug my AC
adapter without triggering a segfault:
Segmentation fault: 11 at address 0x802d873f0

Also, X seems to freeze up until I move the mouse around a bit, like
it's getting hung. Very strange. I've tried messing around with HAL
a bit thinking that might be the problem, but to no avail. It appears
that HAL is now mandatory when using the Synaptics driver, and I
wonder why.
As always, any tips on debugging are appreciated...

Of course Warren! Thanks so much!
I was aware of your page, but had not had reason to read through it
entirely. This is the particular snippet that that characterized what
I was experiencing:
"Other times, particularly if hald is running, typed characters don’t
show up on the screen until the mouse is moved, and mouse movement
itself is jerky and doesn’t react smoothly."
I added:
Option "AutoAddDevices" "Off"
to my ServerLayout section, and that particular problem is solved.
Unfortunately the segfault is still occurring when plugging/unplugging
the AC adapter. I'll try to dig into this if I can.
One more thing to add: I can't start up my GLX screensaver, but I'll
start another thread about that:
$ xlock -mode biof
X Error of failed request: BadWindow (invalid Window parameter)
Major opcode of failed request: 137 (NV-GLX)
Minor opcode of failed request: 4 ()
Resource id in failed request: 0x2000006
Serial number of failed request: 190
Current serial number in output stream: 190

The problem with X.org segfault-ing boiled down to an issue with the X
Server calling vfscanf(3) in a funky way, which happened to be fixed
by r234836.
Also, the issue with NV-GLX has been fixed by some update (maybe the
new NVIDIA driver?), so that's cool.
I continue to battle with my trackpad, as after exiting X the new
synaptic driver doesn't seem to let go of /dev/psm0 -- I'll start a
new thread for that after further diagnosis.
