I installed the most recent kernel today (3.5.6) and found that it worked with my stylus interface. However, rotating the screen now causes X to crash with the following error (from /var/log/Xorg.1.log):

Closing log file.
To rule out the possibility of another program being responsible for the crash, I ran startx from root, which has no .xinitrc file, and rotating the screen when running X as root also caused the same crash to happen. How can I fix this? Is there any other output you'd like me to provide?
The functionality of the tablet is relatively important for me. If the fix for this might take a while, what could I do in the meanwhile that would allow me to use my tablet normally again?

Don't know if this helps your situation or not.
Thanks @David Batson, but I actually never experienced any of those issues on my laptop before this one. I would like to try to find out exactly in which part of my system the bug lies, so I was wondering how I might go about doing that.
I have the same problem ... should we try a downgrade? I just updated my kernel to 3.5.6-1 (although before I updated, my touchpad and styus weren't working at all!)
I am also having this problem on an x201 tablet. I can confirm that this is actually acpid. Run $/etc/rc.d/acpid stop and it should not crash.
@confuseoldman, I run systemd and can confirm that stopping acpid.service causes the problem to stop. What can we do from here?
Well, apparently a bug report was made a couple weeks ago. I'm pretty shocked that I didn't find this in my search.
I'm running Arch on a X61T here. The link yucht posted on the 12th suggests that acpid is to blame. I tried adding 'exit 1' under video/tabletmode like so:
video/tabletmode) exit 1 ;;
But it didn't work. Curiously enough, running
rc.d stop acpid
before starting X stopped the segfaults upon rotation. A quick stop to the acpid manpage informed me that clients can...read all events directly from /var/run/acpid.socket (read: bypass the exit 1 in my /etc/acpi/handler.sh)?!
I now have the line
in /etc/conf.d/acpid. X still gets acpid events, but they get filtered through handler.sh first! No segfaults upon rotation, and no loss of functionality.

Just want to confirm that this fixed the issue on my X60!
In fact, it should probably be added to the X--- laptop pages on the wiki.
