Hi forum!
Sorry if this is the wrong spot, I'm posting here because the issue occurs on the most recent kernel, but not the LTS so I'm wondering if its a kernel issue...
I have a Lenovo ThinkPad X201t tablet computer, and its been running ArchLinux fine for 6 months now. However, within the last month I've noticed a problem where when I flip the screen around for tablet mode, Xorg crashes and drops me out in a terminal. This is the Xorg.0.log file.
I've never noticed the video/tabletmode ACPI event before, so I'm wondering if that is a new kernel feature or if it has been around for awhile? It occurs when a Windows computer would flip the screen automatically for tablet mode, so I get the feeling that it has something to do with that ACPI event but I haven't told acpid to do anything for that event. Any ideas? Let me know if you need more info, or if this fits better in another topic. I put it here again because I don't get this issue when I boot into Linux-LTS. Thanks!

What video driver do you have? Not sure if this is the issue, but in a recent
version of xf86-video-intel (2.20.9) performing xrandr stuff would crash the
sna driver. If that is the issue, I can give you a patch. (The new version
fixes this, but other stuff seems slow, so I would recommend 2.20.9 + patch).
*EDIT* you can test my theory with
xrandr --output LVDS1 --rotate invertedand see if it crashes on both kernels.

Thanks for the reply wes!
That is my driver, but I have the latest (2.20.12) installed and that command didn't crash it, so I believe xrandr is functioning ok... I'll try to upgrade to devel in the AUR and report back. I didn't think to check drivers... Thanks again!

Ok, so I've tried installing both -devel and -git and -devel pkgbuild didn't work for me (DRI problems like other posters, but removing --enable-dri just resulted in a different error... plus I'm worried I don't have the skill to run a -devel driver), and -git didn't fix the problem...

I've also tried installing lib32-drm (it was one of the solutions I saw...) and trying both sna and uxa to no avail.

Sorry it didn't help : ( It sounded so much like the I problem I had with my
X220T that I may have jumped to conclusions. I should have noticed that you
say your acpi handler *does nothing* at the moment... o.o
Anyhow, I'll let you know if I think of something else. Good luck.

So lets try an easier question...
Any tips where to go from here? I'd like to file a bug report, but I'm not sure where... Xorg? The driver? All of the above? Thanks...

I browsed your Xorg log and compared it with mine; you have a few errors that
I do not (the only ones I have are regarding the wacom tablet). Not sure if
this is of much consequence though.
Other thoughts: have you tried stopping acpid and then flipping the screen?
Also, do you have a DE running that might be listening for these events and
doing something? Maybe try startx with a barebones X setup, as per the wiki,
and then try it? If this does not help in narrowing things down, I guess I
would start with Xorg for a bug report. But I'm a linux noob, so you probably
shouldn't listen to me : ) Good luck.
