[Bug 811640] Re: [gm45] GPU lockup render.IPEHR: 0x78080003

 

Hi Alexander, I notice in the trace that the code seems to be stuck in
code called by /usr/lib/libutouch-grail.so.1, which is the multitouch
code, and that you also have MatchIsTouchpad "on" specified in your
xorg.conf.

Are you able to reproduce this with current oneiric?  If so, please move
aside your xorg.conf and restart X, and see if you can reproduce the bug
then.

If not, then perhaps this is a multitouch related bug.  I've prepared a
PPA with the Ubuntu multitouch Xi2 components disabled, to help identify
whether the bug is in Ubuntu's MT code or in upstream's code; please
install this PPA and see if you can reproduce it.  Note that some of the
Ubuntu-added MT functionality won't be available with this PPA.
