Dear Maintainer,

Xorg randomly _totally_ freeze : the cursor don't move and the interface is
blocked. It happens randomly when I use the computer. I don't have access to
the TTYs when this bug happens.

My only solution is to force the computer to shutdown (pressing 5 seconds the
start button).

This is the end of the Xorg's logs, I think that it would be usefull :


[  7217.766] [mi] EQ overflowing. The server is probably stuck in an infinite
loop.

Hi Dylan,

Dylan Belle <dylan.belle@gmail.com> (20/05/2012):

upgrade to latest xserver-xorg-core, xserver-xorg-input-synaptics
(available in testing/unstable), switching from X 1.11 to 1.12; and
please let us know whether that helps.

Likely one of those big bugs tackled in synaptics lately, the upgrade
should fix it all.

Mraw,
KiBi.

Me too I think. It freezes me a few minutes after being shown working as a
popup. The system still works but the keyboard does not respond, you can move
the mouse but the buttons does nothing.

Please file your own bug.

Cheers,
Julien

This bug still exists in debian wheezy with kernel 3.2.0-4-amd64 and
xserver-xorg-core 1.12

I'm attaching the backtrace generated by xorg

Dear Maintainer,

I just found this similar bug report, so I'll add that I am having the same
issue as described here.

I will add that I am generally able to ssh into my laptop and restart the
system. However, restarting KDM does not work, the screen continues to display
a frozen desktop.

I am using xorg 1:7.7+3~deb7u1 on Debian Wheezy/stable

I forgot the Xorg log from the actual crash:

No, you want to file your own separate bug.
