Thank you for taking the time to report this bug and help ubuntu
improve. What probably happens "under the hood" is that when you resume,
the xserver either crashes or detects an error condition and exits. gdm
(the login manager) then starts up a new session and you are greeted
with the login window.

As you hopefully are aware of, the main purpose of bug reports is to
improve future releases of ubuntu (but grave issues may be fixed in an
update to an already released version). Therefore, we would like you to
check the updated versions of the driver, which you may get by adding
this PPA to your /etc/apt/sources.list:
https://launchpad.net/~ubuntu-x-swat/+archive/x-updates/ .

If the problem still exist in the newer driver from that PPA (currently the newest stable intel driver is 2.7.1), we would like to you to do the following procedure: (taken from http://intellinuxgraphics.org/how_to_report_bug.html and adopted to ubuntu)
0) Install the package xserver-xorg-video-intel-dbg to get the debugging tool intel_reg_dumper (`apt-get install xserver-xorg-video-intel-dbg`)
1) VT switch to a text console (with Ctrl+Alt+F1)
2) Run `sudo intel_reg_dumper >i_r_d-before.txt` to get a register dump
3) Suspend your machine with:
 a) `sudo -i` (to get a root shell)
 b) `echo mem > /sys/power/state`
4) On resume, before VT switching back to X (with Ctrl+Alt+F7):
 a) `exit` or Ctrl+D (to exit the root shell)
 b) Run `sudo intel_reg_dumper >i_r_d-after.txt` (to capture another register dump)
5) attach the files i_r_d-before.txt and i_r_d-after.txt to this bug report
(I tried to verify the procedure, but it turns out that my computer doesn't properly resume from hibernate)

In addition, we would like the file /var/log/Xorg.0.log.old from the
first time you log in after this happens. It should contain some
information about what went wrong.
