[Problem]
On 845G X freezes a few minutes after log in, but does not freeze if left without logging in.

[Original report]
After a do-release-upgrade -d from jaunty to karmic beta, I am getting "lock ups".

If I don't log in and just leave gdm idling, the machine doesn't freeze. If I switch to a virtual console and use that, no freeze. I can ssh in just fine and do all kinds of stuff with no lock ups. But once I log in via gdm, I can go <strike>about 5-10 minutes</strike> EDIT 22 Oct 2009: anywhere from a few minutes to 12 hours or so until the machine:

EDIT 26 Oct 2009: Please see comments for update on how the freezes behave!

1) <strike>stops responding to all mouse/keyboard input</strike> EDIT 2 Oct 2009: In all freezes, the keyboard stops responding and mouse clicks do nothing. Recent freezes have left the mouse pointer movable, but some of the first freezes I saw left the mouse pointer immovable.
2) CapsLock will not toggle
3) <strike>sshing in doesn't work anymore</strike> EDIT 2 Oct 2009: This may not be the case. The freezes occurring over the last couple of days have left ssh still operating.
4) alt+sysrq+reisub will cause a reboot, and the screen usually blanks after the 'i' is put in to send SIGKILL to all processes.

I have the 82845G graphics chipset, and i915 is shown in the output of lsmod. As the problem only occurs when I'm in X, and as it doesn't matter whether I'm in GNOME or a failsafe xterm session, I suspect the graphics driver.

EDIT 22 Oct 2009: I'm working through the X freeze troubleshooting tips at https://wiki.ubuntu.com/X/Troubleshooting/Freeze and will provide more info as soon as possible.
