[Bug 589548] [NEW] Ubuntu Lucid Spontaneously Freezes or Logs out

Mon Jun 7 15:51:01 UTC 2010

You have been subscribed to a public bug:

First, I am not sure if Gnome is really the problem. However, because Ubuntu's byzantine bug reporting system does not give one the option of reporting a bug without first declaring which package is at fault, I had to pick at something. I chose Gnome because it was the most general package I could think of.

The problem is that Ubuntu/Gnome routintely and spontaneously freezes or
logs me out. The frequency is something around once per hour, or once
per two hours. It seems to be more frequent on battery power, but there
is a certain amount of randomness to the time between the problem
occuring, so it is hard to be sure.

When spontaneously logging me out, the screen will suddenly go black,
and then return to the log in screen after about 30 seconds to a minute.

When freezing, the mouse will still be able to move, but I can not get
any response by clicking on anything on screen. Trying to shut down X by
pressing [ctrl]+[alt]+[backspace] also does not work. When the laptop
freezes this way, the only way to get back to operation is to force a
shut down by holding the power switch on the laptop.

I have not been able to deduce any cause. For example, the last three times it crashed, this is what I was doing:
* Moving an event in Google Calendar within FireFox.
* Opening Gedit
* Midway through a system update using the Update Manager

I can not see a commonality in the actions before the problem occurs, so
I assume it is something general about graphics or system operation that
is always in effect, and that the problem is essentially random.

I have a Panasonic CF-Y2 "Let's Note" laptop computer.

The video chipset is known to be problematic:
VGA compatible controller: Intel Corporation 82852/855GM Integrated Graphics Device

However, I do not get the black screen on boot that others report, so I
can not be sure that this is the source of the problem.

In any case, with regards to my video settings, I do not have an
/etc/X11/xorg.conf file, and I use the intel driver at
http://ppa.launchpad.net/glasen/intel-driver/ubuntu

I looked in /ver/log to see which files had been updated prior to the
last crash, and I didn't see much, but I thought these might be
relevant.

Error in /var/log/Xorg.0.log
(EE) intel(0): Disabling acceleration.
