Apport has detected a possible GPU hang. Did your system recently lock up and/or require a hard reboot

I suggest you test your RAM using memtest86 from Grub.

What is the output of:

lsb_release -a; uname -a

Thanks

Hello,

I'm experiencing this too. It started just after upgrading kernel from 3.5.0-25 to 3.5.0-26.

Except this error reporting regarding apport-gpu-error-intel.py, I'm not experiencing anything weird.

Have you tried another desktop ession like XFCE, this won't require compositing and may ease your issue. If you install xfce4 package you will get a minimal xfce session installed, your Gnome apps will run without issue

Since issuing:
 sudo service apport restart
I don't see the problem anymore...

you have to reissue this after every reboot, until this bug get fixed.

[]s!

 sudo service apport restart
its
not helping..
this error is poping again and again
 sudo service apport restart this command
now its showing some erresor kind of structure a arectangle with half black and half in white

and now this mesage is comming again and again...and its bit annoying well i dont know what has happened

I suggest you report a bug. You may benefit from using the xorg edgers update ppa (not the bleeding edge)

I am experiencing the same problem. At one point I had three or four windows popping up telling me there was a problem.
"Apport has detected a possible GPU hangup? Did your system recently lock up or require a hard reboot?"
Most times I have clicked "No," but the last time my screen had frozen, so I clicked "Yes."
Occurred repeatedly for a few days on the Unity desktop. Switched to Gnome desktop environment, and the computer worked well for one evening. Resumed the error messages again after a day.
Something needs to be done to correct this.

I am facing same issue.

It started againg on my computer. And for the first time I have expecienced hard lockups.

My system has been locking up and requiring reboot to get going again. But the message saying internal error with apport-gpu-error-intel.py returns . I am loosing control of my windows and cannot do any useful work.

Not a solution, but I regain productivity changing my desktop to Xfce until this get fixed.
 sudo apt-get install xubuntu-desktop
Also I revert from lightdm to gdm as I could not start my Xfce session even after selecting it.
 sudo apt-get install gdm
 sudo dpkg-reconfigure gdm

btw reverting to an older kernel did not fix the problem, so maybe this bug must be chased elsewhere...

I did an update to kernel 3.8.4-030804-generic .
Result : only one error message a day and no hang-up. It works's for me.
see :
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1140716

How would I update kernel 3.8.4-030804-generic. Is there some sort of command line to use in the Terminal?

see : http://www.upubuntu.com/2013/03/install-linux-kernel-384-in-ubuntulinux.html

cd /tmp
wget http://dl.dropbox.com/u/47950494/upubuntu.com/kernel-3.8.4 -O kernel-3.8.4
chmod +x kernel-3.8.4
sudo sh kernel-3.8.4
sudo reboot

Thanks. I just did this. Did get the error message shortly after I rebooted, but that happened only once. If it stays to a once-a-day thing, like you mentioned, I can live with it. Hope this is corrected in Ubuntu 13.04.

You can disable apport.

gksudo gedit /etc/default/apport

Make the obvious change. Save the new file and close gedit. Reboot to test.
