[Bug 1160151] Re: X continuously freezing with /usr/share/apport/apport-gpu-error-intel.py error afterward
I've also just installed the 3.5.0-25 kernel with "sudo apt-get install linux-image-3.5.0-25-generic linux-headers-3.5.0-25-generic".

Why was a newer version not used? 2) Now that I've changed my kernel, will I be receiving automatic software updates OK? 3) What is the best way to keep up to date on the fix for this issue?

@Chris, My setup is very similar to markusj's, and I am still having the issue. Unless you can explain otherwise, I would have to agree that you've incorrectly marked this bug as "Fixed Released," when in fact it has not been fixed in Ubuntu 12.04. @Markusj, Would it be possible for you to verify that using Docky for a little while, and especially while hovering the mouse over it, can recreate the GPU freeze.

This sounds related to the bug I'm experiencing: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1160151 At the moment, I am not able to use Ubuntu on the affected machine because of the continuous freezing. The reason I decided to chime in here is because of the reference to the transparency issue: I am using Docky, which uses transparency effects, and I have found this bug to be easily reproducible when Docky is activated with a mouse hover-over. I'm seeing a lot of recent posts on the /usr/share/apport/apport-gpu- error-intel.py issue on various forums on the Internet, including AskUbuntu, Ubuntu Forums, Ubuntu Answers, etc. - most within the past week. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1159255 Title: GPU freeze possibly caused by transparency effects? sandybridge-m-gt2 GPU lockup IPEHR: 0x41e8 IPEHR: 0x0b140001 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1159255/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I did some further testing and found that the X GPU freeze most often occurs when the Docky app is being scrolled over. I remember seeing a similar post mentioning that they were experiencing a GPU lockup/freeze during transparency rendering (this would make sense with Docky). The affected computer is a work computer, and if I'm not able to resolve the issue within the next couple of days, my plan is to try to revert to a previous kernel, and if that is not possible, uninstall Ubuntu all together and install Fedora or Mint to see if their repos are less buggy. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1160151 Title: X continuously freezing with /usr/share/apport/apport-gpu-error- intel.py error afterward To manage notifications about this bug go to: https://bugs.launchpad.net/xserver-xorg-video-intel/+bug/1160151/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
