Hi Brian, I've tried to send a bugreport as you suggested using apport-cli and I was pointed to the existing bug #702090 which I subscribed. Though the fix for this bug isn't affecting my problem, you can close this report. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in ubuntu. https://bugs.launchpad.net/bugs/723624 Title: apport-gpu-error-intel.py keep crashing after login ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

Hi Bryce, other than apport windows popping up after login, no crash or lockup happens. I can work normally, only few graphical glitches when scrolling windows in gnome-terminal or chromium-browser. I'm definely affected by bug #702090, as you can see looking at the attached dmesg file but with no consequences. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in ubuntu. https://bugs.launchpad.net/bugs/723624 Title: apport-gpu-error-intel.py keep crashing after login ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

Hi all, I'm sorry to say that this bug is not fixed for me, apport keeps opening crash alerts about apport-gpu-error-intel.py. Beside that, I can't file a full report clicking on the button "Report this problem" (or similar message) since after a while apport fail to connect to the internet giving me this error: "apport: urlopen error [Errno 110] connection timeout" (probably because I'm behind a proxy server); I will report a bug for this). -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in ubuntu. https://bugs.launchpad.net/bugs/723624 Title: apport-gpu-error-intel.py keep crashing after login ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
