Chris, Thanks. I attempted to run the apport command from an alternate terminal during my last lockup, but was denied access due to a lack of an http referrer. Not sure if this would work better if I were to try this from home, rather than from work..
I have a somewhat less-than-satisfactory workaround for the black screen: I can drop to a terminal, and run "unity --replace" twice. This trashes access to ssh-agent for new shells, and re-arranges the desktop, but, at least it leaves my currently running processes alone. I'm actually running 12.04 LTS rather than 12.10 lsb_release -a LSB Version: core-2.0-amd64:core-2.0-noarch:core-3.0-amd64:core-3.0-noarch:core-3.1-amd64:core-3.1-noarch:core-3.2-amd64:core-3.2-noarch:core-4.0-amd64:core-4.0-noarch Distributor ID: Ubuntu Description: Ubuntu 12.04.2 LTS Release: 12.04 Codename: precise Thanks, Brad On Sat, Jul 13, 2013 at 1:34 AM, Chris Wilson <[email protected]>wrote: > Please apt-get install xdiagnose and run apport-collect 1200807 after > the issue occurs so that I can check your system for obvious errors. > > ** Changed in: xserver-xorg-video-intel (Ubuntu) > Status: New => Incomplete > > -- > You received this bug notification because you are subscribed to the bug > report. > https://bugs.launchpad.net/bugs/1200807 > > Title: > Frequent black screen with graphics cursor upon returning from > screenlock > > Status in “xserver-xorg-video-intel” package in Ubuntu: > Incomplete > > Bug description: > Occurs frequently, Since installing package updates last week. > > Hardware: Lenovo X220 I7 > Have tried unity --reset > Have tried resetting compiz settings. > > Have recursively removed .compiz* .gconf* .config/dconf/ > .config/compiz* > > Bug 966744 looks very similar. > > Thanks! > > Brad > > To manage notifications about this bug go to: > > https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1200807/+subscriptions > -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1200807 Title: [12.10] Frequent black screen with graphics cursor upon returning from screenlock Status in “xserver-xorg-video-intel” package in Ubuntu: Fix Released Bug description: Occurs frequently, Since installing package updates last week.
