OK, having looked at one of the affected machines, I'm stumped. They're still running the xserver-xorg-video-intel-lts- utopic_2.99.914-1~exp1ubuntu4.3.1~trusty1_amd64.deb that I downloaded from Timo's page a couple of weeks ago. This is 14.04.2 on a Thinkpad X1 Carbon running 3.16.0-38.
The symptoms have returned -- widespread text corruption when resuming from suspend. What data, if any, should I collect to assist with 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/1432194 Title: Graphics unstable on Ubuntu 14.04 and 14.10 using Intel HD Graphics 5500 To manage notifications about this bug go to: https://bugs.launchpad.net/xserver-xorg-video-intel/+bug/1432194/+subscriptions _______________________________________________ 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
