The same here. Resume after suspend used to work well until a software update:
Start-Date: 2015-07-01 01:24:16 Commandline: aptdaemon role='role-commit-packages' sender=':1.83' Upgrade: xserver-xorg-video-intel-lts-utopic:amd64 (2.99.914-1~exp1ubuntu4.2~trusty1, 2.99.914-1~exp1ubuntu4.3~trusty1), unattended-upgrades:amd64 (0.82.1ubuntu2.2, 0.82.1ubuntu2.3) End-Date: 2015-07-01 01:24:19 Since then, resume after suspend does not work well and the windows are not drawn properly. The details of the laptop are: ThinkPad T550 i5-5200U Ubuntu 14.04 Gnome-fallback (I think is the same as Gnome-shell?) . Metacity in any case. I tried to use lightgdm and gdm, but do not solve the problem. Using the proposed 2:2.99.914-1~exp1ubuntu4.5~trusty1 update do not fix the problem either. ( #134 of the bug #1432194 https://bugs.launchpad.net /xserver-xorg-video-intel/+bug/1432194 ). For the moment the only workaround is to switch from SNA to UXA ( comment #28 of the bug #1432194 ), with a lack of performance. ** Attachment added: "Screenshot of the bug" https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1452318/+attachment/4426568/+files/with_2%3A2.99.914-1%7Eexp1ubuntu4.5%7Etrusty1.png -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1452318 Title: Faulty behavior when resuming from suspend To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1452318/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
