Public bug reported: I'm trying to enable a reliable hibernate/resume cycle on a intel haswell cpu/gpu system with ubuntu 13.10 +xfce. Until now I've failed, because I get three possible outcomes, when resuming (without seeing any pattern). In all cases pm reports, that 'Image restored successfully'; visible on tty1. Resulting system states after resume: i) resume just works fine, everything is o.k ii) X freezes, screen is completely black, mostly no reaction to key strokes (i.e. can't change to ttyX), but ssh is possible iii) like ii) but network is not reachable (I'd say a complete freeze)
>From situation ii) I got a dmesg (attached), which makes me think, that intel gpu driver is to blame. ** Affects: xserver-xorg-video-intel (Ubuntu) Importance: Undecided Status: New ** Attachment added: "dmesg_after_freeze.txt" https://bugs.launchpad.net/bugs/1250498/+attachment/3906546/+files/dmesg_after_freeze.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1250498 Title: haswell, X may freeze after resume To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1250498/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
