Hi I'm searching for a similar issue that's happening on my Kubuntu 12.10 system - resume from suspend fails. In my case there is a single line on the screen on failure - "drm nouveau .... " (sorry, it's only there for a short time) - looks like a line from a log.
This behaviour changed between KDE 4.9 releases and 4.10 - in 4.9 the system would fail to resume and there would be no way to get back to desktop without a restart (Ctrl + ALt + Del at that point triggers a restart - found that out through chance) or hard power off. In 4.10 the login manager reappears but the KDE session from last time is no longer available post login. I tried the instructions here: https://wiki.ubuntu.com/KernelTeam/SuspendResumeTesting ... but the system fails to resume as above and there are no test results. dmesg for a failed resume attached. $ uname -a Linux box 3.5.0-23-generic #35-Ubuntu SMP Thu Jan 24 13:05:29 UTC 2013 i686 i686 i686 GNU/Linux I'll try SSHing into the laptop to see what's running but aside from installing another kernel, not really sure how to debug this further so any pointers appreciated. Thanks! ** Attachment added: "resume_crash_dmesg.txt" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1066060/+attachment/3525074/+files/resume_crash_dmesg.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1066060 Title: [Lenovo B570e] Resume from suspend to blank screen To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1066060/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
