workaround: use an external monitor (HDMI and VGA worked, with some problems though, but that is unrelated [you can see some warning and backtraces] and didn't happen before) attached: whole dmesg, Xorg.0.log files after two consecutive suspend/resume cycles plus some testing with external monitors, and .diff files (from other session) showing messages logged only after suspend to RAM. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1034002 Title: Lenovo E525 screen black on resume To manage notifications about this bug go to: https://bugs.launchpad.net/dri/+bug/1034002/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
