This is wiered. I tried, with my PC booted on kernel: 4.3.0-040300rc2-generic, to launch this command in terminal:
sudo sh -c "sync && echo 1 > /sys/power/pm_trace && pm-suspend" as it says here: https://wiki.ubuntu.com/DebuggingKernelSuspend#A.22resume-trace.22_debugging_procedure_for_finding_buggy_drivers My PC looks like suspending: it turnes off and the power LED slowly flashes when in the suspended state (at least it looks like suspended). I wait a bit, 2-3 minutes, press the power, button, I see the HD LED flashing, but my PC returns from suspension without entering the lock screen, I find it resumed just as I left it as nothing happened, no blue screen no freeze, nothing. I am attaching the dmesg file obtained immediatly after resuming from suspension. As I did this twice I have two dmesg files to attach, one for each time I suspended. ** Attachment added: "dmesg-first-time" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1490143/+attachment/4476581/+files/dmesg.txt -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1490143 Title: When resuming after suspension desktop is freezed Status in linux package in Ubuntu: Incomplete Bug description: I suspended my PC for like about 1,5 - 2 hours and when I resumed the desktop had a black background, you could see the launcher bat you were unable to do anything it was freezed. This is my hardware: https://gist.github.com/anonymous/3203c7c5a43a509c0f22. I am attaching the screen-shots of my desktop after resuming, also in terminal (CTRL+ALT+F1) it looked rather garbled.
