When I press suspend from menu. I only get black screen but I can hear disk running. *note: I've chosen encryption during installation - the whole disk as home * I've then install pm-utils and when I write sudo pm-suspsend computer freezes literally. I can't move mouse and when I try to wake it by pressing enter, it's not working.

I don't know how can I provide logs since then I'm forced to cold power off computer.

I can tell you hardware/software info:

hw: Acer Aspire v3 112p

CPU: Intel(R) Pentium(R) CPU N3540 @ 2.16GHz GPU is intel's integrated, lspci | grep VGA says: 00:02.0 VGA compatible controller: Intel Corporation ValleyView Gen7 (rev 0e)

  • Can you please explain me why would older kernel fix the problem. As I mentioned, I currently have 3.19.0-31-generic kernel, but with your suggestion I would actually get older kernel: The following NEW packages will be installed: linux-generic linux-generic-lts-trusty linux-headers-3.13.0-67 linux-headers-3.13.0-67-generic linux-headers-generic linux-image-3.13.0-67-generic linux-image-extra-3.13.0-67-generic linux-image-generic xserver-xorg-lts-trusty

I don't think this is a kernel issue because I tested several versions. I solved the suspend/resume issue by installing a proprietary video driver and blacklisting: nouveau

  • what proprietary video drivers did you install? I have Intel Corporation ValleyView Gen7 (rev 0e) video card. If you have intel video card too can you provide direct link for proprietary drivers pretty please? Or package name (even better).

There are 4 suspending modes i am aware off that you can select in the BIOS/UEFI (S1-S4).

Make sure you select the one you need.
