I have laptop lenovo g40-45 with ubuntu 16.04 Gnome installed.

The problem is that after suspend, i just got blank screen and cannot do anything but force-shutdown from power button.

I had ubuntu 14.04 unity installed before, it suspends and resumed perfectly.

My question: is it hardware problem or a gnome problem?

  • We could try a workaround, with a keyboard shortcut. Would that interest you? Would save you a restart if it works.

  • From a terminal, what happens if you run sudo pm-suspend ? Does it suspend and resume properly?

  • Please enter this in terminal : sudo apt-get install pm-utils then restart your computer and try again.

From Ubuntu 16.04, Ubuntu and ATI have collaborated to develop new open source graphics drivers to replace fglrx which existed on 14.04.

It is not a hardware problem since you can perform suspend and resume operations perfectly.

It appears like a graphics driver problem.

You can file a bug report or wait till subsequent updates to the driver fixes this.

It's related to both our BIOS and Kernel version. Normally a combo of Lenovo BIOS version older than 2014 and Linux kernel above 3.16 breaks suspend. There is a bug open on it: bug 1528735
