Ubuntu novice here. :)
So far very happy and pleased with Ubuntu, but have a strange issue. I have re-installed Ubuntu 16.04 from scratch two times now, but problem keeps recurring:
When my computer has been in screenlock I can log in and active windows can be used with both mouse and keyboard but the Launcher and the top menu bar are both non-responding. Using Alt+F2 works, etc, but I cannot press or start any programs on the Launcher and also no reactions from pressing anything in the top menu bar.
A restart/reboot immediately solves the problem every time but is of course very inconvenient.
Below are some details for my system. I would appreciate any input or suggestions. :)
