what works:
- background wallpaper is shown correctly
- mouse seems to behave normally
what doesn't work:
- none of the launch bars is visible
- desktop icons flicker between their correct position and
a place just a bit to the left and down
- open windows flicker, moving down a bit each time
upon hitting the bottom monitor border, they stop moving but continue flickering
- right-click menu is placed correctly but briefly turns invisible while flicker occurs
- all flickering seems to occur in a one second interval
System:
- OS: Ubuntu 16.04 LTS (freshly installed on previously blank drive)
- Processor: Intel i7-6700K
- Graphics: NVidia GTX970
- Mainboard: MSI Z170A
The PC has no network connection right now, so i am unable to download/install packages...
If any other information is useful, please say so.
After some research I found out, that I fell victim to the following bug:
bugs.launchpad.net->llvm-toolchain-bug
Summarized: The version of the package libllvm3.8 which is distributed with Ubuntu 16.04 crashes on certain mixes of NVidia GPUs and Skylake CPUs. This is already fixed for later versions of the package.
Therefore a simple update as done below should fix the problem in 99% of cases.
sudo apt-get update
sudo apt-get dist-upgrade
