Code, bahaviour, defaults, interaction with other packages, ... - whatever. I tried with Ubuntu18.04 and Manjaro (Arch) and downgraded the kernel from 4.15 to 4.08 (Ubuntu) and from 4.19 to 4.4 (Manjaro) and the problem is gone. In both cases I don't do anything else explicitely. I install the kernel and reboot. Entering the desktop shows freezing (gpu hang) with actual kernel or normal behavior with older versions. My investigation showed that 4.9 or higher has my problem. Just for compleetness here: my BIOS is up to date and 'intel-microcode' seems to be the latest as well. If anybody want's to have more information I am happy to support, otherwise I have my ear close to some forums and wait..</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
