Yes, the problem started after an upgrade. From what I can see in the logs it seems that first the machine was upgraded from Ubuntu 17.10 to 18.04, apparently without problem. Then a few days later, the working kernel Ubuntu 4.13.0-43.48-generic 4.13.16 was replaced by 4.15.0-23.25-generic 4.15.18 which fails.
It will not be so easy to test another kernel, but I'll try. It will definitely be some days before I can report a result, I suspect. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1777245 Title: X freezes with kernel 4.15.0-23-generic (AMDGPU) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1777245/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
