ad 1) When I boot the old kernel, the lines start to appear. They stay as long as I run the old kernel. When I boot the new kernel, they are there at the beginning and then slowly fade away and never come again. ad 2)3) Even if the cause was different, the reported behavior is the same. Anyway,

Yes, but thats a onetime thing. The bug somehow "burns" into the system, and it needs time to "heal". Now, when I start the machine, I don't have any issues. Thats why I called it weird, I've never seen something like this. See the link I posted in the original report: https://bugs.freedesktop.o

Thomas Diesenreiter: 1) Given the Proposed kernel didn't resolve the issue, this is not a duplicate of LP#1773520. Hence, to keep this relevant to upstream, one would want to periodically check for, and test the latest mainline kernel (now 4.18-rc4) as it is released. Could you please advise? 2)

Thomas Diesenreiter, a potential fix for your problem is in the Proposed repository. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. If you test this and it addresses the issue, this is likely a duplicate of LP#1773520, so feel free to mark it

Thomas Diesenreiter, to advise, given you have the hardware, it is best if you test reverting/adding of the potential regression commit, to confirm it is, in fact, the correct commit.

Hi there, I fear that I do not have the time to do such in-depth debugging atm. As I said, I used the latest kernel with my previous 17.10 install without this problem, and it occurred with the first kernel of the 18.04 release. I know that it would be easier for you to know the specific kernel

Thomas Diesenreiter, the next step is to fully commit bisect from 4.13.4 to 4.15.17, in order to identify the last good kernel commit, followed immediately by the first bad one. This will allow for a more expedited analysis of the root cause of your issue. Could you please do this following https:/
