[Kernel-packages] [Bug 1742867] Re: Screen blank, audio choppy, system locked
I tried 4.15 rc8, same result. Went back one rev from my GRUB to 4.13.0-21 and saw the same result. Looking at the dmesg and syslog output, there were a lot of references to the video system. Grabbed another video card, slightly older and put that in. The fan on the one that came out didn't feel like it was spinning as freely as I would assume. Card may have simply been overheating when playing YouTube. New card has almost 1 hour of YouTube playback now with no problems on 4.13.0-25. Odd that this issue happened right with the reboot to the newer kernel, but if that's all it was then job done. If I see any of the same behavior I will post again. ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1742867 Title: Screen blank, audio choppy, system locked Status in linux package in Ubuntu: Incomplete Bug description: While watching a YouTube video, screen went blank.

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.15 kernel[0]. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. Once testing of the upstream kernel is complete, please mark this bug as "Confirmed". Thanks in advance.
