Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem?
Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.16 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.

Ubuntu itself) until the video is done playing Status in linux package in Ubuntu: Incomplete Bug description: With some videos, it freezes VLC (windowed) and the whole computer. I can still hear the sound playing, and the computer operates normally again after the video is done playing. While it's frozen, I can't move the mouse, none of the hotkeys work (ctrl alt t, alt tab, etc), and none of the screen updates. Even the vol up/down keys on my Thinkpad don't do anything anymore. Once the video is done playing in VLC, everything is back to normal. It doesn't always happen with the same video, and it's not always at the same point in the video.
