I first tested without drm.debug set. FWIW, I noticed the cursor is briefly displayed when playback starts and stops, but definitely not when I see the stuttering. I experimented with turning on mythtv's "hide cursor" option. Didn't help, I still see stuttering. So I rebooted with debug enabled and log_buf_len=512K. The output is in dmesg4.txt I started playback after about 120 seconds from boot time, with "hide cursor" disabled. Same stuttering. Stopped playback. Some time after 190 seconds, I turned on the "hide cursor" option and even unplugged the USB optical mouse I use when doing maintenance (never been fond of touchpads). Then started playback. I still see stuttering. You mentioned looking at the ddx debug log. Is that the same as the "xorg debug log (xf86-video-intel compiled with --enable-debug=full)" mentioned in comment #5? If so, would it be sufficient to download and compile the deb-src package that matches the binary version currently installed on the laptop? It is called xserver-xorg-video-intel and is at version 2:2.99.917+git20171229-1. That version contains the most recent tag albeit from 4 years ago, and apparently has some patches from last December. Guess I'm worried compiling from master could introduce ABI incompatibilities with other xorg packages. Also, would I be correct in assuming the xorg/ddx debug log will go to /var/log/Xorg.0.log?</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
