OK, so I tested the removal of the items requested (still with BIOS set to fixed). After

I tried running the video in totem. Same problem as before - random lags/stutters/freezes, usually < 1 second, but a few that were longer (longest was about 2.5 seconds this time around).

So then I tried

> sudo apt remove i965-va-driver

then ran the video in totem. If anything, the problem became worse - the lags were more prevalent, and the longest was > 3 seconds.

So I went back to mpv and ran the video there. There were minor stutters (not long enough to call them lags - I would estimate they were mostly < 0.25 seconds) scattered through the video at random, but none long enough to really cause me to say "this is unwatchable". However, I did notice increased CPU usage - the system became noticably warmer to the touch while the video was playing, and the fan kicked on high to cool it (previous instances I didn't notice the fan kicking on - perhaps it did, and I just didn't notice it. I have copied below the terminal output for mpv, in case any of it is relevant (I didn't notice much different than the past - just a warning about a decoder not supporting hardware). I can re-run and see if I can catch a lag long enough for me to start dmesg if you like. Just let me know what would help you most from this point.

Exiting... (End of file)

Also, should I reinstall the i965 and mesa drivers, or leave them uninstalled for further testing? (I will definitely leave them uninstalled until I hear otherwise, or for a day or so at any rate...)
