Hmm, I cannot see commit 8f207c2235397748d243f5af69c8da102ce37d0f
in git history, but commit
773875bfb6737982903c42d1ee88cf60af80089c seems to be of identical
contents. Maybe some commit --amend and/or push --force?

Anyway, 773875bfb6737982903c42d1ee88cf60af80089c seems to be in
today's daily Ubuntu build 1e771b84e47085ef9b6efea1321e7cb5a8b2c065.

Using that build I still get the warning on switching LVDS
mode (successful outcome), the patch obviously does not solve the
warning issue.

See attached log produced from running this script:

#!/bin/sh
cmd="xrandr --output LVDS1 --mode 800x600"
echo "*** calling $cmd" | sudo tee /dev/kmsg
$cmd
echo "*** returned from $cmd" | sudo tee /dev/kmsg

(I still leave the status as NEEDINFO, I'll provide more info about VGA
behaviour later)
