--- Comment #49 from Walter Nicholls <wal...@nic.gen.nz> ---
Sage advice, Thomas. This is odd. Did not survive a reboot. It runs the
script but doesn't set the setting. This might be getting a bit off topic, but
looks like it is time to further debug kde. I hope this formats ok and makes
sense.
kwin.sh contains (extra logging to prove it ran and did its job, or not, as is
the case)
#!/bin/sh
echo kwin.sh was run! >>/var/log/kde_debug_temp.log
echo In script Before KWIN_EXPLICIT_SYNC is: $KWIN_EXPLICIT_SYNC
>>/var/log/kde_debug_temp.log
export KWIN_EXPLICIT_SYNC=0
echo In script After KWIN_EXPLICIT_SYNC is: $KWIN_EXPLICIT_SYNC
>>/var/log/kde_debug_temp.log
If, from bash prompt, I run /home/walter/.config/plasma-workspace/env/kwin.sh
then as expected nothing is set; if I source
/home/walter/.config/plasma-workspace/env/kwin.sh then KWIN_EXPLICIT_SYNC is
set afterwars as expected. If I create newtest.sh containing only the line "
. kwin.sh " then KWIN_EXPLICIT_SYNC is set as expected (well ,for the
duration of the script anyway since it isn't itself sourced).
However if I modify startkde so that it contains logging
echo In startkde Before KWIN_EXPLICIT_SYNC is: $KWIN_EXPLICIT_SYNC
>>/var/log/kde_debug_temp.log
for prefix in `echo $scriptpath`; do
for file in "$prefix"/env/*.sh; do
(test -r "$file" && . "$file") || :
done
done
echo In startkde After KWIN_EXPLICIT_SYNC is: $KWIN_EXPLICIT_SYNC
>>/var/log/kde_debug_temp.log
Now reboot and look at the log file , it shows:
In startkde Before KWIN_EXPLICIT_SYNC is:
In script Before KWIN_EXPLICIT_SYNC is:
In script After KWIN_EXPLICIT_SYNC is: 0
In startkde After KWIN_EXPLICIT_SYNC is:
So my script is DEFINITELY executing, it is DEFINITELY setting the env var, but
that extra indirection in startkde - (test -r "$file" && . "$file") -
is enough to stop the setting from taking. So how the***^&#%#$($#%! was this
ever supposed to work???

- has something changed in Ubuntu 15.10? ]
