Comment 4 for bug 1902343

Sorry, I seem to have misread the patch when checking if this was syncable. This should indeed be a merge! If no one else picks it up, I can convert this issue to a merge request and attach suggested debdiffs in a couple of days.

To further elaborate the test suite starts with this little section
```
for i in $(seq 1 30); do
 echo "."
 xprop -root >/dev/null 2>&1 && break
 if [ $i -eq 30 ]; then
  echo "Failed!"
  exit 1
 fi
 sleep 1
done
echo
```
which I figured had been added instead of the 5 seconds sleep. I now see that this was in place all along and the 5 seconds are IN ADDTION. My bad.
