this issue occurs on installed systems (my primary d960 which used to be
19.04, now 19.10), plus live systems (19.04 & 19.10, not when initially
booted; but when screens adjusted to be one above the other - but issue
only occurs one way; if swapped top-bottom both screens have
xscreensaver active
I have marked https://bugs.launchpad.net/ubuntu/+source/lubuntu-
meta/+bug/1807665 as a duplicate of this one.
This issue still occurs on my primary machine (19.10), and occurs
regularly if I test for it with 'live' with QA-testing (19.10).
Upstream have indicated an opinion that it'll be fixed
FYI: this also occurs on debian buster's weekly ISO of 2019-04-22 06:17

BSOD screensaver can be seen on top display; bottom display shows

guiverc: As per your comment 7 on LP bug 1814490, did you
test the other desktop environments also with the vertical positioning
of your displays, or could you do so now?
krytarik, FYI: Kubuntu 19.04 daily of jan 17 - no issues (as
booted (horizontal arrangement) & when

guiverc: Okay, thanks. Then it seems like the correct
package to file the bug report against is somewhere in the LXQt space.
guiverc: Try and "killall lxqt-powermanagement" and see if it's
still the same then?
Otherwise, only lxqt-session comes to mind as a possible
I rebooted x86 lubuntu 18.04.1 (no xscreensaver package is installed by
default)
added 'disco' universe (& main) repo's & installed xscreensaver
5.42+dfsg1-1ubuntu1
it pulled in a few requirements (updated libc6 & some other stuff)
set idle time to 1 min & let it run..; made sure it ran an
in #lubuntu-devel
guiverc: Okay. Try and reproduce this on a Lubuntu 18.04 Live
medium to perhaps exclude LXQt being a factor.
krytarik, does arch matter? (my box is x86_64, have found lubuntu
18.04 i686 thumb-drive) will that do?
or should i keep looking (or write a x86_64)?
No, can't
in #lubuntu-devel Krytarik suggested I try an older version
guiverc: From a quick web search and given the behavior, it
still seems likely that xscreensaver is at fault there though. Could
downgrade the packages you've got manually to the previous version here
and test if it's the same with
on this box I normally don't have LOCKED SCREEN enabled, but I get the
same result if that box is ticked or not. I tried changing screensaver &
it made no difference (my default was random anyway), and the issue only
occurs in Lubuntu (not Xubuntu) so it's likely a different package or
config at
