** Description changed: Lubuntu 19.04 [x86_64] installed system (upgraded from 18.04 85 days ago) ------------- addendums: 1: package suggestion by krytarik on #lubuntu-devel 2: possibly duplicate; & my reason why no (but linked for sure!) 3: occurs on QA-test of 19.04 daily 1:--- added re: package As for package - xscreensaver may not be culprit. It works perfectly on 18.04 Lubuntu (see comment #3 & #4 which tested prior & current package), and if I login via XFCE (Xubuntu) on same box (my install has both; comment #1). I tested killing lxqt-powermanagement which made no difference (comment #5) where it was suggested <krytarik> Okay, then I'd say just stick lxqt-session to the bug report too and see how it proceeds. :P 2: --- possible duplicate? I just discovered https://bugs.launchpad.net/ubuntu/+source/lubuntu-meta/+bug/1807665 which was for a 19.04 x86 QA-test on a laptop. I'm not marking it a duplicate as this system was installed 85+ days ago & yet I only discovered this issue now! If it were a straight duplicate I'd hope I'd have noticed it before now & seen connection with that prior bug.. On that other bug I noted I hadn't experienced it on any installed system, where now I have... 3:--- qa-test using daily image I booted today's daily image on different box which has two displays; at first it was good (displays next to each other horizontally). I adjusted position so they were vertically placed (like they are for that box, and this reporting box the bug-report relates to). I could re-create bug by using 'monitor settings' to a vertical placement & letting screensaver run. --- (end of addendum material) When the screensaver takes effect, both displays go dim & go black for maybe a second then one shows screensaver, the other returns to normal display. If i have windows (hexchat, htop/glances running) on the non-screensaver displaying window, those contents continue to receive updates allowing me to see new incoming messages in hexchat, or view the process info in htop/glances on a qterminal window. I logged out & tried same in XFCE and it blacked both screens the same, but then showed xscreensaver images on each display (not the same image, each with its own 'image'). My system has lubuntu-desktop & xubuntu- desktop intalled. I returned to Lubuntu & re-tested and it was the same (one display showing screensaver, one resuming active windows) To replicate: - login to Lubuntu 19.04 (on system with two displays) - have windows open on both displays, eg. htop so you can view detail change - change screensaver prefers to blank after 1 min, then wait as screensaver takes effect, both will dim, then one will display screensaver, other will return to displaying the window it was before with information (htop etc) updating as if unlocked. ---- i tried `ubuntu-bug xscreensaver` & it ran apport, then returned to $ prompt without browser to enter this window. this is my main desktop; x86_64 or dell [optiplex] 960 (c2q-q9400, 8gb, amd/ati cedar radeon hd 5000/6000/7350/8350) on that rare occasion I use it for qa-testing. this though was my installed normal system (so likely heavily modified) guiverc@d960-ubu2:~$ apt-cache policy xscreensaver xscreensaver: Installed: 5.42+dfsg1-1ubuntu1 Candidate: 5.42+dfsg1-1ubuntu1 Version table: *** 5.42+dfsg1-1ubuntu1 500 500 http://ftp.iinet.net.au/pub/ubuntu disco/universe amd64 Packages 100 /var/lib/dpkg/status guiverc@d960-ubu2:~$ uptime 14:36:44 up 2:23, 1 user, load average: 0.71, 0.76, 0.81 (the system was updated fully & has been restarted after updates) --- 2019-04-11 - This is not a Lubuntu only issue. - I recently installed opensuse tumbleweed over a sick leap install on my - hp 8200 elite sff (i5-2400, 8gb, nvidia quadro 600) box - and it - exhibits the identical behavior when using LXQt. + I recently installed opensuse tumbleweed over a sick leap install on my hp 8200 elite sff (i5-2400, 8gb, nvidia quadro 600) box - and it exhibits the identical behavior when using LXQt. + https://bugzilla.opensuse.org/show_bug.cgi?id=1132184
