Public bug reported: Ubuntu release:
Ubuntu Bionic Beaver (development branch); the problem also occurs in Kubuntu 17.10, if upgraded to Plasma 5.12.x Package version (plasma-workspace): Installed: 4:5.12.4-0ubuntu2 Candidate: 4:5.12.4-0ubuntu2 Version table: *** 4:5.12.4-0ubuntu2 500 500 http://de.archive.ubuntu.com/ubuntu bionic/universe amd64 Packages 100 /var/lib/dpkg/status What I expect to happen: To continue where I left off after waking up my screen What happens instead: When the screen (external monitor, not a laptop) turns off due to a timeout, whether this was set in Plasma's power management settings or using xset dpms <whatever>, and I wake it back up again to continue working/faffing around online, any widgets have vanished and the desktop is a solid, unresponsive black. The rightmost edge of my panel is still visible in the top left corner of the screen. "Hot corners" and compositing still work; windows are still decorated. Apport is silent. This does not happen if I wake the screen back up within the first couple seconds, but after ten seconds or so it happens reliably every time. It also does not happen when I don't set PLASMA_USE_QT_SCALING=1 (but I use a Hi-DPI screen and would rather have Plasma scaled correctly). Using Xorg. Proprietary Nvidia driver, tested with 384 and all 390 point releases. ** Affects: plasma-workspace (Ubuntu) Importance: Undecided Status: New ** Attachment added: "Screenshot of what it looks like" https://bugs.launchpad.net/bugs/1760319/+attachment/5097047/+files/Screenshot_20180331_174125.png ** Summary changed: - Widgets and desktop/wallpaper gone after screen timeout if PLASMA_USE_QT_SCALING=1 + Widgets and desktop/wallpaper gone after waking from screen timeout if PLASMA_USE_QT_SCALING=1 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1760319 Title: Widgets and desktop/wallpaper gone after waking from screen timeout if PLASMA_USE_QT_SCALING=1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/plasma-workspace/+bug/1760319/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
