Bug#929834: Found a workaround which also solves other oddities

For me this was not the case. The UI would appear for half a second immediately after the light-dm shows up, and then disappear from all monitors. The mouse cursor would be visible. I have now installed slick-greeter and removed the file /etc/X11/xorg.conf that I added as the workaround. This has solved all the problems for me. signature.asc Description: PGP signature

I tried Alf’s workaround on a laptop on which Debian buster with an Xfce desktop was installed recently. I use this laptop, a Thinpad X220, mainly docked, alternating between one docking station with two external screens (display port + DVI) and one with a single external screen (DVI). When docked to the station with two screens most issues with light-locker have disappeared. Still, at one occasion there was a black screen after wakeup from suspend-to-RAM, and I had to kill light-locker form a text VT. But when docked to the other station (with one screen), lightdm does not show any user interface elements. The Debian background image is visible, but neither the window where the username/password is to be entered, nor the UI elements at the top right of the screen. Still, I can log in blindly. When locking the session, the same problem reappears. The greeter reappears again when I remove the file /etc/X11/xorg.conf that was created for the workaround. By the way, I ran “X -configure” also when docked to the station with the single screen and the resulting xorg.conf file is identical to the one that was generated at the other station.
Bug#943543: Acknowledgement (xfce4-screensaver: Black screen after unlock)
I filed this bug only after verifying during one night that it does not occur with xscreensaver. However, now I just observed it after a suspend period of a couple of hours. The package xfce4-screensaver cannot be the culprit, since it is no longer installed.
Bug#943543: xfce4-screensaver: Black screen after unlock
Package: xfce4-screensaver Version: 0.1.8-1 Severity: important Dear Maintainer, I upgraded to Xfce 4.14 from Debian bullseye. This involved xfce4-screensaver from unstable. (I'm actually unsure why it got installed. I have unstable in the APT-sources, but APT::Default-Release is set to "testing".) The screensaver is set to "blank screen". When unlocking after a system suspend or simple screen lock, first the unlock dialog is shown normally, but then, at least sometimes, the screen remains black. The mouse pointer is still visible, so this is not a problem of mode setting. The only way that I have found to return to a usable system is switching to a text console and killing xfce4-session. While I observe this problem sometimes after a very short lock, it occurs reliably after a long lock. Curiously, however, I could only ever observe it when using the built-in monitor of my laptop computer or one external monitor. With the two external monitors that I connect at work, I never saw it. As a workaround, I uninstalled xfce4-screensaver and installed "good old" xscreensaver instead. -- System Information: Debian Release: bullseye/sid APT prefers testing APT policy: (990, 'testing'), (500, 'unstable'), (500, 'stable'), (1, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 5.3.0-1-amd64 (SMP w/4 CPU cores) Locale: LANG=en_DK.utf8, LC_CTYPE=en_DK.utf8 (charmap=UTF-8), LANGUAGE=en_US:en (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages xfce4-screensaver depends on: ii libc6 2.29-2 ii libcairo2 1.16.0-4 ii libdbus-1-3 1.12.16-2 ii libdbus-glib-1-20.110-4 ii libgarcon-1-0 0.6.4-1 ii libgdk-pixbuf2.0-0 2.40.0+dfsg-1 ii libgl1 1.1.0-1+b1 ii libglib2.0-02.62.1-1 ii libgtk-3-0 3.24.12-1 ii libpam0g1.3.1-5 ii libpango-1.0-0 1.42.4-7 ii libsystemd0 242-7 ii libwnck-3-0 3.32.0-1 ii libx11-62:1.6.8-1 ii libxext62:1.3.3-1+b2 ii libxfce4ui-2-0 4.14.1-1+b1 ii libxfconf-0-3 4.14.1-1 ii libxklavier16 5.4-4 ii libxss1 1:1.2.3-1 Versions of packages xfce4-screensaver recommends: ii gir1.2-glib-2.0 1.62.0-2 ii gir1.2-gtk-3.0 3.24.12-1 ii python3 3.7.5-1 ii python3-gi 3.34.0-1 ii xfconf 4.14.1-1 xfce4-screensaver suggests no packages.
