Package: xfce4 Version: 4.12.5 Severity: normal Dear Maintainer,
* What led up to the situation? This is on a laptop msi CX61 2PC 8 GB RAM (no RAM problem), with an Optimus nvidia graphic card that is unused, no packages at all about it ; I only use the intel one. I have another screen (1920x1080) plugged on the VGA output that right-extends it's tiny display. As the Xfce4 fast user switch package disappeared (?), I use the lock screen trick to open a 2nd session for another user, flipping between both by locking again and re-login from one to another. As soon as the screen's locked, the power button goes orange (nvidia card) then (~10-12s) comes back to blue (intel) and then, both screens are off. I tried everything, but the only possible outcome is to CTRL-ALT-F1, which works and revive the laptop screen, then ALT-F7 to come back to Xfce, wait 5-6s, then the padlock appears on both screens, ~12s and the login screen of lightdm comes to live on both screens. * What exactly did you do (or not do) that was effective (or ineffective)? This is the only way I found to get the screens back to live after a lock. The problem is, it is a long procedure to switch from one user to the other. -- System Information: Debian Release: 10.1 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable') Architecture: amd64 (x86_64) Kernel: Linux 4.19.0-6-amd64 (SMP w/4 CPU cores) Kernel taint flags: TAINT_OOT_MODULE, TAINT_UNSIGNED_MODULE Locale: LANG=fr_FR.utf8, LC_CTYPE=fr_FR.utf8 (charmap=UTF-8), LANGUAGE=fr_FR.utf8 (charmap=UTF-8) Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages xfce4 depends on: ii gtk2-engines-xfce 3.2.0-4 ii libxfce4ui-utils 4.12.1-3 ii thunar 1.8.4-1 ii xfce4-appfinder 4.12.0-2 ii xfce4-panel 4.12.2-1 ii xfce4-pulseaudio-plugin 0.4.1-1 ii xfce4-session 4.12.1-6 ii xfce4-settings 4.12.4-1 ii xfconf 4.12.1-1 ii xfdesktop4 4.12.4-2 ii xfwm4 4.12.5-1 Versions of packages xfce4 recommends: ii desktop-base 10.0.2 ii tango-icon-theme 0.8.90-7 ii thunar-volman 0.9.1-1 ii xfce4-notifyd 0.4.3-1 ii xorg 1:7.7+19 Versions of packages xfce4 suggests: ii gtk3-engines-xfce 3.2.0-4 ii xfce4-goodies 4.12.6 ii xfce4-power-manager 1.6.1-1 -- no debconf information
