Source: xorg Version: X.Org X Server 1.18.4 xorg-server 2:1.18.4-1 Build Date: 20 July 2016 Severity: important
to reproduce: install debian 9 on vmware, just "base system tools" and "ssh server", then apt-get install lightdm xorg-xserver-video-dummy xorg-xserver-video-vmware x11vnc; Xorg :0 -configure; now if you reboot, you're welcomed by the lightdm login screen, but if you do "cp /root/xorg.conf.new /etc/X11/xorg.conf" before you restart, you'll be welcomed by a black screen with a mouse pointer that moves around, but does nothing. it does not react to "ctrl+alt+delete" either. simiarly, if you install an xorg.conf for using video-dummy, like `wget https://gist.githubusercontent.com/divinity76/ce210b5dbcd9ea7d0585ac403caef577/raw/ -O /etc/X11/xorg.conf`, then reboot, then connect to the vm via ssh, then do `service lightdm status`, there you should see a line containing "-auth /var/run/lightmd/SOMETHING", then do `x11vnc -auth /var/run/lightmd/SOMETHING -display :0` , then connect to it via a vnc client (default port 5900), and you'll see that video-dummy suffers the same issue, it's just a black screen with a mouse pointer. doing the same steps on debian 8 works fine, eg, you're welcomed by the lightdm login screen. -- System Information: Debian Release: stretch/sid APT prefers testing APT policy: (500, 'testing') Architecture: amd64 (x86_64) Kernel: Linux 4.6.0-1-amd64 (SMP w/8 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages xserver-xorg depends on: ii x11-xkb-utils 7.7+3 ii xkb-data 2.17-1 ii xserver-xorg-core 2:1.18.4-1 ii xserver-xorg-input-all 1:7.7+16 ii xserver-xorg-input-libinput [xorg-driver-input] 0.19.0-1 ii xserver-xorg-input-wacom [xorg-driver-input] 0.30.0-1+b1 ii xserver-xorg-video-all 1:7.7+16 ii xserver-xorg-video-amdgpu [xorg-driver-video] 1.1.2-1 ii xserver-xorg-video-ati [xorg-driver-video] 1:7.7.1-1 ii xserver-xorg-video-fbdev [xorg-driver-video] 1:0.4.4-1+b4 ii xserver-xorg-video-intel [xorg-driver-video] 2:2.99.917+git20160706-1 ii xserver-xorg-video-nouveau [xorg-driver-video] 1:1.0.12-2 ii xserver-xorg-video-qxl [xorg-driver-video] 0.1.4-3+b1 ii xserver-xorg-video-radeon [xorg-driver-video] 1:7.7.1-1 ii xserver-xorg-video-vesa [xorg-driver-video] 1:2.3.4-1+b1 ii xserver-xorg-video-vmware [xorg-driver-video] 1:13.1.0-2+b1 Versions of packages xserver-xorg recommends: ii libgl1-mesa-dri 12.0.3-1
