Hi @ all Since switching from Debian 10 to Debian 11, I've had a new small unsolved problem... with essentially the same customizing as before. It all takes place on my local Desktop-PC, where I have set up a restricted VM for actions in the internet. After I started the VM locally on my PC, I can operate the VM with the virtviewer without any errors. If I then open the second monitor via the Menu 'View->Display', a blank white window appears with the message "Waiting for display 2". xrandr correctly shows the second display as disconnected and also all available display-modes. After the following command xrandr --output Virtual-2 --auto --right-of Virtual-1 both (!) displays are white and both are waiting for a display.... and nothing works anymore. A previously started SSH connection to the VM from the PC shows the following for this moment: tom@pc:~ $ ssh 192.168.100.10 $ tom@vm:~ $su- Password: root@vm:~ # journalctl -f Apr 29 16:24:34 internet kernel: [drm] driver is in bug mode Apr 29 16:24:44 internet spice-vdagent[809]: Unable to find a display id for output index 2) Apr 29 16:24:44 internet spice-vdagent[809]: Unable to find a display id for output index 3) Apr 29 16:24:44 internet spice-vdagent[809]: Unable to find a display id for output index 2) Apr 29 16:24:44 internet spice-vdagent[809]: Unable to find a display id for output index 3) Apr 29 16:24:44 internet kernel: input: spice vdagent tablet as /devices/virtual/input/input7 It is no longer possible to restart the VM via "systemctl reboot", the VM is probably stuck in some systemd-timeouts, only "systemctl reboot -ff" leads to a reboot as a hard intervention. Does anyone know this problem? Is there a solution for this, to get the second display working? Below some relevant system-informations of my PC and the VM. root@pc:~ $ lsb_release -a Distributor ID: Debian Description: Debian GNU/Linux 11 (bullseye) Release: 11 Codename: bullseye root@pc:~ # uname -a Linux pc 5.10.0-13-amd64 #1 SMP Debian 5.10.106-1 (2022-03-17) x86_64 GNU/Linux root@pc:~ # cat /etc/libvirt/qemu/internet.xml | grep '<video' -A 3 <video> <model type='qxl' ram='65536' vram='65536' vgamem='16384' heads='2' primary='yes'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x02' function='0x0'/> </video> tom@vm:~ $ lsb_release -a Distributor ID: Debian Description: Debian GNU/Linux 11 (bullseye) Release: 11 Codename: bullseye tom@vm:~ $ dpkg -l | grep -i spice ii spice-vdagent 0.20.0-2 amd64 Spice agent for Linux tom@vm:~ $ systemctl status spice-vdagent.service ● spice-vdagentd.service - Agent daemon for Spice guests Loaded: loaded (/lib/systemd/system/spice-vdagentd.service; indirect; vendor preset: enabled) Active: active (running) since Fri 2022-04-29 16:00:56 CEST; 16min ago TriggeredBy: ● spice-vdagentd.socket Process: 847 ExecStart=/usr/sbin/spice-vdagentd $SPICE_VDAGENTD_EXTRA_ARGS (code=exited, status=0/SUCCESS) Main PID: 849 (spice-vdagentd) Tasks: 2 (limit: 4702) Memory: 944.0K CPU: 1.918s CGroup: /system.slice/spice-vdagentd.service └─849 /usr/sbin/spice-vdagentd Thanks and Best Regards Tom
