Multi seat on Debian9
Dear support,
I am trying to build a double-seat system with one of the screens connected via a DisplayLink adapter (from Kensington, still in USB2, it is a DL165). The operating system is debian9 on a SSD with 2 seats defined: seat0: Nvidia 9300 GPU with the Nouveau driver (works great) + keyboard + mouse + everything else Seat1: DisplayLink adapter + keyboard + mouse seat1 Sessions: *c1 Devices: ├─/sys/devices/pci0000:00/0000:00:1a.1/usb2/2-1/2-1:1.0/0003:413C:301A.0004/input/input7 │ input:input7 "PixArt Dell MS116 USB Optical Mouse" ├─/sys/devices/pci0000:00/0000:00:1a.7/usb6/6-4/6-4.4/6-4.4:1.0/drm/card0 │ [MASTER] drm:card0 │ └─/sys/devices/pci0000:00/0000:00:1a.7/usb6/6-4/6-4.4/6-4.4:1.0/drm/card0/card0-DVI-I-1 │ [MASTER] drm:card0-DVI-I-1 ├─/sys/devices/pci0000:00/0000:00:1a.7/usb6/6-4/6-4.4/6-4.4:1.0/graphics/fb0 │ [MASTER] graphics:fb0 "udldrmfb" ├─/sys/devices/pci0000:00/0000:00:1a.7/usb6/6-4/6-4.5/6-4.5:1.0/0003:413C:2107.000A/input/input13 │ input:input13 "DELL Dell USB Entry Keyboard" ├─/sys/devices/pci0000:00/0000:00:1d.2/usb5/5-2/5-2:1.0/0003:0A81:0205.0005/input/input8 │ input:input8 "CHESEN PS2 to USB Converter" └─/sys/devices/pci0000:00/0000:00:1d.2/usb5/5-2/5-2:1.1/0003:0A81:0205.0006/input/input9 input:input9 "CHESEN PS2 to USB Converter" The Xorg server has been launched by lightdm and is running but the screen is not active (no login screen) /usr/lib/xorg/Xorg -sharevts :0 -layout SecondLayout -seat seat1 -auth /var/run/lightdm/root/:0 -nolisten tcp Nothing special in the Xorg.0.log file, apparently everything is "working" except the screen which behaves "strangly". For example * There are still messages from the boot on the screen while lightdm is supposed to ask for login. *When I login (blindly) the splash screen appears with a mouse pointer but it is static and stays like this forever * the desktop manager (xfce4) is properly launched but unusable. Do you have any idea in which direction to look at ? Thanks for your help Jerome Kieffer |

Found the solution
Hi,
I found the solution:
Apparently this stopped working with the newer USB3 display-link devices ... it is a bit sad as it is exactly MY use-case. At least I will not spend money on a new device |
