Package: lightdm
Version: 1.2.2-4
Severity: normal
Dear Maintainer,
My system has two seats, each with its own video card, display, keyboard and
mouse.
The two seats are defined in /usr/share/X11/xorg.conf.d and referenced in
/etc/lightdm/lightdm.conf.
Seat0 uses a Radeon PCIE x1 card.
In lightdm.conf the X command for this seat is
xserver-command=/usr/bin/X -sharevts -novtswitch
so it uses VT7 and does not respond to <Ctrl><Alt>Fn keys.
Seat1 uses a Radeon PCIE x16 card.
In lightdm.conf, three [Seat:] sections are defined on this seat. The X command
for this seat is
xserver-command=/usr/bin/X
so it does respond to <Ctrl><Alt>Fn keys by switching VTs, and three users can
be signed in on three VTs.
Lightdm assigns the three [Seat:] definitions to VT8, VT9, VT10.
It's also possible to switch to VT1, ... ,VT6 and get a character mode
terminal.
Switches to VT7, VT11, ... also have an effect (see below).
This all seems to work, except that
- Seat1 responds to <Ctrl><Alt>Fn when it is keyed on Seat0's keyboard.
(Exception: If Seat1 is displaying VT8, VT9, or VT10, it will not respond to
<Ctrl><Alt>F7.)
- When Seat1 is switched to VT7, it echoes all characters keyed on Seat0's
keyboard.
Also, logging out of Gnome on Seat0 results in a VT switch on Seat1!
