Multi-users on multi TTY behavior ?

[Member oops]

Hello all,
Does a way already exist into antiX to have/open multi-users on multi TTY (ex:sudo chvt 7, chvt 8, chvt 9,… or via “mx-switchuser” like into MX, Ctrl+Alt F7/F8,etc) ?

chvt, via “Ctrl+Alt F7/F8,etc”?
Yes.

switchuser, multiple Xsessions… already?
no.

mx-switchuser utilizes LightDM and “dm-tool switchuser” (vs SLiM)

Thank you for this confirmation Skidoo.
Maybe a work around then (via startx or so) within Slim ?

unsure what specific functionality you’re missing, and wanting.
Workaround? Can’t force a blue peg into a red hole… so perhaps you should, instead, investigate some of the SLiM alternatives.

sddm
gdm
mdm
lightdm

… I only want to be able to switch to 2 or 3 user sessions via Ctrl+Alt F7/F8.F9 … so with SLiM 1.3.4 it is impossible yet.
Thank you for your proposed alternatives above.

I have not done so in a while so my memory is fuzzy. At the least this may give some ideas for poking around.
From my memory having multiple x sessions in different vt (7(default)+8+9) could be done in a couple of different ways.

One way was to have several sessions opened as different users during init. I think this was done with getty and inittab… and having a session started as a specified user then immediately running startx. (which would at them moment be startx /usr/local/bin/desktop-session)

Another way was to have a script that made one call per X session, but passed different vt options to the X server. IIRC the commands went something like (with addition of desktop-session)
startx /usr/local/bin/desktop-session rox-icewm :1 -vt7
startx /usr/local/bin/desktop-session space-fluxbox :2 -vt8
startx /usr/local/bin/desktop-session jwm :3 -vt9
This script was run manually after logging into a text session. It also used the same user account which I seem to remember some programs having a fit about multiple instances running.

There is also something in my memory about mucking with /etc/init.d/slim, and adding a second start / stop line. In between the second and first line was a mv/cp (or was it rm / ln ?)command to move the /etc/slim.conf around between multiple versions. Each version of the slim.conf had a different xserver_arguments line specifying a different vt. I cannot recall if this ever worked or not but the idea was to have slim started on 3 different spaces (Control + Alt + 7/8/9).

This was quite a while ago before I added multiple graphics cards and running with an actual multiseat sytem.

Oh wow; posted in 2010! Has it really been that long?!? No wonder my memory is a little fuzzy about this LOL

Edit:
I seem to recall user BitJam also runs X in multiple vt sessions for testing. Perhaps he will chime in about it.

Thank you Dave for these accurate information, I will do some tests and try to keep Slim (only 9MB – slim)(at least= 9MB+5MB- lightdm),

echo "------------------------------------" && mem=0 && while read -r rss comm ; do mbs=$((rss/1024)); mem=$((mbs + mem)); echo $mbs"MB - $comm"; done <<< "$(ps -u $USER -wo rss=,comm= --sort -rss)" && echo "------------------------------------" && echo $mem"MB: Memory used by user '$USER'"
------------------------------------
26MB - Xorg
9MB - slim
6MB - cupsd
5MB - console-kit-dae
5MB - polkitd
4MB - bash
3MB - haveged
...

FOR MX18 ( at least= 9MB+5MB- lightdm:
echo "------------------------------------" && mem=0 && while read -r rss comm ; do mbs=$((rss/1024)); mem=$((mbs + mem)); echo $mbs"MB - $comm"; done <<< "$(ps -u $USER -wo rss=,comm= --sort -rss)" && echo "------------------------------------" && echo $mem"MB: Memory used by user '$USER'"
------------------------------------
32MB - Xorg
13MB - smbd
12MB - NetworkManager
10MB - ModemManager
9MB - cups-browsed
9MB - udisksd
9MB - polkitd
9MB - lightdm
7MB - lpqd
7MB - cupsd
7MB - upowerd
6MB - bash
5MB - lightdm
5MB - accounts-daemon
5MB - nmbd
5MB - smbd-notifyd
4MB - su
4MB - wpa_supplicant
4MB - bluetoothd
4MB - cleanupd
4MB - haveged
3MB - systemd-logind
3MB - rsyslogd
3MB - dhclient
3MB - ps
2MB - systemd-udevd
2MB - cgmanager
2MB - cron
1MB - rpcbind
1MB - getty
1MB - init
...

… Or maybe just as a workaround, to show at the login slim prompt, the list of the available users.

cat /etc/passwd | grep “:/bin/bash” | sort | cut -d: -f1
User1
User2
User3
…

PS: Slim is interesting into antiX, because only few process are actives :

I like the solution in MX Linux in the whisker menu “dm-tool switch-to-greeter”.

If I want to run a second session in antix 21 under Ctrl+Alt+F8, I run the following command in roxterm:
nohup sudo xinit /usr/bin/roxterm -e “sudo -u anyuser /usr/local/bin/desktop-session zzz-icewm” — :1
The roxterm windows must always remain open.
Does anyone have a better solution?
