last/who/w command doesn't print out users using x

Hello,

I am using sddm (default on tty1) with awesome wm and all above commands don't track my X logins through sddm (if I execute startx on another tty it is displayed). Strange thing is that this seems to be the case since the 4th of may according to last commands output and I have been using this set up quite longer. I changed the display manager to lightdm with no change to the problem.

I'd really like to use the who command in a shell script so if anyone knows what could be wrong with my set up please help me

Re: last/who/w command doesn't print out users using x

Okay this has been a misunderstanding of the above commands on my side. I have been switching from xterm to urxvt a bit over a month ago and urxvt does not get listed as logged in (why?). What I actually tried to do was getting all DISPLAY variables of all users running a X session, so I have to find another way around my problem and it has nothing to do with last/w/who commands.

So I guess this can be closed. Sorry for the unecessary post.

ps -C Xorg -o args= | cut -c 28

You can try parsing

xauth list

thanks for the advice!

I've found another decent solution for my problem using logind's loginctl. The show-session command reports the user as well as the DISPLAY variable of the given user. Now I only have to parse the output and tada

That only works with DMs, doesn't it?

That is a good point. You are perfectly right xsessions started with startx are not being listed. Maybe even just for a subset of DMs (which use logind)?
