trouble starting second xserver

Nareto · 2016-04-10 10:19:36

I'm using nvidia propietary drivers, lightdm as login manager and i3 as window manager. I want to play some games in Steam from Big Picture mode, but unfortunately this has some problems with i3, so I would want to start steam in a separate xserver (or maybe start a whole more "canonical" DE in another server, and start steam from there).

However all methods I found don't work for a reason or another, and I know too little about how X works to understand what's wrong. The method suggested in the wiki, here, gives me this:

$ xinit /usr/bin/xonotic-glx -- :6 vt$XDG_VTNR

somewhere I also found this command suggested, which gives the same error:

 $ startx cinnamon -- :7

pastebin of my ~/.xinitrc is here

as suggested somewhere I also created /etc/X11/Xwrapper.config with the single line "allowed_users=anybody" (I was getting an error before, something telling me I wasn't allowed as a user to start another server)

any ideas what I'm doing wrong??

This works for me:

startx /usr/bin/xonotic-sdl

To autostart on login to TTY6, add this line to ~/.bash_profile (~/.zprofile for zsh):

[[ -z $DISPLAY && $XDG_VTNR -eq 6 ]] && exec startx /usr/bin/xonotic-sdl

It's basically the same command I'm giving... I get the error no screens found. Looking at the log I posted I think these lines might be the culprit

after that it seems it's trying to use nouveau and other fallback drivers, not sure why. Here's the output of "lspci -v" relative to my video card:
