[opensuse-factory] Launching multiple X sessions with proprietary NVIDIA?
With my old ATI Radeon graphics card and the Open Source driver radeon I was able to run multiple X sessions with one graphics card and one display, e.g. KDE Plasma on tty7 and GNOME on tty8. I tried the same with my NVidia card and the proprietary driver. The second X session (started from KDE Plasma 5 menu; display manager is SDDM) fails. /var/log/Xorg.1.log says: [ 29452.803] (II) xfree86: Adding drm device (/dev/dri/card0) [ 29452.803] (EE) /dev/dri/card0: failed to set DRM interface version 1.4: Permission denied [...] It isn't only a permissions problem. Also when I change the permissions on /dev/dri/card0 manually to crw-rw-rw-+ the second session does not start, but replaces the first session. I also tried this trick without success (/etc/X11/xorg.conf.d/50-device.conf is correct for openSUSE Tumbleweed): Launching multiple X sessions with proprietary NVIDIA on Xorg 1.16 https://wiki.archlinux.org/index.php/xorg#Launching_multiple_X_sessions_with...

Why proprietary rather than FOSS driver? I have GeForce 8400GS (GT218) running TW 20160406, without using startup xrandr or any non-default configuration in xorg.conf*, with Plasma sessions on tty3 (simply startx) and tty4 (startx -- :1) and IceWM (startx /usr/bin/icewm) on tty5, all same user login. Other than not finding them on tty7 & up where they used to be, they seem to work same as always, as with Intel or ATI gfxchips. -- "The wise are known for their understanding, and pleasant words are persuasive."

Since the proprietary driver can run multiple sessions with "startx", I doubt, that not the driver itself causes the problem. Maybe something with systemd, KDM/SDDM ...? Is there anyone who runs multiple sessions with KDE Plasma5 and KDM or SDDM and the NVidia driver successfully?

yes, was kdm, now sddm (early on I had many probs with sddn and switched back to xdm, but recently I opted to try sddm again and haven't had any *noticable* problems, yet)

permissions ???, I don't have a problem as long as Xorg is set suid, but that is necessary to used starx from a tty.

I was a little too quick in clicking send, omitting to ask if you tried running with neither nouveau nor nvidia drivers installed. I just found out 3 days ago[1] that the modeset driver built into Xorg works better than gfxchip-specific drivers for many, but forgot until after responding to you yesterday to try for myself. Could modeset be already working for Maxwell?
