[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...

Not sure what is going on. I am able to run as many as 3 x-sessions, never tried 4. "start x /usr/bin/icewm -- :0" and changd ":0" to ":1" and .. each sessions starts and is usable.

"WINDOWMANGER=fvwm startx -- :1" works as user "root" and with Set-UID-Root for /usr/bin/Xorg in /etc/permissions.local also as normal user. It even works, if the normal (DISPLAY=:0) session is controlled by SDDM.
But the "new session" functionality of SDDM (also tried with KDM) does not work. Greetings, Björn -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org

My guess is that the display manager changes the permissions of some devices to be owned by the second "seat". Check sound, might have a similar problem. startx doesn't do those clever tricks, so it still works. I tried "switch user" on my 13.1 install (xfce and lightdm), and it works just fine. Proprietary nvidia driver, but I don't think that is involved. - -- Cheers, Carlos E. R.

50-device.conf as it comes from its rpm is nothing but comments, a dummy file except for a bit of instruction.

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."

Kernel 4.6 will provide support for the Maxwell graphic cards. I am not sure, if a Mesa and/or xf86-video-nouveau update will be necessary too. 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, I have three atm, twm, icewm-lite and plasma5. I started plasma5 with "systemctl isolate graphical" and the other with "starx /bin/... -- :#" from a <user> xterm but starting from a tty works as well.

Don't you use a display manager? I had to start "startx ..." from a text console because of permissions problems otherwise. I wonder why it works in an xterm on your side.

changes from runlevel x to runlevel 5, ie: graphical.target

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 have a laptop with tw which has used sddm for ~3 months now and haven't see this, but my max_days is set to 99999 (default) by which time the machine and me will *probably* have expired :) -- (paka)Patrick Shanahan Plainfield, Indiana, USA @ptilopteri http://en.opensuse.org openSUSE Community Member facebook/ptilopteri http://wahoo.no-ip.org Photo Album: http://wahoo.no-ip.org/gallery2 Registered Linux User #207535 @ http://linuxcounter.net -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org

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?

[1] https://www.reddit.com/r/archlinux/comments/4cojj9/it_is_probably_time_to_di... Good question. For my tests with nouveau I uninstalled the NVidia driver with "nvidia-uninstall". Unfortunately the uninstall-function is not complete. I had to remove the "blacklist nouveau" config file from /etc/modprobe.d and I had to remove the "nomodeset" setting from Grub.
To be sure, I also re-installed all Mesa libraries, build new initrd-files and I rebooted several times. Anyway, if I configured the "nouveau" driver I got the"Unknown chipset: NV117" errors in /var/log/Xorg.0.log: [ 105.407] (II) LoadModule: "nouveau" [ 105.408] (II) Loading /usr/lib64/xorg/modules/drivers/nouveau_drv.so [ 105.410] (II) Module nouveau: vendor="X.Org Foundation" [ 105.410] compiled for 1.18.0, module version = 1.0.12 [ 105.410] Module class: X.Org Video Driver [ 105.410] ABI class: X.Org Video Driver, version 20.0 [ 105.410] (II) LoadModule: "nv" [ 105.410] (II) Loading /usr/lib64/xorg/modules/drivers/nv_drv.so [ 105.411] (II) Module nv: vendor="X.Org Foundation" [ 105.411] compiled for 1.18.0, module version = 2.1.20 [ 105.411] Module class: X.Org Video Driver [ 105.411] ABI class: X.Org Video Driver, version 20.0 [ 105.411] (II) LoadModule: "modesetting" [ 105.411] (II) Loading /usr/lib64/xorg/modules/drivers/modesetting_drv.so [ 105.412] (II) Module modesetting: vendor="X.Org Foundation" [ 105.412] compiled for 1.18.2, module version = 1.18.2 [ 105.412] Module class: X.Org Video Driver [ 105.412] ABI class: X.Org Video Driver, version 20.0 [ 105.412] (II) LoadModule: "fbdev" [ 105.412] (II) Loading /usr/lib64/xorg/modules/drivers/fbdev_drv.so [ 105.413] (II) Module fbdev: vendor="X.Org Foundation" [ 105.413] compiled for 1.18.0, module version = 0.4.4 [ 105.413] Module class: X.Org Video Driver [ 105.413] ABI class: X.Org Video Driver, version 20.0 [ 105.413] (II) LoadModule: "vesa" [ 105.413] (II) Loading /usr/lib64/xorg/modules/drivers/vesa_drv.so [ 105.413] (II) Module vesa: vendor="X.Org Foundation" [ 105.413] compiled for 1.18.0, module version = 2.3.4 [ 105.413] Module class: X.Org Video Driver [ 105.413] ABI class: X.Org Video Driver, version 20.0 [ 105.413] (II) NOUVEAU driver [ 105.413] (II) NOUVEAU driver for NVIDIA chipset families : [ 105.413] RIVA TNT (NV04) [ 105.413] RIVA TNT2 (NV05) [ 105.413] GeForce 256 (NV10) [ 105.414] GeForce 2 (NV11, NV15) [ 105.414] GeForce 4MX (NV17, NV18) [ 105.414] GeForce 3 (NV20) [ 105.414] GeForce 4Ti (NV25, NV28) [ 105.414] GeForce FX (NV3x) [ 105.414] GeForce 6 (NV4x) [ 105.414] GeForce 7 (G7x) [ 105.414] GeForce 8 (G8x) [ 105.414] GeForce GTX 200 (NVA0) [ 105.414] GeForce GTX 400 (NVC0) [ 105.414] (II) NOUVEAU driver [ 105.414] (II) NOUVEAU driver for NVIDIA chipset families : [ 105.414] RIVA TNT (NV04) [ 105.414] RIVA TNT2 (NV05) [ 105.414] GeForce 256 (NV10) [ 105.414] GeForce 2 (NV11, NV15) [ 105.414] GeForce 4MX (NV17, NV18) [ 105.414] GeForce 3 (NV20) [ 105.414] GeForce 4Ti (NV25, NV28) [ 105.414] GeForce FX (NV3x) [ 105.414] GeForce 6 (NV4x) [ 105.414] GeForce 7 (G7x) [ 105.414] GeForce 8 (G8x) [ 105.414] GeForce GTX 200 (NVA0) [ 105.414] GeForce GTX 400 (NVC0) [ 105.414] (II) modesetting: Driver for Modesetting Kernel Drivers: kms [ 105.414] (II) FBDEV: driver for framebuffer: fbdev [ 105.414] (II) VESA: driver for VESA chipsets: vesa [ 105.415] (II) [drm] nouveau interface version: 1.3.1 [ 105.415] (EE) Unknown chipset: NV117 [ 105.415] (II) [drm] nouveau interface version: 1.3.1 [ 105.415] (EE) Unknown chipset: NV117 [ 105.415] (II) [drm] nouveau interface version: 1.3.1 [ 105.415] (EE) Unknown chipset: NV117 [ 105.415] (II) [drm] nouveau interface version: 1.3.1 [ 105.415] (EE) Unknown chipset: NV117 [ 105.416] (II) [drm] nouveau interface version: 1.3.1 [ 105.416] (EE) Unknown chipset: NV117 [ 105.416] (II) [drm] nouveau interface version: 1.3.1 [ 105.416] (EE) Unknown chipset: NV117 [ 105.416] (II) [drm] nouveau interface version: 1.3.1 [ 105.416] (EE) Unknown chipset: NV117 [ 105.416] (II) [drm] nouveau interface version: 1.3.1 [ 105.416] (EE) Unknown chipset: NV117 [ 105.416] (II) [drm] nouveau interface version: 1.3.1 [ 105.416] (EE) Unknown chipset: NV117 [ 105.416] (II) [drm] nouveau interface version: 1.3.1 [ 105.416] (EE) Unknown chipset: NV117 [ 105.416] (II) modeset(0): using drv /dev/dri/card0 [ 105.416] (WW) Falling back to old probe method for fbdev [ 105.416] (II) Loading sub module "fbdevhw" [ 105.416] (II) LoadModule: "fbdevhw" [ 105.416] (II) Loading /usr/lib64/xorg/modules/libfbdevhw.so [ 105.417] (II) Module fbdevhw: vendor="X.Org Foundation" [ 105.417] compiled for 1.18.2, module version = 0.0.2 [ 105.417] ABI class: X.Org Video Driver, version 20.0 [ 105.417] (WW) Falling back to old probe method for vesa [ 105.421] (==) modeset(0): Depth 24, (==) framebuffer bpp 32 [ 105.421] (==) modeset(0): RGB weight 888 [ 105.421] (==) modeset(0): Default visual is TrueColor [ 105.421] (II) Loading sub module "glamoregl" [ 105.421] (II) LoadModule: "glamoregl" [ 105.421] (II) Loading /usr/lib64/xorg/modules/libglamoregl.so [ 105.431] (II) Module glamoregl: vendor="X.Org Foundation" [ 105.431] compiled for 1.16.2, module version = 1.0.0 [ 105.431] ABI class: X.Org ANSI C Emulation, version 0.4 [ 105.431] (II) glamor: OpenGL accelerated X.org driver based.

This kernel should have support for my graphics card and has the necessary signed NVidia firmware binaries. Anyway, I would prefer a solution the NVidia proprietary driver. I do not use multiple X session so often, but I use other NVidia functions like VDPAU very often.
