Debian - after changes x works for root but not for user (nvidia, i3)


After making system changes, my desktop x-windows immediately hangs when loading as a regular user, but works (mostly) if I invoke it as root. Everything else seems to work, though there are several errors in dmesg regarding the video setup. The changes I made include: getting rid of systemd, then upgrade then dist-upgrade. I did the same changes on a laptop with no problems.

I'm using a dual monitor system with the NVIDIA Corporation GM107 [GeForce GTX 750 Ti].

I'm using Debian with the i3wm (the i3 window manager). I have always had this machine set to boot to the command line and invoke the gui with "startx". I do not use any Xorg.conf file anywhere, though I can't say why, there just isn't any on the system. I don't understand how these various pieces work together! So I could use some advice on how to proceed in analyzing this problem.

I've tried to make the root account and the user account the same by renaming the user specific files (.Xsession, and i3 config stuff).

So what files are making the gui hang when my regular user account tries to load it but allows my root account to run it?

nvidia-settings won't run, gives errors:

Code:
root@ada:~# nvidia-settings
X11 connection rejected because of wrong authentication.
Unable to init server: Could not connect: Connection refused

ERROR: The control display is undefined; please run `nvidia-settings --help` for
	   usage information.
Here are some sections from dmesg:

Code:
64655-[   61.680383] NVRM: Your system is not currently configured to drive a VGA console
64739:[   61.768912] NVRM: on the primary VGA device. The NVIDIA Linux graphics driver

For testing, I rm'd the /var/log/Xorg.0.log. Then when logging on as my regular user account and invoking startx (which immediately hangs) I see that a new /var/log/Xorg.o.log file was not created.

I then exit, and re-login as root and invoke startx. Here is the /var/log/Xorg.0.log that is then created:

Code:

Check if your user is in video group, add if necessary. User needs access to /dev/dri/card0.

Thanks for the suggestion Emerson.

My user account was a member of video group.

The /dev/dri/card0 was not readable for world, so I chmod 777 but it made no difference. It is now:

Code:
keith@ada:~$ ls -ahl /dev/dri/card0
crwxrw-rwx+ 1 root video 226, 0 Mar 24 16:26 /dev/dri/card0
This is my personal home desktop which no one else uses, ever.

root:video seems about right. With the user in the video group. Remember to log in again to change the groups if that was a change. You might check $HOME/.Xauthority, if it is owned:grouped by someone other than the owner of $HOME, that could be an issue. Deleting it before starting X should help in that case. Depending on distro anyway, but that's a typical usage for .deb based ones.

Not that you should, but the user who started X can:

$ xhost local:

And any user should have access to X. Not that one should do that when starting X as root. Note that you might have to manually set $DISPLAY to use X as the user who didn't start X. Plus various don't do that as root scenarios. In the days of OLD you also needed a "SECTION "DRI"" in the xorg.conf with group and mode settings. But most distros are good about having that as a default these days.

Hi Shadow 7-

Thanks, I removed all restrictions from my user .Xauthority, and that made no change, so I tried simply deleting it and that mad eno change either.

As a user, when I host local: I get this:
Code:
keith@ada:~$ xhost local:
xhost   unable to open display ""
I then tried:
Code:
echo $DISPLAY
and it returned nothing.. a blank line. Actually, both my user account and the root user got those same results.

Yes, I had exited and re-logged in to make sure the groups were set.

Here's more detail:

Which files do I need to delete/re-install in order to start from scratch?

Thanks for your help!

$ COLUMNS=300 ps faux | grep X

The X should be running and one of the parms something like :0

$ export DISPLAY=":0"
$ xvidtune -show
$ xcalc

If you're running something like debian you might want to tasksel and select desktop.

$ sudo tasksel

It is mighty odd that DISPLAY isn't set though, and you definitely have some things missing. For distros like ubuntu, you can get most of what is needed with:

$ sudo apt-get install ubuntu-desktop

Thanks, but no, I don't want a DE. My i3 window manager is fine. I just need to get the video fixed.

Code:
keith@ada:~$ export DISPLAY=":0"
keith@ada:~$ xvidtune -show
Error: Can't open display: :0
If you look back a few messages you will see I already show the output from ps aux | grep x showing what gets loaded.

So my question now is- how to get the video back to square one so I can reload whatever is needed?

Thanks

After more than a week trying to figure this out, I finally just put systemd back in... and now everything is working.

This is very strange... I had no problem eliminating systemd on my laptop, but then my laptop doesn't use nvidia drivers! So... what? evidently the Debian nvidia-driver package has some kind of hooks that require systemd? Very aggravating!!!
