[SOLVED] Debian

nomadic101 · 03-21-2021, 11:38 AM

Hello

I'm running debian 10 (x64). I originally installed with root password, and one main user.

After installing, in terminal it indicated I didn't have user privileges when using sudo so I followed these instructions.

Now, sometimes after rebooting, my username and/or password isn't recognised. The screen re-displays login after inputting info.

I can login as root, reset user password.

But then it can be forgotten again.

Any advice?

Thanks

we need more details, especially what desktop is it? Did you install/configure any language specific setup? How did you try to log in (on console or GUI)?

Hi

desktop:LXDE
Trying to login via GUI which is the problem.
No language specific set up

I just tested, I can login as user via console from another machine on my lan. But as I said, not GUI

thanks

BTW, the command nano /etc/sudoers in instructions you linked to is pretty dangerous. Much safer would be

Code:

EDITOR=nano visudo

Can you login on the same machine from a virtual console (say Ctrl+Alt+F3)?

The the problem could be some files in your home directory owned by root that shouldn't be.

Code:

namei -l ~/.{ICE,X}authority

Code:

sudo find ~ -not -user $USER -ls

Code:

grep '(WW)\|(EE)' /var/log/Xorg.0.log

Hi

I can login on same machine.

Code:

root@debianserver:~# namei -l ~/.{ICE,X}authority
f: /root/.ICEauthority
drwxr-xr-x root root /
drwx------ root root root
                     .ICEauthority - No such file or directory
f: /root/.Xauthority
drwxr-xr-x root root /
drwx------ root root root
-rw------- root root .Xauthority

Code:

sudo find ~ -not -user $USER -ls

no output

Code:

root@debianserver:~# grep '(WW)\|(EE)' /var/log/Xorg.0.log
	(WW) warning, (EE) error, (NI) not implemented, (??) unknown.
[   326.064] (WW) The directory "/usr/share/fonts/X11/cyrillic" does not exist.

No. I mean login as a regular user, not as root.

nomadic101 · 03-21-2021, 01:03 PM

Ah, yes realised that!

Code:

sanjserver@debianserver:~$ ls -lah | grep -i Xauthority
-rw-------  1 root       root        163 Mar 21 14:57 .Xauthority

sanjserver@debianserver:~$ find ~ -not -user $USER -ls
  4591350      4 -rw-------   1 root     root          163 Mar 21 14:57 /home/sanjserver/.Xauthority

sanjserver@debianserver:~$ grep '(WW)\|(EE)' /var/log/Xorg.0.log
	(WW) warning, (EE) error, (NI) not implemented, (??) unknown.

Then

Code:

sudo chown sanjserver.sanjserver .Xauthority

Thanks - that worked. (And I learnt something).
