Post subject:  Default mythtv user cannot login to gdm
The mythtv user created during install and used to run the myth frontend cannot log into the gdm.

When the gdm starts it tries to login as the mythtv user and fails - it then tries every thirty seconds and fails.

I can log in as root, but running the frontend as root causes it to not see and have access to the /dev/video0 it needs to watch or record tv.

Nothing that I know of in the system was changed for the user. I edited the XFConfig-4 and ivtv to make TV-Out work on my PVR-350 - don't think those are related though. I did run the setup scripts here: http://mysettopbox.tv/phpBB2/viewtopic. ... ght=pvr350

* The file system partitions are not full.
* There are not duplicate user or group entries for the mythtv user.
* I do not see anything in the OS logs pertaining to this user.
* The backend log simply states it cannot access /dev/video0
* I reset the password to be sure it was correct.

When I login thru SSH using the mythtv user it is trying to run something that repeatedly returns -sh: /dev/null: Permission denied. - also not sure if this is related. /dev/null reads as: crw-rw-rw- 1 root root 1, 3 Oct 12 00:48 /dev/null - looks correct...

[edit] this is an R5A16 clean install [/edit]

Anyone run into this before?

yup, home dir exists named mythtv and owned by mythtv.

It contains 3 directories - Desktop, GNUstep, tmp.

What are the permissions on "/dev/video0" and does the mythtv user belong to the right group?
Code:
root@black2:~# ls -al /dev/video0
crw-rw----  1 root video 81, 0 Jun 21 23:12 /dev/video0
root@black2:~# grep video /etc/group
video:!:44:mythtv

Yup, it looks correct:

/dev/video0 = crw-rw-rw- 1 root video 81, 0 May 23 17:50 /dev/video0
group = video:!:44:mythtv

This is through an ssh session so obviously it won't start X but it shouldn't be giving those /dev/null errors either - /dev/null is setup and working for everything else in the system.

Well, never found a solution.

Even a remove and recreate of /dev/null didn't help - always worked for the system use of /dev/null but for some reason no regular users could make use of it - even though permissions were correct.

I ended up re-installing - took less time to reinstall and make things work than the time I spent trying to solve this problem.
