[SOLVED] user cannot login into KDE session after upgrade

[magfan]

Upgrading from Mageia 1 to Mageia 2 went smoothly as mentioned before. But another strange thing is that only one user cannot login into a KDE session. Removing ".kde4" from the $HOME-directorty did not work. Deleting the user (but keeping the $HOME-directory) and re-creating him did also not work. What else could I try to make that users account accessible again?

I just realized that only this user gets some .xsession-errors:

check the ownership of the users /home You may have a mismatch in uid or gid numbers

Please show the output of

Code: Select all

ls -la /home

and the output of

Code: Select all

id username

(replace username by the name of the user who has those problems)

To me it looks fine. The bad thing is that "mer" is my own account...

Code: Select all

[root@cortex]# ls -la /home

Well, deleting the user including the $HOME directory and re-create the same user including a new $HOME directory solved the problem. What remains is copying personal data back (thanks for a good backup!)

I know I should mark this topic as [solved], but can edit only three more letters in "Subject:"


Added:
I finally found the reason after copying thousands of files. But to keep the message short:

Never set QTDIR in .bashrc!!!

In Mageia 1 it was still OK. But now it seems to me that when a user logs in a KDE session and in .bashrc the system value of QTDIR is changed all paths for KDE programs are mixed - which results in an immediate shutdown of the KDE session.

Maybe try editing the title of your initial text, or shortening it somehow.

Being curious, for what purpose did you put it there?

Well, sometimes I have to develop programs with Qt and often it happened that the version I was using was newer than the systems Qt version. But this time it is the opposite case. My laziness killed two days. Of course I should set QTDIR only in my IDE. You know, it is a habit from the times when I developed software only in an xterminal.
