Default works under root but not under normal users

hi

i've installed nvidia package drivers... it works correctly... but under root only

when i want to log under other user i've a black screen and it fastly return to the loging window...

i can imagine it's a question of rights... but on which file?

i would like to ask here what to do to have 3d hardware acceleration under my linux under a single user session????

many thanx to all helpers...

If it crashes it must leave error messages in the console, if you could paste them it would be of help.

i don't enter at all when trying to connect under a normal user... so i don't have any message... really anything i can see... maybe there is a log somewhere... but i don't know where...

i don't have a Xorg.0.log on my system, only a XFree86.0.log... but very long, i think too long to paste it here... i've had a glance at that, and i didn't see any error... which section approximatively do you want me to show you?

here's the result of tail /var/log/messages:

Default Re: works under root but not under normal users

Under the post entry box there is 'Additional Options' where you can attach your log, rather than post the contents (that allows users to read it only when they need).

Often this problem is caused by permissions being incorrect on the files /dev/nvidia*, so check them.
ls -al /dev/nvidia*

Your user should own them and have read/write permission if PAM is managing the file perms for those devices (as soon as you log in they should be set this way), if it is not or the files only have root access change them and see if that fixes the problem. Ideally this is not how perms should be managed.. but it might make it work for you.

chmod o+rw /dev/nvidia*

pam is black magic, if its broken and managing permissions incorrectly I probably can't help fix it right
