which you mentioned, but out of context  :^)

you *do* have a problem, 
  ll /dev/nvid*
  crw-rw-rw- 1 root root 195,   0 May 23 09:22 /dev/nvidia0
  crw-rw-rw- 1 root root 195, 255 May 23 09:22 /dev/nvidiactl

well, something is amiss.

Log in as a user and w/o running anything, check the perms

then run:
  sudo SuSEconfig

this should set system file perms to the correct values.

you have set system file perms to: easy
chk:  yast2 -> security and users -> security center and hardening

past that, I can only thing of two possibilities:
  win domain problem
  system is rooted.

if *all* of your system exhibit this behavour, I would believe it is a
"win domain problem".

FLASH;  I changed perms on my system to match yours and ran picasa as a
normal user w/o a problem.  Something else is causing your problems
besides the perms (in addition to).  I would guess your problem lies in
the "win domain" access.

I know neither ???

If I can help further... I am around  :^)
