Dear all,

to fix this issue permanently so that I can quickly switch between multiple
accounts and I'm also able to resume from suspend my laptop I added the
following options into:

 - added radeon.dpm=0 radeon.runpm=0 to grub so that kernel will load 
   radeon without enabling the power management features

 - created file /etc/modprobe.d/radeon-pm.conf with the following content:
      options radeon runpm=0
      options radeon dpm=0

   *this will make kernel driver to read the same options after resume 
    from suspend

Regards,

Luca
