no carga RO

[Hutch2]

Hola hasta ahora me funcionaba bien pero al bajar unas actualizaciones de la distro,uso solusos,no me deja entrar al juego me logueo,elijo servidor y desaparece,si ejecuto desde la terminal me manda este error :

NVIDIA: could not open the device file /dev/nvidiactl (Permiso denegado).
[S_API FAIL] SteamAPI_Init() failed; SteamAPI_IsSteamRunning() failed.
[S_API FAIL] SteamAPI_Init() failed; unable to locate a running instance of Steam, or a local steamclient.so.
NVIDIA: could not open the device file /dev/nvidiactl (Permission denied).

entre las actualizaciones entraba la de xorg,puede que tenga algo que ver? gracias de antemano.
la distro esta basada en debian;otra cosa si intento entrar como root :


The program 'rolauncher' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadWindow (invalid Window parameter)'.
(Details: serial 33 error_code 3 request_code 137 minor_code 4)
(Note to programmers: normally, X errors are reported asynchronously;
that is, you will receive the error a while after causing it.
To debug your program, run it with the --sync command line
option to change this behavior. You can then get a meaningful
backtrace from your debugger if you break on the gdk_x_error() function.)
