I have Ubuntu 14.04 on a Medion Erazer with the Nvidia GTX570M card. At first, while I had not installed the last nvidia driver, each time I would try to suspend my pc it would freeze frame on the login. Once I managed to install the nvidia drivers, everything seemed to work up until I noticed that suddenly the system settings would not open anymore. I then rebooted my pc, but when I logged in I just end up with my cursor but no top panel or side pannel. Thankfully, I had installed the gnome desktops which works, except for the fact the system settings do not open also in the gnome desktop.
I have tried following:
Problems after upgrading to 14.04 (only background and pointer after login)
except for reinstalling nvidia, since then I would be back at square one with suspend not working.
When I try to launch system settings through the terminal, I get:
simon@simon-X681X:~$ unity-control-center
libGL error: No matching fbConfigs or visuals found
libGL error: failed to load driver: swrast
(unity-control-center:2806): Gdk-ERROR **: The program 'unity-control-center' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadLength (poly request too large or internal Xlib length erro'.
(Details: serial 229 error_code 16 request_code 155 (GLX) minor_code 1)
(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 GDK_SYNCHRONIZE environment
variable to change this behavior. You can then get a meaningful
backtrace from your debugger if you break on the gdk_x_error() function.)
Trace/breakpoint trap (core dumped)
I know the 2 problems seem unrelated, but since they occured together, I am wondering if that is really the case.
Your help is much appreciated,
Simon
