At the moment I’m trying to set fan speed trough nvidia-settings because 334.21 driver don’t set it high enough to stop overheating, but when I try to start nvidia-settings in GUI mode (tried trough gksu, sudo, normal user) everything ends up in same SIGSEGV. Of course it works fine on Win8. Could you raise fix your thermal settings in this driver? or just fix this issue to let me do it myself? Thanks in advance.
