This going to sound like a tedious link, but I thought I should share incase anyone else has this.
So I have a problem where my "nvidia graphics driver" stops and has to be restarted since installing the beta (recent deskscapes purchaser so very greatful for the free upgrade). This occurs roughly 30 seconds after getting to desktop. Tho it is hard to gauge if it is a driver loading or an app causing the problem as even my network controller isn't initialised before I get to desktop thanks to an SSD and a 3930k cpu.
On the same day I also had installed a new cooler on my gfx card so I have taken to using nvidias overclocking and control software to alter the fans on the new cooler. The reason I mention this is this is that this loads a profile right after boot. (I have since disabled this and the fault remains).
I must mention I have 0 problems in games and deskscapes itself is running faultlessly.
I will update if I find out more. Going to go check for a newer driver. Failing that I may clean out and re-install it.
