I installed Ubuntu 14.04 LTS 64bit on my PC. After I've installed nVidia drivers (recommended) to solve the problem of the cursor that vanishes, Ubuntu freezes randomly when I'm working, I mean that the system doesn't react to my actions.
System Config are :
Sony F Series, GeForce GT 740M/PCIe/SSE2, Intel Core i5-3337U [email protected]×4, RAM 8gb
I think there is the issue with my graphic card. I am presently using "NVIDIA binary driver - version 331.113 from nvidia" as my graphics card driver.
