GF108M [GeForce GT 635M] Nvidia Graphics card, and have ubuntu 14.04 os. Every 10 minutes or so it freezes. Alt+Ctrl+F2 and Alt+Ctrl+F7 is my temporary solution. What do I do to fix this?
lspci -k | egrep 'VGA|3D' -A2 gives the following output:
00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09)
Subsystem: ASUSTeK Computer Inc. Device 1447
Kernel driver in use: i915
01:00.0 VGA compatible controller: NVIDIA Corporation GF108M [GeForce GT 635M] (rev a1)
Subsystem: ASUSTeK Computer Inc. Device 1447
Kernel driver in use: nvidia
Well, re-installing the latest driver would the first step of course. First try using the Software & Updates to install the latest proprietary and preferably tested driver.
Open the Ubuntu Software Center, move your mouse to the top, from the Edit menu, choose Software Sources . Click on Additional Drivers tab, wait for it to load the information and choose the latest proprietary for the NVIDIA. For me (GeForce GT 730) at this time it shows:
Using NVIDIA binary driver - version 346.59 from nvidia-346 (proprietary, tested)
Click on Apply and wait for it to install it. If your screen keeps crashing during this process, then you won't have a choice other than trying to install it from terminal.
