Computer becomes Sluggish, and slow to respond then eventually freezes when woke up using 352.63-0ubuntu0.14.04.1 . I would have to shut down the computer improperly in order to get it back to normal.
Changed driver to Open source version, issue is gone.
IME upgrading Linux Mint 17.3’s stock kernel ver. 3.19.x to 4.2.x wily via Synaptic Package Manager will improve system response.
Reverting to an earlier known-good version of the nVidia driver or conversely to an even newer version is what I’ve done on the exceedingly rare occasion that I’ve experienced GPU driver issues on a PC-BIOS-based or CSM-enabled UEFI-based AM3+ system under Linux Mint 17.3 MATE.
