The cool thing about adding the mamarley/nvidia PPA, one always gets the latest NVIDIA drivers afterwards through the normal Update Manager afterwards, that's how my last two were installed on my main PC running Linux MInt 17.1 MATE edition. Both inside of 10 days.
Unfortunately, it caused Cinnamon 17.1 that's so overrated to crash (the DE, not the entire OS) on my MSI notebook with dual graphics (Intel HD built in with a discrete GeForce NVIDIA 425M card. Maybe the notebook wasn't designed to use that driver, though it was running the Xorg of the same fine, and I also had the NVIDIA Control Panel. All of the panel items were gone and the only showing at the top, were Applications & Places, and no Terminal. Though I was able to access the Terminal by right clicking on the desktop & got it going again.
Will reinstall & start over, there's some broken dependencies, it only takes a couple of hours & the install is only 3 days old. No big deal to me.
If I have to use the Xorg drivers, of which I was offered several, including the 352, so it be. After all, it's 4 & a half years old, yet still a solid performer. Just wanted a taste of some Cinnamon, and all was going fine until I did the same as on the Dell. Sometimes, I just don't know when to quit for my own good & should have stopped at the instructions posted in Post #2 of this Topic & likely would have been fine. Though like my KDE trial, there's some things that doesn't work in Cinnamon as it does with MATE.
BTW, on that card, there is no advantage of having the NVIDIA 352 drivers, many are still on the more compatible 331 version.
The only thing about it, it's this same driver version for Windows installed & is working fine on both Windows 7 & 8.1 Pro on the same notebook. Though still, there's no advantage, other than having the latest driver, which goes to show, depending on hardware & OS, having the latest driver isn't the best choice.
Keep up the great work, Nick!
