I'm really trying to avoid reinstalling because I've installed a lot of software and customized a lot. I'm running Gnome 17.04.
My graphics card is a hybrid GTX 960M.
lspci shows these lines;
00:01.0 PCI bridge: Intel Corporation Skylake PCIe Controller (x16) (rev 07) 00:02.0 VGA compatible controller: Intel Corporation HD Graphics 530 (rev 06) 01:00.0 3D controller: NVIDIA Corporation GM107M [GeForce GTX 960M] (rev a2)
So both are being detected.
I never touched any graphics drivers until last week. I just used whatever was installed by default. I made the now apparent mistake of switching to proprietary drivers in the "Additional Drivers" section of "Software & Updates".
At first it was ok.
nvidia-375 was installed. When opening the NVidia X Server Settings application, the Intel PRIME profile was selected. I switched it to NVidia and rebooted and graphics performance became horrible, especially for games. Major screen tearing and tons of heat from the graphics card.
If I switch back to Intel, I'm unable to login. I get the login screen, but when I enter my password, I just get a flash, and then I'm back at the login screen. Nothing I can find in logs to help. I can switch to another non-graphical console and do
sudo prime-select nvidia and then I can log in again. But I don't want to use this anymore because the performance is horrible, and the laptop gets WAY too hot. Even scrolling webpages is choppy, and YouTube videos look much worse, choppy and tons of tearing.
Back in the Additional Drivers, I can switch back to the XOrg Nouveau driver, but then for some reason, when I start Steam, everything locks up. I'm unable to use Chrome, and even if I kill Steam, my network connection seems blocked.
At this point, I think I'd like to go back to however it was when I first installed, but I can't seem to get it back. Just using the Intel graphics was fine because I don't play heavy 3D games, mostly side-scrollers.
This is my first laptop with NVidia, I've always stuck with AMD. So I'm a little lost on how to get this going.
The laptop is an MSI Leopard Pro.
