A day ago I try to get my graphics driver for Geforce GT 755M SLI installed on my Lenovo Y510P laptop. I read and tried at least 6 type of installing most of them just ruin the resolution from 1920x1080 to 1024x768 or 800x600 and no way I could change that. Others make this message This system is running in low-graphics mode, also tried to fix it but then my laptop just show me a black screen with a flashing dash. I reinstalled the OS a few times, backup didn't solved the resolution problem. I am really new to this whole Linux system, I had Windows before. I would appreciate any type of help, thanks!
Edit: Now the resolution is okay. But now when I try to watch a video in HD it's like a 360p like the driver not changed anything, checked a full hd picture and it's so "pixely" on my screen.
And most of the times when I moving the mouse random parts of the screen are flashing.
For lspci | grep VGA
I get this:
01:00.0 VGA compatible controller: NVIDIA Corporation GK107M [GeForce GT 755M] (rev a1)
It's only shows one card from the two...
Tried to revert for nvidia 304, but after it just booted me to black screen needed to reinstall Ubuntu
