If your new to Linux I would suggest, In your applications there is Driver Manager that will install a Nvidia-driver for you.

i can use the terminal fine, but i need the steps to follow {:4_108:}

Launcher - DriverManager - Install NVidia XXX.XX+Deepin  - Reboot.
Good Luck!

Whe i arrive to my house, ill test, ty friend

Hi, After I installed Nvidia proprietary driver 340.96 (the latest) from the driver manager for my Nvidia FX4600 the whole screen crashed after login. Only the default Nouveau driver works. I have tried it after a fresh installation of Deepin 15.1. For the reference The same issue with Manjaro Deepin.

Hi, Welcome to the Deepin Forum. Some of the legacy Nvida cards are no longer supported with the proprietary driver and is better to use the open source.

Nouveau now no longer works on my nvidia-based PC - from startup, graphic glitches progressively get worse, until it finally lock up, which only takes a few minutes!  As a last resort, I tried the official current nvidia installation, and was relieved to find it worked perfectly.  The nvidia driver before that wouldn't work at all!  So, it's a mixed bag...

Yes it is a mixed bag when using the proprietary graphics cards. Hopefully we will get better hardware support with the new Deepin Kernel Plan.
