[Solved]Can't change resolution after selecting Nvidia driver

Post by fs0ciety » Tue Mar 26, 2019 1:50 am

So I installed Linux Mint, went through the starting guide, checked my drivers... The Nouveau driver was selected but the Nvidia driver said recommended next to it so I selected that, then restarted. Then when I boot up again I get a message that it's running in software mode and Cinnamon is running without hardware acceleration.

If I go to system settings and display, the resolution is stuck at 800x600 and there are no others available.

What do I do here?

What says the nvidia server settings?
Which graphic card?
which monitor?
What tells xrandr?

How is the monitor connected?
Have you tried another cable?

Did you reboot after installing the driver?
After you reboot - you can change Nvidia driver setting by going to

Code: Select all

Menu/Administration/Nvidia X-Server Settings
if it's not there then do this.

Code: Select all

sudo apt insall  nvidia-xconfig nvidia-settings
Then in a terminal type

Code: Select all

sudo nvidia-settings
you should be able to set your video from there.
good luck.

I found the Nvidia settings, but now how do I change the resolution? I don't really know what to do here. I can add rules or make a new profile and add keys to it, but I don't really understand what that is.

So... I figured it out. After doing some more research I found out the driver doesn't initialize if Secure Boot is enabled. I'd read about Secure Boot before, but I thought this was something exclusive to Windows 8 machines. I decided to check anyways and sure enough, it was enabled. Disabled it, restarted, boom, working right away in the correct resolution. Stupid.
