Are you on Desktop PC or Notebook computer? Is this a plugged in monitor or built in?
Its a desktop PC with 2 monitors
Same as me. I had some trouble on mine on the Nvidia Card ports - I plugged into the HDMI - Nvidia wanted me to use the Display Port instead. I used adapters and plugged both in Display Port and everything worked properly.
Can you please open a terminal and run
xrandr
and paste the output here?
I got
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 1024 x 768, current 1024 x 768, maximum 1024 x 768
default connected primary 1024x768+0+0 0mm x 0mm
1024x768 76.00*
sudo nano /etc/default/grub
What is the output of line: GRUB_CMDLINE_LINUX_DEFAULT=
Are you booting in Safe Graphics?
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
Did you Reboot after switching Drivers? If So:
Let's try setting the mode:
If connected by HDMI:
xrandr --addmode HDMI0 1920x1080_60.00
Or
xrandr --addmode HDMI1 1920x1080_60.00
If by Display Port:
xrandr --addmode DP0 1920x1080_60.00
xrandr --addmode DP1 1920x1080_60.00
I restarted the system after changing Drivers.
And the commands don't work, i get this result:
xrandr: Failed to get size of gamma for output default
xrandr: cannot find output "HDMI1"
This can depend on which port you are plugged into. Some cards have up to four.
I tried HDMI0 to 4 and DP0 to 4 but still nothing.
I went also to settings to About and i saw that in Graphics it said "llvmpipe (LLVM 12.0.0, 256 bits)" could this be the problem?
Hmmm... still looks like it is not using your Nvidia driver...
if you tap alt+F2 and enter in nvidia-settings, does it offer you the Nvidia XSettings Window?
Yes, but i see nothing in there
Can you please expand on this? Nothing in there in regards to resolution? Or nothing at all?
I mean that the app is empty, that's what i see:
Definitely looks like Nvidia is not installed.
Output of:
ubuntu-drivers devices
I typed this command to terminal and i got:
vendor : NVIDIA Corporation
model : GM204 [GeForce GTX 970]
driver : nvidia-driver-418-server - distro non-free
driver : nvidia-driver-510-server - distro non-free
driver : nvidia-driver-450-server - distro non-free
driver : nvidia-driver-390 - distro non-free
driver : nvidia-driver-470-server - distro non-free
driver : nvidia-driver-470 - distro non-free recommended
driver : nvidia-driver-510 - distro non-free
driver : xserver-xorg-video-nouveau - distro free builtin
What does this yield:
sudo apt install -f nvidia-driver-470
It's completed, do i need to restart my PC?
Yep, let's test...
Hi, sorry that you needed to wait long.
I restarted my system and i still have these issues. And on settings it says still that my graphics are "llvmpipe (LLVM 12.0.0, 256 bits)"
