I'm having this issue that when I load up the system Zorin Core, I'm getting set to 640x640 resolution I've tried to fix it but I get the error message "Can't find gamma of the display" and well so far I've tried to force it with grub but didn't work neither did using xrandr work.
Can you please run
sudo nano /etc/default/grub
On this line
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
add the nomodeset
parameter so that it looks exactly like
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset"
Tap ctrl+x to exit, then the y
key to say yes to save, then the enter
key.
Run
sudo update-grub
Reboot and test...
Didn't work sorry for the late response I went to college.
Are you using Nvidia, Intel or AMD Graphics card?
Nvidia
In terminal, let's undo what we tried that did not work:
sudo nano /etc/default/grub
Change GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset"
back to
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
Tap ctrl+x to exit, then the y
key to say yes to save, then the enter
key.
Run
sudo update-grub
Now run the following to update Nvidia Drivers:
sudo add-apt-repository ppa:ubuntu-x-swat/updates
sudo apt update && sudo apt full-upgrade
The first command "sudo add-apt-repository ppa:ubuntu-x-swat/updates" didn't work.
It is this repository:
It is up to date and maintained. Are you connected to internet?
Was there a Typo in your CLI command?
Whoopsies I wrote app instead of add sorry about that that's on me.
OK so that's worked should I restart again?
Yep, let's see if it did any good...
Alrighty.
It sadly didn't work.
The only new thing is my hotbar has... Vanished
In terminal, can you run
sudo apt update && sudo ubuntu-drivers install
Open Software & Updates
and move to the "Addityional drivers" tab.
Can you relay what shows up there?
In that list of options, what happens if you click on the 470 (Proprietary tested) driver?
Well let's find out and see
Welp I can tell you for sure that it's not a list to enable and disable so thats off the list.
It should do so... it does on mine.
What Specific Nvidia card are you using?
