I'm a linux noob here. My dad asked me to change my old laptop's OS, so I landed on Zorin OS. At first after installation I got a black screen, then I searched for answers and followed [SOLVED] Black screen after install .
Now I got a new problem, I can't change resolution of my screen. I've tried to change using xrandr, but there's an error saying
xrandr: Failed to get size of gamma for output default.
I've been stuck with this for 5 days, I hope anyone can help me to solve this issue, thanks.
Resolution is stuck at 800x1280 77hz
(default 1280x800 60hz)
Can you please boot to Grub Menu, then arrow key to boot with Recovery...
First thing in the Recovery menu to do is to enable networking.
Once enabled, back up to the recovery menu and arrow key down to Drop to Prompt.
Tap Enter key or ctrl+d, then open your grub file
sudo nano /etc/default/grub
Remove the nomodeset parameter and restore the line parameters to just "quiet spalsh"
Ctrl+x to exit, then the y key, then the enter key.
With that done, still in the terminal prompt, please run:
Yes, if you do not see the grub menu at boot, you can tap the esc or tab key if using EFI or EFI /GPT boot. Or hold the Left Shift key if using Legacy (MBR) boot.
This should pull up the Grub Boot menu.
To enable networking is as easy as it sounds - which makes a lot more sense once you experience it. In the recovery menu, one of the listed options is "Enable Networking." Selecting it asks if you want net enabled, you say "yes"... and it is enabled.
