I want to change my grub resolution to 1920x1080.
Tried it already, no success
At the grub screen press c to access the console.
Run this command to display supported resolutions
Edit you /etc/default/grub and use the desired resolution as the value of
Save the file and rebuild grub
In have changed it to GRUB_GFXMODE="1920x1080" no success
# The resolution used on graphical terminal # note that you can use only modes which your graphic card supports via VBE # you can see them in real GRUB with the command 'videoinfo' GRUB_GFXMODE=auto
So according to this you need to reboot - show the grub menu - holding shift will usually do - then press c and enter the command
Make a note of the supported modes - exit and boot into your system - edit the gfxmode to the supported resolution - they will be applied from left to right - if the mode is supported.
My resolution is not listed...
You can only use supported resolutions.
If it's not listed you cannot use it - use a supported resolution.
