I have a 15.6-inch laptop with a UHD display (with resolution 3840 x 2160), which is a HiDPI.
282.42 PPI = Actually, an eXtra High density display according to this calculator.
Linux Mint 19 Cinnamon 64-bit. UEFI installation.
I dual-boot with Windows 10 on a separate drive and choose via Grub2 what I need at that moment.
The Grub2 is by default on my hardware set to be displayed in full resolution of 3840 x 2160.
This is incredibly hard to read, practically impossible to do any other thing than press Enter.
I would like to set some lower resolution like 1920 x 1080 or lower depending on what would be readable.
I looked at the comments of
/etc/default/grub file, stating, excerpt:
# 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 `vbeinfo' #GRUB_GFXMODE=640x480
I simply uncommented the
GRUB_GFXMODE line and set it to
sudo update-grub I tested with the result being unchanged resolution.
So, I put hopes in the
vbeinfo command, which was not recognized by my Grub2.
What am I doing wrong here?
And how do I discover all of the supported resolutions?
