How to set text mode 132x60, i.e., VESA text mode 268 (010Ch), upon startup from Grub?
by MdAyq from LinuxQuestions.org on (#564NP)
The old way was to add the kernel boot option "vga=780" (as 780=512+268). This option still kinda "works" but is shown as old and deprecated in favour of GRUB options set in /etc/default/grub. So, how to do this using GRUB? Yes, I'd like to have text boot mode with maximal text resolution, which I believe to be 132x60 for my video card.
(Reason: I'd like to maintain as many of log data on the screen as possible beginning from GRUB till starting GUI (GDM+Wayland) without useless clear screens and many mode changes. If the boot process fails for whatever reason, I need to have a possibility to see what preceded the failure point or at least to take a video of it for a later analysis.)
I run dual-boot Debian buster with Windows 10. Debian has the following packages installed: grub-common, grub-efi-amd64, grub-efi-amd64-bin, grub-efi-amd64-signed, grub2-common.
