Having installed GRUB as boot manager allows the operating system (Linux) to boot on specific video mode so the TTY virtual consoles change its columns and rows (width and height).
For example, editing
/etc/default/grub (for GRUB v2) :
But now I have an embedded Linux device: Utilite Pro from CompuLab, and I am testing Ubuntu 12.04 and Kali Linux v1.1.1 for it.
They both work OK, but seem not to use GRUB as boot loader. According to the docs, they use U-Boot as boot manager.
Could I do this resolution change for virtual consoles (TTY, text mode) for U-Boot?
I don't need to change the GUI video resolution, yet I can accept to change it too if it is needed.
