One of my machines has a 3 TB HD setup to triple boot into Mint 14 (Ubuntu 12.10 variant), Slackware 14.1 and Arch Linux. The HD is formatted using the GPT/Guid system. The Grub2 technically belongs to the Linux Mint install but is used to triple boot all 3 systems. Setting it up about 1 year ago was an extremely painful procedure and required 2-3 days of wrestling with it, and tweaking it, to allow it to recognize the Slackware and Arch installs; it always recognized the Mint Linux install easily.I need to be able to pass VGA/VESA modes to Slackware and Arch. I use Slackware and Arch from the command line and therefore console resolution and font size are important factors.
How Do You Pass VGA/VESA Modes with GRUB2?
