Slackware Console Resolution when Dual Booting with Another Distro's GRUB2?
I am tweaking my new Linux Installs on a new home-built machine. I installed Linux Mint 14 first followed by Slackware 14 and Arch Linux on separate partitions. I don't think it matters, but the machine (AMD A10 CPU with a A75 chipset MSI motherboard) is UEFI (and secure boot) capable but I am running it in Legacy BIOS mode, since I have not wrapped my brain around this whole UEFI thing. The 3TB hard drive is however partitioned using a GUID partition scheme (without an EFI partiton), though none of the partitions is greater than 2 TB (the largest partition on that drive is 1 TB). I have already spent a couple of evenings tweaking the installs and would rather leave them as is.
After wrestling with it several times, I have managed to get os-prober and GRUB2 to recognize the existance of the Slackware and Arch Linux partitons and to boot them correctly. The auto-genetated /boot/grub/grub.cfg file is a fairly elaborate (and frightening) affair with elaborate shell scripting including if-else scripts etc. It is beyond my level of comfort with editing GRUB and LILO config files (I can handle manual editing of a simple LILO or Legacy GRUB script).
After this lengthy introduction my question is this:
I intend to use Slackware and Arch mainly from the command line. The console font and resolution on my 24 inch screen is a low resolution chunky affair and I would prefer to adjust the console resolution. I know how to do it to some extent using LILO in Slackware (even then it is a little unpredictable) but am now relying on Linux Mint's GRUB2 as the boot loader for the 3 distros (will also add Scientific Linux later).
How do I adjust the console resolution for Slackware and Arch (preferably independently) within GRUB2 installed from within Linux Mint?
