Font Sizes and Grub Stuff

And overall look are easy enough to change with different desktop themes.

In order to fix dual booting I had to add a stanza to OS12's /boot/grub/menu.lst. Below is a what the last two stanzas look like now.

###Don't change this comment - YaST2 identifier: Original name: linux###
title Desktop -- openSUSE 12.1 - 3.1.9-1.4
root (hd0,2)
kernel /boot/vmlinuz-3.1.9-1.4-desktop root=/dev/disk/by-id/ata-ST3500418AS_9VMRL8BM-part3 resume=/dev/disk/by-id/ata-ST3500418AS_9VMRL8BM-part7 splash=silent quiet showopts vga=0x31a
initrd /boot/initrd-3.1.9-1.4-desktop

###By me to dual boot to LinuxMint12
title LinuxMint12
root (hd0,0)
kernel /boot/vmlinuz-3.0.0-15-generic root=UUID=3f531261-e31c-4b42-bc95-933458c5d59c
initrd /boot/initrd.img-3.0.0-15-generic

Using the syntax that works for OS12 doesn't work for LinuxMint. Specifically the "/dev/disk/by-id/STRING-part1" part. Also using the LM symbolic links in / didn't work.

mark@flounder:/media/3f531261-e31c-4b42-bc95-933458c5d59c> ll vmlinuz
lrwxrwxrwx 1 root root 29 Feb 19 23:33 vmlinuz -> boot/vmlinuz-3.0.0-16-generic

mark@flounder:/media/3f531261-e31c-4b42-bc95-933458c5d59c> ll initrd.img
lrwxrwxrwx 1 root root 33 Feb 19 23:33 initrd.img -> /boot/initrd.img-3.0.0-16-generic

Do you see the subtle difference in the path in the symbolic links?

This means that I have to edit OS12's /boot/grub/menu.lst every time there is a new kernel for LM. I use Gvim to do that task.

The two sentences marked in red above are wrong! I think the first time I tried using the LM sym links I had the hd value for grub set incorrectly. I edited OS12's /boot/grub/menu.lst last night to read as follows: (Note I'm currently running LM booted from this change.)

###By me to dual boot to LinuxMint12
title LinuxMint12
root (hd0,0)
kernel /boot/vmlinuz-3.0.0-16-generic root=UUID=3f531261-e31c-4b42-bc95-933458c5d59c
initrd /boot/initrd.img-3.0.0-16-generic

### By me testing using the sym links in LM's /
title LinuxMint12T
root (hd0,0)
kernel /vmlinuz root=UUID=3f531261-e31c-4b42-bc95-933458c5d59c
initrd /initrd.img

I now have two entries for LinuxMint. Technically I could edit that file on the Opensuse partition and comment out the stanza I don't need but I think that might be risky.

The sheet components are successively ready by chopping, joined together and, for example, accomplished by cut-outs or weldons. The laser-cut sheet Glass Teapots with Infuser metal elements are positioned in sandwich configuration after which welded by the laser beam. CNC manufacturing and metal fabrication each play a big function in creating and designing cutting-edge components and methods. One of the most important issues to consider about|to contemplate} when choosing between the 2 processes is the complexity of the design and its material. Sheet metal fabrication is nice for advanced designs and repeating shapes and patterns, however CNC manufacturing is healthier for classy curves and contours.
