how to make custom backtrack ISO?

[complience]

Hi

There is a known bug with BT5 and Intel graphic cards.
There is a simple fix possible (i'm not sure why its not applied to the general release)
I only use BT5 on a live USB and do not have it installed directly anywhere.
How might I make a ISO containing the fix, so I don't need to manually edit the grub each time I bootup?

1. Boot in to backtrack terminal (Just turn on the computer).
2. Log in to root.
3. type in "vim /etc/default/grub" (no quotes)
4. find a line that looks similar to this: GRUB_CMDLINE_LINUX_DEFAULT="text splash vga=791"
5. Move your cursor on top of the last quote on that line and press the letter 'i' on your keyboard (this turns vim in to inserting mode)
6. Add a space between vga=791 and the quote then type in i915.modeset=1 (The new line should look like this: GRUB_CMDLINE_LINUX_DEFAULT="text splash vga=791 i915.modeset=1")
7. Hit escape on your keyboard and type in ':x' (with out the quotes.. Just hit the keys) and press enter. This will close the editor.
8. In your console type in 'update-grub' (no quotes)
9. Wait
10. Restart
11. ????
12. Log in to root, and type in startx... Profit.

Why not run BackTrack as a Persistent USB? Then all the changes you make will stick.

Hi.. thanks for the idea.
I like your thinking mans solution.. only id rather not use an entire 8gig USB drive just for backtrack.
Still holding out for an ISO fix if at all possible.

im seeing an error when running iso_mod.sh

seeing this error
[*] Setting up the build environment...
mount: according to mtab /home/liminal/Downloads/BT5R3-GNOME-32.iso is already mounted on mod/mnt/ as loop

YOU MUST USE A VALID .ISO FOR THIS SCRIPT

Been trying to follow the tutorial on making a persistent USB
http://www.backtrack-linux.org/wiki/...Persistent_USB

But it talks about copying the ISO and then provides terminal commands for ripping a CD so im confused

Copy the files from the iso to the USB drive
cd /mnt/sdb1
rsync -r /cdrom/* .

figured it out that you need to use DD to get the data out of the iso onto the usb

sudo dd if=~/Downloads/BT5R3-GNOME-32.iso of=/dev/sdb1

but that then corrupts the filesystem and I get this error from syslinux

syslinux /dev/sdb1
syslinux: invalid media signature (not a FAT filesystem?)

try

./iso_mod.sh --help

Hi Snafu777

So i tried running ./iso_mod.sh again and this time worked!
but maybe you didn't read what I wrote.. I can't make a persistent usb with the instructions here.. regardless of whatever ISO i use.
Because I have noway to extract the iso image on the usb without corrupting it.

The iso_mod script is not to make a persistent capable iso for usb's. It's intended to make a modifiable iso. I don't like the idea of persistence so i've never used it. If i see something i like, i add it to my iso, and its there...

It's a handy script if you like to keep yer bt5 iso up to date, but as far as persistence goes, i've no clue how this capability affects it.
