I would like to install Arch Linux on my Acer TravelMate 5735Z. Sadly, it has a Intel GMA 4500 MHD graphic card. This means, I suffer from Kernel Bug [GM45] black screen at boot (0 backlight?).

When I boot from the installation CD for Arch Linux 2013.10.01, I can see the menu that lets me choose to install arch/boot the installed system (Ubuntu 10.04, I think)/Power off. But when I choose to install Arch, the screen gets black.

In this German article, the author seems to have found a solution for Linux Mint. But he begins with "start LiveCD in compatibility mode". As there is no such thing in the Arch Menu, I thought I had to edit the installation parameters. But when I hit tab, I get some cryptic stuff:

. linux boot/x86_64/vmlinuz archisobasedir=arch archisolabel=ARCH_201310 init
rd=boot/x86_64/archiso.img

I only have WLAN, so I can't try a network installation.

How can I install Arch Linux on this computer?

You need to hit E at the GRUB menu. According to the bug report you linked to, the workaround is to add i915.invert_brightness=1 to your kernel parameters. Scroll down to the kernel line and change it to (emphasis mine):

linux /boot/x86_64/vmlinuz archisobasedir=arch archisolabel=ARCH_201310 initrd=boot/x86_64/archiso.img i915.invert_brightness=1

To make these changes permanent, edit the kernel line of /etc/default/grub and add i915.invert_brightness=1 to the end:

GRUB_CMDLINE_LINUX="[EXISTING VALUES] i915.invert_brightness=1"

To make changes permanent, I've added this to /boot/grub/grub.cfg –  moose Oct 7 '13 at 0:37
    
@moose don't do that. To make it permanent, edit /etc/default/grub and add it to the end GRUB_CMDLINE_LINUX variable. That way, it will persist if you need to run update-grub again. See my updated answer. –  terdon Oct 7 '13 at 0:46
