[SOL]Prevent resolution switch during boot from the installation media

I have a laptop with a somewhat broken graphics card, I think. A while ago I gave a more in depth description of the problem here, if you're interested. The problem seems to be that the graphics card can't support the displays native resolution anymore.

Now I want to install archlinux on it. The problem is, that the boot process switches to the displays native resolution. I would like to prevent that.

I tried to add `vga=ask` to the boot parameters in grub, but that didn't help. It does present me with a selection of resolutions, but the problematic resolution switch happens later in the boot process and is not affected by the vga selection.

The last thing I can see is

> Triggering uevents...

After that, the screen goes dark. I could confirm this behavior on a different laptop; after

> Triggering uevents...

the display switches to a higher resolution.

Again, my question is, how can I prevent the resolution switch from happening? I would like the boot process to continue with the initial resolution.

Use 'nomodeset' on the kernel line.
