I think you can use video=HxV@refreshrate

This is not documented in ArchWiki yet, and I think it has been a new feature in .31 or .32. For laptop displays, the right resolution should be chosen automatically though.

I saw on arch-announce that xf86-video-intel now only supports KMS, and I wanted to ask: is there still a way to specify the resolution of virtual consoles, like we used to do with vga=XXX in kernel options?

vga=<INPUT>:<RESOLUTION>

Thank you, just what I needed! It was in the commit log from Damien's link too. I tried it, and it works. As Thomas said, the right mode is chosen automatically on a laptop, but sometimes I might need to set it on an external device such as a beamer (overhead projector), or I might need a 80x24 console even on my laptop screen. Now, more questions: - Is there extensive documentation about that somewhere? - Is there a way to enforce an aspect ratio, eg. to have a 4:3 mode with black stripes on the sides on a 16:10 strip? - Is there a way to change the mode on the fly without rebooting? I will edit the Arch wiki once I get answer to those. -- catwell

I haven't tested it but you can try "fbset"

- Is there a way to enforce an aspect ratio, eg. to have a 4:3 mode with black stripes on the sides on a 16:10 strip?

I'm not sure about this, maybe if you set a lower 4:3 resolution on your 16:10 screen AND in the BIOS of your laptop it's setup to NOT scale the screen it will show the black stripes. -- damjan
