framebuffer and display resolution

hi,
I have an onboard graphiccard with an Intel 945GME chipset. My display allows a resolution of 1024x600 pixel. But how do I find out which is the correct value for 1024x600 to setup the correct vga value in my /boot/grub/menu.lst to activate the framebuffer and show those nice archlinux-logos while booting? It seems it always just gets a 800x600 resolution and a bad color-depth.

Re: framebuffer and display resolution

Hi,
Profjim I already tried hwinfo before I posted but the version  in the AUR doesn't work with 2.6.27 and if I compile a newer version there's no output with --framebuffer. Is there any other way or application which can give me this information? Or can I even calculate the needed value by myself?

Re: framebuffer and display resolution

I guess you have to use uvesafb for allowing such resolution.

Hmmm, well you could look into the hwinfo docs and see whether there's some compile-time option you need to supply to make --framebuffer work. (It could be that the functionality is now gone, but maybe it isn't.)

If that doesn't lead anywhere, you could try this (annoying amount of work but you'd only need to do it once): install a minimal Arch on a fresh partition or USB key, don't update the kernel to 2.6.27, and compile/run the hwinfo that's on AUR.

uvesafb really rocks! Through it I set up my 20 inch Philips LCD showing 1680x1050 correctly when attached to my X41.

Re: framebuffer and display resolution

Okay I found this method now in the wiki to check what's possbile: http://wiki.archlinux.org/index.php/GRU … ant_to_use and all I got was 800x600. So it seems I really need uvesafb.

Thanks for your help!
