1280 x 800 resolution in GRUB?

Hey, I've gotten Arch installed on my new Inspiron 13, which has a widescreen display. The only issue I've encountered is that I can't seem to find out how to get a 1280 x 800 resolution in GRUB. I know for 1024x768, the VGA is 773. Can anyone help me figure out what to put for 1280x800? Thanks!

Anyone Correct me If I'm wrong. But I think this is being developed. You could do a google search for "Widescreen resolution framebuffer linux". There's an Arch post there.

standard vesa framebuffer can't do this. you will need either uvesafb or a certain hardware related fb driver like radeonfb depending on your graphic card.

I've found somewhere on the net that it should be vga=952, but I'm not sure if it'll work.

Check /boot/grub/menu.lst to see what available modes you have (the comments should still there if you didn't manually remove them from the file)
I think the vga=952 is a ubuntu thing that works only with usplash...the Ubuntu "splash screen".

[edit] Hm apparently Suse 10.2 had that too...

Where did you get hwinfo package atasmrk? The one in AUR is flagged outdated...

That should be 1440x900, http://en.wikipedia.org/wiki/VESA_BIOS_ … de_numbers

Edit: Sorry I missed the subnote, it seems it selects 1280x800 8-bit on some laptops.

You need to install an RTFM interface.

Re: 1280 x 800 resolution in GRUB?

thanks moljac, 864 works on 1280x800 here with nvidia

edit: 0x361(865) is also the highest one displayed by grub in the selection which it suggests is 1280x800x32 and this works now.
