1280x800 Framebuffer on Acer Travelmate

Hi there

I have an Acer TravelMate 4314 where the native resolution is 1280x800
and I'm just wondering how can I make the framebuffer show that resolution?
I know there's a "hack" for intel 915 but my lapto has a Radeon Xpress 200M.
Anyone know how to do this? Google only turned up 915 :S

Thanks in advance

1. install the lrmi  package, and run vbetest as root, and you can see if your screen support 1280x800;

2. if it doesn't support the resolution, and if you have an intel graphic card, you can turn on KMS (Kernel Modeset). See HOWTO: Enable KMS.

Just ran it, doesn't look like it supports it. (It doesn't show up?) But that's the resolution I've always run with :S

I don't have an intel card It's a radeon

you can allways build a custom kernel + a few patches from fedora and you'll have KMS on radeon.

I also have a Radeon Xpress 200M in my laptop and recently discovered radeonfb.

Just put radeonfb in the Modules array in /etc/mkinitcpio.conf
MODULES="radeonfb"
and run
mkinitcpio -p kernel26
to regenerate your kernel image, don't forget to remove all previous framebuffer stuff from grub.
radeonfb will use the highest possible resolution automatically.

Works fine on my system.

You could also achieve the same effect by using uvesafb.

If all else fails you could try vga=865 at the end of your kernel line in your grub config for a 1280x800 framebuffer at 32-bit.
