Fail to setup GRUB2 framebuffer resolution with fglrx

I've got ATI Mobility Radeon HD 3650 on my laptop, i use fglrx and i got ugly resolution in grub until i will fix this. I did it before on arch and ubuntu - with Uvesafb but as for now i can't setup it.

So my steps are:

• pacman -S v86d

• add v86d to the hook array

• add this

  options uvesafb mode_option=1024x768-24 mtrr=3 scroll=ywrap

      to

  /etc/modprobe.d/uvesafb.conf

• regenerate initramfs image

• modify

  /etc/default/grub

  like this:
     

  GRUB_CMDLINE_LINUX="quiet splash nomodeset video=uvesafb:mode_option=1024x768-24,mtrr=3,scroll=ywrap"
  GRUB_GFXMODE=1280x800x32,1280x800x24,1024x768x32,1024x768x24 

               comment this below to keep tty in normal resolution

  GRUB_GFXPAYLOAD_LINUX=keep

   
And nothing happens i can't understand what's the problem here -.- Thank you for help and support.

Re: Fail to setup GRUB2 framebuffer resolution with fglrx

/etc/default/grub:

GRUB_GFXMODE=1024x768x32
GRUB_GFXPAYLOAD_LINUX=keep

To generate the changes, run:

grub-mkconfig -o /boot/grub/grub.cfg

If that doesn't work try replacing

gfxmode="1024x768x32"

with

vbemode="0x105"
