    Grub2 console Resolution

    Hi all,

    Let me premise this with yes I have searched the forums and google but I cannot find a answer to my specific question.

    Previously on my Lenovo s10-2 (1024x600 netbook) I had Ubuntu 9.10 and Backtrack 4.

    Grub 2 was installed with the Ubuntu install and I upgraded the Backtrack install to use Grub2 as well for consistency.

    On the Ubuntu install I added the following to the /etc/default/grub file:
    GRUB_GFXMODE=1024x600x32

    And then added to the /etc/grub/00_header file (in the right spot):
    set gfxpayload=keep

    And ran sudo update-grub.

    I could then boot either Ubuntu 9.10 or Backtrack 4 with a console at 1024x600 with no issues.

    Last week I did a fresh install of Ubuntu 10.04 and did the same as above. Works fine for Ubuntu, but for Backtrack I just get a blank console on boot. It does boot fine, and if I login and type startx it starts x, but if I logout it drops be back to a blank screen.

    I can see that they are running different versions of grub2 - but can;t find much on why this is happening.

    Any suggestions?

    Cheers/

    Thanks for the suggestion dino99.

    I had previously tried 'GRUB_GFXPAYLOAD_LINUX=keep' I added it again to be sure and did the extra step of 'grub-mkconfig' which completed successfully (along with update-grub).

    However no change in behavior.

    Any other suggestions?
