    Thanks for any help in sorting this out.
    EXACT same problem. Has anyone come up with a solution to this?

    ok. This was a total waste of time

    I am running Acer Aspire 4257Z with Intel@ HD Graphics

    This is how I did it

    1. Installed BT5R1
    2. rebooted
    3. apt-get update
    4. apt-get dist-upgrade

    rebooted

    1. Boot in to backtrack terminal (Just turn on the computer).
    2. Log in to root.
    3. type in "vim /etc/default/grub" (no quotes)
    4. find a line that looks similar to this: GRUB_CMDLINE_LINUX_DEFAULT="text splash vga=791"
    5. Move your cursor on top of the last quote on that line and press the letter 'i' on your keyboard (this turns vim in to inserting mode)
    6. Add a space between vga=791 and the quote then type in i915.modeset=1 (The new line should look like this: GRUB_CMDLINE_LINUX_DEFAULT="text splash vga=791 i915.modeset=1")
    7. Hit escape on your keyboard and type in ':x' (with out the quotes.. Just hit the keys) and press enter. This will close the editor.
    8. In your console type in 'update-grub' (no quotes)
    9. Wait
    10. Restart
    11. ????
    12. Log in to root, and type in startx... Profit.
    To the line

    but after point 12, the screen goes black as allways.

    I have enjoyed Backtrack since before version 3 and I have never had any form of issues with it up to version 5
    Sad to say, but if this cannot be fixed, why bother using it at all.
    Missunderstand me correctly, I want to use it, i love to use it, I need to use it, but as of now, I cannot use it at all, and I do hate to
    be the one that installes backtrack 4 just to be rocking backtrack, I feel that is a shamefull to the backtrack team.

    So please, this is an down to my knees all out begging, please fix this issue so that I can finally use the version 5

    PS.

    Same issue with

    BT5R2 Gnome/KDE 32/64bit
    BT5R1 Gnome/KDE 32/64bit

    Both are not working after upgrading to latest kernel (i.e doing the apt-get dist-upgrade)

    BT5R1 works fine out of the box (until dist-upgrade) BT5R2 does not work at all after install, reboot then startx (black screen of death)


    So please rename this thread to (NOTFIXED)

    you will be able to edit the boot configuration, where you see text splash nomodeset change it to text splash i915.modeset=1 and then press ctrl+x to boot, you should boot without problems

    After that, edit the file /boot/grub.cfg and do the same thing

    Hope it helps
    Many thanks, fixed my lenovo t410s with Intel Integrated Graphics (rev 02)

    Is there a version of the backtrack ISO with this fixed as default?
    for Live CDs and whatnot - fedup of fixing the grub each time
