    Exclamation [FIX 2] Black screen after startx (BT 5 R2) [2 FIX]

    I tried all the other fixes for the black-screen error, unfortunately they failed.
    Anyway here is way I solved the problem.

    1) Boot live disk normally.
    > Wait till the screen to decide which mode to boot (forensic, safe etc).
    2) Press the TAB key. (This opens the grub options for the live boot)
    3) Change the section with "text splash vga=791" to "text splash vga=791 i915.modeset=1".
    4) Press the ENTER key.
    5) Wait, type startx as usual.
    6) Enjoy the live cd.

    Pros599's post is for a already installed machine, I recognized the similarities. So cheers to him, if this works for you thank him.

    I have NVidia GT520M for reference. Currently doing a full install. Lets hope it works... *doubts*

    Well the expected happened, it didn't work after install. However the problem was fixed by:

    Following Pros599's actual instructions.
    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.

    Then
    apt-get update
    apt-get dist-upgrade
    startx

    I hope this helps everybody out.

    9. Wait
    10. Restart

    Then
    1) Connect to internet via a LAN cable (there is a way to connect to wifi through terminal commands but LAN is easier)
    2) login to root
    3) apt-get update
    4) apt-get dist-upgrade
    5) startx

    I hope this helps everybody out.
