Fix Blackscreen after startx in Backtrack 5

Fix Blackscreen after startx in Backtrack 5 

boot from your live usb and when you come to the first screen where you have different boot options like Text,Forensic,Stealth and so on you want to hit TAB key on your keyboard. Now you should see some text below the boot options find where it says

Code:

text splash vga=791

and replace with

Code:

quiet splash i915.modeset=1 vga=791

then hit enter and log in to Backtrack.

2) Now install Backtrack to your HDD as desired and wait for it to finish, now when it asks to reboot hit yes wait till screen goes black and remove your usb then hold SHIFT key on your keyboard (this must be done before Backtrack boots back up). You should now be in the grub menu now hit E on your keyboard and find whrere it says

Code:

text splash vga=791

as we did before and change to

Code:

quiet splash i915.modeset=1 vga=791

then hit CRTL+X on your keyboard. Now just login with ROOT and TOOR then startx you should now be on the GUI.

3) To make this permanent you need to go applications then accessories then search for files. Next type grub in the name and files in the look in folders part. Scroll down to /ect/default right click and open with gedit then find the line that looks like this

Code:

GRUB_CMD_LINUX_DEFAULT="text splash vga=791"

now replace with

Code:

GRUB_CMD_LINUX_DEFAULT="quiet splash i915.modeset=1 vga=791"

then hit save and close window. Now open a terminal and type

Code:

update-grub

then just reboot and you are done .
