Update (2026): BackTrack 5 đã ngừng phát triển từ lâu; người kế nhiệm là Kali Linux (cũng có thể dùng Parrot OS). Chỉ nên xem bài này như ghi chép lịch sử.

Cài đặt BackTrack 5 bị treo (màn hình đen) sau khi chạy startx.

I encountered this problem while installing BackTrack 5 R3 from a USB stick (multiboot). I googled it and found some help, but in the end I had to fix it myself.

If you have already tried the following and it did not work:

1. Edit the file /etc/default/grub.
2. Find the line: GRUB_CMDLINE_LINUX_DEFAULT="text splash nomodeset vga=791"
3. Change it to: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i915.modeset=1 vga=791"
4. Save and close the file.
5. Run update-grub to refresh GRUB.
6. Reboot.

I guess you got stuck at step 5 and could not update GRUB.

At the boot menu, move the cursor to the top entry (BackTrack Text) and press TAB to edit it. A command line appears; replace

text splash nomodeset vga=791

with

quiet splash i915.modeset=1 vga=791

Press ENTER and you are all set.

Just remember: after the installation finishes, edit /etc/default/grub, run update-grub, then startx.

By the way, the default password for root is toor.
