A while back, I installed Backtrack 5 R2 to Dual Boot on a Windows 7 PC. It worked fine for a while, but now when I try to load it, the screen gets all messed up (tried to get a picture with my phone, but it wasn't working too well). The last line before it freezes says:

fb: conflicting fb hw usage: nouveaufb vs VESA VGA - removing generic driver

Since it last worked, the only changes I can think of are that the computer is now connected via the ethernet cable to the router, and I upgraded the graphics card (to Nvidia). Because of the last line, I personally would put my money on the latter, but I still have no clue how to fix this. Can someone help me?

Not that it helps your current situation, but there are newer versions that might be work looking at, namely Backtrack 5 R3 and Kali. – spuder Aug 15 '13 at 6:02

Indeed you're having problems with your new graphics card. Your system is trying to load the driver called nouveau, but it is not working. Because of the fb, I think this error happens in the early stages of the boot process.

You should try to install the driver delivered by Nvidia itself.

To do so, you could try these instructions (the second post of that thread would be useful to you).

Update: I copy below those instructions. They were written in that forum by user maverik35, on April 09th, 2011.

  • Enter the safe mode or text mode.
  • Uninstall the nouveau driver.
  • Blacklist it
    • In /etc/modprobe.d/blacklist.conf, just type blacklist nouveau in a new line.
  • Install the nvidia driver (previously downloaded from nvidia website and according to your card model), just follow the instructions.
  • Load these changes. You have two different ways to do so:
    • Startx the X's (startx)
      • If you startx and see some problems, you might want to do this:

        modprobe -r nouveau
        modprobe nvidia.

    • Just reboot (reboot) at prompt.
      • At startup, it will load all sistem with new nvidia driver.

This might seem like a stupid question, but how do I get into safe mode? When the computer first boots up, I have the option of "recovery mode" and then the regular OS. I gave recovery mode a shot, but it fails too. – dstars5 Dec 7 '12 at 22:11
You can use the install CD. It should give you the option safe mode. – nozimica Dec 9 '12 at 0:57
But it is already installed on my computer? Will the install cd do anything for me? – dstars5 Dec 9 '12 at 1:07
Read carefully this link: hackingdna.com/2012/02/…. – nozimica Dec 9 '12 at 2:10
Ok, so I did the Backtrack Debug - Safe Mode, but it still just froze – dstars5 Dec 9 '12 at 2:33
