what version of truecrack are you using? v3.0? can you write the command line 
of truecrack and all the output message?

Here is my command: vostr1@vostr1-Vostro-470:~/Desktop/truecrack/src$ 
./truecrack -t /home/vostr1/Desktop/1char_truecrypt -c 
0123456789abcdefghijklmnopqrstuvwxyz -m 3 -vv

And the output message:
47979   rzz     NO

mmh.. I have the same problem when I use a cheap nvidia board with other 
graphic software run (like Xorg). You can turn off Xorg and run TrueCrack on 
console mode.
If something goes wrong try to define the "Compute capability"(for GTX630 is 
2.1) of your board into src/Makefile.am:
CFLAGS += -gencode arch=compute_21,code=sm_21

I too am experiencing this issue as well. Running Ubuntu 10.04 with CUDA 
toolkit 5.0. Nvidia GTX 470 video card. 
I saw you response above: "I have the same problem when I use a cheap nvidia 
board with other graphic software run (like Xorg). You can turn off Xorg and 
run TrueCrack on console mode." This made me try multiple things. I tried 
switching to console mode (ctrl-alt-F5) and then running truecrack, switching 
to console mode killing GDM and then running truecrack, booting directly into 
to console only mode and running truecrack without letting GDM/Xorg ever 
start(note: must deal with a few permission issues related to /dev/nvidia* -- 
see http://bit.ly/1dvUMlo for more info). Also tried booting directly into to 
console only mode with my Intel integrated graphics as my default display 
device (and no dvi/video cables attached to my GTX 470 at all). NONE of these 
worked and all passwords would show up with the first two letters being "NO". 

Interestingly enough, this was with a wordlist of roughly 700 passwords. If I 
used a different wordlist that had only 3 passwords, all the attempted 
passwords would be spelled correctly in the verbose output - no more 
"NOssword", etc. For whatever reason the bug seems to not be present with low 
password counts. I will do some more testing tomorrow and see what the exact 
cutoff is between it working properly and it changing the first two letters of 
all passwords to "NO".
