Error in cuda-gdb under ubuntu 11.04

Hi everybody,

I’m trying debug the sample aplicattion of the cuda-gdb user manual. Before debug, I stop de gnome display manager with sudo service gdm stop. You can see the error in the attached file. I get the same error when I execute any program with the gdm stopped.

Basicly, the error consists the character of the screen are ilegible.

Any ideas? Thanks a lot guys!
