Here’s another problem I’ve encountered while trying to run the X window manager of the popular security centric distro of Linux, the Backtrack 4. These were the errors I got when I tried to run the “startx” command.


no screens found
(EE) No drivers available
(EE) FBDEV(0): FBIOBLANK: Invalid argument


The above errors can simply be fixed using either of the command which does basically the same thing.

fixvesa

or

copy /etc/X11/xorg.conf-vesa to /etc/X11/xorg.conf

After invoking any of the commands above, you can now run the “startx” command to spawn the X window system.
