    Default Remote GUI?

    Hi,

    I am new to linux as well as backtrack, so I'm slowly feeling my way. I have installed backtrack

    on a stand alone server (HDD install) and it works fine. startx opens the GUI and all is good.

    However, i want to rack mount the server and remove the attached display and keyboard. So, i have

    setup ssh on backtrack and can connect remotely from a windows XP box using putty. All well and

    good, but i would like to use the backtrack GUI, so i have installed Cygwin/x on the windows box,

    ticked the x11 setting in putty and connected and log in. i type xterm in putty and the popup box

    opens with the backtrack command line prompt, i type startx and get the following error;

    root@bt:~# startx

    (EE) MACH64(0): [dri] DRIScreenInit Failed

    From looking around the Internet, mach64 seems to refer to a display error. The backtrack server

    and windows box work fine in terms of display individually, so would i be correct that this error refers to backtrack being unable to drive the windows graphics?

    So, can anyone suggest how i should proceed from here. Do i need to manually configure a file in

    backtrack to make this work and if so, what file and what do i need to edit?

    I am so close to getting this working, any help would be massively appreciated.

    Cheers,

    Syndy.

    Hi,

    I just noticed that the log has not copied correctly, some spurious # marks have appeared.

    The log should be as follows;

    Someone just posted about X11 forwarding in the video section. here is the link to the blog post.

    http://j2neon.blogspot.com/2011/05/s...tp-in-bt5.html

    Personally I use x11vnc.
    Here is a tut I did on the old forum
    http://www.backtrack-linux.org/forum...-over-ssh.html

    x11vnc is a bit different than the above tut. VNC sessions generally start their own X11 screen whereas x11vnc ties the vnc session to the currently running screen. Either one isn't too hard to figure out, just don't use VNC without SSH tunneling over the internet. On your LAN is probably fine though(VNC sends credentials in clear text like telnet or ftp)
