What I mean by that is that on the target machine, start X by just running "X" on the terminal. This should light up both screens but have a black background (as the old greyish mask was removed some time back). Then ssh in and run DISPLAY=:0.1 xterm . If this doesn't work, that means that your second screen (by which I mean X screen btw) is not set up properly. In such a case, please provide your xorg log and xorg.conf. Most people use Zaphod to merge heads from multiple GPUs into a single logical screen with Xinerama. However I believe at least Mario Kleiner has, in the past, tested something more akin to your use-case (and helped diagnose/fix related bugs).</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
