Hello guys,

in rare occasions I need remote access to my computer from my smartphone.
I am able to connect to my router via VPN and use its Wakeonlan abilitie. This starts the computer up to the point where KDM is showing the login panel.
At this point I am not able to VNC to the computer, since VNC requires the VNC-Server to be started wich is obviously the case only if I am logged in to KDE, which I can not because I have no access at this point in time. I use kfrb for this purpose.
One solution could be to SSH to the machine and start KDE and than change to VNC-Connection. The problem is, I cannot start KDE from the terminal (neither with startkde "$DISPLAY not set or cannot connect to X-server" nor startx "command not found"). Also I feel this solution to be not very elegant.
Are there other ways I am not aware?

Thanks for your help

System: debian wheezy and KDE 4.8.4

Assuming your computer is starting from a cold state rather than sleep, you could configure it to automatically login and lock.
Alternately, you could setup an VNC server to connect directly to X from login, or setup Xvnc - although this could give a degraded KDE experience.
