When I connect the HDMI cable to the living room TV, my system comes up with the Raspberry Pi desktop, but without LXDE running. I've tried to start it by running the monitor and issuing a "startx" command, but this is what I get in a pop-up window:
At that point I'm stumped. The living room TV is also a Visio HDMI, so I'd think it would be quite similar to the one I normally connect to. I know it can handle the video output, else I wouldn't see the raspberry on the desktop. Could someone kindly give me an idea how to proceed from that point? I originally posted a thread about this issue in the Troubleshooting forum, but got no response.
