HDMI TV/monitor not showing up on Ubuntu Dell Mini 10


Hey, I'm running Ubuntu 10.04 on a Dell Mini 10 (GMA 500/Poulsbo chipset) and I can't use the HDMI port.

I have an HDMI TV/monitor that I'm trying to plug in (it has an HDMI1 and an HDMI2 input). Neither the laptop nor the TV can 'see' the other. The TV shows "no input" on both channels and the laptop can't find any extra screens in the Monitor options under System.

The screen/monitor function key switch doesn't affect it. "xrandr" in the terminal only shows one 800x600 (which I assume is the laptop LCD). Please help me diagnose this. (Also, please type out terminal commands in suggestions. I'm pretty n00b when it comes to command line.)

Is not so that you have to switch on the TV set between the two ports ?
Because if you do not do so , there no input on the HDMI port

Yes, I have switched between the two. It doesn't make any difference.

Can you check another HDMI cable? Show the output of:
Code:
xrandr --verbose

that last feller must have figured out his problem, but I would like to pick up where he left off because I have the exact same problem.

Check if you get picture on the TV after:
Code:
xrandr --output DFP1 --primary --same-as LVDS
Also write how long is your HDMI cable and which driver are you using, proprietary or open source?

thanks eSelix, it just started working. I think it was because I added medibuntu to the repositories and I also upgraded the ATI driver software, there was a guide I just installed and updated a bunch of stuff so who knows what did the trick. It was on a newly installed system. What do you think? Thanks again for your reply!
