Ubuntu 10.10 and HDMI screen resolution
So I just installed Ubuntu 10.10 on a computer attached to my TV.

I have an issue.
If it is connected via HDMI the the desktop area is 1920x1080...
the top and bottom task bars are not displayed on screen but i know they are there because i can click on top left corner to get the menu.

If I use the VGA cables, I can see the entire thing(the top and bottom task bars are there)

Can anyone help me this issue?

The panels, you mean? Probably because you have multiple monitors hooked up. Try hooking the Ubuntu box up to the TV and *ONLY* the TV and see what happens.

Okay I had both the VGA and the HDMI connected to the TV.
I just took VGA cable off the computer and did a good ol' fashion reboot
still the same issue with the HDMI cables.

I would just like to say
OMG the picture/color quality with the HDMI cable is so much better.
Must find a way to use this.

Did 10.04 do the same thing when connected to HDMI?

Never tried 10.04 on this system.
10.10 is the first OS that this system has

I had another system running FC13 but that doesnt have an HDMI output....

Did it have Windows before? If so, and Windows worked, it's definitely a problem.

Of course, here's what I think is wrong: I think that there ARE panels, but that they're off the edge of the screen. In that case, try a different resolution, like, say, 720P instead of 1080P.

Nope never had windows on it before.
Ubuntu 10.10 is the only OS thats ever been on this machine.
I just built it a few days ago.

And yes there are panels.
But they are off screen.
I know they are there because I can click at the top and the menu will come down.

Okay, what video card did you use? Like I said before: Try 720P and see if it works.

Same exact problem, but I can say mine did it also with 10.04, so I uninstalled it and went back to Windows XP (fresh install there also).

I would like to ditch Windows XP, where it worked fine on the HDMI. Would love to make Ubuntu 10.10 my media center operating system, but it seems the screen is just a tad large and truncates all 4 edges just a bit (enough that the menus are not visible).

As with the original poster, you can click in upper left corner off the screen and then you can see the resulting menus.

Will post more info when I get more details, like video card and if the same happens at 720p.

I had a similar problem with Debian testing and a Samsung SyncMaster 2494HM when using HDMI (previous use with a VGA cable with no problem): at 1920x1080 the screen was truncated and the picture was not completely neat.

In fact, the problem was neither nor Linux but the Samsung display itself. For a reason I ignore, two options were checked in the screen configuration (that can be changed thanks to the OSD menus and the buttons on the screen):
- A/V mode was ON, I disabled it and the picture became very neat and nice
- Image Size > Scan adjust was ON, I disabled it and then the picture correctly fitted the screen

Hoping this will help

Yeah, like I said, try 720P instead of 1080P. As far as I can tell, the higher resolution may be shoving the panels off the screen.
