Is tv overscan possible in dual head configuration??

[daveywilks]

Hello all,

I am running the latest proprietary ATI linux drivers(8.31.5) on ubuntu edgy.
I have set up in dual head mode so i can put videos on the TV for my G/F while still using the computer for my important stuff.

This setup is working fine except that i can't seem to enable overscan on the tv-out in dual head mode. i can do it in clone and big desktop!

here is a snippet of my xorg.conf

When i do
aticonfig --tv-info

i get
The TV is not connected
The TV geometry is "100x100+0+0"
The horizontal position limits are [0, 146571128]
The vertical position limits are [147396624, 146486216]
TV overscan mode is enabled

But the tv is definitly connected(eg. i have an instance of x running on it and i can see it!) and the overscan is definitly not enabled!!!!!

Any gurus out there know if this is possible/how to do it???

Cheers

Does overscan work if you enable the second display dynamically with aticonfig using the DDM options?

[daveywilks]

Thanks for the help,

Tried that, got this

root@edgy-eft:/home/dave# aticonfig --enable-monitor=tmds1,tv
ati_dm: FGLRX_EnableDisplays failed when try to enable display: c.
Using /etc/X11/xorg.conf
Saved back-up to /etc/X11/xorg.conf.fglrx-24
root@edgy-eft:/home/dave# aticonfig aticonfig --query-monitor
Connected monitors: tv, tmds1
Enabled monitors: tv, tmds1
Warning : Option 'QueryMonitor' is exclusive, other options will be ignored.
root@edgy-eft:/home/dave#


It didn't seem to work but i can't mess with it at the moment as my g/f is home and is watching tv :rolleyes:

I'll try some more experimentation tomorrow.

Had you tried using the dynamic options when using a "simple" configuration (e.g. aticonfig --initial and then enabling overscan)?

[daveywilks]

I'll give that a go tomorrow, stay tuned for more updates:)

My conf. works ok. (overscan included) http://www.phoronix.net/forums/showpost.php?p=2721&postcount=7
after initial configuration, you enable overscan. With edgy and 8.31.5 it works better if you
sudo -i and then
cd /etc/X11/
aticonfig [options] instead of
sudo aticonfig [options] from your current directory.

Why would you want overscan on dual-head since you wouldn't see the panels to control the second monitor?

Thanks for the replies guys, I'll probably have to try these on the weekend now as my g/f's work schedule means that she'll be monopolising said television until the weekend :mad:

Thanks

Dave
