Hello,
I'm playing with the experimental version of xserver-xorg-video-ati
(6.7.196-2).
I'm using a big desktop configuration with a LCD computer screen on
the vga output and LCD TV on the DVI output.
I want to use the TV screen to watch films.
When I play a video on the first screen, the video is fine. But I
want to play a video on the second screen, I choose
the 16:9 aspect ratio in gmplayer, the video is shifted to the up of
the screen. It mean I see a black rectangular area on the bottom of
the screen.
Is the problem related to gmplayer or to xserver-xorg-video-ati?
Any ideas are welcomed.
Thanks in advance.
This *sounds* like you're having a problem where the screens have a
different vertical resolution and since X deals with a rectangular
virtual desktop [0] there is dead space above the second screen but
the video output is centered vertically on the virtual desktop not the
resolution of the screen.
You can probably tell mplayer to move things down, or you could get
your second display to center on the virtual desktop using something like
Option "CRT2Position" "LeftOf 176"
in your xorg.conf if you're using MergedFB, instead of 176 you'd use
half the difference in vertical resolution between your primary and
secondary displays.
Good luck and let us know how it goes, if you have more questions post
here but you may want to include more details.
[0] I think this the true irrespective of weather your using MergedFB,
XRandR or Xinorama and probably TwinView
First, I would like to thanks you for your answer.
More details:
You're right, I'm using a non-rectangular configuration: 1280x1024 for
the first screen, 1360x768 for the second screen.
I use a classical xorg.conf except that I add the Virtual keyword
(Virtual 2640 1024).
I activate the second screen with something like:
* xrandr --output DVI-0 --auto
* xrandr --output DVI-0 --mode 1360x768
* xrandr --output DVI-0 --right-of VGA-0
I'm using the latest radeon driver, which support randr 1.2. Before this
version, I was not able to use the second screen, because I could not
specify a modeline for the second screen. There was no "CRT2Modeline"
option...
As far I understand, I think the mergedFB had no sense with randr 1.2.
Correct me if I'm wrong.
The strange thing is that mplayer correctly display films on the second
screen with the predefined aspect. *But* I change the aspect to 16:9,
the display is not good.
I will do more test tonight.
