Hello all,
I have a problem with my recently obtained TFT monitor. I don't know if
this is the right place to post (sorry). I want to have it connected to my
laptop and use both screens, the laptop's screen and the external
monitor.
I tried various configurations I found on the web, and up till now I can
do one of the following:
- use *only* the laptop's lcd (at least it worked...)
- use *only* the external tft monitor
- use *both* using the same resolution on both
The problem is that the lcd is a 4:3 (1400x1050) while the TFT is a wide
16:10 (1440x900). Since the 16:10 is not a VESA supported ratio, I
managed to configure correct the wide monitor using ModeLine in
xorg.conf
To use both screens I use MergedFB. I create some "Device" sections in the
xorg.conf that are identical, except the identifier, and some "Screen"
sections, using each device in one of them. I then configure MergedFB in
one of the Screens, and I also enabled MergedXinerama and
MergedNonRectangular.
The wide monitor although that is connected was not detected by the
radeon driver, and I had to force the use of MergedFB. When I used the
Option "MonitorLayout" "LVDS, TMDS"
it was detected *but* not the DDC settings.
The result is that I can get both monitors working with the nice option
to be able to drag windows from one screen to another (I really like
this :) ), *but* the same resolution is used on both, so one of them is
not displaying things good.
Now I saw in some forums that you can use the PanelSize option to
explicitly state the resolution you want to be used in the specific
screen. I used this and alternative the MetaModes but it led nowhere,
But I spent a few days (mainly nights) to get this far... I don't know
if it is possible, but can the radeon driver drive two monitors with the
same card, that they use different resolution? I'm not sure if my
xorg.conf is correct...
I am using FreeBSD-6-Stable, Xorg 7.2, and radeon driver.
Could please some help out, if he/she had the same case solved? I attach
my current xorg.conf stripped down.
Kind regards,
Vassilis
