OK, I have found why It wasn't working. I had put wrong parameters for
my TV Monitor (HorizSync 31.0 - 50.0 and VertRefresh 60), that's why the
driver couldn't find any mode matching between TV Monitor Config and TV
Output. I have commented this two lines and now it works on the 2
Outputs. Now, I need to find how to fix Modes for VGA and TV Output with
xorg.conf (with xrandr, I can) , because the 2 initial modes are
différents, and my Video in FullScreen (DVD with xine) is cut down on
the smallest mode.
thanks for your help ;)

Dear Frederic
To be honest I had the same problem with TMDS and VGA outputs. The only
other thing I can sudgest is to use PreferredMode option. Although you
might notice that according to log files it is not used but in reality
it does make a difference. Mind you on Ubuntu 7.04 after adding this
option my Xserver crashed and the only way out was to reboot the board.
When I was using Kubuntu 7.10 it worked fine. I also noticed that KDE
doesn't always work properly with dual screen and intel driver. Although
KDM starts fine with both screens enabled and configured individually,
as soon as KDE start the second monitor is turned off and KDE continues
working in a single screen mode. I can switch everything back into dual
mode using xrandr utility but it's a pain in a bum. I wonder if there is
a config script for KDE which you could ammend in order to force dual
screen in KDE.
BR,
Dmitry

Hi Dmitry and all others,
I disabled DDC in "Device" Section but I still can't fix any mode
neither for my VGA (LCD) monitor nor for my TV output. If I disable DDC
, my VGA monitor has "1024x768" mode, if I enable DDC, it has
"1280x1024" mode, Even if I configure any modeline in (VGA) "Monitor"
section, or if I configure anu "Modes" in SubSection "Display".
I tested xrandr, and I can change my mode with this binary (only on VGA
output, I can't fix any mode for TV output, It does'nt work) but I
prefer fix my mode into xorg.conf.
Any other idea ? I suppose it's possible because TV output and VGA
output worked already together.
Thanks again :)
F. MAZUR.

Dear Frederic
Try disabling DDC in drivers section when playing with modelines. Also
check check you config file by justy using Xorg - config <your config
file>. It would save you some time. I had simmilar problem to yours when
I was playing with Kubuntu gutsy one VGA and one TMDS output. For some
reason when I started KDE TMDS output would be on but VGA would be
turned off. I managed to turn it back on using xranrd. For example
xranrd --output VGA --size 1024x768. Also there is crtc option which I
think specifies the pipe the output should be connectd to. So if the
first command does not bring you TV up try adding crtc=1 or crtc=0.

I tried this, and it works better. I had not seen this last line in
intellinuxgraphics documentation. Now, when I configure monitor-LVDS
with option "ignore" to "true" , LVDS output is well disabled, but I
have now these lines in Xorg.log :
(II) intel(0): Output VGA connected
(II) intel(0): Output TV connected
(II) intel(0): Output VGA using initial mode 1280x1024
(II) intel(0): Output TV enabled but has no modes
and further
(II) intel(0): Output configuration:
(II) intel(0): Pipe A is on
(II) intel(0): Display plane A is now enabled and connected to pipe A
(II) intel(0): Pipe B is off
(II) intel(0): Display plane B is now disabled and connected to pipe B
(II) intel(0): Output VGA is connected to pipe A
(II) intel(0): Output TV is connected to pipe none
I probably suppose that if Output TV has no modes, the driver
automatically puts Output TV to pipe none (= no pipe), and if I want the
driver puts Output TV on pipe B, I have to configure a mode for my TV
output.
But there's a problem : Whatever any mode I configure for any Output,
It doesn't change anything. Output VGA still stays in 1280x1024, even
if I configure with the following lines :
Section "Screen"
Identifier "Screen0"
Device "Card0"
DefaultDepth 24
SubSection "Display"
depth 24
modes "800x600" (or "1024x768", "640x480")
EndSubSection
EndSection
The only way I found is to force lower Refresh Values on VGAMonitor
configuration.
And concerning TV Output, I didn't find how to select a mode for it.
Whatever the configuration which I test, I still remain on "(II)
intel(0): Output TV enabled but has no modes".
Thank you for your fast answer anyway :)

Dear Frederic
If you are using intel driver then you need to follow this manual
http://www.intellinuxgraphics.org/dualhead.html. In order to disable
LVDS so it does not get a pipe assigned to it, you would need to specify
Option "monitor-LVDS" "LVDSMon" in device section and create monitor
section with LVDSMon identifier. Within the section you need to specify
option "Ïgnore" set to "true". You might also need to set option
"Enable" to "false" if the first option does not work.

Hi,
I have some problems configuring my Xorg Server with 945HM graphic
chipset. I compiled Xorg 7.3 version and I didn't succeed in making
simultaneously CRT Output and TV Output. Only CRT, or Only TV works
independently. I tried some options ,described in the documentation on
the web site <http://www.intellinuxgraphics.org>
www.intellinuxgraphics.org , like "MonitorLayout" :
(Option "MonitorLayout" "anystr"Allow different monitor configurations.
e.g. "CRT,LFP" will configure a CRT on Pipe A and an LFP on Pipe B.
Regardless of the primary heads' pipe it is always configured as
"<PIPEA>,<PIPEB>". Additionally you can add different configurations
such as "CRT+DFP,LFP" which would put a digital flat panel and a CRT on
pipe A, and a local flat panel on pipe B.For single pipe configurations
you can just specify the monitors typeson Pipe A, such as "CRT+DFP"
which will enable the CRT and DFPon Pipe A.Valid monitors are CRT, LFP,
DFP, TV, CRT2, LFP2, DFP2, TV2 and NONE.NOTE: Some configurations of
monitor types may fail, this depends onthe Video BIOS and system
configuration.Default: Not configured, and will use the current head's
pipe and monitor. )
But when I use this option in my "Device" Section, I have these lines in
XOrg.log :
(II) intel(0): Output configuration:
(II) intel(0): Pipe A is on
(II) intel(0): Display plane A is now enabled and connected to pipe A
(II) intel(0): Pipe B is on
(II) intel(0): Display plane B is now enabled and connected to pipe B
(II) intel(0): Output VGA is connected to pipe A
(II) intel(0): Output LVDS is connected to pipe B
(II) intel(0): Output TV is connected to pipe none
(WW) intel(0): Option "MonitorLayout" is not used.
And whatever the combination which I puts, that does not change anything
: Option "MonitorLayout" "CRT,TV" or "CRT+TV" (or anything else)
doesn't change anything. And I have always CRT on Pipe A , and LVDS on
Pipe B. Sometimes, when I use others parameters for Monitor
Configuration (TV parameters for example), Pipe A goes automatically on
TV, and if I restore my CRT Monitor parameters for monitor
configuration, Pipe A goes again on CRT. Pipe B never change. I supposed
there is into driver source code a function that determine automatically
which pipe on which output, but I want to fix manually (like
monitorlayout would do it) Pipe A on CRT and Pipe B on TV (Don't need
LVDS).
In order to test the multi screen fonctionnality , I try to remove LVDS
initialisation in intel driver source code. I commented these lines
(i830_driver.c:746) :
if (IS_MOBILE(pI830) && !IS_I830(pI830))
i830_lvds_init(pScrn);
And now, it works better. Intel driver find only 2 outputs (CRT and TV)
, so It automatically puts CRT on Pipe A and TV on Pipe B and I have my
2 images well on each monitors. But I don't like this solution, and I
will prefer to have the good configuration lines to do that.
Maybe anyone knows the solution ?
Thanks :)
