Dual Head with Intel, debugging xorg.conf
Dear X freak,
do you have some idea how to find out what is going on in the grafics driver "intel"?
do you know some __tutorial or examples__? covering xorg.conf and the chip 945GM?
With my new laptop I installed sidux on it. All worked smooth.
Now I'm trying to make a second display work for me, connected to the VGA.
It shows something (1680x1050). Obviously the driver is able to readout the displays data.
(through ddc and EDID I guess). It lacks in a few but annoying details and it seems that I'm not able to define it like I want, e.g. via "modeline" in "monitor" section or upper-left-specification in "ServerLayout".
In Xorg.0.log I found a warning - however everything I do I can't get rid of it:
...
(II) intel: Driver for Intel Integrated Graphics Chipsets: i810,
i810-dc100, i810e, i815, i830M, 845G, 852GM/855GM, 865G, 915G,
E7221 (i915), 915GM, 945G, 945GM, 965G, 965G, 965Q, 946GZ, 965GM
(II) Primary Device is: PCI 00:02:0
(WW) intel: No matching Device section for instance (BusID PCI:0:2:1) found
(**) Chipset override: 945GM
(**) Chipset 945GM found
...
(II) intel(0): Output VGA using monitor section MonitorX60
(II) intel(0): I2C bus "CRTDDC_A" initialized.
(II) intel(0): Output LVDS has no monitor section
(II) intel(0): I2C bus "LVDSDDC_C" initialized.
...
But also, I don't know whether this is of any importance.
(I definetly tried to introduce two monitor and device sections)
snippets of my current xorg.conf:
each monitor has its own "screen" and "device" section. The modeline hase no effect and does not appear in Xorg.0.log.
Section "ServerLayout"
Identifier "2ndview"
Screen 0 "ScrLVDS" 0 0
Screen 1 "ScrVGA206BW" RightOf "ScrLVDS"
