Summary: Problems with xrandr dualhead and docking station
Product: xorg
Version: 7.3
Platform: x86 (IA32)
OS/Version: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: Driver/Radeon
AssignedTo: xorg-driver-ati at lists.x.org
ReportedBy: xweber.alex at googlemail.com
QAContact: xorg-team at lists.x.org
All is done with driver 1:6.7.194-1, but behavior is (almost) the same for
1:6.7.193-1. xorg.conf an (hopefully) all needed logs are attached.
The laptop (DELL latitude d810) is started inside its docking station (with the
lid closed). At docking station two Dell UltraSharp 2000FP (20,1" Active Matrix
TFT LCD) are connected. One via DVI-port, the other on the VGA-port.
1. distortion with lid closed
=============================
The (for kdm) login screen is disorted - the monitor shows 1600x1200 and the
displayed elements are arranged for (laptops LVDS size) 1680x1050. The lid
state is reported correctly
cat /proc/acpi/button/lid/LID/state
state: closed
but the driver seems not to take care of that.

The screen looks like an overlayed (repeating) desktop
A "xrandr --output LVDS --off" corrects the disortion for the current session.
2. getting both monitors to work (as it was with mergedFB)
==========================================================
I have tried various combinations how to get them (both) to work at the same
time. With DDC activated I get following result:
xrandr
Screen 0: minimum 320 x 200, current 1600 x 1200, maximum 3200 x 1200
VGA-0 connected (normal left inverted right x axis y axis)

800x600 60.3

S-video disconnected (normal left inverted right x axis y axis)
Which seems to be quite normal. But I cannot start the VGA-connected monitor:
xrandr --output VGA-0 --left-of DVI-0 --mode 1600x1200
...
(WW) EDID preferred timing clock 162.00MHz exceeds claimed max 160MHz, fixing
(II) RADEON(0): DDC Type: 3, Detected Monitor Type: 1
(II) RADEON(0): EDID data from the display on connector: VGA
----------------------
...
(WW) RADEON(0): DDC2/I2C is not properly initialized
(II) RADEON(0): DDC Type: 0, Detected Monitor Type: 0
(II) RADEON(0): Detected Monitor Type: 2
in RADEONProbeOutputModes
(II) RADEON(0): No valid mode specified, force to native mode
(II) RADEON(0): Total number of valid FP mode(s) found: 1
the VGA-0 stays black with some flickering.
Maybe the EDID information is causing that - so i added
Option "IgnoreEDID" "On"
to xorg.conf.
(II) RADEON(0): DDC Type: 0, Detected Monitor Type: 0
(II) RADEON(0): Detected Monitor Type: 2
in RADEONProbeOutputModes
(II) RADEON(0): Added native panel mode: 1680x1050
init memmap
init common
init crtc1
init pll1
restore memmap
(II) RADEON(0): RADEONRestoreMemMapRegisters() :
(II) RADEON(0): MC_FB_LOCATION : 0xd7ffd000
(II) RADEON(0): MC_AGP_LOCATION : 0xffffffc0
restore common
restore crtc1
restore pll1
finished PLL1
restore dac
and VGA-0 looks like old crt's with wrong Hz values (some horizontal stripes,
but mainly black)
So step #3 is NoDDC to let me have control which modeline is used for monitor
setting. Now DVI-0 stays black, but VGA-0 becomes to life (with same disortion
problem in #1).
switching to vt-1 and back to X now I can get both monitors to work (VGA-0 @
1600x1200 and DVI-0 @ 1680x1050).

Whooh - strange. DVI-0 is disconnected but shows what is on LVDS.
ok, lets switch off LVDS
xrandr --output LVDS --off
and DVI-0 is entering darkness.

now i want to have DVI-0 @ 1600x1200
xrandr --output DVI-0 --right-of VGA-0 --mode 1600x1200
xrandr: cannot find mode 1600x1200
ok, no ddc so it does not have the mode (but the modeline is configured in
xorg.conf)
xrandr --addmode DVI-0 1600x1200
and it shows
DVI-0 disconnected (normal left inverted right x axis y axis)
1600x1200 60.0
ok, now lets activate it:
xrandr --output DVI-0 --right-of VGA-0 --mode 1600x1200
and
xrandr
Screen 0: minimum 320 x 200, current 3200 x 1200, maximum 3200 x 1200

but however: both monitors are doing what it is expected.
With driver 1:6.7.193-1 the DVI-0 will remain at black.
xrandr is reporting I would see the desktop on LVDS, but it is on DVI-0. It's
quite hard to have a script with this misleading reporting what devices are
used.
Also: is there a way to have DDC activated and xrandr to use the provided
modeline in xorg.conf, so i could benefit from "monitor is plugged"?
3. thanks!
==========
6.7.x series gives me about +900 fps with glxgears. Thats almost what flgrx
gave me (just 150 fps missing). Great work!! Thank you very much!
