PostPosted: Wed Mar 17, 2010 7:49 pm    Post subject: [SOLVED] Dual head - xrandr vs. xorg.conf Reply with quote

Hi,

I have slight issue setting up the dual head configuration,
have ATI Radeon 9600pro, left monitor is called DVI-0 and right VGA-0 is detected as primary by default.

Everytime I login into the KDE, DVI-0 is clone of VGA-0 and only way how to change it what works for me is this command:
Code:
xrandr --output DVI-0 --auto --rotate normal --pos 0x0 --primary --output VGA-0  --auto  --rotate  normal --right-of DVI-0


That would represent the desired results, but here is one issue: I have to leave X by pressing CTRL+ALT+F1 and get back with ALT+F7 to see actual dual screen.

Modifying Display Settings in the System settings doesn't work as expected and doesn't remember the configuration so I'd have to set it again after every restart.

Perhaps modifying xorg.conf would do the job better? I'd like to have DVI-0 as primary screen and VGA-0 right-of DVI-0

Here is my xorg.conf:
Code:

I have a static dual head setup with this xorg.conf:

Code:

Section "Device"
        Identifier "video card"
        Option "Monitor-DVI-0" "DVI-Left"
        Option "Monitor-VGA-0" "VGA-Right"
        Option "AccelMethod" "exa"
EndSection

Section "Monitor"
        Identifier "DVI-Left"
EndSection

Section "Monitor"
        Identifier "VGA-Right"
        Option "RightOf" "DVI-Left"
EndSection

Section "Screen"
        Identifier "screeny"
        DefaultDepth 24
        SubSection "Display"
                Depth 24
                Virtual 2560 1024
        EndSubSection
EndSection

OK I am almost there, reduced my xorg.conf to this:

Code:

Section "Device"
        Identifier "9600pro"
        Driver      "radeon"
        Option "Monitor-DVI-0" "DVI-Left"
        Option "Monitor-VGA-0" "VGA-Right"
        Option "AccelMethod" "exa"
EndSection

Section "Monitor"
        Identifier "DVI-Left"
EndSection

Section "Monitor"
        Identifier "VGA-Right"
        Option "RightOf" "DVI-Left"
EndSection

Section "Screen"
        Identifier "screeny"
        Device "9600pro"
        Monitor "DVI-Left"
        DefaultDepth 24
        SubSection "Display"
                Depth 24
                Modes    "1440x900" "1280x1024"
                Virtual 2720 1024
        EndSubSection
EndSection


Issue is that screen VGA-0 is started in 1280x960:
Code:

$ xrandr -q
Screen 0: minimum 320 x 200, current 2720 x 960, maximum 2720 x 1024
VGA-0 connected 1280x960+1440+0 (normal left inverted right x axis y axis) 337mm x 270mm
   1280x1024      60.0 +   75.0     60.0 
   1280x960       60.0*
   1024x768       75.0     70.1     60.0 
   832x624        74.6 
   800x600        72.2     75.0     60.3     56.2 
   640x480        75.0     72.8     66.7     59.9 
   720x405        70.0 
   720x400        70.1 
   640x400        70.0 
   640x360        70.0 
DVI-0 connected 1440x900+0+0 (normal left inverted right x axis y axis) 408mm x 255mm
   1440x900       59.9*+   60.0 
   1280x1024      75.0     60.0 
   1280x960       60.0 
   1152x864       75.0 
   1024x768       75.0     70.1     60.0 
   832x624        74.6 
   800x600        72.2     75.0     60.3     56.2 
   640x480        75.0     72.8     66.7     59.9 
   720x400        70.1 
S-video disconnected (normal left inverted right x axis y axis)


Where could I find out how system did set this resolution - no indication in Xorg.0.log
How to force it to 1280x1024?

It's a bigger alchemy than one would think :)

That's odd, usually X will pick the highest/native resolution for your monitors, which is why I don't specify a resolution in my xorg.conf, just the Virtual (which is the statically allocated maximum size of the framebuffer).

What happens if you select 1280x1024 in lieu of 1280x960 via xrandr?

So now I am confused, does it mean that X log reports active resolution 1280x1024?:
Code:
[    14.949] (II) RADEON(0): h_active: 1280  h_sync: 1328  h_sync_end 1440 h_blank_end 1688 h_border: 0
[    14.949] (II) RADEON(0): v_active: 1024  v_sync: 1025  v_sync_end 1028 v_blanking: 1066 v_border: 0


because it is not, menu on LCD reports resolution 1280x960

There are things I don't understand like: Supported standard timings or Supported established timings as they seem to contradict each other.

Using xrandr will switch to proper resolution, but it's a pain as I have to leave F7 console and come back to see actual change..

To setup my dual screen, I've modified the following file [Xsetup]
Quote:

kroupouk tmp # more /usr/share/config/kdm/Xsetup
#! /bin/sh
# Xsetup - run as root before the login dialog appears
#for ati
#xrandr --output DVI-0 --mode 1920x1200
#xrandr --output LVDS --mode 1680x1050
#xrandr --output LVDS --right-of DVI-0


#For Radeon HD

xrandr --output PANEL --right-of DVI-D_1
xrandr --output PANEL --mode 1680x1050
xrandr --output DVI-D_1 --mode 1920x1200
xrandr --output PANEL --right-of DVI-D_1
#For ATI
#xrandr --output LVDS --right-of DVI-0
#xrandr --output LVDS --mode 1680x1050
#xrandr --output DVI-0 --mode 1920x1200
#xrandr --output LVDS --right-of DVI-0

#xconsole -geometry 480x130-0-0 -notify -verbose -fn fixed -exitOnFail -file /dev/xconsole &

Works like a charm

you're right works like a charm on your computer and mine at work, but not on this one.

It still lies on the fact that xrandr settings won't apply until you rejoin F7 console and that's a real bummer.

I am using RADEON open source driver from kernel, not sure if it hasn't too many modules running with it:
Code:

radeon                609859  2
ttm                    40543  1 radeon
drm_kms_helper         22946  1 radeon
drm                   140024  5 radeon,ttm,drm_kms_helper
fb                     38086  2 radeon,drm_kms_helper
i2c_algo_bit            4056  1 radeon
cfbcopyarea             2785  1 radeon
cfbimgblt               1993  1 radeon
cfbfillrect             2589  1 radeon


I have installed
Code:

x11-base/xorg-server-1.8.1.902  USE="hal kdrive nptl udev xorg -dmx -doc -ipv6 -minimal -static-libs -tslib"
x11-drivers/xf86-video-ati-6.13.1
x11-base/xorg-x11-7.4-r1
x11-apps/xrandr-1.3.2


What else is important to check?

You don't need any screen section. In the Monitor section, set Option PreferredMode to the desired resolution. Also see "man xorg.conf" for a description of that option.

That will pickup wrong resolution for DVI and after login will disable it completely:

Code:

$ xrandr -q
Screen 0: minimum 320 x 200, current 1280 x 960, maximum 1440 x 1440
VGA-0 connected 1280x960+0+0 (normal left inverted right x axis y axis) 337mm x 270mm
   1280x1024      60.0 +   75.0 
   1280x960       60.0*
   1024x768       75.0     70.1     60.0 
   832x624        74.6 
   800x600        72.2     75.0     60.3     56.2 
   640x480        75.0     72.8     66.7     59.9 
   720x405        70.0 
   720x400        70.1 
   640x400        70.0 
   640x360        70.0 
DVI-0 connected (normal left inverted right x axis y axis)
   1440x900       59.9 +   60.0 
   1280x1024      75.0     60.0 
   1280x960       60.0 
   1152x864       75.0 
   1024x768       75.0     70.1     60.0 
   832x624        74.6 
   800x600        72.2     75.0     60.3     56.2 
   640x480        75.0     72.8     66.7     59.9 
   720x400        70.1 
S-video disconnected (normal left inverted right x axis y axis)


I inserted these options and disabled screen section:
Code:
Section "Monitor"
        Identifier "DVI-Left"
        Option "PreferredMode" "1440x900@59.90"
        Modeline "1440x900"  106.47  1440 1520 1672 1904  900 901 904 932  -HSync +Vsync
EndSection
        #Option "Enable" "true"

Section "Monitor"
        Identifier "VGA-Right"
        Option "RightOf" "DVI-Left"
        #Option "Enable" "true"
        Option "PreferredMode" "1280x1024@59.90"
        #Modeline "1280x1024"  108.00  1280 1328 1440 1688  1024 1025 1028 1066 +hsync +vsync
EndSection

Finally resolved that today after having some other system issues.

I found out about KMS, my configuration was more than 2 years old and didn't hear about KMS until yesterday.

At the moment it's working like a charm, dual screen is initiated when running kdm. No further issues, resolved :)
