[mythtv-users] xrandr opensource radeon using xorg.conf

[Dan Smith]

First off I'm not real sure if this is a bug or a configuration error
on my part, also I'm not sure if its X, gnome, or mythtv thats causing
me grief.

I'm trying to get a dual screen setup working for my mythfrontend. I'm
using a compaq laptop with radeon graphics
mrplow at compaq-desktop:~$ lspci|grep VGA
01:05.0 VGA compatible controller: ATI Technologies Inc Radeon XPRESS
200M 5955 (PCIE)

I'm using the open source radeon driver in Ubuntu 9.10. At first I had
my xorg.conf setup with bare minimum  content as such:

Section "Screen"
        Identifier "Screen0"
        Device     "Card0"
        SubSection "Display"
                Depth     24
                Virtual 2080 800
        EndSubSection
EndSection

Section "Device"
        Identifier  "Card0"
        Driver      "radeon"
        VendorName  "ATI Technologies Inc"
        BoardName   "Radeon XPRESS 200M 5955 (PCIE)"
        BusID       "PCI:1:5:0"
EndSection

then running this script following gdm login
mrplow at compaq-desktop:~$ cat xrandr.sh
#!/bin/sh

xrandr --output S-video --addmode S-video 800x600
xrandr --output S-video --mode 800x600 --pos 0x0 --primary --output
LVDS  --mode 1280x800 --pos 800x0 --right-of S-video

however s-video wasn't always switching over, sometimes the tv monitor
would remain blue but it would flicker like the v-hold was off on the
tv.
When it did work, it worked well, mythtv would start on the tv monitor
every time and video played fine.

My goal was to integrate the tv into xorg.conf so it would switch over
earlier and be more reliable.
After reading and many failed attempts I came up with this xorg.conf
which works great
mrplow at compaq-desktop:~$ cat /etc/X11/xorg.conf
Section "Monitor"
        Identifier  "TV-monitor"
        Option      "Left Of" "LVDS-monitor"
        Option      "DPMS"
        Option      "Position" "0 0"
EndSection

Section "Monitor"
        Identifier  "LVDS-monitor"
        Option      "DPMS"
        Option      "Position" "800 0"
EndSection

Section "Screen"
        Identifier "Screen0"
        Device     "Card0"
        SubSection "Display"
                Depth     24
                Virtual 2080 800
        EndSubSection
EndSection

Section "Device"
        Option      "ForceTVOut" "true"
        Option      "TVStandard" "ntsc"
        Option      "monitor-LVDS" "LVDS-monitor"
        Option      "monitor-S-video" "TV-monitor"
        Identifier  "Card0"
        Driver      "radeon"
        VendorName  "ATI Technologies Inc"
        BoardName   "Radeon XPRESS 200M 5955 (PCIE)"
        BusID       "PCI:1:5:0"
EndSection

The only problem is that mythfrontend starts on the laptop screen no
matter what I try.

I tried devilspie to force mythtv to start at 0,0 but doesn't seem to help.
I don't want to use compiz to move the window because it seems silly
to enable compiz just to get a program to start in the right position.

If I change the virtual screen size to 2079x800 (1 pixel smaller than
it should be) programs start in 0,0.
Although the laptop screen is half borked, not ideal as I would like
to have a conky instance on the laptop screen with upcoming recordings
info and I need the full 1280x800 res.
Right now I'm running it with a virtual screen of 1600x600 which
lowers the laptop res to 800x600 but at least programs start in the
right position.

running my xrandr.sh script along with the proper xorg.conf with the
added monitor sections still doesn't solve programs starting in the
correct position.
