 |
|
hello,
i followed the instructions of http://gentoo-wiki.com/HOWTO_Separate_x-screens_on_Monitor_and_TV but i won't see any picture on my tv : /
http://files.h3nk.de/xorg.conf
this is my xorg.conf
when i run | Code: | | $ DISPLAY=:0.1 gmplayer |
i get this error
| Code: | | vo: couldn't open the X11 display (:0.1)! |
can anybody tell me what i did wrong or if there is something i missed while configuring my X?
i tried several howto and this seems to be the best to serve my needs.
nvtv won't work for me, because my Geforce FX obviously is not supported
Thank you |

According to the nVidia readme, it looks like you need to specify the same BusID in the device section for both cards:
| Quote: | Appendix P. Configuring Multiple X Screens on One Card
__________________________________________________________________________
Graphics chips that support TwinView (Appendix G) can also be configured to
treat each connected display device as a separate X screen.
While there are several disadvantages to this approach as compared to TwinView
(eg: windows cannot be dragged between X screens, hardware accelerated OpenGL
cannot span the two X screens), it does offer several advantages over
TwinView:
If each display device is a separate X screen, then properties that
may vary between X screens may vary between displays (eg: depth, root
window size, etc).
Hardware that can only be used on one display at a time (eg: video
overlays, hardware accelerated RGB overlays), and which consequently
cannot be used at all when in TwinView, can be exposed on the first X
screen when each display is a separate X screen.
The 1-to-1 association of display devices to X screens is more
historically in line with X.
To configure two separate X screens to share one graphics chip, here is what
you will need to do:
First, create two separate Device sections, each listing the BusID of the
graphics card to be shared, each listing the driver as "nvidia", and assign
each a separate screen:
Section "Device"
Identifier "nvidia0"
Driver "nvidia"
# Edit the BusID with the location of your graphics card
BusID "PCI:2:0:0"
Screen 0
EndSection
Section "Device"
Identifier "nvidia1"
Driver "nvidia"
# Edit the BusID with the location of your graphics card
BusId "PCI:2:0:0"
Screen 1
EndSection
Then, create two Screen sections, each using one of the Device sections:
Section "Screen"
Identifier "Screen0"
Device "nvidia0"
Monitor "Monitor0"
DefaultDepth 24
Subsection "Display"
Depth 24
Modes "1600x1200" "1024x768" "800x600" "640x480"
EndSubsection
EndSection
Section "Screen"
Identifier "Screen1"
Device "nvidia1"
Monitor "Monitor1"
DefaultDepth 24
Subsection "Display"
Depth 24
Modes "1600x1200" "1024x768" "800x600" "640x480"
EndSubsection
EndSection
(note: you'll also need to create a second Monitor section) Finally, update
the ServerLayout section to use and position both Screen sections:
Section "ServerLayout"
...
Screen 0 "Screen0"
Screen 1 "Screen1" leftOf "Screen0"
...
EndSection
For further details, please refer to the XF86Config(5x) or xorg.conf(5x)
manpages. |

If you're using twinview, your resolutions will have to be the same for both the TV out and for the monitor. You probably want to have two separate displays.
When you boot up, and your BIOS is POSTing, does your TV display anything?
Also, in order for the tv out to be enabled, something needs to be plugged into it when you boot the system. Otherwise, nothing will ever be displayed no matter what you do. |

He does have two separate displays configured, but if you're planning on using twinview, you'll want to uncomment it from your xorg.conf  |

thank you so far but still i don't get anything on my tv. i added the busid-entry to my second device, and then my X wasn't able to start anymore. i got an error from it like "(EE) the specified hardware is not supported"
i'll continue searching for the reason of my misfortune |

Hi
I don't know if i can help, but i was doing the exact same setup, where I'm running 2 seperate screens off of one nvidia mx440se, it drove me nuts for about 5 builds of the kernel before i started reading about the seperate X screens on the gentoo wiki, i finally disabled all frame buffer support in the kernel and re-installed the nvidia-drivers, now i have tv out while surfing the web.
also I am now trying to figure out how to get gPodder to use vlc on the 2nd screen?

i don't want to miss my framebuffer i think, though i don't see why the framebuffer should influence the way X works...
doesn't anybody have a working x configuration with tv-out which i could just test?
