I am trying to hook up my Ubuntu computer to my Plasma television.
I've recently installed Ubuntu 12.04 on an old Pentium 4 computer that has a standard VESA graphics card, running the default standard VESA graphics driver.
The computer runs fine when attached to a monitor using a VGA to VGA cord.
I've attached a VGA to RCA component cable (red,blue,green) from the computer to my Panasonic TH-42PA60A Plasma television.
The sound card is attached from the computer to the television using an audio-jack to RCA composite (Red, White Yellow) cord.
I receive absolutely no video signal on the television. It appears black. Unplugging the Sound-jack to RCA composite cable did nothing.
When I unplug the computer from the television, and plug it into the monitor using the VGA to VGA cable, without turning off the computer, Ubuntu appears on the monitor with this error ;
I've been informed that I may need to configure the xorg.conf file found at /etc/X11/xorg.conf since "monitors tell computers what they can handle, but that doesn't happen over a composite or component cable".
There was no such xorg.conf file in that directory, so I created one.
I've attempted using the following xorg.conf configuration code which I found on Ubuntu forums
Section "Device" Identifier "Configured Video Device" Driver "vesa" EndSection Section "Monitor" Identifier "Configured Monitor" HorizSync 42.0 - 52.0 VertRefresh 55.0 - 65.0 Modeline "1024x768" 60.80 1024 1056 1128 1272 768 768 770 796 Modeline "800x600" 38.21 800 832 976 1008 600 612 618 631 Modeline "640x480" 24.11 640 672 760 792 480 490 495 50 EndSection Section "Screen" Identifier "Default Screen" Monitor "Configured Monitor" Device "Configured Video Device" DefaultDepth 24 Subsection "Display" Depth 24 Modes "1024x768" "800x600" "640x480" EndSubsection EndSection
After reconnecting the computer to the television and then booting the computer up, I still receive no video signal, only a black screen.
When reconnecting the computer back to the monitor, a CRTC error is showing up on the screen again.
How can configure my xorg.conf file so that I can use Ubuntu on my Plasma television, and is there more, or different things that may need to be done?
