Arch Linux / XFCE / X / SDTV Configuration


I'm trying to configure an old desktop to use a standard-definition television as a monitor and am having some issues getting X to work properly. Relevant hardware details:
  • 2.93 GHz Celeron D (133x22)
  • ASUS 845G Chipset Motherboard
  • 1 GB DDR 333 RAM (2x 512 MB)
  • PNY Verto GeForce FX 5200 PCI (NV34) 256 MB
  • 20" Toshiba 20AF41 CRT TV Over S-Video

The ultimate goal of the project is to boot the PC into an emulator front-end to run old console video games, so high-resolution display isn't an issue. As the title says, I'm running XFCE from inside Arch.

During initial installation I had an old computer monitor hooked up to the PC via VGA and everything displayed nicely. However, when I switched over to the TV exclusively over S-Video the system won't make it to the login screen. Initial POST and start-up are legible, but once X tries to load the screen becomes scrambled and doesn't progress.

From the log output I clearly see that it can't properly set the refresh rate of the TV, but I've tried a number of configuration settings both manual and automatic without success.

Anybody have any ideas?

It also says it is unable to find initial modes and that the output is enabled but it has no modes (863.897).

I think you need to re-write your xorg.conf -- try just setting one mode with the correct refresh rate (whatever that is).

I don't use NVIDIA though, so I may be completely wrong here.

Some links:
https://wiki.archlinux.org/index.php/Nouveau#Dual_Head
https://wiki.archlinux.org/index.php/Xrandr

Does your system load the X server correctly if you connect it to a normal monitor without the xorg.conf?

Just to close the loop on this, I tried a number of different approaches to get that TV to play nicely with X over S-video and ultimately gave up. In the end I dropped $10 on a USB-powered VGA-to-RCA converter box and put this issue behind me. I hate throwing money at problems, but in this case I decided my time was worth more.

To Head_on_a_Stick's comment, yes, with no xorg.conf file and a spare LCD monitor hooked up over VGA everything worked just fine; that's how I initially installed Arch. I ended up using an xorg.conf file to adjust overscan settings after buying the converter box, but that was about it.
