PSone, epia 5000, Xorg.conf help
I hope I am not out-of-bounds by cross-posting this to the linux forum: (was LCD)
I did the vga mod (succesfully?) to my psone lcd.
I am trying to run it on my epia 5000 motherboard, using linux.
I haven't seen any threads where people have said whether this motherboard supports composite sync.
My attempts to use the modeline from here (for the epia 800):
(xorg reports "no screens found.")
---this results from changing only the HorizSync and VertRefresh lines. (hadn't added the modeline yet; but still fails after this too.)
and I dont know what rest of the xorg.conf file needs.
In console using the boot option vga=0x301, and X (using a generic 640x480x16 xorg.conf file), the psone screen displays two screens side by side (both squished to fit), and at the top of the screen it looks like a stiff wind is blowing(bending) the picture, shifting it. The colors are also off somewhat. I can see xfce good enough to move the mouse to the exit button, but thats about it.
An attempt to run xvidtune on the epia 5000 (using a different monitor) resulted in a message like "video device does not support tuning".
Update: PSone and EPIA 5000, linux xorg partial success
After abandoning this project for many months I came back to it today and after several hours, got lucky.
The screen no longer scrolls like a projector and is mostly stable. [thin black lines (like horizontal rain) appear on the screen but it is almost usable. ]
If the picture attach works, you can see that I am running Xvidtune, but I think I need more modeline adjustment because the problem seems to be out of the range of Xvidtune.
The view is actually significantly more clear than the atttached image.

...I'm still using the trident driver, which apparently from my experience is required if you expect to get Xvidtune to work. (other wise Xvidtunes says something like device does not support ...)
