Hi everybody,
Afterdoing some work on my frontend, I've had something interesting come up.
When I try to change the playback brightness, the brightness level on the OSD
jumps from 50% to -1, which is obviously an error condition. Any hints on
how to fix this?
So here is what I changed:
- Upgrade from Debian Sarge to Etch
- Go from XFree86 with 87XX nvidia driver to X.org 7.1 with 9631 Nvidia
driver
- Start using Twinview,
- Enable OpenGl
- Enable XVMC, (though disabling it didn't help)
- Tried to use Chromakey to get color OSD, but that stopped working when I
enabled Twinview.
- Finally got booting over the network working again (BIOS upgrade)
- Used PAM settings to enable realtime priority
I have a Gforce 4MX series card, and I'm using the SVideo out port on it
hooked up to a junky old 20" TV
Any ideas? My gut tells me that its a Twinview problem. I enabled Twinview
because that was the only way I could get OpenGL working (at least with the
old XFree86 setup).
