Re: xawtv: black Lines, again

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]



I too have the Tyan Tiger 133. I had a bizarre file corruption error when using a HPT370 IDE card at high throughput. (2 bytes every 350MB or so) Aparrently, there seems to be a bug in the VIA chipset, although I think it has been fixed in the newer kernels. Adjusting the PCI latency was supposed to be a poor work-around. I have just installed the 2.4.7 kernel, but I haven't had the chance to test it.

I know there was some discussion last month re: black lines appearing
on the right side of xawtv overlay images when scaled beyond a certain
point, I've recently changed motherboards and now I'm affected as
well.  Any ideas on how to fix this?

Before (everything worked fine):

MB:      Asus P3C-D (Intel 820 chipset)
Card:    GeForce2 GTS
Driver:     nv or nvidia (closed source), both worked fine; with nvidia
         driver xawtv would change resolutions to get to fullscreen.
XFree86: 4.0.1 or 4.1, both worked fine

now:
MB: Tyan Tiger 133 (Apollo 133A chipset)

Since the only thing that changed from a perfectly working
configuration to the black-line haunt was the MB/Chipset, I've spent
most of my time trying to tweak X, driver versions, and AGP settings
with no luck - the lines remain.  No xawtv options (outside of using
grabdisplay) seem to have any effect either. Any other ideas to try?

You need to play with the PCI latency options for your M/B. The black stripes happen when you run out of PCI bandwidth for transfering the images to the screen.
