I have an ATI Radeon 9500 Pro (R300) video card in a PC that I am trying to setup to play movies and maybe some games on a standard definition NTSC TV.
I am running the radeon driver under a Kubuntu Jaunty alpha release. I upgraded to Jaunty from Intrepid today hoping that a new radeon driver or Xorg might solve my problem, but it didn't help.
The problem I am experiencing is noise in the whites on my screen. It's not related to any specific app. Anywhere there is white, there is noise.
Is there anything I can do to fix this?
I also have this problem. Is there any way (other than reducing brightness in Mplayer) to fix this? Are there any apps which can control brighness values for TV-out?
I do not have this problem with fglrx driver but would rather use radeon driver.
Probably the driver is not correctly clipping the output brightness level to the proper level for NTSC. This would be relatively simple to fix, but it requires someone who knows the driver code and has a bit of time (neither of which, alas, applies to me.)
Are you using overlay or textured video ? Whichever you are using, can you try the other method ?
(or the graphical equivalent) to get around this. Unfortunately, it seems to reset itself each time a new overlay is started. If anyone knows how to make this setting stick it would be helpful, though it still wouldn't fix the noise for things like flash.Code:xvattr -a XV_BRIGHTNESS -v -30
