Red Hat Bugzilla – Bug 585490
KMS:Radeon RV100 QY:Radeon 7000/VE Horizontal stripes on TV
Last modified: 2012-08-16 14:23:17 EDT
Description of problem:
When TV output is enabled on Radeon 7000, there are horizontal darker and brighter stripes on the TV screen (see photos).
This does not appear in Windows. Also it's possible to set the resolution on the TV output up to 1024x768 (anything higher causes scrolling - virtual desktop) in Windows but xrandr shows only 800x600.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Boot desktop-i386-20100418.17 with TV connected
TV output with stripes.
Clean TV output.

I'm also experiencing this but on Fedora 13 with a Radeon 9200 (RV280).
I get the same horizontal pattern as in the attached photo when "tv standard" is correctly set to PAL. There is also some distortion in the upper right corner - the picture bends in from the vertical edge.
My TV can also kind of handle NTSC input (an added "feature" with a little distortion) - when I switch tv standard to ntsc the horizontal lines aren't there.
I also don't get the horizontal lines if I boot with nomodeset (though the output is black and white - I get colour (but with expected distortion) if I switch output to ntsc)
This bug appears to have been reported against 'rawhide' during the Fedora 14 development cycle.
Changing version to '14'.
More information and reason for this action is here:
This message is a notice that Fedora 14 is now at end of life. Fedora
has stopped maintaining and issuing updates for Fedora 14. It is
Fedora's policy to close all bug reports from releases that are no
longer maintained. At this time, all open bugs with a Fedora 'version'
of '14' have been closed as WONTFIX.
(Please note: Our normal process is to give advanced warning of this
occurring, but we forgot to do that. A thousand apologies.)
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, feel free to reopen
this bug and simply change the 'version' to a later Fedora version.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we were unable to fix it before Fedora 14 reached end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora, you are encouraged to click on
"Clone This Bug" (top right of this page) and open it against that
version of Fedora.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
The process we are following is described here:
