Description Ondrej Zary 2010-04-23 20:26:55 UTC
Description of problem:
This card has VGA, DVI and S-video outputs. The TV is detected as connected even when it's not. This causes VGA output not to work. When two monitors are connected (the 2nd one through DVI-VGA adapater), X startup takes ages (with monitor blinking many times), then finally desktop appears on DVI. xrandr shows that TV-1 is connected even when it's not:

Using "nouveau.tv_disable=1" kernel parameter makes VGA output work and also fixes slow X startup.

Comment 3 Ondrej Zary 2010-04-23 21:06:32 UTC
When I boot with only DVI attached and nouveau.tv_disable=1 and hot-plug VGA monitor, it does not work. xrandr shows that it's attached, modes are detected properly and even signal is present (goes out of standby) but the screen is blank. However, when I attach TV to the S-video port, I see a unsynchronized image there.

Comment 4 Bug Zapper 2010-07-30 11:27:45 UTC
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:

Comment 5 Ben Skeggs 2010-09-30 05:25:22 UTC
Does this still occur with the latest F14 kernel?

Comment 6 Ondrej Zary 2010-10-05 19:53:00 UTC
With desktop-i386-20101003.16.iso, VGA output works when used alone.

When both DVI and VGA outputs are connected at boot, VGA outputs incorrect signal (monitor OSD displays "input out of range") and xrandr shows that TV is connected even when it's not.

When booted with VGA-only and hot-plugging DVI, both monitors work fine. When the VGA is hot-unplugged, bogus TV is detected again and VGA output stops working until reboot.

Comment 7 Adam Williamson 2010-10-07 19:38:37 UTC
Ben: note the nightlies still have kernel -28 as that was the last one submitted as an update, if any of the changes since -28 affect this, let us know.

Comment 8 Fedora End Of Life 2012-08-16 17:37:59 UTC
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Fedora's policy to close all bug reports from releases that are no 
longer maintained.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:
