Description Richard Goedeken 2007-12-19 14:57:49 UTC
- System: AOpen MiniPC MP965-DR
 - CPU/RAM: Core 2 duo T7500, 2GB ram
 - OS: Fedora 8
 - X server: xorg
 - intel_drv.so: built from git checkout 12/09
 - mesa/drm drivers: built from git checkout 12/09
 - system outputs: VGA, TMDS-1, LVDS, TV
 - TV: 32" Sony WEGA, NTSC 480i only

This bug documents an individual problem - several problems were reported at once in #13611, and I am now separating them as requested.

With only the TV connected, the display appears correctly at BIOS start time and I am able to boot into X and get a good display.  However, with both the TV and the VGA connected, I am never able to bring up the TV display.

I have used xrandr --set TV_FORMAT and --mode commands to try different
resolutions and output signal formats.  However the TV display is always blank.  I will attach the xorg.conf, Xorg.0.log, and the output from xrandr --verbose.

The xorg.conf seems fine (though you can also try a normal xorg.conf without any specific TV setting then use xrandr to setup VGA+TV), and the Xorg.0.log says TV connected to Pipe B.

Since I haven't tested this bug since originally reporting it last december, tonight I tested it again.  Unfortunately it's only gotten worse.

I'm currently running with Xserver 1.4-branch (tip as of July 8th, tagged 1.4.2) and xf86-video-intel-2.4 branch, commit 7e51384c973a96366b02ea646392c43574674111 (right before the commit which causes bug #16638).  DRM is from the git tip as of July 8th.

I connected both the component TV output and the VGA output and cold-started the MiniPC.  The BIOS and initial Fedora 8 boot log appeared only on the VGA monitor - the TV was blank.  At the point where the Redhat Graphical Boot screen would normally appear (which starts the intel xf86 driver), the machine hard locked.  The VGA monitor went blank (power saving mode), the TV remained blank, the disc access light stopped flashing.  Pressing control-alt-delete did nothing - I had to power cycle to bring the machine back up.

Please test against current xf86-video-intel git master.
