+++ This bug was initially created as a clone of Bug #15559 +++ Created an attachment (id=15980) xorg log file 2D source is git tip. platform: 915GM On our 915GM machine, the TV did not connect, but xrandr reported TV was connected. output of "xrandr -q": Screen 0: minimum 320 x 200, current 720 x 400, maximum 1024 x 1024 VGA disconnected (normal left inverted right x axis y axis) LVDS connected 720x400+0+0 (normal left inverted right x axis y axis) 0mm x 0mm 1024x768 60.0 + 85.0 75.0 70.1 60.0 832x624 74.6 800x600 85.1 72.2 75.0 60.3 56.2 640x480 85.0 72.8 75.0 59.9 720x400 85.0* 640x400 85.1 640x350 85.1 TV connected (normal left inverted right x axis y axis) 1024x768 30.0 + 800x600 30.0 848x480 30.0 640x480 30.0
attachment #15980 [details] is the bug's xorg log file. Same log with bug #15559.
do we know if this is a regression? can we bisect?
but the log says "Output TV disconnected" correctly. It seems the TV load detect code is random.
"the TV load detect code is random -- it will say 'yes' and 'no' alternately on some machines" - Keithp

We can't reproduce this on 915GM now, so closing it.
is bug# 16566 a dup of this one?
Maybe related(In reply to comment #8) > is bug# 16566 a dup of this one? > Maybe related somewhat, but with totally different symptons. 15663 is no TV connected in fact but randr reports TV connected. 16566 is with TV connected in fact but randr reports TV disconnected.

result of zhenyu's experiment yesterday: it seems that pull the TV cable out and type in 'xrandr -q', it still say TV connected. But run 'xrandr --auto' will refresh the state, then 'xrandr -q' will give correct status. Might because the test machine was once used for TV testing before performed this test.. close this bug anyway.
