Hi,

forgot to mention that you have to CC: me as I'm not subsribed...

Yes, panel always works from startup. But if I don't have the external display connected at startup then the external display doesn't startup while the panel goes off.

So I guess the panel always works correctly but when the external display goes off, both displays are off and then it's blind typing to get the panel back :-)

See attached files. Only difference I see is in the display size:

+ /home/stefanb/laptop/xrandr/xrandr --verbose --output DVI-D_1 --mode 1280x720 --output PANEL --off
crtc 0: disable
-screen 0: 1280x720 260x146 mm 124.63dpi
+screen 0: 1280x720 262x147 mm 124.05dpi
crtc 1: 1280x720 60.0 +0+0 "DVI-D_1"

+ /home/stefanb/laptop/xrandr/xrandr --verbose --output DVI-D_1 --off --output PANEL --preferred
crtc 1: disable
-screen 0: 1400x1050 283x212 mm 125.26dpi
+screen 0: 1400x1050 285x214 mm 124.41dpi
crtc 0: 1400x1050 60.0 +0+0 "PANEL"

I wonder if there is some overwriting happening on the EDID data?

Regards,

Stefan
