Hi Everyone,

I have an external monitor connected to my laptop via HDMI which I use side by side to get an extended desktop.

When I boot the system with 3.5 Kernel I don't get any signal on the external monitor, laptop display and everything else work fine.

It works fine with 3.4.x Kernels, and I believe it's not a X problem as it's not getting any signal even before X starts (It does with 3.4.x).

I was wondering if anyone else has this issue and possibly a solution, or is this something I need to submit upstream?

Thanks.

What's the output of xrandr? Try something like xrandr --output LVDS1 --auto --output VGA1 --auto --right-of LVDS1

xrandr output http://pastebin.com/z9G4n1Sp This is what I use to initialize the two monitors when X starts xrandr --output LVDS1 --auto --primary --output HDMI1 --auto --right-of LVDS1 And it has no effect as the monitor connected to receives no signal (it goes to sleep) Also, as I mentioned before I don't see the output during the boot either so I assume this is not an X thing. Maybe 3.5 has some modules turned off by default? or this is a bug. I couldn't diagnose it properly. Thanks. -- Sudaraka.
