I am using Debian Sid on an ATI Radeon IGP 350M based laptop, with a 19' LCD
When the external LCD connected, X can be started and shown on the LVDS(or
the Laptop panel),
'xrandr -q' shows LVDS and VGA-0 are connected and modes properly probed.
However, after the attempt to bring on the external monitor by 'xrandr
--ouput VGA-0 --auto',
the external monitor remains black and has no signal input. Meanwhile the
'xrandr -q' does change with the VGA-0 monitor indicated as been activated
and in preferred mode '1280x1024+0+0'
I googled a lot and tried different approach to hack my way through, however
So I can only ask for help here.
the detail of my problem is raised as a bug in bugzilla:
TIA for any advice
