- since I plugged an HDMI monitor to my DELL laptop, it no longer wants to display elsewhere, even if no plug connected ( but for the boot sequence ).
( xrandr doesn't see the laptop screen. )
- every 3rd or 4th wakeup, I get no display at all, despite activity is restarting ( fan, disk, ... ).
here are excerpts of syslog that seem to show suspicious things:
