If you don't have a model with an integrated GPU then I suspect you may
be looking at the first stages of one of the infamous GPU failures that
plagues the T4x series.

I hope it's not that, as it's a pain to deal with those, but it sure
does sound suspiciously like a number of accounts I've heard...

Subject: [ltp] VGA hotplugging
Reply-To: linux-thinkpad@linux-thinkpad.org

Dear all,

Just wondering - has anyone got VGA hotplugging to really work elegantly =

and seamlessly?

So far, the gnome-xrandr tool (under Lucid) does a wonderful job of =

letting me manually reconfigure the desktop after I plug/unplug a monitor=
=2E

But what I really want is for the following:

  1. Plug in VGA cable
         -> Automatically configures dual-monitors as a larger
            screen (*)
	-> Ideally, adds a 2nd taskbar to the other screen.
            so that each monitor has its own taskbar.

  2. Unplug VGA cable:
	-> reconfigures virtual desktop back to the original
            size. The mouse is now constrained to the actual screen area
         -> All windows are moved back to the visible existing screen
	   and resized.
	=


(*) Depending on the user and the use-case, we may want to:
   -  clone the two displays (what happens if the aspect ratios differ),
   -  extend the desktop for dual-head
   -  clone the two displays, and make the internal resolution/aspect
     match the external one (when giving presentations)


Is there any way to do this already? Has anyone written any scripts to =

do it?

Thanks,

Richard
