Hi all,
Has anyone gotten an external monitor working on a Thinkpad W530 (or
similar, T530, etc) laptop? I've got Fedora 18 x86_64 running integrated
graphics only (I tried getting optimus to work but got tired and banging my
head on the wall).
Any tips/pointers/gotchas will be much appreciated.
Hi
on my W520 I came to the conclusion that the external VGA is not connected
to the Intel chipset at all. It can only by driven by Nvidia hardware.
I worked out a solution (but it is not easy) where I drive the LCD with Intel
and the external VGA with Nvidia.
The secondary X server can be run and stopped indipendently, it is actually
a good setup if you have to use a projector, because you have the LCD with your
usual desktop and the VGA with just what you need to be shown.
I described how I did it some time ago here.
I'll try to find that, it sounds like exactly the sort of setup I am
planning to use on my new system. The only downside I can see is that
once you fire up the apps on the secondary X server you cannot drag the
windows back to the primary.
You could, however, create a conf file for multiple display adapters
with different drivers on the same X server. Last time I used such a
setup was circa RH9/RHEL3 (pre-Fedora, using Matrox Millenium and ATI
Mach64 cards), but I don't see any reason why it wouldn't work (unless
it is one of many things that got lobotomized over time for no good
reason at all - but that's a whole different rant that I'm not going to
go off on right now). Whether such a setup is "pluggable", i.e. will
support adding/removing monitors/adapters/screens dynamically without a
restart, I don't know - I never tried.
