fedora on lenova T520 w nvidia optimus ?

[Genes MailLists]

Interesting looking laptop - and the msata drive thing looks like a
(reasonably priced) way to add SSD for root partition (leaving regular
drive for data).

So does anyone know what works/not works ?

Esp the Nvidia Optimus NVS 4400m - the dual intel + nvidia graphics.

I have not heard much about the VGA switcheroo (assume its needed
here) - maybe its possible to disable the intel graphics in BIOS ? If so
will nouveau work on this ?

Thanks for any insights ..

I don't know if this laptop has a BIOS setting to disable the Intel 
graphics or not. If you cannot disable Optimus via a BIOS setting, then 
the laptop is not usable (currently) with Linux. However, there's a hack 
that may or may not suit your needs.

I haven't tried any of these things since I only have desktops at the 
moment.

This is being discussed fairly actively over on the NVidia forums. Here 
are two links you might be interested in.

I've been following this discussion with some interest since I'm 
considering a laptop.

. . . . just my two cents.

Looks like the BIOS can set it to be discrete only and that should
maybe work - depending if either nouveau or nvidia drivers work after
that ... anyone ?
