If I understand, patching bios is for the static graphic card option.
This disables the hardware switch completely? If I have windows on
dual boot, will it be able to do dynamic switching?

You can choose in the BIOS setup if you want static or dynamic switching. You don't loose dynamic switching if you patch the bios, but win static one ;)

Many thanks Jef, only the last question for recap.

 From scratch, then I will do:

1) patch Bios.as per ur mail, I'll read this thread:

http://forum.notebookreview.com/sony/473226-insyde-hacking-new-vaio-z-advanced-menu-bios.html

yep, I've done it with no problems at all (serie: vpncz12c5e)


2) disabled the RAID feature from the BIOS (install raid software or
lvm...or nothing :-) )

You can use Raid-0. I've used the ubuntu 10.04 server install CD with dmraid
support and all went pretty well (just had to replace grub2 with grub1 [1])
and then "upgrade" to desktop installing ubuntu-desktop metapackage and some
more stuff.

3) update grub to add the i8042.nopnp option (mouse + keyboard issue)

right. And "i8042.reset i8042.nomux i8042.noloop" look to help to achieve
stability.

4) set acpi_backlight=vendor  (thanks nacho, but if I want to use
invidia?)

backlight control is not supported yet for nvidia, sorry :(



regards!


Many thanks to all staff.

Cheers,
Mauri

Mauri,

No, the procedure is not that hard (but the patch has to be prepared
manually
and checked with an hex editor before applying). What it does is to
enable
the
hidden options in the BIOS settings, in particular the ability to
statically (at
the BIOS level) switch between video cards. The cool thing is that you
can
later
change to dynamic switch using the BIOS settings (what i'll do before
trying to
install Maverick). The only other problem I have is that brightness
adjustment
does not work.


With the intel card try to use kernel parameter acpi_backlight=vendor at
boot time.


regards

Jef

  Hi Jef,
  many thanks for ur support and kindly response.
  Only one think, that I don't undestand.
  If I don't want patch my BIOS,I have some problem with my Ubuntu (I'm
afraid
  to update the bios, it's a hard procedure?)
  I think that I can't switching between video cards, but there may be
other
  problems?
  I'll wait u about the new maverick installation :-)

     Hey Lain,

     Yes, the patch applies to allow static switching between video
cards
(I've
     not been able to get Xorg to work properly using kernel tuning).
The
BIOS
     patch worked very nice, but I would have prefer not to apply it and
use
     pure Linux settings.
     I still have a drive outside the soft RAID volume, so I'll try to
install
     Maverick and let you know whether the dynamic switching works.

     Regards,
     Jef

     Hi Jean,
     many thanks for the reply and all advice.
     I'm sorry but I'm not a expert, then, why I can patched the bios?
only
     for the video card switch?
     In my Sony VPCZ12X5E (2 SSD (64gb x 2) - 1920 resolution) Can I
install
     only ubuntu (10-10 beta) without any patch? I'm afraid to change
the
bios...
     @Martin: I don't undestand what do u mean...
     Cheers,

         I'm reading on internet, that the linux installation, on this
hw, is
         not easy (path kernel etc.)
         Can I install this ubuntu testing version? (Linux kernel
2.6.35)
         Ubuntu 10.10 (Maverick Meerkat) Alpha 3
         I would like install Ubuntu 10.04 LTS, but I'm terrified of
problems
         during installation.
         Another question. I don’t want install 64bit, but a 32bit
with
a
         big-kernel (8gb ram). Is it a problem?
         What do u suggest me?
