Default F14 - graphics problem with intel i915

Can anyone help with this.

1) I have Lenovo W520 laptop.

It has Optimus graphics - currently set to Intel Integrated

lscpi reports : VGA compatible controller:
Intel Corporation Device 0126 (rev 09)

I wonder if the '0126' is an issue for fedora ?

2) I have managed to install F14

3) If I boot parted magic 6.1 - it boots up fine - brings up the screen
using intel i915 driver in its 1920 x 1080 (FHD) mode.

Great - that's what I want in fedora.

Its using 2.6.38.2 kernel - /var/log/X.0.log shows intel driver is used.

4) When I boot fedora I have no joy - i compiled the F15 source rpm of
kernel 2.6.38.6 - it does not recognize the intel card and uses VESA
in 1280 x 1024

Xorg log -shows VESA is used.

The screen is messed up - for example the top bar of gnome is "off
screen".

5) I compiled 2.6.39 kernel from F16 source rpm.

It boots fine too - and also brings up VESA driver - screen is no
longer 'messed up' but I am styill stuck on 1280 x 1024.


6) Does anyone know how I can get fedora to use the Intel i915 driver
just like "parted magic" CD does ...

Fedora has to be as good as parted magic .. no?

Help appreciated.


Thanks ..

[PS. I have also tried switching BIOS to nvidia discrete graphics -
none of nouveau, 260 nvidia or 270 (rawhide) nvidia seem to work - they
freeze as soon as the (nomodeset'ed) boot progress bar starts ... i.e.
as soon as X kicks in]

One update - both kernels 2.6.38.6 and 2.6.39 mess up the screen the
same way unless nomodeset is used to boot.

With or without nomodeset, VESA driver is used - with nomodeset
things are visible on screen (but stretched) - without nomodeset things
are 'off screen'.

I'd be happy with nvidia or intel ... but since the parted magic CD
seems to boot fine with intel driver there must be a way in fedora to do
the same ..

Appreciate any help.

More info:

During boot - Plymouth (when nomodeset) seems to be running at the
1920 x 1024 resolution - then just before the GDM login screen - it
jumps to lower resolution ...
