Hi!

I'm using rc5 and I can do suspend with no problems. Even the screen
going blank after resume and the brightness adjustment which were
not working in previous releases now work. My only problem while
using intel is no sound.

I did apply the infamous patch to the BIOS so I can do static
switching and only one card is active at any time. I suppose that
may be one reason I can suspend/resume ok and you cannot...


Yes, I think that's probably right.  I'm running the 2.6.37-rc kernels
with a normal BIOS and have been unable to suspend for a while now.
I've reported this to the pm-utils maintainer:

Hello,
I use the factory BIOS and suspend to ram is working fine with the 2.6.37-0.rc5.git2.1.bz638912.fc15.x86_64 kernel. 

I'm only using the intel graphics, never tried nvidia under Linux
However, there is no sound at all. I just updated to the kernel 2.6.38-0.rc6.git0.1.fc16.x86_64, but audio is not working either :-((

Hello David,

thanks a lot for your fast answer !

I took the kernel-2.7.37-0.rc3.git2.1.fc15.x86_14 and it does work
! I now can use the full resolution of 1920x1080. However, I had
to remove "nomodeset" in the kernel params.

Do you rather recommend one of the other 2.7.37 kernels ? In fact,
in the current version, suspend to RAM and disk does not work, nor
the audio.
Looking at the threads, it seems to be "normal" that audio does
not work, but other people seem to have suspend working.
This would be very useful for me since I usually never boot me laptop ;-)

Also, both graphic cards are on (using lspci) and I get 23.8W
power consumption ! Is there a way to "switch off" the Nvidia card
?

Hi,

I am also a Fedora fan and I'm using two kernels:

*Nvidia* - (noveau driver) - most recent Fedora kernel from updates
*Intel* - most recent fedora 15 kernel release candidate,
available here: http://kyle.fedorapeople.org/kernel/

Check my message from 11/18/2010 on the archives with some hints
for configuration/install and solving resume/suspend problem.

I just updated to the rc5 kernel but I still have the problem of
not having sound available...

I tried running

alsamixer -c0

And I get the following output:


?????????????????????????????? AlsaMixer v1.0.23

?                This sound device does not have any controls.


Which is strange, the card seems to be detected but cannot be
used. In Gnome Sound properties no hardware is present.

Any hints?

Kind regards,
David

Hello,

I am using Linux on a Vaio VGN-SZXWN since more than three years and I
really like this machine. Everything works fine (using Fedora Core 12).

I just got a new Vaio, a VPC-Z13 which has i7 M640 CPU, 1920x1080
display and SSD disks. Unfortunately, I've quite some trouble installing
Linux on it. I'm used to Fedora and KDE, and I tried FC14. This comes
with an 2.6.35.6-45 kernel and grub 0.97.

It only installs when I use the vesa X11 driver (version 2.3.0-1) and I
end up with an ugly 1280x1024 resolution. The Fedora release notes quote
that this is related to missing eDP support in this kernel. There are
quite some messages on various lists about this issue, but I've trouble
to filter out a clear solution (if there is one :-(
There seems to be a specific solution for Ubuntu
(http://www.voip-x.co.uk/files/adam/IMPORTANT_README), but if possible
I'd like to keep Fedora, simply because I'm used to it ;-)

Can you please recommend a version of the kernel, grub, X11 that will
work with a 1920x1080 resolution (I don't care about the Nvidia
Graphics) ?

By the way, an update of all the packages resulted in a X11 freeze after
reboot. Right now, I don't know whether this happens because of newer
drivers or a different X11 configuration (not vesa anymore). I would
need to go again though a complete reinstall, but I could of course do
this if it is useful ;-)

Upgrading the kernel alone seems to be OK (2.6.35.10-74), removing
"nomodeset" from the kernel params results in a freeze ...

Thanks a lot for your help !

Holger
