And (only) this was working for me. The single patches mentioned in the
freedesktop bug about this resume issue did not do the trick for me (and
I assume that is the patch you picked).
Ok, though have you got to the bottom of your flicker issues yet? I'm not
seeing them on my kernel but of course it could be the combination of X driver
etc that is causing it for you - but what I don't want to do is update the
kernel with that commit and find that the flickering problem happens :(.
I guess that the question has to be whether the problem you have happened
before the fix for resume - if so then I'm probably fairly safe updating,
but
if not then I probably shouldn't....

I would guess that means that more changes are required to make
this
work. The problem here is that the kernel which Jesse from Intel has
that
seems to work when resumed is a little different to this one. When I
get
a chance I'll have another look to see if I can work out what is
needed.

I am about to try Ubuntu 10.10 next with this kernel (2.6.36).

The problem is not with the kernel but with the NVidia and
Nouveau
drivers ( or at least that is how it appears. ) The problem
is that in
both modes, both cards appear on the bus, and at boot time
the BIOS
sets up the Intel card REGARDLESS of the mode ( well,
without booting
the old kernel or setting static switching using the BIOS
hack. ) So,
when the NVidia driver tries to load, it assumes that it
already has
its resources mapped but in fact it doesn't - only the
Intel card has
been mapped in. So, you STILL have to boot the old kernel to
use the
NVidia card so that the Intel one is completely disabled and
not
mapped at boot time.
glxinfo | grep ender
This does not work, since I have no working glx module
("extension GLX
missing").
I think that the issue here may be that the NVidia driver
also has
its
own mesa/glx libraries. I think that to get GLX working with
Intel you
will have to re-install the Ubuntu ones, and then again to
get the
NVidia working install the NVidia ones again. In my files
directory is
an rc.local file which in theory could be re-written to copy
the
appropriate files when needed... it should be fairly easy to
do but
unfortunately I don't have the time at the mo... if I
get some time in
the near future I'll give it a go.
That would seem a little odd if you say you get the
desktop - the
desktop
would seem to constitute a "screen" ! For
speed mode you should not
need an xorg.conf file at all - if you have one move
it out of the
way.
There must be something wrong with my system
configuration. I just
started in Speed mode a few times. X loads the i915
driver (lsmod
shows i915 loaded), although I blacklisted that, my
xorg.conf
specifies "nvidia". X also tries to load the
NVIDIA glx module.
Excerpt from my
Xorg.0.log in Speed mode:
As above, in "speed" mode both the Intel and
NVidia cards are active.
The
NVidia driver needs to realise that! Also, in theory we
should probably
patch the i915 driver to not load in speed mode, but this
would be a
very Vaio-Z specific patch unless it could be fitted in with
the vga
switcheroo code.
I can currently only use my Z11 without problems if I
boot the
2.6.31-20 kernel with the NVIDIA proprietary drivers and
an xorg.conf
that specifies to use the nvidia driver.
It should also work if you boot my 2.6.28 kernel which
reboots ( then
select the 2.6.36-0-vaioz one. )
I'm sure that one day this will all "just
work" :(.
Adam
I hope this helpt in making the kernel work for
everybody.
I'd gladly do some more testing.
Philippe
