There's nothing in the changelog about mousedev being built in, but the
current kernel does have CONFIG_INPUT_MOUSEDEV=y.  Have you confirmed that
this was intentional?

It was intentional. I think it was something I discussed with
Kamion/Keybuk awhile back. I made the change and forgot the changelog
entry. Oliver confirmed with me last night about the change. Having
mousedev built-in is all good, since it never gets triggered unless
something like psmouse or usbhid is also loaded.

Intel 915 Graphics drivers

Hi,
Is it possible to add Intel accelerated drivers for GMA 915 chipset?
I don't exactly what it touch (X-server, dri, drm, ...) but it seems 
that its' completely free and so would be the only free hardware 
accelerated platform.
Any idea?

The X bits seem free, but the kernel stuff is seriously non-free. Even
the EULA when you download is non-free. Not to mention that the drivers
are binary only. Not even as useful as nvidia/ati (which allows you to
atleast compile the wrapper for a certain kernel).

Sorry, mostly a no-go.

Enabled 3G in new kernel?

Hi, 

I've noticed this 

http://git.kernel.org/git/?p=linux/kernel/git/bcollins/ubuntu-2.6.git;a=blobdiff;h=54cd8a0d29dfbadc40c447c011cff7199a306add;hp=dd095a0646cf554340a3f87cf5ba594955a61873;hb=ec421b617854bb0ac8b5c7fb9ba9cd92d3d4cc00;f=debian/config/i386/config

enabling the 3/1 split on the newer kernel-image on Ubuntu. The fun
is that it says [UBUNTU:v9fs] Enable on all architectures. I don't see
how's CONFIG_3G related to v9fs.

For one, it breaks lots of virtual machines (Prolog, etc...) we're
using because they need to map more than 1 Gb of memory. Also I think
this change does some other things, like breaking crossover:

https://launchpad.net/distros/ubuntu/+source/linux-source-2.6.15/+bug/31086

but I cannot confirm it, as I don't use crossover. Nor I could add the
info to the bug report without registering.

I would like to know if Dapper will ship with config_3G enabled, 

Thanks,

Emilio

Offtopic note: It's really hard to contribute something to ubuntu bug
tracker when it requires registration and it has no email interface (o
no pointer to that interface), and it's even harder when you are used
to debbugs.

Actually, no, the v9fs config change is at:
http://kernel.org/git/?p=linux/kernel/git/bcollins/ubuntu-2.6.git;a=commit;h=ec421b617854bb0ac8b5c7fb9ba9cd92d3d4cc00
(see the 'diff' link for the various arches towards the bottom of the
page).

The 3G config change is
at:
http://kernel.org/git/?p=linux/kernel/git/bcollins/ubuntu-2.6.git;a=commit;h=9699b892f9728215da351dbf385e6e677bc0ad50 .

After reading the commit logs (and git log on my local tree), I'm not
sure why 3G was enabled. I presume this was unintentional?

Thanks,

Yes, you are right, I just don't understand this git thing enough :)

If it's intended it should be documented in README.Debian or some
prominent place, as it breaks too many setups. 

It's not too much burden to recompile a new kernel if you need more
than 1Gb space, but if it's not documented some people can get crazy
debugging until they realize about the change.

Emilio

The main reason I was looking into this was because of 1GB laptops
needing sleep/suspend support (which doesn't work when someone has >
768MB of memory).

I can disable it, but my assumption was that the current default that I
had setup was no different than the original system. However, checking
the values, it seems I was wrong. I'll revert this back to the default.
I may retest this with 2GB to see if wine still works.

Accelerated graphics questions (many!)

Hi,
Since Xgl is out, hardware accelerated is "the* topic out there!

Would someone explain me exactly what is involved to get 3d acclerated?
As I understand, there is OpenGL, which is a library (Mesa). It gives 
some 3d functions. Without 3d acceleration, the CPU do the hard job.

But if we have a 3d card, then we need something to make that OpenGL 
fast. At this point things get harder to understand...

There is first the DRI/DRM driver. What resides in kernel? DRM? Both?
Is DRI only a shared library that is loaded by OpenGL? Or is it a kernel 
module?

What is the GLX module? A wrapper around OpenGL/Mesa so it is accessible 
through X11?

There are drm.ko and i915.ko modules in /lib/modules/... , what are they 
for? Is that the DRM or the DRI part of Intel 915 platform? Does that 
provide hardware accelerated for Intel GMA 915?

What about integrating r200/r300 drivers in Ubuntu? They seem to provide 
accelerated 3d for ATI cards. Is there a non-free issue?

Thanks to answer all these questions.
Bye.

You desperately need to read this:

AFAIK they are free software. The problem I think is lack of stability, they are
