Testing latest -intel in Ubuntu

[tormod]

There is quite some discussion on intel performance in Ubuntu 8.10, for instance in this bug report: https://bugs.launchpad.net/bugs/252094

I'll open this thread in the hope of bringing the discussion here since it doesn't really all belong in a bug report.

Using Jaunty (Ubuntu 9.04 to-be), if you're into experimental stuff, you can install updated Xorg packages from the xorg-edgers repository https://launchpad.net/~xorg-edgers/+archive

The packages can also be tried out on a live CD (see the link on the repository homepage) for those who do not want to mess up their systems. Unfortunately, no official alpha live CD of Jaunty is released yet, but it is expected before Christmas. The daily-live builds work (http://cdimage.ubuntu.com/daily-live/current/), but as of today they still have the old 2.6.27 kernel. Anyway I recommend everyone that can to already install Jaunty to a separate partition.

The Jaunty 2.6.28 kernel (deb packages) can be found at https://edge.launchpad.net/ubuntu/+source/linux (click on the latest version and eventually you'll find the deb for your architecture). The Jaunty kernel also installs without problems in Intrepid. Some people have successfully installed the Jaunty kernel and the Jaunty xorg-edgers packages in their Intrepid system, but don't count on that to work at any time.

The current version of the -intel driver in the xorg-edgers repository can be confusing. It is 2.4.97 since this was the version inside configure.ac on the git trunk at the time the package was built, and this ends up in the package version automatically (a feature of the auto-xorg-git script which builds these packages pretty much automatically).

On the 2.5.1 branch, the version is 2.5.1 of course. But the trunk should be considered newer, so our 2.4.97 is actually ahead of 2.5.1. You have to convince your package manager (dpkg) about this when it complains about downgrading

Anyway, just yesterday the configure.ac on git trunk was updated to state 2.6.99.1, so later packages will have this version...

Hi im using intrepid (64bit)... and have upgraded to 2.6.28-2-generic and all xedgers jaunty package but no big improvement tested using glxgears
my chipset is GM965/GL960
is there any option to enable in xorg.conf? please help

What is your FPS? Note that for me I only saw improvement after restarting X (before GEM could not be initialized).

You can also try renaming xorg.conf to let X autodetect everything, it might give better results.

You did upgrade to 2.4.97 of course? Without seeing your Xorg.0.log it is difficult to diagnose anything.

BTW, I should mention that I don't have any Intel card myself, so this is untested from my side. But apparently it works for some others, so I suggest you closely follow their instructions.

fps ranging from 550-600.. i have rebooted my system after update..

yup, i'm using bare xorg.conf and

The current drm-modules-source does not build against the new 2.6.28-2-generic kernel in Jaunty, due to some incompatibilities in the nv50 kernel-mode-setting code. If you're only interested in i915 (intel) anyway, you can specify only the i915 modules to be compiled, and save compile time also:

sudo env DRM_MODULES="i915" module-assistant -t auto-install drm-modules

[Biji]

wow.. this is kinda new for me.. i will figure out what you mean..
1. download drm-modules-source
2. install module-assistant
3. and recompile drm module
is that right?

[tormod]

Biji, that posting was not meant for you in particular, I don't whether using stock drm modules or those from git works better for you.

When installing drm-modules-source, it will drag in module-assistant as a dependency. Then you just use the command I gave, which will build and install the modules. If you later want to go back to the official modules, you can just uninstall the package drm-modules-2.6.2* which was built and installed by module-assistant.
