Intel Graphics Get A Boost With Linux 2.6.38, Mesa 7.11

[Dr.Paneas]

I can run World of Padman benchmark ( 82 FPS score) but I cannot run Unigine Heaven or Doom3. Why is that ?

The benchmark starts loading and when it finishes i get a black screen for one second and the Desktop freezes...no keyboard, no mouse..nothing...

I have all the latest drivers and requirements installed

Here take a look

Thanks man

I used to install new kernels via kernelCheck ( http://kcheck.sourceforge.net/ ). Now, I will try your way

[Kano]

Try:

wget -qO- http://kanotix.com/files/fix/mainline/install-38.sh|sudo sh

That will install 2.6.38 final kernel from ubuntu mainline - your kernel is too old.

[Dr.Paneas]

I have installed the latest Intels drivers from PPA:xorg-edgers but I am still unable to play any game or run any graphics test from Phoronix-test-suite.

I can't enable compiz or play any game... I know that as Linux user it would be expected that new hardware doesn't work out of the box, but this is ridiculous ...

Please, when you have time, make an article with directions or guidance for all the rest of us

Just a side comment: what about Virtualbox? Do you have to use Wine with MS Office? Why not install a Windoze OS w/ MS Office in a virtual machine????

Why run extra overhead if there isn't a need for it? Plus VM's are not very desirable in situations where you don't have multicore system or lots of ram to spare.

I'd like to know about the 945 as well- the machine I'm typing from has one. Windows performance is well beyond 2x as it currently stands in some cases. Any kind of boost on the open source side is appreciated... Any news there?

Which applications? For anything using tnl, Mesa's current software implementation is extremely slow (gallium's llvmdraw module is far faster) and is the usual bottleneck. i915g has a tremendous advantage here. If you can post a few comparative numbers between win32, i915c and i915g and open a bug on fd.o, that would be extremely useful. (The key factor for such a performance bug report is the test case and exactly what the expectations are, including the hardware upon which you measure).

So... About that topic

Back on topic: Michael, do you know exactly what code changes allow for this massive improvement?
Also, we've had Sandy Bridge and Clarkdale benches; any chance of some love for the old 945? Still a reasonable user base size from just netbooks, ignoring all the other old boxes lying around.

I'm a giant advocate of odf. Whenever someone can't open it I tell them to open it in MS Office 2010. Whenever they want me to upgrade I can now tell them to upgrade or STFU.

It always works. They send me docx; I always send back odf's. If they send me pdf I send back pdf.

This is no one-way road I and I make that painfully clear.

Isn't Google Docs a little better for MS Office documents ?

Yeah, but is Google Docs available Offline? Sometimes I need it where there's no 3G signal for my notebook...
