[gentoo-user] Intel Video and i915 driver

[gentoo-user] Intel Video and i915 driver

[Willie Wong]

Hi list:

I found the following problem when trying to set-up X on my Gigabyte
Netbook, model T1028M. Firstly, about the hardware

lspci shows
 00:02.0 VGA compatible controller: Intel Corporation Mobile 945GME
 Express Integrated Graphics Controller (rev 03)

So I tried the i915 kernel driver with Kernel Modesetting. I booted
with kernel option

 i915.modeset=1 video=1024x600

the resolution is the native resolution on the netbook. I tried to
start X using the configuration generated by X -configure, and it
errors out with 

 drmOpenByBusid: Searching for BusID pci:0000:00:02.0
 drmOpenDevice: node name is /dev/dri/card0

Digging in a bit more into the boot log gives the following snip from

I'm not quite sure I understand what's going on here. Any thoughts?
I'm not even sure what information may be useful, so please let me
know what I need to give. 

Thanks,

Searching for 'intel' in the kernel menuconfig turns up 945GM, but only
in framebuffer drivers marked 'experimental'.  I'm thinking the intel
driver for X doesn't support that chip yet, but I'm guessing.

You could try the vesa driver instead, just to get it working.

the 2009 Q3 release should support my card.

It is not that new a chip-set: having been around a couple years
already I think.

It is said that papers in string theory are published at a rate
greater than the speed of light. This, however, is not problematic
since no information is being transmitted.

Seems to be some sort of regression? I downgraded to
gentoo-sources-2.6.31-r9 and have no problems. But both 2.6.32 and
2.6.32-r1 give me the broken behaviour. 

I'll mark this thread as [SOLVED] because a workaround has been found. 

Cheers,

You should approach relationships like chess. And preferably as Deep Blue plays
it, or at least as Kasparov.
