Description of problem: DRM is not enabled for G41 chipsets Version-Release number of selected component (if applicable): kernel-PAE-2.6.27.19-170.2.35.fc10.i686 kernel-PAE-2.6.27.21-170.2.56.fc10.i686 How reproducible: Always Steps to Reproduce: 1. Boot computer 2. Start X Actual results: No 3D Graphics (and X freezes, but that's some other error) Expected results: 3D Graphics (and X working) Additional info: When I compile 2.6.27.19-170.2.35 with the following patch added at the end, X works with 3D and compiz enabled. I don't know why this patch hasn't made it into the mainline kernel. I found the patch at: http://www.mail-archive.com/dri-devel@lists.sourceforge.net/msg36886.html and made a small modification to fit the Fedora kernel
Created attachment 337490 [details] Patch that enables DRM for Intel G41 in 2.6.27 kernel
Huh, I can't find this patch anywhere upstream, not even in drm-next in the Fedora rawhide tree...
Is there anything you'd like me to do to help this along?
Not supported upstream yet, bug here: https://bugzilla.redhat.com/show_bug.cgi?id=493307 The chipset has known problems.

We're running 40 F10 computers in a lab with the G965, G31, G35 and G41 chipsets. If there's anything we can do to help troubleshoot or resolve this, please let me know.

Here's the right upstream URL: http://bugs.freedesktop.org/show_bug.cgi?id=21095 We don't have a G41 here and the intel guys says that the one system they've tried had a memory problem (too much stolen memory afaik). That may be a problem with the specific system they had or the chipset in general. I suggest posting details of you setup and experiments with enabling the G41 in the upstream bug. thanks, Kristian
It looks like a patch has been added to 2.6.30-rc4 mainline (according to the freedesktop bugzilla and it seems that someone recently built kernel-2.6.30-0.76.rc4.fc12 which is clearly for f12, but might be worth trying (read I'm trying it tomorrow some time) http://koji.fedoraproject.org/koji/packageinfo?packageID=8 http://koji.fedoraproject.org/koji/buildinfo?buildID=100421 Thought the heads up was worth it.
I can confirm that with kernel 2.6.30-rc4.fc12.586 hardware acceleration is working properly on this chip set. Compiz, textured video and dri2 are all working perfectly. Can we have this patch pushed into a fedora 11 kernel?
I've tried the above kernel, but it doesn't finish booting (with I think some PCI kernel issues) Is there any chance of rolling this into a koji f11 kernel build to test?
*** Bug 487619 has been marked as a duplicate of this bug. ***
I'm having troubles using any of the kernels with this patch. I've filed a separate bug as it may not be Intel G41 DRM related. I'm mentioning it here as I suspect it is. https://bugzilla.redhat.com/show_bug.cgi?id=499779
Have anybody else tried the kernels with G41 support? Either try an F-12 kernel or get this F-11 build: http://koji.fedoraproject.org/koji/buildinfo?buildID=101268 thanks
I tired it with the F-11 build and it works fine after boot up. The fancy boot screens do not work properly, but everything else is just fine. The 2.6.30* kernels also work at least for me. Lspci is showing: 00:00.0 Host bridge: Intel Corporation 4 Series Chipset DRAM Controller (rev 03) 00:02.0 VGA compatible controller: Intel Corporation 4 Series Chipset Integrated Graphics Controller (rev 03)
I've upgraded one of my G41's to Rawhide, installed the kernel, and it works great (better than the G31 that's running an identical install, actually) except for one minor issue: Warzone doesn't work. The startup screen is fine, but once you start playing, none of the 3D stuff is rendered. Tuxcart (fullscreen), Glest (fullscreen) and Neverputt (windowed) all work completely correctly.
Support added in 2.6.27.24-170.2.61 and later F10 kernels.
