Bug Description

[Impact]

Support for server variants of Intel Ivybridge GPUs were included prior to precise releasing, but the PCI IDs for this specific model that is in the wild weren't added until after. Without these fixes, the desktop will not be accelerated. The uploads only add new PCI IDs, nothing else.

[Test Case]

* Verify your graphics device is 8086:016a in lspci -vvnn
* Install appropriate kernel from https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1087302/comments/1
* Update to libdrm 2.4.32-1ubuntu1.1, and xserver-xorg-video-intel 2:2.17.0-1ubuntu4.3
* Reboot
* Verify i915 loads correctly and intel_drv.so is loaded in /var/log/Xorg.0.log

[Regression Potential]

* The fixes included in libdrm and xserver-xorg-video-intel have no way of regressing anything besides these devices, they only allow the new device to work. The devices are identical to the desktop versions with a different PCI ID so there should be no regression. If a regression were to happen, it would be limited to these devices that previously did not work.

cid:201201-10376

There are three ports, two DisplayPorts and one VGA, only the initial cold plugged port will work, and others will not work if you try to hot swap, but the initial one remains working if you plug back.

And the system became really laggy when plugged DisplayPort, no matter it's coldplugged or hot swap later.

Trying to hotplug on DisplayPort, getting following messages from syslog:

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.7 kernel[0] (Not a kernel in the daily directory) and install both the linux-image and linux-image-extra .deb packages.

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

00:02.0 VGA compatible controller [0300]: Intel Corporation Ivy Bridge Graphics Controller [8086:016a] (rev 08) (prog-if 00 [VGA controller])

So the problem here is that the pci id for this device didn't make it into precise's libdrm/xserver-xorg-video-intel/mesa/kernel. It is the same as a desktop Ivybridge GT2 variant, just missing a trivial pci id addition to make the intel drivers work.

All of them are fixed in raring, all but the kernel are fixed in quantal, I'll prepare SRUs for the userspace packages in precise shortly.

By following Test Case in description, using Kernel from latest v3.7 kernel[0] and @leannogasawara's test kernel[1] , both fixes the DisplayPort and hotplug Issues,

but for xserver-xorg-video-intel_2.17.0-1ubuntu4.3.debdiff , i'm having trouble to build it after patched, please check .log , and therefore it is still no support for Compiz:

Hello Yung, or anyone else affected,

Accepted xserver-xorg-video-intel into precise-proposed. The package will build now and be available at http://launchpad.net/ubuntu/+source/xserver-xorg-video-intel/2:2.17.0-1ubuntu4.3 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, and change the tag from verification-needed to verification-done. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed. In either case, details of your testing will help us make a better decision.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance!

Yes, this seems to be fixed for me now on Kubuntu 12.04 using libdrm from precise-proposed on a Dell Precision T1650 with Xeon E3-1225 V2 CPU P4000 integrated graphics.

Thanks - much appreciated.
