[Touch-packages] [Bug 1388647] Re: DRI_PRIME=1 has no effect in Ubuntu 14.10
Dominic Chambers, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ . If it remains an issue, could you please run the following command in the development release from a Terminal as it will automatically gather and attach updated debug information to this report: apport-collect -p xorg 1388647 Please ensure you have xdiagnose installed, and that you click the Yes button for attaching additional debugging information. As well, given the information from the prior release is already available, testing a release prior to the development one would not be helpful. Thank you for your understanding.

[Touch-packages] [Bug 1388647] Re: DRI_PRIME=1 has no effect in Ubuntu 14.10
That's a clever trick, being able to downgrade dependencies like that. Any pointers on how one goes about doing it, since even if I add 'trusty' sources to `/etc/apt/sources.list' then I still only see a single version available to install if I run `apt-show-versions xserver- xorg`? Anyway, great work narrowing it down so quickly! -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1388647 Title: DRI_PRIME=1 has no effect in Ubuntu 14.10 Status in “xorg” package in Ubuntu: Confirmed Bug description: On an Optimus laptop with both GPUs enabled, having run this command so that the Nvidia GPU can be used to offload 3D work from the Intel GPU: ``` xrandr --setprovideroffloadsink nouveau Intel ``` Then running this command: ``` DRI_PRIME=1 glxinfo | grep OpenGL vendor string ``` provides the incorrect output: ``` OpenGL vendor string: Intel Open Source Technology Center ``` when it should actually show that the Nouveau driver is in use for the program. This worked previously in Ubuntu 14.04. Apart from only having a 3.16 kernel (instead of 3.17) Ubuntu 14.10 actually supports recent enough versions of the requisite packages necesarry to get DRI 3 offloading support, so perhaps this is part of the problem. Or, more likely, I notice a Nouveau failure after startup, and then again after running xrandr commands, for example: ``` [ 170.912483] IPv6: ADDRCONF(NETDEV_CHANGE): wlan0: link becomes ready [ 217.550205] thinkpad_acpi: EC reports that Thermal Table has changed [ 223.857442] ACPI Warning: \_SB_.PCI0.PEG_.VID_._DSM: Argument #4 type mismatch - Found [Buffer], ACPI requires [Package] (20140424/nsarguments-95) [ 223.858395] ACPI Warning: \_SB_.PCI0.PEG_.VID_._DSM: Argument #4 type mismatch - Found [Buffer], ACPI requires [Package] (20140424/nsarguments-95) [ 223.860200] nouveau E[PBUS][:01:00.0] MMIO read of 0x FAULT at 0x002140 [ !ENGINE ] [ 224.654622] thinkpad_acpi: EC reports that Thermal Table has changed [ 825.172094] thinkpad_acpi: EC reports that Thermal Table has changed [ 831.132156] ACPI Warning: \_SB_.PCI0.PEG_.VID_._DSM: Argument #4 type mismatch - Found [Buffer], ACPI requires [Package] (20140424/nsarguments-95) [ 831.133030] ACPI Warning: \_SB_.PCI0.PEG_.VID_._DSM: Argument #4 type mismatch - Found [Buffer], ACPI requires [Package] (20140424/nsarguments-95) [ 831.134832] nouveau E[PBUS][:01:00.0] MMIO read of 0x FAULT at 0x002140 [ !ENGINE ] ``` Perhaps this is just a regression in either the Nouveau or Intel drivers for my hardware. I'm using a Lenovo T430. I can confirm that I'm able to start the laptop without errors when I only enable the Intel GPU or NVidia GPU separately, and only see this error when both GPUs are enabled simultaneously.
