PRIME multi-GPU support was added to xserver-xorg-video-nouveau 1.0.2. See http://www.phoronix.com/scan.php?page=news_item&px=MTE4MzA
When using this driver in conjunction with xserver 1.13 it should no longer be necessary to use Bumblebee. If you need the NVIDIA GPU to scan-out what is being rendered (drawn) by the Intel chip (such as if the machine's only display connector is wired to the NVIDIA GPU), you will also need the reverse PRIME support described at http://www.phoronix.com/scan.php?page=news_item&px=MTI5NDU See https://launchpad.net/ubuntu/+source/xserver-xorg-video-nouveau for the driver version available in each Ubuntu release. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-nouveau in Ubuntu. https://bugs.launchpad.net/bugs/700646 Title: nVIDIA 425M (with Optimus) is not detected Status in “xserver-xorg-video-nouveau” package in Ubuntu: Confirmed Bug description: I've recentely purchased a new (custom build) laptop with a nVIDIA GT425M graphics card and i5-460M processor. This card supports Optimus, which Ubuntu (and Linux) does not support (I can live with that). But I can't get this GT425M to work, the only gpu being used is the integrated GPU in the i5 processor. It seems that Ubuntu does not detect the nVIDIA card at all: $ dmesg|grep -i nouveau [ 3.468455] nouveau 0000:01:00.0: power state changed by ACPI to D0 [ 4.625468] nouveau 0000:01:00.0: power state changed by ACPI to D0 [ 4.625480] nouveau 0000:01:00.0: enabling device (0104 -> 0107) [ 4.625487] nouveau 0000:01:00.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16 [ 4.625491] nouveau 0000:01:00.0: setting latency timer to 64 [ 4.629190] [drm] nouveau 0000:01:00.0: Unsupported chipset 0x0c1800a1 [ 4.629270] nouveau 0000:01:00.0: PCI INT A disabled [ 4.629275] nouveau: probe of 0000:01:00.0 failed with error -22 $ dmesg|grep 0000:01:00 [ 1.562570] pci 0000:01:00.0: reg 10: [mem 0xfb000000-0xfbffffff] [ 1.562577] pci 0000:01:00.0: reg 14: [mem 0xf0000000-0xf7ffffff 64bit pref] [ 1.562585] pci 0000:01:00.0: reg 1c: [mem 0xf8000000-0xf9ffffff 64bit pref] [ 1.562589] pci 0000:01:00.0: reg 24: [io 0x2000-0x207f] [ 1.562593] pci 0000:01:00.0: reg 30: [mem 0x00000000-0x0007ffff pref] [ 1.632909] vgaarb: device added: PCI:0000:01:00.0,decodes=io+mem,owns=none,locks=none [ 1.691332] pci 0000:01:00.0: BAR 6: can't assign mem pref (size 0x80000) [ 3.259174] vgaarb: transferring owner from PCI:0000:00:02.0 to PCI:0000:01:00.0 [ 3.468455] nouveau 0000:01:00.0: power state changed by ACPI to D0 [ 4.625468] nouveau 0000:01:00.0: power state changed by ACPI to D0 [ 4.625480] nouveau 0000:01:00.0: enabling device (0104 -> 0107) [ 4.625487] nouveau 0000:01:00.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16 [ 4.625491] nouveau 0000:01:00.0: setting latency timer to 64 [ 4.629190] [drm] nouveau 0000:01:00.0: Unsupported chipset 0x0c1800a1 [ 4.629270] nouveau 0000:01:00.0: PCI INT A disabled [ 4.629275] nouveau: probe of 0000:01:00.0 failed with error -22 # lshw -c video *-display UNCLAIMED description: VGA compatible controller product: nVidia Corporation vendor: nVidia Corporation physical id: 0 bus info: pci@0000:01:00.0 version: a1 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress vga_controller cap_list configuration: latency=0 resources: memory:fb000000-fbffffff memory:f0000000-f7ffffff memory:f8000000-f9ffffff ioport:2000(size=128) *-display description: VGA compatible controller product: Core Processor Integrated Graphics Controller vendor: Intel Corporation physical id: 2 bus info: pci@0000:00:02.0 version: 02 width: 64 bits clock: 33MHz capabilities: msi pm vga_controller bus_master cap_list rom configuration: driver=i915 latency=0 resources: irq:45 memory:fd000000-fd3fffff memory:d0000000-dfffffff ioport:1800(size=8) $ lspci|grep VGA 00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 02) 01:00.0 VGA compatible controller: nVidia Corporation Device 0df0 (rev a1) lspci part about motherboard and BIOS: *-firmware description: BIOS vendor: Phoenix Technologies LTD physical id: 0 version: 6.00 (08/27/2010) size: 116KiB capacity: 4032KiB capabilities: pnp upgrade shadowing escd cdboot bootselect int9keyboard int10video acpi usb agp smartbattery biosbootspecification *-board UNCLAIMED description: Mother Board product: B7130 vendor: CLEVO CO. physical id: 2 version: Not Applicable serial: Not Applicable slot: Not Applicable This machine is based on http://www.clevo.com.tw/en/products/prodinfo_2.asp?productid=300 ./test_off.sh from http://linux-hybrid-graphics.blogspot.com/2010/07 /using-acpicall-module-to-switch-onoff.html yields "failed" for everything. The nVIDIA properitary driver was a disaster, it would left me without a X server and after uninstalling it, I had to reinstall libgl1-mesa- glx and run sudo update-initramfs -u. Not sure if it helped, but I removed newer files (touched by nvidia installer) in /lib/modules/$(uname -r) and reinstalled linux-image-$(uname -r) too (which took care of updating initramfs as well) I've seen this thread as well: http://ubuntuforums.org/showthread.php?t=1657660, so I quited with trying to get the properietary driver to work. The BIOS does not provide me an option for switching/disabling Optimus or video cards (Phoenis SecureCore) Running Kubuntu 10.10 64bits on a laptop.
