Correct nvidia+intel graphics setup in 14.04

Question

Just upgraded to 14.04 to try to fix some other issues. Now, something has gone wrong with my graphics.

I have a Thinkpad T530 with Intel and Nvidia graphics cards.

$ inxi -SGx
System:    Host: xyz Kernel: 3.13.0-24-generic x86_64 (64 bit, gcc: 4.8.2) Desktop: N/A Distro: Ubuntu 14.04 trusty

I'm not sure what I did but now something is wrong with my graphics, as should be visible from the above commands. nvidia-detector says "none" as well.

I used to have bumblebee but then some website said to remove it and now something's clearly wrong. What's the right way to set things up? Should I try to add bumblebee back?

Here's what's installed now:

$ dpkg --get-selections | grep nvidia
nvidia-319                  install
nvidia-331                  install
nvidia-libopencl1-331               install
nvidia-opencl-icd-331               install
nvidia-prime                    install
nvidia-settings                 install
nvidia-settings-319             install

Solution

Before you proceed with the following please consider removing other nvidia drivers that might conflict.

For the latest proprietary Nvidia driver the following commands may be issued :

sudo apt-add-repository ppa:xorg-edgers/ppa
sudo apt-get update
sudo apt-get install nvidia-current nvidia-settings

For Nvidia Optimus technology (Nvidia+Intel) and the benefit of Bumblebee features the following must be issued :

sudo add-apt-repository ppa:bumblebee/stable
sudo apt-get update
sudo apt-get install bumblebee bumblebee-nvidia

A final tip is to remember using optirun command in prefix of the 3D software command

optirun somegame-or-command

You can also test 3D with the following commands

glxspheres 
optirun glxspheres

There was a build error in one of the kernel modules: ` CC [M] /var/lib/dkms/vboxhost/4.2.18/build/vboxdrv/r0drv/linux/memo‌​bj-r0drv-linux.o /var/lib/dkms/vboxhost/4.2.18/build/vboxdrv/r0drv/linux/memo‌​bj-r0drv-linux.c: In function ‘rtR0MemObjNativeMapUser’: /var/lib/dkms/vboxhost/4.2.18/build/vboxdrv/r0drv/linux/memo‌​bj-r0drv-linux.c:153‌​9:26: error: ‘struct mm_struct’ has no member named ‘numa_next_reset’ pTask->mm->numa_next_reset = jiffies + 0x7fffffffffffffffUL; ^ ...`

Which caused: Error! Bad return status for module build on kernel: 3.13.0-27-generic (x86_64)

[Espressofa]

Also, glxinfo reports the same thing.

Did you copy the full line?

[Espressofa]

Yeah. I installed bumblebee again and that seems to have restored things to the way they were. But is that wrong for 14.04?

[Korkel]

No, that is not wrong.

[Espressofa]

I'll give this a shot.

When I try an optirun command: $ sudo optirun firefox [sudo] password for xyz: [ 526.850214] [ERROR]Cannot access secondary GPU - error: [XORG] (EE) intel(0): [drm] failed to set drm interface version: Permission denied [13]. [ 526.850286] [ERROR]Aborting because fallback start is disabled.

But this might have fixed some other issues I was having.

Did you purge the older nvidia packages ? "sudo apt-get purge packages" instead of "sudo apt-get remove packages" to remove configuration files? I think you can still reconfigure nvidia anyway with the following command "sudo nvidia-xconfig" See if this fixes your problem. You can also test 3D with the following "glxspheres" and "optirun glxspheres"

[Espressofa]

I don't have nvidia-xconfig, unfortunately. Do you know what package provides that?
