Ubuntu 15.10 nVidia Driver Problem

**gfb-gokberk** · October 6th, 2015

Hello, I installed Ubuntu 15.10 beta 2. When I try to install additional nVidia drivers [[version 355.11 from nvidia-355 (open source) and -version 352.41 from nvidia-352 (proprietary)]], after reboot, i see only black screen. The only thing that i can do, return to nouveau drivers.

What is the correct configuration?

I have two graphic cards. Intel HD4600 and GeForce 840M

Code:

lspci | egrep "VGA|3D|Display"

Code:

00:02.0 VGA compatible controller: Intel Corporation 4th Gen Core Processor Integrated Graphics Controller (rev 06)
01:00.0 3D controller: NVIDIA Corporation GM108M [GeForce 840M] (rev a2)

Also i installed Bumblebee and when i do this for example;

Code:

optirun google-chrome

i get this:

Code:

[ 2105.171956] [ERROR]Cannot access secondary GPU - error: Could not load GPU driver

[ 2105.172126] [ERROR]Aborting because fallback start is disabled.

Code:

dpkg -l | egrep "nvidia|bumblebee|prime"

Code:

Are you trying to use the dual screen option? because I think that there were problems with this and may be dealt with during next development cycle. Otherwise it should jockey with nouveau but not nvidia.

**dino99** · October 6th, 2015

why opting for "do not use the device" ? you might accept the line above (microcode)
open-source is "nouveau", not a nvidia driver

the intel graphic needs xserver-xorg-video-intel driver to be able to work

There shouldn't be a problem with dual screens, as I can use both monitors with nouveau and the Nvidia proprietary drivers. I'm running a 32" Samsung TV and a Benq 22" with zero problems. I'm running the Nvidia 340.93 version from the repositories.

If you want to use only the Intel or only the Nvidia and can disable one or the other in BIOS, then Bumblebee is not needed. The appropriate Intel driver will be used automatically if Intel video is detected as active. Tthe Nouveau driver will be used if the Nvidia is active. You can then, in that instance, if you wish, use Additional Drivers to install a proprietary driver from Nvidia.

But are they two different chipsets? ie: 1 Intel 1 nvidia ?

A quick test here on an optimus device shows bumblebee is broken, same errors (never liked or used bumblebee any way.

nvidia-prime can work well though you'll likely black screen at either any lightdm greeter or on session login.
If that is the case there is no forthcoming fix but quite easy to work-around in several ways. If you need a workaround then post in this thread, mention whether you login to the greeter screen or auto login to the session.

(- I've opted for auto-login & a startup script, that way no black screen & no blind login

As far as nvidia drivers - 304 can't be used with nvidia-prime, 352 is a terrible driver, best option is 355 from the ppa

Hi.

I installed xubuntu 15.10, on my asus with 650m optimus. Got the login screen, and then a black screen after login. My solution:

After getting the black screen I hit:

CTRL+ALT+F1, then logged in.

then:

sudo nano /etc/X11/xorg.conf

In the first section I changed:

Code:

Section "ServerLayout"
    Identifier "layout"
    Screen 0 "nvidia"
    Inactive "intel"
EndSection

to:

Code:

Section "ServerLayout"
    Identifier "layout"
    Screen 0 "intel"
    Inactive "nvidia"
EndSection

Switching the target of "Screen 0" and "Inactive", is the important part here.

After a reboot, I logged in just fine. But when I went to the nvidia-settings, nvidia was set to active, but after setting intel be active, everything behaved just as expected.

Hope it does you some good.

Cheers.

if you are using optimus you don't load the nvidia drivers , everything is setup to use the intel ones and the nvidia driver (in my case nvidia_346_updates to run my GeForce GT 750M) just gets enabled automagically when applications do 3d stuff. You need to install nvidia-prime for this to work.
This breaks some apps that check for nvidia drivers using the filesystem instead of the api
