Nvidia GT740M + Intel

[mmax]

Hi,

I can't get my NVIDIA GeForce GT 740M running with Linux Mint 17 and need help. It did work about two weeks ago but since a dist-upgrade it doesn't. I tried the bumblebee package with the nvidia-331 drivers but when I start cinnamon I get the message "Running in software rendering mode" and I don't get any hardware accelleration any more.

Here are some informations:

I allready struggle around a while with this problem - Any Ideas how to fix it?

Thanks,

OK ... i removed the bumblebee stuff and try to get my X.org running without it.

These are the nvidia packages I have installed:

Code: Select all

ii  nvidia-331                                  331.38-0ubuntu7.1                                   amd64        NVIDIA binary driver - version 331.38
ii  nvidia-331-uvm                              331.38-0ubuntu7.1                                   amd64        NVIDIA Unified Memory kernel module

ii  nvidia-prime                                0.6.2linuxmint1                                     amd64        Tools to enable NVIDIA's Prime
ii  nvidia-settings                             331.20-0ubuntu8                                     amd64        Tool for configuring the NVIDIA graphics driver

But I guess It's a problem of th BusID for the nvidia driver - if I set it to "PCI:1@0:0:0" the driver gets loaded but doesn't find a valid display device - see this Xorg.0.log
If i set it to something else or comment it out - It says "(EE) No devices detected" - see this Xorg.0.log

Here is what I allready tried:

Code: Select all

Section "Device"
    Identifier     "Device0"
    Driver         "nvidia"
    VendorName     "NVIDIA Corporation"
    BoardName      "GeForce GT 740M"
#    BusID          "PCI:0@0:2:0"  # No devide found
#    BusID          "PCI:0:1:0"    # No device found
#    BusID          "PCI:1@0:0:0"  # High CPU load - Treiber wird geladen
#    BusID          "PCI:2@0:0:0"
#    BusID         "PCI:1@0:1:0"
    Option         "NoLogo" "true"
    Option         "ConstrainCursor" "off"
    Option         "UseEDID" "false"
    Option         "UseDisplayDevice" "none"
EndSection

Any Ideas what has to be the right BusID?

i made a thread on getting nVidia cards running... plus fan control!

let me know if that gets you running.

[mmax]

Yes, I allready tried that but still no success.

If I set the BusID in the Device section in xorg.conf to "PCI:1:0:0" the driver is loaded but can't find a valid display and the Xorg server runs at 100% CPU usage:

Yep ... now it's working. I had to reinstall the intel drivers as well (purged them before) - described in this post.
Now my xorg.conf looks like this:

Code: Select all

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

Section "Device"
    Identifier "intel"
    Driver "modesetting"
    BusID "PCI:0@0:2:0"
EndSection

Section "Screen"
    Identifier "intel"
    Device "intel"
EndSection

Section "Device"
    Identifier "nvidia"
    Driver "nvidia"
    BusID "PCI:1@0:0:0"
    Option "ConstrainCursor" "off"
EndSection

Section "Screen"
    Identifier "nvidia"
    Device "nvidia"
    Option "AllowEmptyInitialConfiguration" "on"
    Option "IgnoreDisplayDevices" "CRT"
EndSection

glad you got it working...

There is just one more thing. gpu-manager overwrites my custom xorg.conf file and if I deactivate gpu-manager via kernel boot option, my graphics don't work any more. Is there a way to start gpu-manager but disable overwriting the xorg config file?

[Ph0z3]

not that I am aware of. Sorry man.

[roblm]

mmax,

If the BIOS has an option to disable Optimus, then the Nvidia GPU can be selected, and that non-editable xorg.conf file won't
automatically be created.

Do you need to use the Nvidia driver? For most people, the nouveau driver should perform adequatly, and that file won't be created.

If your custom xorg.conf file has Monitor sections, then they can be added to a separate file. What can be added depends on whether
the Nvidia proprietary driver or the nouveau driver is enabled.
Can you post the custom file.

[mmax]

@roblm: My Bios doesn't offer that option

The strange thing is that the gpu-manager replaces my xorg.conf file but it basically is the same. If I log in the first time, cinnamon shows the message that it has crashed and nvidia is not working properly but if I logout and in again, everything works. Any Idea why?

[Ph0z3]

once it does that, drop back to TTY mode, then enter in terminal run: "sudo nvidia-xconfig" the "sudo reboot"

...once rebooted, "sudo nvidia-settings" ...set everything up and save the xConfiguration file.

[mmax]

I dont't even have to switch to TTY .. I just need to logout to mdm and log in again.
It also works if i switch to TTY before logging in, restart mdm and log in afterwoods.
The xorg.conf is ok even when it's overwritten from gpu-manager.

Isn't that a bit strange?

a bit... yeah.

mmax,

Here's some methods you can try to correct the startup problem you're having. Add these two xrandr commands to “/etc/mdm/Init/Default”. Open the file with this command in the Terminal:

Code: Select all

gksudo gedit /etc/mdm/Init/Default

Add these lines at the bottom, just above the last line that says “exit 0”:

Code: Select all

xrandr --setprovideroutputsource modesetting NVIDIA-0
xrandr --auto

Save the file and reboot. If there is a startup problem, then at the GRUB boot menu select Recovery Mode. If no menu shows, then hold down the Shift key while starting. In the menu, select “root - drop to root shell prompt”. When asked for the root password, just type your user password. Then change the file permissions to read and write by typing:

Code: Select all

mount -o remount,rw /

Then open the edited file by typing:

Code: Select all

nano /etc/mdm/Init/Default

Use the Arrow keys to go to the bottom of the file and remove the two lines.

Press Ctrl+X. Type “Y” for Yes. Press Enter. Then type “reboot”. You'll go back to the Recovery Mode menu. Don't click anything, just wait about 7 seconds for the reboot.

If that fails, then try this. Open the xorg.conf file and change this section:

Code: Select all

Section "Device"
    Identifier "intel"
    Driver "modesetting"
    BusID "PCI:0@0:2:0"
EndSection

To this:

Code: Select all

Section "Device"
    Identifier "intel"
    Driver "intel"
    BusID "PCI:0@0:2:0"
EndSection

Then open the “/etc/mdm/Init/Default” file and add these two lines, as done above:

Code: Select all

xrandr --setprovideroutputsource Intel NVIDIA-0
xrandr --auto

It there is a problem after saving and rebooting, then open the xorg.conf file in Recovery Mode with this command:

Code: Select all

nano /etc/X11/xorg.conf

and change this line:
Driver "intel"

to this:
Driver "modesetting"

Then repeat the other steps above in Recovery Mode.

If that fails, then it may be better to do a reinstallation of Mint.
