Recent Cuda+Nvidia driver on bumblebee system breaks x-server, here's a workaround

SJLPHI · November 23, 2019, 5:57pm

Hello,
I have a Cuda+Nvidia+Bumblebee setup in my laptops, and there was an official cuda update supported for OpenSUSE LEAP 15.0+. If you use the default version in the repository and associated Nvidia driver, the X-server becomes broken.

Thankfully from experience I found out what it was and I was able to fix it. Here’s what to check first:

startx

and check the error code, in my case, there was an error in reading one of the entries in

/etc/X11/xorg.conf.d

At this Nvidia update, for some reason the driver updates and installed:

90-nvidia.conf.

I deleted it and re-compiled kernel by:

sudo mv /etc/X11/xorg.conf.d/90-nvidia.conf/ ~/ 
sudo mkinitrd

I just wanted to share for the sake of documentation and beginners using similar setup.

There seems to be a more serious issue that I need to resolve. It seems that intel integrated GPU is not being loaded properly.

I installed xf86-video-intel

sudo zypper in xf86-video-intel

and the xorg log shows the following:

For an odd reason, I can no longer run Steam with intel card, then pipe games through bumblebee.

When I try to launch steam using intel card, I get the following error:

OpenGL GLX extension not supported by displayMain.cpp (332) : Assertion Failed: Fatal Error: OpenGL GLX extension not supported by display
Main.cpp (332) : Assertion Failed: Fatal Error: OpenGL GLX extension not supported by display

but I can still launch steam from

optirun steam

Another development is that anything that requires compositor such as opening and closing Application Launcher menu takes almost 1 second instead of instantaneous response.

Any suggestions?

Summary:

You need the new nvidia configuration file created during installation gone:


sudo rm /etc/X11/xorg.conf.d/90-nvidia.conf/
sudo mkinitrd

You need to re-set the default libglx provided by xorg:

sudo update-alternatives --config libglx.so

and choose

/usr/lib64/xorg/modules/extensions/xorg/xorg-libglx.so

Just to make sure that this libglx stays as automatic default, set its priority higher than one provided with Nvidia.

sudo update-alternatives --install /usr/lib64/xorg/modules/extensions/libglx.so libglx.so /usr/lib64/xorg/modules/extensions/xorg/xorg-libglx.so  120

The end result should look like this:


~> sudo update-alternatives --config libglx.so
There are 2 choices for the alternative libglx.so (providing /usr/lib64/xorg/modules/extensions/libglx.so).

  Selection    Path                                                        Priority   Status
