I am currently having a "small" problem getting my Nvidia drivers to work. It is identical to this post: NVidia X Server Settings GUI doesn't start on ubuntu 18.04

I however have not installed CuDNN and TensorFlow-GPU.

$ uname -a
Linux OVG-HP 4.19.9-041909-generic #201812130432 SMP Thu Dec 13 
09:34:53 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

The error/bug:

$ nvidia-settings

ERROR: Unable to load info from any available system

** Message: 21:50:05.394: PRIME: is it supported? no

I also tried to do nvidia-xconfig:

$ nvidia-xconfig

WARNING: Unable to locate/open X configuration file.

WARNING: Unable to parse X.Org version string.

Package xorg-server was not found in the pkg-config search path.
Perhaps you should add the directory containing `xorg-server.pc'
to the PKG_CONFIG_PATH environment variable
No package 'xorg-server' found

ERROR: Unable to write to directory '/etc/X11'.

Seems to me that I am missing "bunch" of files to run Nvidia driver, even if this is a fresh install of it (was just reinstalling). I have tried searching around for this behaviour but haven't really found much that helps.

Could this be caused of nomodeset in my grub? I noticed that I am also missing some folders from Intel, basically to control the screen brightness. I saw that happen from when I restarted after adding nomodeset to grub. The computer however won't run unless it has nomodeset.

If this is a bug, I will do my best to report it to developers. If not, all help is welcome. :)

This question came from our discussion, support, and feature requests site for Ubuntu users and developers.

  • Where did you install that Kernel from? What version of Ubuntu are you running? Was there a problem with the kernel that comes with the version of Ubuntu you are running? There is a chance that the driver or nvidia-settings may not work with an unsupported kernel version. – Terrance Dec 15 '18 at 4:24
  • I installed it with ukuu. There was nothing "wrong" with the 4.15 kernel, but the difference is that the computer runs colder now (much less ramping up fans). I had the this problem on Ubuntu 18.04 and after my newest reinstall I use Linux Mint 19 (which is a derivative of Ubuntu 18.04). I had EXACT same problem in Ubuntu 18.04. – Ólafur Víðir Guðbjargarson Dec 15 '18 at 7:43
  • Since the Kernel is not a version that is currently supported in the stable releases I would recommend that you file a bug against the driver or the nvidia-settings app for that specific kernel. – Terrance Dec 16 '18 at 5:45
  • Well, I do get exact same results on kernel 4.15 (might have put that better in my question) as on kernel 4.19.9. I have the drivers installed but there seem like there are "bunch" of files missing. – Ólafur Víðir Guðbjargarson Dec 16 '18 at 8:50
  • I found the same problem over here askubuntu.com/questions/1087714/… I had to dig pretty much to find it. – Ólafur Víðir Guðbjargarson Dec 16 '18 at 9:38
