Hi all,
I had to format my laptop; now I am not able to install Nvidia as Prime. One of friends in this forum had helped me through the installation process and I was counting on that I was planning to follow the instructions in that topic. But I couldn’t find it. So I tried to do it alone. I dealed with a few errors but I am stuck here:
ERROR: Unable to load the kernel module ‘nvidia-uvm.ko’. This happens most frequently when this kernel module was built against the wrong or improperly configured kernel sources, with a version of gcc that differs from the one used to build the target kernel, or if another driver such as nouveau, is present and prevents the NVIDIA kernel module from obtaining ownership of the NVIDIA GPU(s), or no NVIDIA GPU installed in this system is supported by this NVIDIA Linux graphics driver release.
Please see the log entries “Kernel module load error” and “Kernel messages” at the end of the file “/var/log/nvidia-installer.log” for more information.
And this is the log file:
Please see the log entries 'Kernel module load error' and 'Kernel messages' at the end of the file '/var/log/nvidia-installer.log' for more information.
**-> Kernel module load error: No such file or directory**
ERROR: The nvidia-uvm kernel module failed to load. This kernel module is required for the proper operation of CUDA. If you do not need to use CUDA, you can try to install this driver package again with the '--no-unified-memory' option.

ERROR: Installation has failed. Please see the file '/var/log/nvidia-installer.log' for details. You may find suggestions on fixing installation problems in the README available on the Linux driver download page at www.nvidia.com.
So, kernel module says, “No such file or directory” Whats that supposed to mean?
And finally, steps I did:
-
Fresh install
-
Created a
blacklist.conffile containing:blacklist vga16fb blacklist nouveau blacklist rivafb blacklist nvidiafb blacklist rivatv -
sudo systemctl disable sddm
-
Restart
-
account login on black screen. You call it TTY or something
-
cd to Nvidia.run file and sudo sh nvidia.run
-
Dealed with a few errors
-
Stucked at final error I mentioned.
Your help is greatly appreciated
