I am running Ubuntu 18.10 on an i7-8 with 32Gb RAM and an NVIDIA RX-2080. We installed and x failed after a while. I had installed NVIDIA drivers. It seemed like the nouveau driver started running, no idea why. A couple of weeks later the resolution suddenly went to hell one morning, and the machine is barely responding.
Now it happened again. We blacklisted the nouveau driver, still didn't work, re-installed NVIDIA. Now that the machine works again, can anyone explain why this happens, and whether blacklisting is likely to solve this problem? Is there anything else I can do?
If your graphics driver is not getting updated with your kernel, it will stop working after a kernel upgrade and your system will revert to the nouveau or frame buffer drivers to run your video hardware.
This happened to me when I installed drivers by downloading them from the NVIDIA website. To solve the problem I added the Graphics Drivers PPA and installed the NVIDIA drivers through ubuntu-drivers command.
Start by uninstalling your old NVIDIA driver,
and then follow these steps:
1. Add the PPA
2. Install Video Drivers For Your Card
Now as posted in this answer, you need to install the recommended driver for your card.
This will output something similar to this:
Then just install the driver labeled "recommended", so in this example it would be:
Once this is done reboot and you should be good to go. Next time your kernel gets updated, your video driver will get updated with it.
