Linux kernel 5.4 is very problematic, the installation of NVidia drivers is not working at all. I had to go back to 4.15-generic, as I could not get the drivers to build with the newer Linux kernel version. This is very annoying. The NVidia driver from the website can be installed, but this is more trouble than just installing a proper driver using DKMS from the repositories. That makes installation and removal much easier with Synaptic. But I hope this gets easier in the future. Linux does need easier driver installation to bring in more users. The default nouveau driver for Linux does not work very well for gaming, and the 5.4 kernel does not have very good performance when loading with the nomodeset parameter to the kernel, but 4.15 works perfectly. I do not know why this is, but hopefully, this can be fixed in the future. I do like the hardware support of Linux, but the installation of driver software needs to be made easier for new and old users. In the olden days of Linux, it was easy to install a kernel from Kernel.org from source, then install the NVidia drivers from the downloaded package and get it to compile against the kernel.
What has changed these days? but I managed to remove the NVidia driver package and install a package from the repository and use DKMS to build the driver for 4.15 and this is working. Kernel 5 needs more work to be usable in the long run. The older kernel packages work perfectly, and this is fine for me. Other hardware works perfectly on Linux, even gaming keyboards and mice are detected if only there was an open-source driver available for Linux that could compete with the ease of use of Windows NVidia drivers. But this may not even happen. This is what we need on Linux though, if we could have a proper graphics driver set in the kernel. Then the hardware would work out of the box, with no extra configuration. But unfortunately, we do not have such a luxury at this time. Intel graphics are supported, why not NVidia, what are they scared of, why not take a risk by releasing an open-source driver and get the hardware working o Linux? Are they worried that a competitor will find out their hardware secrets? NVidia have announced the possibility of an open-source driver for 2020, but time will tell if this will really help out Linux support.
The future will be interesting that is for sure.
