I had the same error launching Minecraft on Ubuntu 18.04, but just managed to resolve it by installing an updated version of the (NVidia proprietary) drivers for my graphics card. I was using the (current) standard version from the Ubuntu repo (390.48), but was able to install a more recent one (390.87) from the graphics-drivers/ppa.
