Nvidia 390 drivers stopped working with kernel 5.5 and probably also Nvidia 340. I was unable to get Nvidia-390 drivers to work with new kernel 5.5. Other people look to have the same problems. I posted here: https://bugzilla.rpmfusion.org/show_bug.cgi?id=5536 and other people confirm, there are more links to Nvidia forums.
If everyone with 390 and 340 drivers are unable to use kernel 5.5, what it will mean?
