Nvidia 340.108 OpenSuse 15.2 black screen text TTYs after suspend


After resuming from suspend mode, text TTYs ( ctrl - alt f1 to f6 ) are black. Before suspend mode work normaly. nouveau driver blacklisted.

My kernel params : video=vesa:off vga=normal

Is there any solution to solve ? Thanks !

I use KDE plasma for desktop. If I set Xrender engine for compiositor, resume is normal for graphics mode. Aftrer resume lock screen is started. If I try openGL 2.X , I get Xorg crash.
