Question about nvidia driver

[emilia at disroot.org]

Hello there,
i have been using the nvidia 340 driver for some time with an older nvidia gpu, now i have a gtx 960 and decided to use the newest nvidia driver.
In order to use X11 I load the nvidia-modeset kernelmodule, X11 works nicely but now all other tty's (0-7) are completely messed up and only show gibberish, is there some fix for that?

regards,
emilia
