ERROR: Unable to load info from any available system

could you plz recommend me smth?

[generix]

secureboot: Secure boot enabled

Please try disabling secure boot in bios

Thx. It hepled!

Could you pls describe how did you find this solution?
Is it a common problem with drivers+secure boot?

[generix]

The logs contain the output of
lspci -k
which lists modules available and modules in use. nvidia was available but not used (and also no other one), which has three posible reasons, from most to least common:

1. secure boot enabled and module is unsigned
2. module is blacklisted
3. module is incompatible

So first search fore “secure” in dmesg output leads to the message. (sudo dmesg |grep -i secure)

Interesting!

Thank you!
