Personally, I would not expect this to be related to mainboard firmware/bios |
40 |
issues as I have not had any issues with efifb and nvidia-drivers on several |
41 |
systems. |
42 |
|
43 |
What is your kernel-commandline? |
44 |
|
45 |
Mine is really simple: |
46 |
$ cat /proc/cmdline |
47 |
root=/dev/nvme0n1p3 |
48 |
|
49 |
I get the following in my dmesg for "efifb": |
50 |
==== |
51 |
[ 8.717047] efifb: probing for efifb |
52 |

Which is nowhere near the real resolution my screen can handle, but for |
60 |
emergencies, this is definitely sufficient. |
61 |
|
62 |
For completeness, these are the entries for nvidia: |
63 |

On a side-note, anyone know how to prevent these sound-devices from appearing? |
89 |
I never use these on this system. |
