Hallo zusammen,
 
ich hab noch 2 Problemchen die könnten aber auch zusamen gehören. Es kann auch sein, daß das 2 Problem schon bissl älter ist, das will ich nicht ausschließen.
 
1 Boot auf dem neusten Kernel 5.7.0-1 dann stoppt der Rechner bei Starting Terminate Plymouth Boot Screen...
da gibt google nicht allzuviel verwertbares her irgendwie Keine Ahnung was ich tun kann mit frm Kernel 5.5.0-1 habe oich das Problem nicht.
 
2. Ein Firmware Problem mit Nividia 
 
die Eingabe update-initramfs -u erzeugt die folgende Ausgabe
 
root@dell7720:/home/ottmar# update-initramfs -u                                
update-initramfs: Generating /boot/initrd.img-5.7.0-1-amd64

Ich hab dann mal eine Stichprobe gemacht ob die Dateien da sind
 
root@dell7720:/home/ottmar# find / -name  desc.bin -print
/usr/lib/firmware/nvidia/gv100/sec2/desc.bin
/usr/lib/firmware/nvidia/gp107/sec2/desc.bin
/usr/lib/firmware/nvidia/gm20b/pmu/desc.bin
/usr/lib/firmware/nvidia/gp10b/pmu/desc.bin
/usr/lib/firmware/nvidia/gp102/sec2/desc.bin
/usr/lib/firmware/nvidia/gp104/sec2/desc.bin
/usr/lib/firmware/nvidia/gp106/sec2/desc.bin
/usr/lib/firmware/nvidia/gp108/sec2/desc.bin
 
Dateien mit dem Dateinamen sind da, ob in der richtigen Version ist ne andere Frage, die Pfade sind nicht da.
 
zuerst habe ich gedacht das sind zweierlei Pfade aber /lib ist ein gelinktes /usr/lib
lrwxrwxrwx   1 root root     7 20. Mär 22:16 lib -> usr/lib
 
Also gut das entsprechende Firmware-package ist zu ergoogeln oder ermitteln beim Versuch das nachzuinstallieren kommt die Meldung daß das Paket schon installiert ist.
Auch mit apt-cache search kann man etwas finden. Wenn auch in diesem Falle nichts Verwertbares ^^
Bei den beiden Realteks ist es das Gleiche die Firmware-Packages sind installiert.
 
So ernsthaft habe ich keinen Ansatz was ich tun kann.
