Practical guidance for sending low-volume operational email from a Linux server with Postfix, including when to relay instead of sending direct, what current deliverability checks matter, and simple commands for testing.
In my opinion you will get more sucessful boots and reduced graphical errors on boot if you remove quit and splash. Specifically the splash screen can make strange things happen and when removing "quiet" you are able to debug if there is an error.
I also tried to fiddel with "/etc/grub.d/48_linux_zfs" where I tried to out comment #vt_handoff="1" and set quiet boot to zero:
insert: "keycode 49 = less greater backslash backslash backslash" in "$HOME/.Xmodmap" and run "xmodmap .Xmodmap" - this will setup your keys on the system.
To make these keys persistent run: "xkbcomp $DISPLAY $HOME/.xkbmap"
When trying to read any exfat formatted SD card it suddenly was not recognised by my system, so I tried to upgrade from Kubuntu 18.10 to 19.10, and it didn't help. Then I found a post about that Exfat is not supported by the kernel before version 5.4, but Kubuntu 19.10 is shipped with 5.3, but the packages exfat-fuse and exfat-utils should take care of it, but they were already installed and did not work apparently. And also my kernel is 5.0.x for some reason (5.0.0-36-generic).
