Issue:

Changed login password via User Manager gui on my XPS 15 running Fedora 29. I noticed that after the next reboot, I get prompted to enter my KDE Wallet password. The only value that works is my previous login password.

Issue1:

I noticed while performing a fresh install of Fedora 29 on my Dell XPS 15 that the keyboard shortcuts to switch to alternate tty session did not work. Control-Alt-4 was the only one that would get me a tty but I could never get back to the Xorg session (control-alt-1 did not work).

Solution1:

This was solved by adding the following as permanent kernel boot parameters in /etc/default/grub and recreating /etc/grub2/grub.cfg (grub2-mkconfig -o /boot/grub2/grub.cfg). Here are the boot parameters that I believe need to be added in the exact order:

acpi_osi=! acpi_osi=Linuxacpi_osi="Windows 2009"
