Gnome Session
Gnome Session
Show whether you are on wayland or x11:
$ loginctl show-session $(loginctl | grep $(whoami) | awk '{print $1}') -p Type
or
$ echo $XDG_SESSION_TYPE
Switch gui terminal
ctrl + alt + f1
Restart
You can restart the gnome-shell by pressing Alt+F2 and then typing in either "restart" or just "r" and pressing enter.
Software Center History
This app, gnome-software is sorta nice in its GUI flashiness and reminds me of Apple app store. Wouldn’t it be nice to see my history of installations through this tool? In the backend it apparently uses PackageKit. What is odd though is that it doesn’t record history through the dnf tool. So all my command line history is captured but none of the GUI installs are captured. If you need to see packages by installation you need to run through some RPM commands. You might also have this problem when installing RPMs directly, without DNF.
Show DNF history:
# dnf history
Show last install date:
$ rpm -qa --last
Show packages installed, with installation repository:
# dnf list installed
Find packages installed by command line, without DNF:
$ dnf list installed | grep commandline
Find all packages installed by user, whether through DNF or gnome-software:
# dnf history userinstalled
Note that this bug is tracking the fact that gnome-software and PackageKit are not using the DNF history database:
