Check the desktop environment in Linux, and view the desktop environment in linux

Linux desktop systems include gnome, kde, mate, cinnamon, lxde, xfce, and jwm. Common examples are gnome, kde, and xfce. So how can we determine which desktop environment components are installed in Linux? The following describes how to check the desktop environment:

Method 1: env | grep reply top_session = or echo $ reply top_session

This command can only be executed in the startup command window of the desktop system after entering the desktop system. You can use the SecureCRT tool to connect to the system. If you run this command, no results will be obtained.

Method 2: echo $ GDMSESSION

This command can only be executed in the startup command window of the desktop system after entering the desktop system. You can use the SecureCRT tool to connect to the system. If you run this command, no results will be obtained.

I tested two desktop environments (KDE and GNOME), but I don't know whether it is OK in other desktop environments. The two commands cannot be displayed in some desktop environments.

Method 3: run the ps command to check whether the desktop environment is installed.

3.1: No desktop components are installed

[root@testlnx01 ~]# runlevel

N 3

[root@testlnx01 ~]# ps -A | egrep -i "gnome|kde|mate|cinnamon|lx|xfce|jwm"

3.2: gnome Desktop components installed

[root@localhost ~]# ps -A | egrep -i "gnome|kde|mate|cinnamon|lx|xfce|jwm"

 2304 ?        00:00:00 gnome-keyring-d

 2314 ?        00:00:00 gnome-session

 2352 ?        00:00:00 gnome-settings-

 2377 ?        00:00:00 gnome-panel

 2408 ?        00:00:00 gnome-power-man

 2420 ?        00:00:00 polkit-gnome-au

 2430 ?        00:00:00 gnome-volume-co

 2448 ?        00:00:00 gnome-screensav

 2497 ?        00:00:01 gnome-terminal

 2500 ?        00:00:00 gnome-pty-helpe

Pgrep-l "gnome | kde | mate | cinnamon | lxde | xfce | jwm"

Ps-A | egrep-I "gnome | kde | mate | cinnamon | lxde | xfce | jwm"

Use the ps command or pgrep command

[root@localhost ~]# ps -A | egrep -i "gnome|kde|mate|cinnamon|lx|xfce|jwm"

 2304 ?        00:00:00 gnome-keyring-d

 2314 ?        00:00:00 gnome-session

 2352 ?        00:00:00 gnome-settings-

 2377 ?        00:00:00 gnome-panel

 2408 ?        00:00:00 gnome-power-man

 2420 ?        00:00:00 polkit-gnome-au

 2430 ?        00:00:00 gnome-volume-co

 2448 ?        00:00:00 gnome-screensav

 2497 ?        00:00:01 gnome-terminal

 2500 ?        00:00:00 gnome-pty-helpe

[root@localhost ~]# pgrep -l  "gnome|kde|mate|cinnamon|lx|xfce|jwm"

2304 gnome-keyring-d

2314 gnome-session

2352 gnome-settings-

2377 gnome-panel

2408 gnome-power-man

2420 polkit-gnome-au

2430 gnome-volume-co

2448 gnome-screensav

If I unregister a user from the desktop environment and exit, as shown below, you will see that the process displayed by the same command is obviously less

[root@localhost ~]# pgrep -l  "gnome|kde|mate|cinnamon|lx|xfce|jwm"

2882 gnome-session

2890 gnome-settings-

2909 polkit-gnome-au

2911 gnome-power-man

[root@localhost ~]# ps -A | egrep -i "gnome|kde|mate|cinnamon|lx|xfce|jwm"

 2882 ?        00:00:00 gnome-session

 2890 ?        00:00:00 gnome-settings-

 2909 ?        00:00:00 polkit-gnome-au

 2911 ?        00:00:00 gnome-power-man

[root@localhost ~]# 

Method 4: yum grouplist | more check
