It seems that go can't get XDG_CURRENT_DESKTOP env when starts from systemd because I do have that env (XDG_CURRENT_DESKTOP=XFCE), it works when run the binary directly. LoL

OS: ArchLinux x64 with xfce4 desktop

[marguerite]

can you please add:
log.Println(os.Getenv(“XDG_CURRENT_DESKTOP”))

before:

de := strings.ToLower(os.Getenv("XDG_CURRENT_DESKTOP"))

run go build again, then the systemd service to check what the log say?

I am on KF5, and it’s good...

I add log.Println("hello" + os.Getenv("XDG_CURRENT_DESKTOP") + ">>"),
and grep the log

Mar 04 20:43:22 ooxx bing-wallpaper[1633]: 2018/03/04 20:43:22 hello>>

My systemd version is 237.64... Tested serveral other env, all is empty. LoL
