Software icon (from Sublime Text) isn't displayed in launcher

Question

I can start the software and find it over the dash, but no icon is shown (a blank sheet in the dash and a question mark in launcher). Sublime Text is sitting in /opt/sublime_text/ . sudo sublime /usr/share/applications/sublime.desktop looks as following:

[Desktop Entry]
Version=3.0
Name=Sublime Text 3
# Only KDE 4 seems to use GenericName, so we reuse the KDE strings.
# From Ubuntu's language-pack-kde-XX-base packages, version 9.04-20090413.
GenericName=Text Editor

Exec=sublime
Terminal=false
Icon=/opt/sublime_text/Icon/48x48/sublime_text.png
Type=Application
Categories=TextEditor;IDE;Development
X-Ayatana-Desktop-Shortcuts=NewWindow

[NewWindow Shortcut Group]
Name=New Window
Exec=sublime -n
TargetEnvironment=Unity

I got also a "?" on icons from applications unity wants me to install from firefox (like tumblr, gmail).

Answer 1

For me it helped to simply change a line in /.local/share/applications/sublime_text.desktop

Wrong: Icon=sublime_text.png
Correct: Icon=sublime-text.png

i.e. replace underscore by dash in icon name.

Answer 2

Had exact problem, adding the correct path to executable or softline resolved the issue for me

Exec=/usr/bin/sublime %F

Don't forget to quit and restart sublime for this to get updated.

Answer 3

The only thing that I feel would be wrong is the path.Add a proper path to Exec.

[Desktop Entry]
Version=1.0
Type=Application
Name=Sublime Text
GenericName=Text Editor
Comment=Sophisticated text editor for code, markup and prose
Exec=/opt/sublime_text/sublime_text %F
Terminal=false
MimeType=text/plain;
Icon=sublime-text
Categories=TextEditor;Development;
StartupNotify=true
Actions=Window;Document;

Hopefully this should resolve the issue.
