I installed Mathematica 9 and 10 on Ubuntu Linux 14.04 with Unity. How to set icons for them? At the moment they show up as gray squares with a question mark in it on the dock.

Well I solved it this way:
Go to:
/usr/local/Wolfram/Mathematica/9.0/SystemFiles/FrontEnd/SystemResources/X/
(or wherever your local mathematica installation is located)
From there move the 32x32, 64x64 and 128x128 .png icon files into the respective
/usr/share/icons/hicolor/32x32/apps
/usr/share/icons/hicolor/64x64/apps
/usr/share/icons/hicolor/128x128/apps
folders, but giving them respectively the same name (such as wolfram-mathematica9.png).
Then edit the file:
/usr/share/applications/wolfram-mathematica9.desktop
change the line corresponding to Icon:
Icon=wolfram-mathematica9
(without the png extension)
If that file is not present in /usr/share, copy it from here:
/usr/local/Wolfram/Mathematica/9.0/SystemFiles/Installation/wolfram-mathematica9.desktop
Remember: You need sudo permissions to run these commands.
To be sure, you can run
sudo updatedb
then reboot and it should work now.

$\begingroup$ That doesn't work for MMA 10.4.1 under Linux Mint 17.3 Cinammon. Is there a way to fix it? $\endgroup$– corey979Commented May 9, 2016 at 12:44

$\begingroup$ Mathematica 10.4.1.0 on Ubuntu seems to have proper icon from the start. $\endgroup$– krokodilCommented May 14, 2016 at 23:50

$\begingroup$ I wanted to start Mma directly from the whiskermenu rather than from there through another submenu with only a single choice. Clicking on the left upper square in Xfce's launcher properties, setting command to /usr/local/Wolfram/Mathematica/10.1/Executables/Mathematica %F and the symbol to /usr/share/icons/hicolor/64x64/apps/wolfram-mathematica.png worked fine for me. Thank you for this hint. I would not have searched in /usr/share/icons/hicolor/64x64/apps - what a long path! How did you get that? $\endgroup$ Commented Oct 26, 2016 at 15:02

$\begingroup$ @AdalbertHanßen that's the standard directory where third-party applications put their icons. $\endgroup$ Commented Nov 15, 2016 at 16:28
