FIX ECLIPSE (LUNA) DISPLAY ON UBUNTU 14.04
http://www.kaibader.de/fix-eclipse-luna-display-on-ubuntu-14-04/
In case of starting Eclipse from a console two environment variables need to be set in advance to avoid a corrupted Eclipse window:
export SWT_GTK3=0 export UBUNTU_MENUPROXY=0
In my case I created a desktop entry~/.local/share/applications/eclipse.desktop to facilitate the startup. Adapt it to your needs:
[Desktop Entry] Version=4.4 Name=Eclipse Comment=Eclipse IDE Exec=env UBUNTU_MENUPROXY=0 SWT_GTK3=0 /home/kai/eclipse/eclipse Icon=/home/kai/eclipse/icon.xpm Terminal=false Type=Application Categories=Utility;Application
