After backing up the old dropbox libGL, of course. What it does is force dropbox to use the libGL installed on your system after nvidia overwrites it, by placing a symbolic link to the nvidia libGL in place of the one dropbox was installed with. Hopefully this helps, this worked for me. (so basically: ln -sf /usr/lib/nvidia-/libGL.so.1 ~/.dropbox-dist//libGL.so.1 the version number may change, and may have to be modified when you type it into the terminal $ cd ~/.dropbox-dist/dropbox-lnx.x86_64-3.4.6/Ĥ) backup your's dropbox OpenGL library: $ mv libGL.so.1 libGL.so.1_backupĥ) make symbolic link to nvidia's OpenGL library.: $ ln -sf /usr/lib/nvidia-331/libGL.so.1 libGL.so.1 with dropbox 3.4.6 this is in the home directory. Take note of libGL.so.1 inside this folderģ) find dropbox system library. Ģ) find your nvidia system folder: in my systems it's /usr/lib/nvidia-331 (if you using another version of nvidia driver, for instance nvidia-340, your directory should be /usr/lib/nvidia-340). If you disable an application icon in the System Tray by right clicking it.

This workaround works for me on kubuntu 14.04. An area on the right side of the Taskbar on the Windows interface used.

This happens because nvidia driver overrode OpenGL library (libGL.so). (Are you using nvidia drivers? from, slightly updated)
