I'm trying to modify my Firefox shortcut in Unity so that it started with a specific parameter. From a terminal, I would start like this:
VDPAU_DRIVER=va_gl firefox
I tried modifying the firefox.desktop
file so that the Exec line looked like
Exec=VDPAU_DRIVER=va_gl firefox
But this doesn't work (the application doesn't start). I thought it could be a problem with two "=" signs, so I tried
Exec="VDPAU_DRIVER=va_gl firefox"
but this doesn't work either. What should I do?
