Running an app from menu vs terminal

Hi,

Just bumped into a problem, maybe something related to file ownership. I need to start Skypeforlinux on my box with preloading of the library which flips the image (my webcam is installed upside-down).
So when I run this from terminal:

LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libv4l/v4l1compat.so /usr/bin/skypeforlinux

everything is OK, Skype starts, image is correct (which means preloading works, because without it the picture is upside-down).
But if I edit the entry in the Main Menu with exactly the same command, I get this error:

Failed to execute command "LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libv4l/v4l1compat.so /usr/bin/skypeforlinux".
Failed to execute child process "LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libv4l/v4l1compat.so" (No such file or directory)

What might be a problem?

Thank you.

Re: Running an app from menu vs terminal

The Exec line in the .desktop file doesn't understand parameters, try this command instead:

sh -c "LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libv4l/v4l1compat.so /usr/bin/skypeforlinux"
