xbindkeys claims there is a conflict with another program, which makes it unable to grab all the defined keys

I installed xbindkeys to catch my custom key shortcuts, and xte in order to emulate the key presses i want to execute. This **does** work, but with a lot of issues. I have to press my key combination very many times in order to get it to work once in a while, the success rate on that being about 15% or so. So as recommended by the archwiki , i ran xbindkeys -n to see if any errors are encountered, which gave me the following output: > *** Warning ***\ > Please verify that there is not another program running\ > which captures one of the keys captured by xbindkeys.\ > It seems that there is a conflict, and xbindkeys can't\ > grab all the keys defined in its configuration file. To my knowledge, i haven't installed any software that should conflict with catching pressed keys (at least not on purpose). I am running Xubuntu 20.40, and i don't know if any such software comes with it... If it makes any difference, the keys are all defined with the Super modifier. I did remove all the default shortcuts from XFCE that implement the Super key, from the Keyboard > Application shortcuts, and from the Window Manager > Keyboard entries. How would i check to see what is causing the conflict, and then go about resolving it?
