I’m facing a problem while using spark. my spark not opening in Linux. when someone messages me then I’m able to see the message but the spark is not completely open. only I can see messages. I also tried uninstalling spark. but when I uninstall spark from Linux, I still get the message from a spark. I don’t know how? …
Very likely you messed up permissions by running sudo stuff on GUI app.
Either manually change files (especially config files) from root to current logged in user.
Or completely uninstall and remove all files and reinstall Spark and open it this time from normal menu!
