After updating my Kali Linux operating system with the GNOME interface, I encountered issues where several shortcuts and features were missing. Despite attempting to troubleshoot and resolve the problem through various methods, such as adjusting settings, display configurations, leafpad settings, brightness controls, and other relevant adjustments, I couldn't find a solution. These missing features and shortcuts have significantly impacted the usability and functionality of the system. Additionally, the battery percentage is not showing, and sometimes the Firefox search engine is not working properly.
