Timekpr-nExT is graphical parental control tool for Linux, useful if you want to limit child activity on a computer. The application, which uses Python / GTK3, works with multiple desktop environments, including GNOME, Xfce, Cinnamon, KDE Plasma, Unity, Deepin and Budgie, under both X11 and Wayland. The application can limit computer usage for some user accounts by setting predefined access rules. You can set daily computer time usage limits -- either by setting the number of hours/minutes per day an account can have access to the computer, or by specifying an hour interval. You may also specify weekly and monthly computer usage limits. After the time expires, the user is automatically logged out.
