The graphical auto shutdown app KShutdown released version 5.90 with feature to reboot from Linux into another OS automatically.

KShutdown is a free open-source app that provides a simple Qt based user interface. It allows users to automatically shutdown, restart, hibernate, sleep, log-out, or run a command on certain time, after a period of time, on user inactivity or other event.

The app is getting more and more powerful. The latest 5.90, beta for next 6.0 release, introduced experimental multi-booting support. User can now automatically reboot from Linux into another OS, such as Windows, from Grub menu entries.

The new feature needs administrator user privilege to get access ‘/boot/grub/grubenv’. The app however does not apply it properly so far, and user need to start it manually via sudo kshutdown from command line.

And it does not read the Grub menu automatically, though it can be set manually in ‘Tools -> Configure KShutdown -> Restart’. Use the app ‘Grub Customizer’ to get the menu entries.

Other features in KShutdown 5.90 include:

• Add “File Monitor” trigger (detects a file remove/create).
• New configurable global shortcuts to show/hide main window, actions window.
• Add more “journalctl” commands in ‘Tools -> Run’ menu.
• Basic Qt 6 support.
• Add Help → System Information menu to show basic system and app info.
• Various minor UI tweaks and improvements.
• And various bug-fixes.
