How to Restart Ubuntu Linux: A Complete Guide
Restarting Ubuntu Linux clears your computer’s temporary memory and closes open apps to fix glitches or finish system updates. You can restart your system in 3 main ways: using the desktop menu, typing a command in the terminal, or pressing the physical power button on your PC.
Typing the command sudo reboot into the terminal shuts down your system right away, though this method needs administrator permission. If you prefer using your mouse, click the system status area in the top-right corner of your screen, pick the power icon, and choose the restart option from the menu.
Restart Ubuntu Linux using the system menu by clicking the top-right status area, selecting the power icon, and choosing “Restart.” Alternatively, open a terminal and type `sudo reboot` or `sudo shutdown -r now`.
How to restart Ubuntu Linux from the system menu
You can restart Ubuntu Linux using the system menu when your desktop is frozen or you need to finish applying updates. Click the top-right corner of your screen, open the power options, and select the restart option to safely reboot your computer without using the command line.
To restart in Ubuntu Linux, click the top-right of the system menu, then choose Power Off / Log Out to expand the context menu .
Select ‘Restart’ from the expanded menu, and then click the ‘Restart’ button.
Restart Ubuntu Linux from the command line
Keyboard shortcuts offer a quicker route for command-line users. Press Ctrl+Alt+T to open the terminal, then run the necessary commands to reboot.
sudo shutdown -r now
Scheduled reboots use the 24-hour format with the shutdown command, matching this example for 5:00 PM:
sudo shutdown -r 17:00
Delaying the shutdown process allows the system to wait a set number of minutes before powering down. Run the command options below:
sudo shutdown -r +15
Restart Ubuntu Linux using the PC Power button
You can restart Ubuntu Linux using the physical power button on your computer case when the desktop interface stops responding entirely. Pressing the power button triggers a safe shutdown or reboot on most modern hardware, acting as a reliable backup when software menus fail.
Routine shutdowns benefit from software controls rather than hardware switches.
