Image When Ur Linux OS freezes completely,
Press and hold Alt + PrintScreen(SysReq) keys and simultaneously type REISUB


THIS WILL REBOOT UR LINUX SAFELY,
HERE WE ARE PASSING PARAMETERS DIRECTLY TO KERNEL

  • R: Switch the keyboard from raw mode to XLATE mode
  • E: Send the SIGTERM signal to all processes except init
  • I: Send the SIGKILL signal to all processes except init
  • S: Sync all mounted filesystems
  • U: Remount all mounted filesystems in read-only mode
  • B: Immediately reboot the system, without unmounting partitions or syncing
This Method Should be attempted only if Alt+Backspace fails
