Linux - Mint doesn't wake up after screen is locked and blank

Be careful, this is only a work around.


This feature is a part of usbcore which is compiled in the kernel.

From https://unix.stackexchange.com/a/175035.

• Edit
• /etc/default/grub 
• Change 
• GRUB_CMDLINE_LINUX_DEFAULT 
• Add this option at the end
• usbcore.autosuspend=-1
• That's the result 
• GRUB_CMDLINE_LINUX_DEFAULT="quiet splash usbcore.autosuspend=-1" 
• Save the file and update grub
• sudo update-grub 
• Reboot
  

    Now, if you check the autosuspend value with 

• cat /sys/module/usbcore/parameters/autosuspend

    it should display -1.
