Mouse and Keyboard power off

Do you use an usb mouse and keyboard and have laptop_mode installed under your Arch linux ? Then maybe you have the same problems as me - mouse and keyboard getting inactive every 2 seconds or so.

To solve this, go to /etc/laptop-mode/conf.d and copy usb-autosuspend.conf to /etc/laptop-mode/conf.d/board-specific. After that run lsusb and get the ID of the usb device you want, e.g., 093a:2500 .

Open the board-specific/usb-autosuspend.conf file and find the AUTOSUSPEND_USBID_BLACKLIST conf option. Put the desired usb IDs there. You might need to run sudo laptop_mode afterwards to reload the configs.

	New functions should accept two arguments, the column to be
	filtered and the currently set filter string, and should
	return True to accept the row, False otherwise.
