cat: /sys/class/backlight/gmux_backlight: Is a directory /bin/sh: 2: intel_backlight/max_brightness: not found cat: /sys/class/backlight/gmux_backlight: Is a directory /bin/sh: 2: intel_backlight/brightness: not found Traceback (most recent call last): File "/home/mintbook/Downloads/comice-control-center/./comice-control-center", line 75, in do_activate display_level_box = DisplayLevelBox() File "/home/mintbook/Downloads/comice-control-center/comicecontrolcenter/widgets/display_level.py", line 17, in init brightness = BrightnessInformation() File "/home/mintbook/Downloads/comice-control-center/comicecontrolcenter/functions/brightness_device.py", line 36, in init self.brightness = int((int(result3) * 100) / self.max_brightness) ValueError: invalid literal for int() with base 10: ''

I noticed someone else had a similar issue with Bluetooth. My error seem to be with brightness? not really sure what I would need to change. Thanks.
