Hi,

I just switched to Linux Mint 18.3 with the kernel 4.13.0-41-generic. Running monitor-sensor, I saw:

$ monitor-sensor
** Message: Light changed: 3.892000 (lux)
** Message: Light changed: 4.022000 (lux)
** Message: Light changed: 3.373000 (lux)
** Message: Light changed: 2.465000 (lux)
** Message: Light changed: 2.335000 (lux)

Note that the lines:

Waiting for iio-sensor-proxy to appear
+++ iio-sensor-proxy appeared
=== Has accelerometer ...

didn't even appear!

Just in case this information is useful, I am using Thinkpad X1 Yoga, and monitor-sensor used to work before when I had Ubuntu 17.10. Also:

So... how can I make monitor-sensor shows data from accelerometer properly? Thanks!

hadess commented 6 years ago

I don't know, but if you don't run it as root, it's certainly not going to work.

sorawee commented 6 years ago

I did run it as root, and the result for monitor-sensor is the same.

hadess commented 6 years ago

I'd need the output of iio-sensor-proxy itself, but run as root, there's tons of permission errors in your logs.

sorawee commented 6 years ago

Yeah, my original issue didn't run iio-sensor-proxy as root, but I realized that and fixed it 6 hours ago. It's weird that you still see the old one. Anyway, here's the the output when run as root.

What does a cat of /sys/devices/pci0000:00/0000:00:13.0/{33AECD58-B679-4E54-9BD9-A04D34F0C226}/001F:8086:22D8.0001/HID-SENSOR-200073.9.auto/iio:device3/in_scale give you?

Yeah, my original issue didn't run iio-sensor-proxy as root, but I realized that and fixed it 6 hours ago.

I read from the mail notifications. How am I to know that you fixed that problem in your comment if you don't say so?

I see. Sorry about that.

You seem to be using iio-sensor-proxy 2.2 or older. Could you please try with a newer version?

sorawee commented 6 years ago

Yup, resolved :) Thanks!
