Thanks for the report. Is it fixed in newer series of Ubuntu? If not we need to start by the devel one
> the readings from iio-poll-als are unstable, or could freeze on certain value isn't that the real issue? is that an hardware or firmware bug? could it be fixed rather than worked around in udev rules? -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to iio-sensor-proxy in Ubuntu. https://bugs.launchpad.net/bugs/1963628 Title: Force IIO_SENSOR_PROXY_TYPE to iio-buffer-als for some Dell models Status in iio-sensor-proxy package in Ubuntu: New Bug description: We are encountering issues, that when enabling some Dell laptops, the readings from iio-poll-als are unstable, or could freeze on certain value. On these systems they have ENV{IIO_SENSOR_PROXY_TYPE}="iio-poll-als iio-buffer-als", and removing iio-poll-als makes reading stable. This adds workaround to the affected Dell laptop models which may equip with ALS. [Impact] * Only models matching the same device BIOS IDs are affected. [Test Plan] * Pick devices which BIOS IDs are listed in the patch, and test whether it's ambient light sensors are working properly without unexpected brightness flickers. [Where problems could occur] * Machines matching the same BIOS ID, either having ALS built-in or not, but attached ambient light sensors externally (for example, ColorHug ALS) might experience failures.
