Description Thomas Backlund 2013-09-26 21:29:21 CEST

Quoting http://lm-sensors.org/


September 5th, 2013:
Hardware breakage reported Over the past few months, we had several reports of sensors-detect causing serious trouble on recent hardware (most notably laptops.) We still don't know what exactly is happening, and while it might be reversible, we don't know how, so in practice this is equivalent to the hardware itself being broken. The symptoms are that the display starts misbehaving ( wrong resolution or  wrong gamma factor.) We have mitigated the risk by changing the default behavior of sensors-detect to no longer touch EDID EEPROMs and then to no longer probe graphics adapters at all unless the user asks for it. We urge maintainers to backport changesets r6040 and r6084 to all Linux distributions which are still shipping lm-sensors 3.3.2 or older. Versions 3.3.3 and newer are not affected.


mga3 has 3.3.3 and cauldron has 3.3.4 so they are ok.

So I've pushed lm_sensors 3.3.3 from mga3 to mga2 updates_testing to resolve the issue there too

Reproducible:

Comment 2 Zoltan Balaton 2013-10-02 22:52:55 CEST

Tested on mga2 x86_64 by updating lm_sensors from Testing repo and verifying that sensord and sensors still provide measurements. Everything seems to be working after update but I have no access to hardware affected by the original problem and did not try to rerun sensors_detect.

CC: (none) => balaton

Comment 3 claire robinson 2013-10-03 15:47:44 CEST

Thankyou Zoltan!

Whiteboard: (none) => mga2-64-ok

Comment 4 claire robinson 2013-10-03 15:49:06 CEST

Testing mga2 32, ancient hardware though so not able (or wanting) to reproduce.

Comment 5 claire robinson 2013-10-03 16:02:39 CEST

Testing complete mga2 32. 

sensors-detect found no sensors but the scan had no ill effect.

Whiteboard: mga2-64-ok => mga2-64-ok mga2-32-ok
