From upstream ticket 2392:
We had a report of sensors-detect breaking the display of a Lenovo g50-80 laptop: http://lists.lm-sensors.org/pipermail/lm-sensors/2015-May/043905.html There is an I2C chip at address 0x4f on the DPDDC-A bus which reacts weirdly to SMBus Read Byte transactions. Most likely it interprets them as writes, treating the register address as a value. Fixed by: sensors-detect: Detect graphics card in all cases http://www.lm-sensors.org/changeset/6282 and: sensors-detect: Skip addresses 0x37 and 0x4f on DDC channels http://www.lm-sensors.org/changeset/6283 This is somewhat similar to bug #838619, but requires an additional fix. -- You are receiving this mail because: You are on the CC list for the bug.
