Other thinkpads that use Intel integrated graphics are able to control LCD brightness via the KMS module after r270516 in HEAD (merged to stable/10 in 279961 which is after 10.1). However, those do not use acpi_ibm, but do work with acpi_video. On my x220 the following things appear to work in acpi_ibm: 'mute' sysctl (can write to it to mute, and the mute button change its state, also writing to it changes the mute light) 'thinklight' sysctl 'fan_speed' sysctl Thanks for suggestion about acpi_video ... but it makes the whole case wven more 'fun' ;) After loading acpi_video module, the hardware buttons for brightness does not work anymore and after kldunload acpi_video system reboots instantly. Regards, vermaden On my X240 with 11-CURRENT (drm-i915-update-38 actually), acpi_ibm is useless as well.
The sound volume keys are passed to Xorg as XF86Audio{Lower,Raise}Volume, but the brightness keys aren't. The lower brightness key just resets the brightness to maximum, the raise brightness key does nothing. I think these keys should be passed to Xorg as XF86MonBrightness{Down,Up}!
acpi_video brightness adjustment (sysctl hw.acpi.video.lcd0.brightness) works though. graphics/intel-backlight works too.
batch change: For bugs that match the following - Status Is In progress AND - Untouched since 2018-01-01. AND - Affects Base System OR Documentation DO: Reset to open status. Note: I did a quick pass but if you are getting this email it might be worthwhile to double check to see if this bug ought to be closed. My T520 had the same issue and it was fixed at least two years ago. Works fine for me. Would be nice to see come confirmation from a W530 owner, but they are likely pretty rare by now as all are at least 6 years old. Then again, my T520 works fine, if a bit memory limited, after 7 years. It was reported on 2013. Lots have changed since then. Closing. |
