lightum crashed on startup #45

Closed WhyNotHugo closed 9 years ago

WhyNotHugo commented 9 years ago

On a MacBook Air 2013, running ArchLinux-amd64.

$ uname -a
Linux athena.barrera.io 3.19.0-1-ARCH #1 SMP PREEMPT Mon Feb 9 07:08:20 CET 2015 x86_64 GNU/Linux

kbdlight and xbacklight work fine on this system, so it would seem that all the modules to handle keyboard backlighting and screen brightness are in place.

The latter seems to look for ConsoleKit, but, AFAIK, it's been deprected since circa 2012.

Are you using the most recent version in the trunk?

WhyNotHugo commented 9 years ago

I was using the 2.3.1 release. Latest from git does work, however, the backlighting behaviour is inconsistent. With plenty of light, sometimes it's set to maximum, sometimes it's turned off. And the same happens when covering the webcam with my finger.

Shall I open a new issue for this?

esoleyman commented 9 years ago

Apply the patches from PR https://github.com/poliva/lightum/pull/44 which should solve these problems. Let me know and I'll add them to my branch.

WhyNotHugo commented 9 years ago

44 does not affect the problem in any way. It's something separate from this though, so I'll open a separete issue.
