The steps outlined in the official documentation are working fine - I have set up the two monitors, and both are usable in many ways. But I can not find a way to use software to adjust the brightness of them.
I had another computer which was a laptop, and it worked to use f.lux on the external monitor but not on the integrated monitor, under Trusty 14.04, so I would like it to work on this computer too, with the two integrated monitors. I am linking another thread, where I had a bug report that I could not figure out how to edit, that I changed into a Question, so I have three IDs for this problem now. The question version seems somewhat useful. I marked the bug version of that one invalid. I think it may be best if I merge all the information into this report. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1545266 Title: screen brightness slider has no effect To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-docs/+bug/1545266/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
