Committed on 16/06/2022 at 18:17. Pushed by ratijas into branch 'Plasma/5.25'. upower: Prevent integer overflow during new brightness computation Provably, if two integers can fit in 31 bits each, the result of their multiplication is expressible in 62 bits (let alone 63 available). So, this should be safe. And the division can't do much harm: the divisor is always at least 1, and worst case scenario — it would be so big that the overall results becomes zero. This code still assumes that the allowed brightness values can fit in 32 bits int, which is not totally unreasonable so far.

Does it work if > you click on a position in the track rather than dragging the handle? I’ve reverted the commits for some time now, but as far as I remember both the slider and the keys had the same effect. It was not only blocking at ~20 % but the brightness was also flickering between steps until it reached that level. So it would do something like 6%, 8%, 2%, 12%, 1%, 16%, 3%, 18% (not precisely these numbers but you get the idea). -- You are receiving this mail because: You are watching all bug changes.
