Kunal Bhat ([email protected]) changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[email protected] --- Comment #9 from Kunal Bhat ([email protected]) --- (In reply to Flo Bock from comment #8) > With recent systemd changes, the 16 bit values in actual_brightness break > saving and restoring the backlight values using AMDGPU. According to a > closed issue on Github, Lennart Poettering sees this as a kernel issue[1]. > Is there any good reason for actual_brightness to be 16bit, whereas both > max_brightness and brightness are 8bit? > > [1]: https://github.com/systemd/systemd/issues/16600 I believe it's there to provide a higher range of precision for the backlight. Not sure why they never extended the range for max_brightness. The systemd devs are adamant that this is a driver issue, and aren't ready to implement a work around for it. I believe this is the open issue with the discussions right now: https://github.com/systemd/systemd/issues/16630 -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list [email protected] https://lists.freedesktop.org/mailman/listinfo/dri-devel
