Description Bill Nottingham 2005-11-16 14:55:25 EST
Description of problem: SSIA. I've certainly never configured it otherwise, and it seems somewhat odd - AC should default to highest brightness. Version-Release number of selected component (if applicable): gnome-power-manager-0.2.8-1 There are other issues with this interface as it's implemented: - it's done as a gradual fade - the BIOS *already* handles this on my laptop, so you have two different entities changing it The combination of this means that when you unplug the AC, you get: - immediate shift downwards about 50% - a half second later, a fade even more Not sure how you'd fix it, but it looks odd.
Comment 1 Richard Hughes 2005-11-16 19:11:08 EST
Have you tried 0.3.0? The spec file was improved in early in 0.3.0 development to actually install the schema (rather than install it, and then immediatly uninstall it...) -- that should fix the default values. About the gradual fade -- what laptop make and model do you have (IBM thinkpad?) because I can blacklist these based on the smbios properties -- that's easy to do.
Comment 2 Bill Nottingham 2005-11-17 12:03:55 EST
0.3.0 hasn't been packaged up yet. Yes, this is a thinkpad. I'm assuming you're using /proc/acpi/ibm/brightness. Looking at that file, I see it supports: $ cat brightness level: 7 commands: up, down commands: level <level> (<level> is 0-7) The fade would imply that you're using up/down instead of just 'level X' - is that the case?
Comment 3 Richard Hughes 2005-11-17 12:23:10 EST
No, I'm actually fading up and down by setting the level to a new value after I think 150ms steps. This makes non-fading laptops fade quite nicely, and it's much better than a suddern brightness change. I can blacklist thinkpads from the gradual change algorithm, so worry not.

Created attachment 121202 [details] Patch against CVS This should fix the double dim problem -- I'm pretty sure it should patch against 0.2.8.1 as I don't think the source has changed. Please could you test, and if okay I'll commit into HEAD.
Comment 5 Bill Nottingham 2005-11-17 16:10:42 EST
Seems to work for me. Closing as UPSTREAM, we'll get it then.
