No it's not official. I don't represent the RPF. It's a "paraphrase" of something I've seen Gordon write either here in this forum or as an answer to a question on the original display launch blog post. I expect he'll be along shortly to tell me I'm talking a load of nonsense or say I'm roughly rightmorphious6 wrote:is this the official response or we think it may not be available yet?
Would like to get this ASAP, as I plan to add a proximity sensor to turn on when I enter room and off after a certain time frame.
What is the expected lifetime of the backlight ?morphious6 wrote:There has to be some way to shut this down while not in use, or these screens won't last very long with the backlight on 24/7
I realize that this is going to be a request for "feature creep" (aka "creeping featurism"), but could this feature also permit the display to be dimmed on command?gsh wrote:I'm trying to write it now, but have picked up a cold and therefore am sat at home trying to do it remotely which isn't good!
Makes sense!You'll get it when it is ready.
Programmers tend to be optimistic about how long a project takes. If the programmer spends time talking about when he expects to be finished, that takes time away from getting it finished. I *think* the RPF has managed to escape the tendency of managers accepting what the programmer has said about schedule, then cutting that down to please the next management level up.Dataworm wrote:Makes sense!You'll get it when it is ready.
Of course we are patient. But it would be nice to get some feedback about the estimated time until it is finished/published. I don't think the coding will take that much time but depending on human resources, more important tasks and release cycles, it might take days, weeks or in worst case even months. So if someone should know something about expected times, I would be glad to hear them. And yeah I know that estimated times for programming can change a lot!

With my current build (not released yet) will do that... The thing I'm having trouble with right now is getting it to correctly blank the backlight when it goes to suspend, sometimes it works sometimes not...
The reason it didn't work is contained in the text you quoted.solar3000 wrote:that does not work.
'File not found'
/sys/class/backlight/: no files, just an empty folder
