RFE: disable auto brightness by default #89

Open pcfe opened 3 years ago

pcfe commented 3 years ago

automatic brightness just cost me a bit of time[1], a screen going dark at boot (seemingly off) and never seeming to wake up turned out actually being the auto-brightness setting in the GUI that led to a screen being at 1% brightness and me believing there was a hardware issue.

after a while and a hint from torbuntu I checked the brightness over ssh

[root@pinephone ~]# cat /sys/class/backlight/backlight/actual_brightness 
10
[root@pinephone ~]# cat /sys/class/backlight/backlight/brightness 
10
[root@pinephone ~]# cat /sys/class/backlight/backlight/max_brightness 
1000

Once I issued a echo 500 > /sys/class/backlight/backlight/brightness the screen lit up and I could navigate to Settings / Power to diable Automatic Brightness

Since other seem to have run into this, can you please consider switching auto-brightness off by default, at least until we find a way to not have the minimum value not go so low that the backlight switches off completele (off point seems to be around 100 on this device)

Has indeed been a pita for all of us. I believe this has been fixed in both latest stable release and the nightlies I build; so this bug should be closed
