Ticket #2262 (closed defect: fixed)
backlight brightness of 11 unusable after blank/unblank
|Reported by:||lindi||Owned by:||openmoko-kernel|
|Blocking:||Estimated Completion (week):|
Steps to reproduce:
1) run Xorg
2) sudo sh -c 'echo 11 > /sys/class/backlight/gta02-bl/brightness'
3) xset s 10
4) sleep 10
5) xset s reset
If screen is readable after 2) then it is also readable after 5)
Screen is readable (although very dim) after 2) but completely blank after 5).
1) Setting backlight brithness to 12 or higher does not seem to cause this bug.
2) This bug also occurs with Xglamo
3) If you wonder why this is a problem: I was using FR in a car at night and wanted to use very dim display so that I don't disturb the driver. After the screensaver hit blanked the display I was forced to remove the battery to get the phone back to a usable state since using touchscreen blindly to increase backlight brightness was quite impossible and error-prone in my case.
