Screen dimming XO1 vs XO 1.5
Folks: On the XO 1 with the osxx builds and 870, with no power setting options turned on, the screen still dims after a period of inactivity. The unit is active, but just the screen has dimmed off. Tapping a key or the trackpad brings the screen back on, and everything else including wifi is still active. This is a really neat 'feature', as it mitigates some issues with sleep/resume functions on the XO, while still saving an appreciable amount of battery life. However, on the XO 1.5, when, as well, both items in power settings are unchecked, the screen never dims. As such, walking away from the machine for 20 minutes or so is a pretty significant battery usage hit. Any chance at getting the 1.5 to behave like the 1.0? Even if this by design because the power settings behave better on the 1.5, IMO auto dim of the screen regardless of settings would be nice.

Are you talking about a screen dim where the screen remains on and readable but with less backlight intensity, or where the screen turns off and goes completely black?

Re: Screen dimming XO1 vs XO 1.5
Sorry, soon I will learn to use terminology correctly. In this case, by dim I meant instant off. :-) If I just walk away from an XO1 leaving it up, let's say, on the favourites wheel, after about 15 mins the screen backlight goes off, not dark, not dim, it goes completely off. This is with no power saving settings checked on. I dont think it's officially sleeping, or idle, since the 'activity' lights are still flashing, and the unit appears to still be on the WIFI lan. Tapping on a key brings the screen back on, and it would appear nothing else is 'resuming', because the rest of the box responds instantly, and to me still seems to have continued as active. As, I said, this to me is a 'desired' behaviour. This is on os23 and 870 on the XO1. With no power saving setting checked on the XO 1.5 walking away for, o, let's say, 24 hours, upon return, the screen is still on at full brightness. I'm also now testing simultaneously with 860 on an XO-1 to see if this screen-off is something 'new'. 20 minutes have already passed with no 'screen off' occurring, but stay tuned. I'm going to leave it on, and go out and cut the grass. I'll then also simultaneously try the same 4 scenarios in gnome upon return as well. (XO 1.0/860, XO 1.0/870, XO 1.0/os23, XO1.5/870) Cheers, KG On Sun, Jun 26, 2011 at 10:03 AM, Daniel Drake d...@laptop.org wrote: On 26 June 2011 14:55, Kevin Gordon kgordon...@gmail.com wrote: Folks: On the XO 1 with the osxx builds and 870, with no power setting options turned on, the screen still dims after a period of inactivity.

In this case, by dim I meant instant off. :-) Yep, this is a known issue - but one that we treat only with low priority. Auto screen poweroff on inactivity has been implemented on XO-1 but not on XO-1.5. The XO-1 implementation is a bit questionable, that's why it is not a trivial task to include it for XO-1.5. In future this may get easier, when we get our OLPC-specific display controller driver into the kernel, and when we eventually move our graphics driver into the kernel (KMS). So, I wouldn't worry about digging into this.

Auto screen poweroff on inactivity has been implemented on XO-1 but not on XO-1.5. given you referred to #9710, i'm assuming you think kevin is seeing DPMS. did we reenable DPMS on XO-1? i hadn't realized that. i've recommended keeping it off for some time, because it fights with powerd, but maybe you've fixed that. The XO-1 implementation is a bit questionable, that's why it is not a trivial task to include it for XO-1.5. equivalent functionality would be trivial, with a new checkbox to reconfigure powerd to allow dimming/blanking the screen but prevent sleeping. this would work on both platforms. paul In future this may get easier, when we get our OLPC-specific display controller driver into the kernel, and when we eventually move our graphics driver into the kernel (KMS).
