iPaq demo sources?
From: Nils Faerber ####@####.#### Date: 3 Nov 2000 17:59:14 -0000 Message-Id: <00110319031305.00962@twincan> Hello! First of all let me start by telling how amazed I am by the just released microwindows (nano-x) demo for the iPaq! It runs much better than anything I had already running (which will be because the demo uses the latest nano-x version which was not yet available?). I still think that nano-x is the way to go for any current Linux PDA though there is still much work to do (double buffering would be SO nice ;) I hope that I can contribute to it some day (a flnx mp3 player is already in the works ;) Though I wonder where I can find some of the sources that are used in the demo especially the nxscrtop. I would very like to change some things in it (remove the seconds from the clock, switch off display completely when tapping on the backlight button, add automatic display blanker (yeah, that was me some weeks ago)). I just browsed the sources of microwindows pre5 and could not find any hint for it. Anyway, great work!

From: Jordan Crouse ####@####.#### Date: 3 Nov 2000 18:52:48 -0000 Message-Id: <3A0309C6.B836CDC5@censoft.com> Nils - I was under the impression that the power management in kernel test17 was virtually nonexistent (except of course, for battery life monitoring). I am unaware of any code that will actually turn off the screen. So unless I am way off base, a screen blanker wouldn't be very useful at this point, since the power would still be running the screen, even if the screen is blank. Do you know of any code that will turn off the power to the screen? If so, I would love to see it, because that would make life really cool. Until then, I think that your best bet would be to just turn off the backlight, so you could save as much power as possible, but still see something on the screen. Let me know if I am barking up the wrong tree. Happy hacking!

If so, I would love to see it, because that You can turn the display off completely and thus save power: ioctl(fd,FBIOBLANK,VESA_POWERDOWN) does the trick. > would make life really cool.

After more inactivity the display should shut off completely and then after another timeout the whole thing should go to sleep. > Let me know if I am barking up the wrong tree. Hmm ... almost seems so ;) > Happy hacking! Also! I have attached a complete blanker source. Now that you have my source would you share nxscrtop's source with me? > Jordan CU nils faerber -- kernel concepts Engel & Faerber GbR Tel: +49-271-771091-12 Dreisbachstr. 24 Fax: +49-271-771091-19 D-57250 Netphen D1 : +49-170-2729106 -- [Content type text/x-c not shown.
