Re: [Announce] EBD - Enhanced Backlight Daemon

Sorry guys... I will continue working on this as soon as I get back from my trip!

And if anyone wants the code in the meantime let me know!

Re: Massive interactivity improvement under high I/O load!

Sure, try:

dd if=/dev/zero of=/media/mmc1/testfile bs=1024k count=512

That will create a 512mb file on your SD card as fast as it can write. While it does that, try using the phone other tasks.

Re: Massive interactivity improvement under high I/O load!

You'll only notice a difference under intense I/O. Try writing a 2gb file to your SD card with the standard configuration... it'll tend to lock the device up. Then try it with these settings.

Re: Massive interactivity improvement under high I/O load!

I just put my settings near the end of /etc/event.d/rcS-late.

I'll be releasing a debian package soon as well.

Re: [Announce] EBD - Enhanced Backlight Daemon

Not yet... just a daemon for now (no configuration). But there will be. Updates to follow. :)



I'd be honored if they'd include it... but it still needs a lot of work before I'd even consider...

Re: [Announce] EBD - Enhanced Backlight Daemon

There will be, ya. I'm on a business trip at the moment but as soon as I get home I plan to implement a nice handy status menu widget for controlling its behavior.

Regarding keyboard backlight......

Re: [Announce] EBD - Enhanced Backlight Daemon

I'm not 100% sure, but try disabling "power save mode" under Settings->Display, and see if that helps.



Can you paste the result of the dpkg -i line?

I think I can make that work. It was my original intention but turned out to be tricky because a lot of processes adjust the brightness level on various events.

At worst, I'll implement an applet...

Re: lightsense.pl: Auto-adjust backlight based on ambient light

Hey everyone,

I rewrote lightsense.pl as a proper daemon in C, and built a package for it. Details here:

Re: Proper vsync and reduction of tearing

Heh... I just noticed that. Looks like the SGX driver is closed source. How annoying.

I haven't checked in portrait mode but I will take a look.

Re: Proper vsync and reduction of tearing

I'm not positive, but I think it's a memory bandwidth limitation for the mostpart. Between the video refresh (60hz 800x480x24bpp = ~69mb/sec) and the panning activity, I think the device is just...

Re: Proper vsync and reduction of tearing

Well, the thing is most animations on the phone don't even hit 30fps to begin with (just can't render fast enough)... so the LCD refreshes are just wasted anyway.

I would guess desktop panning is...

Re: Proper vsync and reduction of tearing

Well, I tried reducing the pixel clock from 24mhz to 12mhz, hoping that would halve the refresh rate.

Unfortunately it just reboots as soon as Xorg loads.. not sure why yet.
