Going to try this app for some more lag reduction on my nook color CM 10.1. Just came across this app last week and hesitated on applying it to my nook color, kind of looks like a defragger app in-disguise, and as we know, we should NEVER run a defrag app on a SDD (Solid-state drive) or your flash memory on your internal memory, or eMMC.

Here is the source code for this app here on sourceforge.net. http://sourceforge.n...ects/fstrim/  .

This app is just as controversial as the "enropgy seeder" app, using dark magic programming techniques I covered in my other thread *follow along with me trying to learn how to code* here.

~~~~~~~~~~~~~~~~~~~~~

Here is the link up in XDA forums for this app. http://forum.xda-dev...d.php?t=2116225

And this link here is for the app on the playstore. It is a free app. https://play.google....ey.lagfix&hl=en

~~~~~~~~~~~~~~~~~~~~~

So add your comments and opinions on this app guys. And don't be shy.   I will give this app a try here in a day or two and report back on whether it works on the nook color on Cyanogenmod 10.1 nightlies and our recent RC (release candidiate.) here in this thread.


~~~~~~~~~~~~~~~~~~~~~~

Some are also reporting this app is also more snake-oil and/or a placebo effect so you will have to be the ultimate judge on whether this app does indeed reduce lag. Here is a page on <fstrimming> on-line here to research over. http://blog.neutrino...vm-and-dmcrypt/

I found another solution for us using linux to automount the nook color with cyanogenmod 10, for those using the KDE desktop environment or Plasma desktop. Been looking over this distro also.

This solution uses the "Android MTP Support" in KDE called "kio-mtp". Before you had to compile this tool with dependences called "cmake" and "gcc" along with a few other tools. This build is now available to you on the "apt-get" and I will post the code below for an easier solution for those using the KDE desktop environment along with the installed Dolphin file manager.

Open up your Konsole or bash terminal in KDE.

~~~~~~~~~~~~~~~~~~~~~~~

First, add the PPA repository to your linux build using the KDE desktop environment so this tool will stay updated.

sudo apt-add-repository ppa:philschmidt/ppa-kio-mtp-daily

Then update and install the repository for this tool.

sudo apt-get update

sudo apt-get install kio-mtp

Now plug in your Android device or nook color using cyanogenmod 10 or 10.1+ and you will be able to manage it from within the "Dolphin" file manager without any errors. Tested and working for me using Kubuntu on "Virtualbox" and 'Vmware workstation 9.0.1" hypervisors on a Windows 7 host for my nook color.

The developers have announced that CM 10.1 is now in alpha testing for the nook color. This update to Android 4.1 Jellybean will bring updates and other features to bring Cyanogenmod (CM) 10 up to Android 4.2 for us. !!  So check over this announcement up in the XDA nook color forums up at this thread link here and give your thanks and thoughts. http://forum.xda-dev...d.php?t=2132299

This update to Android 4.1 will bring some stability patches and other minor fixes to the code for us using CM 10. These fixes are mostly under the hood and in the kernels to help improve the code. So give your support and look it over devs and testers.

Here is the download for the new CM 10.1 alpha for the nook color. Remember this is a build still in alpha so you can expect some bugs. http://techerrata.co...-fullofbugs.zip

The .gapps file for your new CM 10.1 to access the Google 'playstore" is found here. http://techerrata.co...1212-signed.zip

I found a fix for us using the nook color on linux builds. Tested it out on my machine using both Linux Mint 14.1 and Ubuntu 12.10 using CM(cyanogenmod) 10 for an auto mount solution. This is a faster transfer rate for moving files on between the nook color using CM 10 under linux. Someone back-ported a feature from Ubuntu 13.04 "Raring Ringtail." Since that linux build is still in beta, some might not be using it yet. The tool is called a "GVFS-with MTP."  This tool will AUTOMOUNT your nook color in linux. The source for this information is here. http://www.webupd8.o...support-in.html

First we will have to add the PPA (Personal Package Archive) through the terminal in these linux builds.

1. To add the Gvfs (and libmtp) PPA created by the Gvfs MTP backend developer in Ubuntu 12.04 or 12.10, use the following commands:

sudo add-apt-repository ppa:langdalepl/gvfs-mtp

sudo apt-get update

2. Then, launch Software Updater (previously known as Update Manager) and install the available updates.


3. Once everything has been updated successfully, RESTART your computer, unlock yournook color, connect it via USB and it should show up in your file manager. (Tested with Nautilus 3.6+).

If you don't unlock your Android 4.0+ device, it may show up as empty in the file manager, at least that was the case for me.

~~~~~~~~~~~~~~~~~~~~~```

Connect your nook color in linux to now see the nook color icon pop up on the desktop!! You can now move and transfer files that way instead of using the android ADB through the terminal. This is a faster solution on transferring files through your nook color to Ubuntu 12.10 or other linux builds.

~~~~~~~~~~~~~~~~

Ubuntu users: Make sure you have the gnome "tweak tool" installed and have the options of "showing mounted volumes on the desktop" enabled or "on" to see the nook color mounted icon on the desktop.

I just tried this new .apk on the nook color yesterday, and after checking it over with my "cool tool" app which monitors CPU use-age on web sites and the RAM memory settings, I got to say the author of this fine app is being modest in his posts at best. Noticed a quite a bit of lag reduction through the GUI of CM 10 for the nook color on opening up options in there.

This is a simple app to set up. Just a button to click on to reduce lag along with a few other modifications clicks for more I/O scheduler settings to boot the code that was not debugged and optimized fully from Google for Android Jellybean 4.1.

Make sure you give Superuser privileges to this app on install.

The little annoying split seconds of lag are now gone on my CM 10 build on applying this app. For more information on this app look here at his thread up in the XDA forums. Even he is somewhat over my head on what he is discussing, he is a true *nix wizard.  http://forum.xda-dev...d.php?t=1987032

~~~~~~~~~~~~~~

Its not a placebo effect, you notice right away. Did a test on my other guide thread here in the forums, at this link here with the nook color where I was getting some slight lag with all of the youtube and pictures I had in the thread.  http://forum.xda-dev...d.php?t=1987032

My nook color had some slight lag through that link I had with CM 10 before Entropy Seeder. Not any more with this app. So check it over for yourself and see if its just a "placebo" effect. I am convinced its not. Unless my nook color just decided not to lag on that one link I gave with this app just being installed.

For a download link for this apk you can install right away, check this link here, he also has this app on the 'playstore' for you to download at a small price for you to support him if it works well for you. http://dl.xda-develo...eeder-2.0.0.apk


Here is the bug thread for this issue on android, which CM 10 is a custom ROM of. https://code.google....ail?id=42265#c8

~~~~~~~~~~~~~~~~~~~~

Here is my mods and tweaks for getting the most out of CM 10 on the nook color.
