TIPS: Speed up Nook 7 performance - NOOK Tablet 7" Questions & Answers

So I've been playing around with my nook a lot and found a few ways to improve performance.
First off, enable dev options.
Under dev options, reduce Animations to .5x or OFF.
The second huge speed up I found was by reducing the resolution. To do this, you need to enable adb.
From an adb terminal, type:
adb shell wm size 500x854
adb shell wm density 133
adb reboot
This will change the default resolution on the Nook to 854x500 (I cannot tell a difference from 1024x600). Less pixels to render = faster! Games run faster too! This setting will persist through reboots, so to undo it:
adb shell wm size reset
adb shell wm density reset
adb reboot

Anyone have any further tips? I'd root it and put a bare bones ROM on it but apparently that's out too.

Lapdock resolution is off?

Strange situation. I got the lapdock a few days back from the sale and I'm running Darkside w/ Fruitcake 2.3.5 webtop. I plugged it in, everything works (although by god it boots slowly) except the desktop doesn't go to the edge of the screen. There's a black margin around the display that my mouse cannot reach. The displayed screen is smaller than the actual LCD screen.
I had tried fastboot wipe webtop and reinstalled fruitcake with no improvement. I had also tried webtopmod1 and the issue persists.
Any ideas?
maybe lcd density settings can/are messing with it? just throwing that out there.
I had the same issue on my hacked webtop. I resolved it by editing my /etc/X11/xorg.conf file.
Towards the bottom are "Screem sections". These define possible choices for screen layouts. In my file, the second of these Screen sections has an Identifier "Screen HDMI". In this, you can set the mode and virtual screen size. Set these both to 1366x768.
You obviously need root, and a way to edit the file. Once edited, reboot (clsing and opening the dock does not restart X).
Original:
Code:
Section "Screen"
Identifier "Screen HDMI"
Device "Tegra HDMI"
Monitor "HDMI"
Option "ARGBHWCursor" "false"
DefaultDepth 24
SubSection "Display"
Depth 24
# Uncomment to override the preferred resolution chosen by UseEDIDModes
Modes "1280x720"
ViewPort 0 0
# Defaults to the size of the chosen mode
Virtual 1366 1024
EndSubsection
Corrected:
Code:
Section "Screen"
Identifier "Screen HDMI"
Device "Tegra HDMI"
Monitor "HDMI"
Option "ARGBHWCursor" "false"
DefaultDepth 24
SubSection "Display"
Depth 24
# Uncomment to override the preferred resolution chosen by UseEDIDModes
# Modes "1280x720" Orig
Modes "1366x768"
ViewPort 0 0
# Defaults to the size of the chosen mode
# Virtual 1366 1024
Virtual 1366 768
EndSubsection
There might be better ways, but this worked for me.
NOTE: The virtual line need not exist at all per the comments
That was amazing! Thanks. It was way above my head and I'm glad someone can fix it.
Does this change work for the entertainment center also?
My webtop fits the lapdock screen just fine, but when I use the entertainment center, video is squished horizontally leaving 2 black vertical stripes on the sides.

Is there a way to edit the xorg.conf file right on the phone? Or do you adb copy it to a pc, edit it, and copy it back?

I am happy using vi in a terminal, but I assume that there are many text editor apps available.
I would caution you to be carefull though. Make a copy of the file first.
I have never used the entertainment center. so can not help you. If is is still 'droid though (and not a webtop flavor), this will not have an affect.
In my case when this happens, I fix it with a simple StartX command on LXTerminal.
However, ever since I went to Fruitcake 2.3.5 Webtop, the screen res change problem hasn't happened again.

Lapdock resolution is off??
Hi Everyone...I hopeI am not bothering anyone, even though I haven been reading lots of post with no luck about this issue... I am experiencing this same issue with the lapdock, it does not run at fullscreen, there are black bars all around.
I am running stock firmware 2.3.6 with webtop version WT-1.2.0-110_OLY-6 // Also the only modification I've done to the phone is that I root it...
One strange thing is that when switching to the entertaiment center it work at fullscreen! but not in webtop...
I already tried modifing the xorg file using Root Browser with same results, I've also use startx command from lxterminal but it keeps not showing at fullscreen.
I am still afraid of using webtop from fruitcakes as I am afraid to ruin the phone (n00b....reallly n00b)....so I would like to know if anyone has any other thoughts before testing with fruitcake?

[TIP] Adjusting DPI without root

How to adjust your DPI without root, I believe the current DPI is around 300 I could be wrong.
To adjust the DPI follow the steps below, THIS DOES NOT REQUIRE ROOT.
Open settings and scroll all the way down to About
Open Software Information
Tap the build number quickly a couple times till it says "You're now a developer"
Head back into the main settings page and open the new Developer Options
Enable USB debugging
Install ADB on your computer (there are plenty of tutorials out there if you don't know how)
Start ADB and check if you see your device by typing
Code:
adb devices
If you see your phone go ahead and type
Code:
adb shell wm density 250
Reboot your phone to apply the effects system wide.
250 is the DPI set which I think looks the best for me. Adjust how you like it
NOTE: IT WILL LOOK WEIRD AT FIRST, REBOOT YOUR PHONE!
This is a great method. Use it often. Couple more commands:
Code:
adb shell wm density reset (set to default)
adb shell wm size 1080x1920 (emulate whatever resolution)
adb shell wm size reset (set to default)
What Screen Resolution have you chosen?

I noticed in the pics from your review consisted of smaller icons. I am assuming you changed the DPI to 250. I would like to know if you have tinkered with your screen resolution as well. If yes can you show us some screenshots? Does that have any other benefits like battery performance and processing speed?

Yes, you're correct the dpi was changed. There's no performance gain I see. I do this so I can fit more on the screen at once within apps, while browsing etc... For me this is half the value of an HD device - you can shrink stuff down to fit 2x as much, but tiny text still remains comfortably legible.
This can also be done within terminal emulator. For me, not successful unless entering su.
nice way to adjust animations on your phone..its now fast without the animation by the way i need help i accidentally touch the Logger Buffer Sizes....its under settings..developer options...scroll down you will see. logger buffer sizes...now there are number to choose from..64k..256k...1m...4m...16m.... now would like to ask if what is your default value in your phone"? want to do default...whats the diffence it do when you change those settings 64...256...etc....tnx

Mine is 256k. That should be how much data is held in the logs.
thanks...got it...it just goes to default by itself when closing developer option......
This is pretty cool, is there an adb command to readout the density what ever it's currently set at?
I ended up at 390, it gives a nice 5x5 grid.
Thanx, work fine! A little notice: Asus Powermanagment end in force closed when you change the DPI. Went back to orig. 480 and it works, when you need it
And next big issue Swift key doenst work with changed DPI. When changed i saw only a few very!! big letters. Keyboard not useable.
Thanks OP!
The issue with swiftkey is well known and documented, just search Google for it (XDA says I don't have enough posts to post links yet). It looks like there's a fix, but it requires root. I switch to the Google keyboard and it works fine with modified DPI.
FYI, density setting of 460 is the lowest (stock is 480) that will keep the widget width taking up the whole screen for wide widgets. Makes everything a little sharper than stock, which was needed.
The hardware keys below the screen also stop working when the screen resolution is changed.

ZenMotion touch gestures config also crashes.
As for swiftkey, you could probably use xposed appsettings to adjust its dpi/dp settings.

Try a different DPI. 480 is extreme and some apps simply won't work properly at such a high setting.
After doing this, how to revert to the original one???

Snapchat text issue

So anytime I send a snap to someone or post on my story the text in the snap becomes very little to the left side. My dpi is standard for 1440 x 2560 and I don't know how to fix it. It's very annoying and hard to read. Someone please help. (Posted screenshot)
Did you adjust the DPI at all? Only thing I can think of. Thats super weird.

Yes but I've changed it back and set it to multiple dpi's. No luck. Even factory reset it. Nothing.
A factory reset should surely reset the dpi. Many apps have issues playing nice with an overridden dpi, specifically the functionalities that include resizing or cropping.
Try an "adb shell wm density reset && adb reboot" command for good measure

Lowest possible DPI for LeEco Pro3

What is the lowest possible DPI that we can go to for this phone?
I am coming from LG G3 using 520 DPI. I set the font size at 403 DPI for this phone and it seems to be quite large.
Set it to 360
Are there any options for lowering the dpi with the stock rom? I have been digging through the options but haven't seen anything yet.

texdroider seems to have no effect on fonts so i set it 350 from texdroider and then also used the adb shell to appropriate font size using this command
adb shell wm density 350 && adb reboot
it looks good now

White line on Samsung s8 display

Good evening, I changed phone in December and I have a Samsung s8 in perfect condition that I would like to pass to my wife, but turning it back on after time I noticed that on the left display stands an annoying white stripe at the edge of the vertical curve .. Right now. Done the various tests both normal and in safe mode and ascertained that the problem is hardware (having it checked by a Technician) my question is: is there a way to disable that line of pixel?
Being a peripheral area of the display is therefore not always used I would prefer at this point to be turned off because in the dark it really bothers .. Thanks to those who will help me ..
It looks like hardware damage.
I know.. That's why I wanted to try to modd the measurements of the display in such a way as to "turn off" the curves, or blacken them, and leave the rest of the display on... Always if it can be done
Check if Samsung allows you to run WindowManager. If it does, the change is permanent and remains after rebooting the phone.
The simplest description of how it works is here:
Android display offset/change position
Is it possible to offset the entire display content / change its position using adb shell? As i recently noticed it is possible to change the resolution . adb shell wm size <Res>. So , i was

Play with the settings and you will see how easy it is.
You can always restore the settings with the command
Code:
adb shell wm overscan reset

Small update... I managed to get the adb command prompt to work. I did some tests of shrinking the size of the display that succeeds very well, but that strip of pixels remains on ... Maybe I get the command wrong and I don't have to act on the Size?
In the adb shell just write wm then you will see the available options. You need the overscan option.
p.s.
You can only hide the white stripe with black adhesive tape.
