FAQ
(übersetzt von hier)

F: Zieht doubletap2wake/sweep2wake sehr am Akku?
A: Ja, auf dem Nexus 5 leider schon. Wenn man die Aufweck-Funktionen aktiviert, kann man ein Timeout festlegen oder die Power Button-Toggles verwenden, um dt2w zu deaktivieren falls man das Handy für etwas länger nicht nutzt.

F: Die Minimum-Frequenz hängt bei 1267MHz fest...?
A: Nein, tut sie nicht. Wenn der Touchscreen des Handys berührt wird, ist es Absicht, dass die Frequenz hoch schießt und wird danach zurück auf 300 MHz gehen. Es gibt jedoch einige Apps, die die Frequenz tatsächlich bei 1267 MHz "einfrieren" lassen. Deshalb der Tipp des Devs: NIEMALS PER APPS AN DEN FREQUENZEN RUMSPIELEN!!! Am besten bei Installation des Kernels über den Aroma-Installer einstellen und dann so lassen.

F: Was ist der Unterschied zwischen dem Standard-Kernel und der Express-Version?
A: Installiert man die Standard-Version dieses Kernels, hat man direkt vor der Installation über den Aroma-Installer die Möglichkeit, verschiedene Einstellungen vorzunehmen und sie so anzupassen. Die Express-Version hat keinen Aroma-Installer und installiert den Kernel mit den normalen Standard-Einstellungen. Hinweis: Bei der allerersten Installation dieses Kernels ist es ratsam, die Standard-Version mit dem Aroma-Installer zu verwenden (also nicht express) und bei Updates dann die Express-Variante.

F: Welche App wird zur Kontrolle der Kernel-Einstellungen empfohlen?
A: Um die Einstellungen des Kernels zu ändern wird keine separate App benötigt, da alles direkt bei der Installation über den praktischen Aroma-Installer eingestellt wird. Wenn es jedoch unbedingt sein muss können altbekannte Apps wie Faux Clock, Franco Kernel Updater oder TricksterMod verwendet werden.

F: Sollte mpdecision deaktiviert werden?
A: Nein.

F: Ich habe einen sehr miesen Akkuverbrauch - was kann ich tun?
A: Das kann passieren, wenn sweep2wake oder doubletap2wake aktiviert sind. Falls nicht läuft mit dem Handy etwas nicht ganz richtig.

Spoiler: Konfiguration Info (englisch)

ElementalX Configuration File
Your choices in the Aroma installer are used to build a configuration file. The config file is located at /etc/elementalx.conf. You can edit this file to change kernel settings. Whatever is set in this file will take effect when the device is booted (unless other scripts or apps interfere!)

The settings can be changed by editing /etc/elementalx.conf and rebooting. Advanced users can apply settings on the fly by running /etc/init.d/99elementalx as root.

There is no need to edit /etc/init.d/99elementalx. All settings are configured in /etc/elementalx.conf.

If settings are not sticking, make sure the file permissions for /etc/init.d/99elementalx are set to execute. Every time the settings are applied, a log file is created at /data/local/tmp/elementalx-kernel.log. Problems can be diagnosed by looking at the log file.

Please check to see if any /etc/init.d scripts or apps (such as Kernel Tuner or Trickstermod) are interfering with your settings.

ElementalX Log File
Every boot, a log file is created at /data/local/tmp/elementalx-kernel.log. This file shows the date and time and all settings that have been applied. Use this to verify and troubleshoot configuration options.

Kernel Tuner/TricksterMod, etc
You don't need these apps because the ElementalX installer sets everything up automatically, but if you want to check or change settings, you can use these apps. Just be aware that some of them (e.g. Kernel Tuner) are set by default to apply settings on boot, which can interfere with the settings you chose in the ElementalX installer.

Overclocking
Overclocking (or underclocking) is optional. The installer lets you choose the maximum frequency. You can set the maximum frequency individually for each CPU core in the installer. Whatever frequencies you chose in the installer will be set at boot for each CPU. Not all devices can handle overclocking. I don't recommend overclocking, this device is fast enough. If you overclock, the CPU frequency will likely be throttled due to heat.

CPU voltages
The installer allows you to choose from several undervolting options. These automatically undervolt the lowest frequency (300MHz) where the CPU spends most of its time. The voltages for other frequencies are assigned based on the PVS bin of your phone. CPU voltages are fully customisable with apps such Kernel Tuner or Trickster Mod, but I recommend leaving these other voltages as-is unless you are prepared to do a lot of testing. Be careful, lowering voltages can cause instability. Generally, having reboots while the phone is asleep or other weird problems is a sign that your minimum voltage is too low.


GPU Governor
The default GPU govenror is ondemand. It works well and is recommended for best balance between performance and batter life. The simple governor is also available, but ramps up the GPU frequency much quicker than ondemand, so may impact battery life. The governor can be set in /etc/elementalx.conf

fsync
fsync can be disabled if you're looking for the last ounce of performance. I recommend leaving it enabled unless you are sure your device is 100% stable.

Max screen off frequency
The default max screen off frequency is 1190MHz, which is a good balance between limiting the voltage/frequency and the time required to complete tasks while the screen is off. This can be changed manually at /sys/devices/system/cpu/cpu0/cpufreq/screen_off_max_freq

Installing a new ROM
If you install a new ROM, it will probably replace this with the stock kernel and will definitely overwrite /etc/init.d/99elementalx and /etc/elementalx.conf so you will lose your settings and certain features. So always reinstall the kernel after installing a ROM.

NTFS and exFAT support
This is for anyone who wants to use OTG to connect a USB stick or portable harddrive formatted with Microsoft's NTFS or exFAT filesystems. You will need Stickmount or a similar app,

Sweep2wake
Sweep2wake (S2W) allows you to wake or sleep your device by swiping your finger across the bottom of the screen where the back, home, recent buttons are. Swiping from right to left will put it to sleep (sweep2sleep) and swiping from left to right will wake it up (sweep2wake). You can edit /etc/elementalx.conf to change the setting on boot.

/sys/android_touch/sweep2wake

0= disabled
1= sweep2wake/sweep2sleep

Doubletap2wake
DoubleTap2Wake (DT2W) allows you to wake the device by double tapping anywhere on the screen. You can edit /etc/elementalx.conf to change the setting on boot.

/sys/android_touch/doubletap2wake

0 = disabled
1 = enabled

Color preset
There are two color presets: stock and slightly cooler. You can edit /etc/elementalx.conf to change the setting on boot.

/sys/module/mdss_dsi/parameters/color_preset

0 = stock color
1 = slightly cooler color

Backlight dimmer
Backlight dimmer allows you to adjust the LCD screen brightness lower than is possible with stock. Be careful, you can lower the brightness so much you can barely see it. You can edit /etc/elementalx.conf to change the setting on boot.

/sys/module/lm3630_bl/parameters/backlight_dimmer

0 = disabled
1 = enabled

USB fastcharge
USB fastcharge is optional. This will allow you to charge at a faster rate when connected to a USB port. The normal limit for USB ports is 500mV, this increases it to 900mV. Be sure that the computer/laptop/whatever you are plugged into can handle it. Some will automatically cap it at 500mV. Please note that this does not force AC charge mode like previous implementations of force fastcharge. Your battery setting will still say USB mode. You can edit /etc/elementalx.conf to change the setting on boot
