I was wondering if there was a way to modify the s78 enable touchscreen script so it will work on my phone...or if there is a way to add the directories it needs to work to the SYS directory...
the script is:
echo 7035 > /sys/class/touch/switch/set_touchscreen;
echo 8002 > /sys/class/touch/switch/set_touchscreen;
echo 11000 > /sys/class/touch/switch/set_touchscreen;
echo 13060 > /sys/class/touch/switch/set_touchscreen;
echo 14005 > /sys/class/touch/switch/set_touchscreen;
and is supposed to alter the touch screen sensitivity...I noticed it is included in a ROM i was using by the dev...but when i try to run it it errors out because it cannot create the directories as needed...
I have a rooted epic 4g touch
please let me know if any more information or details are needed
thanks in advance

I have a question about adding different governors to the init.d scripts?
Is it possible to just add governors to the init.d script even though it is not in the kernel itself?
For example adding this:
echo "800000" > /sys/devices/system/cpu/cpufreq/smartass/awake_ideal_freq;
echo "200000" > /sys/devices/system/cpu/cpufreq/smartass/sleep_ideal_freq;
echo "800000" > /sys/devices/system/cpu/cpufreq/smartass/sleep_wakeup_freq
echo "75" > /sys/devices/system/cpu/cpufreq/smartass/max_cpu_load;
echo "45" > /sys/devices/system/cpu/cpufreq/smartass/min_cpu_load;
echo "0" > /sys/devices/system/cpu/cpufreq/smartass/ramp_up_step;
echo "0" > /sys/devices/system/cpu/cpufreq/smartass/ramp_down_step;
echo "24000" > /sys/devices/system/cpu/cpufreq/smartass/up_rate_us
echo "99000" > /sys/devices/system/cpu/cpufreq/smartass/down_rate_us
Even though the kernel doe's not have smartass folder?
Will this run properly?
Hi There!!
Im Using [ROM][Mini/Mini Pro/Active/LwW]MiniCMSandwich Lite AOSP by Kamarush and I am really good with this now.
Problem is I dont want to use such too as SetXperia to Manage CPU, Voltage and I/O Scheduler.
So I am looking for some Init.d Scripts managing this. Has anyone out there got some helpful hints?!
Thx and Have a nice Day!

define frequencies of cpu, i/o and governor of your choice
Thank you man!!!!
So. What about the CPU Voltage - is there any way to undervolt by init.d - and is there any sense in it for getting more out of battery???!
Also I wonder how to manage swap file by init.d and what will I get out of it.
Sorry for the bad english!

From this table you can make your settings UNDERVOLT/overclock
note the frequency table used in the kernel
I do not use swap
Code:

Is there a good way to read out system stats and check if everything is working fine?!!
An app???
Hi again!
So... new Try, new Problem.
I've set up the following:
In dir "/system/etc/init.d" ive put three files.
- 1CpuControl
- IOSchedulers
- 97tweaks (this one was there by default in kamarush's ROM)
1CpuControl:
#!/system/bin/sh
echo "smartassV2" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
echo "806400" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
echo "245760" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq

echo "2016000 1400" > /sys/devices/system/cpu/cpu0/cpufreq/vdd_levels
2IOSchedulers
#!/system/bin/sh
echo "sio" > /sys/block/mmcblk0/queue/scheduler
In 97tweaks i just deleted the governer setting
Then rebooted and used the setxperia app to read out the System Information.
The Voltagetable is set correctly and the scaling_max_freq and scaling_min_freq are set correctly.
But the Governer still is set to OnDemand and I/O-Scheduler is still set to deadline
Anyone knows what went wrong?!
The Scripts are exactly set as posted above... Maybe the xperia tool is not able to read out the settings correctly???
Bye!!

Probably kernel doesn't have those governors and schedulers then, if these are not set.
Which kernel you have, the first or 2nd one?
Hi and thx 4 answering!
The 2nd one => "boot_mango_v2_lite.img"
With SetXperia App i can set "sio" and "smartassV2" successfully- so I think it must be possible... btw: do u know another app to read out the system stats???
What kernel are you using?
Bye
Nofrills Cpu control can also see that info.
Sent from my Xperia Live using xda premium.
Thank you!
NoFrills set up everything without any probs
really wanna know what the hell is wrong with my scripts.
Nah, but thank you anyway man!

check the script path using root explorer and see if it is compatible
spaces at the beginning and end of the script may cause errors
use notepad + + for editing
Ok.
Since there are no errors in the script itself it must be a lack of compatiblity
I've just copy&pasted them from the web and edited all spaces on phone with total commander. Maybe there is some error. But I kept thinking some string is not correct, because the voltage and min/max-freq were ok.
Thanks for help!

I search in forum and write script

When I put it in init.d folder, set permissions, it not working! When I paste text in terminal emulator, all works.
What I do wrong? Searching forum and reading another threads not help!

If I can find solution, I will not ask! Here is many posted how to do, but I can't find, why it not working for me!
Solved!
In notepad++ rewrite all spaces, all works now!
emm, may i know, i wrote a script file
#!/system/bin/sh
echo '1024000' > /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq
echo '1024000' > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
and saved it as ScalingCPU, then copy it to init.d folder. then, i set the permission: ticked all 9 columns.
is that so?
How do I edit that script's values to increase responsiveness?
They are like this:
#!/system/bin/sh
chmod -R 777 /sys/class/touch/switch/set_touchscreen;
echo 7035 > /sys/class/touch/switch/set_touchscreen;
echo 8002 > /sys/class/touch/switch/set_touchscreen;
echo 11000 > /sys/class/touch/switch/set_touchscreen;
echo 13060 > /sys/class/touch/switch/set_touchscreen;
echo 14005 > /sys/class/touch/switch/set_touchscreen;
chmod -R 444 /sys/class/touch/switch/set_touchscreen;
I am quite sure this is the correct file to edit!!
Please help!!

You will definitely see a boost in performance when running the following script.
For this to work, either run this code at boot with an app like ROM Toolbox.
Or run the attached file at boot with an app like Script Manager.
Thank you to PureMotive for the battery saving kernel tweaks to make compatible and tweak for this phone. and this thread by him
