[Tutorial] ROMs & Sysctl.conf & other tweaks!

[macpro88]

Well what do you know. Enabling sysctl.conf in liberty settings does not actually alter the conf file. After enabling and rebooting, I checked /etc/sysctl.conf from terminal all the lines were commented out.

2048/40/15/12 were what was in there commented out though. I'm going to modify the file manually.

So what are you saying here? Do you have the Sysctl Config App by JRummy16 installed as well? Are you saying that when you use the app that the app is not actually altering the .conf files?

If you are using Liberty you do actually have to enable sysctl support first. This will/should remove the commented out parts. I don't know for certain because I modified my sysctl manually before it was an option but that's how I understood it to work.

O ok, I see. I do have Sysctl Support enabled, a long with the app installed.

How do I actually get to the file so I can see if the values really did change, and so I actually know how to change them manually.
I don't have much experience with using the command line or ADB or whatever it is lol.

I found jrummys init script that uncomments and executes the sysctl settings at boot time, but the prob is that the numbers in the conf file aren't what I entered in in the liberty settings at all.

Im unable to adjust my screens brightness now for some reason when I click on it it seems to stay on the advancced setting. Does anyone know why it could be doing this? I have juice defender and thought it might be causing it but I don't see any settings for that there?

Try stopping the service for juice defender and then changing the brightness.

Btw, here are the default unaltered vm settings of liberty. Vm. Swappiness of 60 surprises me. I don't think android uses swap.
