the changelog of kp49 is present in the first post of its official thread...and for 720p read the first properly there is also a link to the guide to install only using N900...again read the first post carefully in 720p thread..installing using only N900 is mentioned after the first few lines..

renice 1 `cat /syspart/applications/standby/background/tasks`
does not work because there no dir after /syspart/ if using speedpatch (cgroup).
So for speedpatch code is

renice 1 `cat /dev/cgroup/cpu/applications/standby/background/tasks`

also testing
renice 1 `pgrep browserd`
renice 1 `pgrep image-viewer`
in cpu_sleep

and in cpu_normal

renice 0 `pgrep browserd`
renice 0 `pgrep image-viewer`

will report ASAP if this improves anything.

i was doing tests about it (with speedpatch)
already did that modify

but .... in my case i got less battery time on standby

tell me what happens with you

Recently I started to see a speedpatch error when xterm is loading and then it disappear when xterm has loaded, I have already tried rebooting alot of times already but the error still remains. I tried to remove speedpatch but the cgroup folder still remains even after a bunch of reboots. Whenever I try to delete the folder via filebox or xterm I get an error saying folder cannot be deleted. Is there another way to delete this folder.

@mrwormp

your problem is *not a problem*

speedpatch works well but looks like xterminal has cached a pvr when once speedpatch installed (looks like you launched xterminal when you installed speedpatch directly)

install speedpatch and

Code:

(as user)
rm .cache/launch/com.nokia.xterm.pvr

and your peoblem will be solved
xterminal will recache a new window

and about the unistallation issue
there is actually a problem in confile (inside the deb configs)
it considers /etc/speedpatch is from configs but it's not
to remove it you need to
apt-get purge speedpatch

or use the fuill removal-script from 1st post

then reboot and cgroup folder will not existed anymore

While waiting for batterypatch 720p update, because dsp profile stays permanently at 805 mhz while the screen is unlocked, I've copied dsp profile content over both underclock and overclock profiles limiting the min and max frequences with:

underclock -> Min Freq = 125 Max Freq = 250
overclock -> as dsp default profile

using this combination i'm sure that my N900 won't go forever at full speed even when it's locked

I had to complete flash my N900 for some hang on heavy load issue.
but my test was complete.

Code:

renice 1 `cat /dev/cgroup/cpu/applications/standby/background/tasks`

not needed because they are background task and cgroup manage them as they should.

in cpu_sleep i added

Code:

renice 1 `pgrep modest`
renice 1 `pgrep browserd`
renice 1 `pgrep image-viewer`

and in cpu_normal

Code:

renice 0 `pgrep modest`
renice 0 `pgrep browserd`
renice 0 `pgrep image-viewer`

and for both locked and unlocked the

Code:

ignore nice load = 1

IMPROVED my standby time.

these scripts dont have any problems. e.g black screen, conversation issue etc.

Im using kernel-power v49.
if you need my overclock and underclock profile just ask. I'll post them here.

hmm i see

can someone else test them before i put them in batterypatch ?

thank you carbonjha

and you can pm me your profiles or post them here
