Hardware Acceleration

[Guest That-Guy]

Just a quick question about Hardware Acceleration, is it activated in the default rom shipped with the Orange San Francisco?

I am currently running this rom:

http://community.giffgaff.com/t5/Learn-gif...ade/td-p/133709

Does anyone know if it is enabled on this rom? or is there a way of checking?

Thanks in Advance :rolleyes:

[Guest Nick Rhodes]

It is not enabled by default.

That ROM is Sebastian404's de-orangenated ROM and does NOT have hardware acceleration enabled.

FYI you can check by open the zip and going into the system folder and opening the build.prop file (its a text based file).

I think the key is call debug.sf.hw={0 for off, 1 for on}.

Cheers, Nick.

[Guest That-Guy]

Thanks for the info.

Can I just load the zip change the item to "1" then re-flash the phone?

Is there a way anyway of enabling it on my phone without re-flashing?

Is there a downside to enabling hardware acceleration?

Sorry for all the questions :rolleyes:

Could I edit the file on the phone using this:

or am I trying to be to clever?

[Guest rayraven]

Yes you can use root explorer to edit build.prop

[Guest That-Guy]

Thanks, sorry for all the questions just wanna get it right.

Do I use root explorer to copy the file to sd card so I can edit from the computer or is there an editor to edit the file directly on the phone?

[Guest rayraven]

In root explorer, tap and hold on the file, you'll get an option to edit the file. Choose the inbuilt text editor.

be careful with what you do ! cause i made a mistake and had to flash my phone !!

i was trying to enable HW acceleration as well ! edited the file, copyed the new "gralloc.msm7k lib" for the artifacts...

restart...and BOOOM there was nothing on the homescreen !!! LIKE ALL GONE !

What's "gralloc.msm7k lib" and "Artifacts" ?? I thought I just needed to edit debug.sf.hw ??

[Guest flopyro]

artifacts... how should i explain it, it's like a litte distortion of your screen, they appear like little flees, and your icons appear choppy.

the standard Rom does not have HW acceleration enabled, so the processor does not have the "instructions" written in his "drivers" -> "gralloc.msm7k.so"

so in order for the little distortions to disapear, after enabling the HW acceleration, you need a new "library"(driver) for the processor, and that one you need to copy from a rom with HW accel. enabled.

it didn't work for me .... I donno what to say...

why dont u flash a new rom ? ... i know U'R SCARED right ?

it's easyer ! belive me !

Already flashed it once so thats not a problem, its just that fact I have spent the last week setting the phone up just how I like it.

Will I notice a huge difference with hardware acceleration enabled?

[Guest That-Guy]

OK This is starting to annoy now.

I installed root explorer and the phone pops up with errors saying processes are un-responsive etc, so had to un-install that.

I then installed Titanium Backup Pro and faced with the following error:

"Sorry I could not acuire root privileges. This application will *not* work! Please verify that your ROM is rooted and includes BusyBox, and try again"

I know the phone is rooted as it is required or "AdFree" to run and I have the Superuser icon, What is BusyBox? and how do I install?

Try running this before titanium/root explorer, i know one of the Froyo roms and an issue with the SU binary not having the correct permissions and that caused the same kind of problems

(Taken from the 2.2 alpha thread)

Regarding busybox press the problems? button on titanium backup once you get into it, it will download the required busybox files.

Clicked the Problems button, it downloads something but fails to install B)

[Guest That-Guy]

OK re-rooting with the new Universal Androot allows Titanium Back to load perfect.

Root Explorer still kills my phone.

Guess the only option is to re-flash B)

What if we would to remove debug.sf.hw from the build.prop? Wouldn't that enable the default behaviour of the blade?

I'm running Seb's r5 which by default has debug.sf.hw=0, I commented the line out and it seems to have enabled hardware acceleration because I've got the artifacts back again. I know the Modaco ROMs have a modded gralloc.msm7k.so that's supposed to get rid of the artifacts but tbh if it wasn't for the artifacts I couldn't really notice any difference between on and off.

Gotta try it in the games B) speedx, minisquadron and backbreaker footbal are great examples of how hw accel on can improve the speed.

I have my ROM (slightly modified sebastian404 r6) with hw on and the modified gralloc.msm7k.so and now I enjoy my phone even more. The gralloc files really solves the artifacts although hw accel on makes it reboot sometimes (by sometimes I mean twice since I have the phone and tried hw accel on).

Angry Birds also stutters in some of the more complex levels without hardware acceleration B)

I was going to try this rom: r6: Sebastian404's de-orangeated ROM

I looked at the rom above because on the comparison table here it says it has hardware acceleration enabled. But when you look at the build.prop file is has this "debug.sf.hw=0" which I thought mean it was disabled.

Can anyone confirm if it is enabled or disabled by default?

HW acceleration is disabled on that ROM, Sebastian404 does not make any tweaks from stock.

Indded it's disabled. Seb's roms all have debug.sf.hw=0

Thanks, I guess someone needs to update that post B)

I guess the closest to stock rom with hardware acceleration would be the lite version of this one:

What do others think?

[Guest Ricey155]

bookmarked

i was after some info on this also, i guess there inst an easy option to find out if its enabled or not

im using alpha 4 rom best check see if its enabled there :)

[Guest AceOfSpades]

Does the hardware acceleration affect the speed of the ui at all, for example menu scrolling? Does it enable internet pages to render faster or is it just for games?
