So, there's the problem with the X2 having the volume buttons not work when it's locked. I just got one a couple days ago, and decided to poke around to see if I could get it going. I messed with my old Nexus One and reassigned the Search button to the camera, so I started with the keylayout directory. Well, after some experimenting, I got it going. While you have to press the button for each incremental change in volume, it beats having to turn the device on.
Note: I can't post links due to a low post count. So my lack of helpful links is the forums' fault, not mine. My apologies.
What you'll need before you begin;
1) Root access. The X2 can be rooted with Gingerbreak.
2) A file manager. I use Root Explorer.
2b) If you're manually applying the changes, and you're using a file manager without one built-in, you'll need a text editor. Root Explorer has one, so...figure it out.
The Long Method
=Step One=
Navigate to "/system/usr/keylayout". The file we're working with is "tegra-kbc.kl"
=Step Two=
Mount the file system as read/write, make a backup of tegra-kbc.kl(I'm partial to adding a .ori to the end, but that's me), and open tegra-kbc.kl in a text editor.
=Step Three=
Lines six and seven, right below Camera, are the volume buttons we're looking for. We're going to append "WAKE" at the end of the line, to tell the phone to listen when they're pressed. Mine looks like this;
key 115 VOLUME_UP WAKE
key 114 VOLUME_DOWN WAKE
Obviously, it's not too picky about spacing. So the sky and your anal-retentiveness is the limit.
=Step Four=
Save the file, set correct permissions if they got mangled somehow(rw-r--r--, for reference), and restart.
The Short Method
=Step One=
Download the needed file. Take any public dropbox file link, and replace the end with "/u/3487229/Android/tegra-kbc.kl"
Look, I'd just give the link, but low post count and all. My apologies.
=Step Two=
Make a backup of, then copy the file over /system/usr/keylayout/tegra-kbc.kl
=Step Three=
Reset any mangled permissions(rw-r--r--, for reference), and restart.
Awesome.

Worked a champ. Was trying to figure out how to do this last night.
Could someone paste the tegra file. I think I may have deleted it while attempting to make a backup. Many Thanks!

Just tried this and did not work. Looking at file now, says WAKE after each, restarted and still doesn't work.
This may sound dumb, but I don't think this method "fixed" anything. I accidentally deleted the tegra-kbl.kl file but my volume can be adjusted while locked. The trick is to press volume multiple times rather than holding to adjust. FYI I never got a chance to adjust the file per the OP. Lemme know if this works for anyone else.
ALSO I STILL WOULD REALLY APPRECIATE SOMEONE POSTING THE TEGRA-KBL.KL FILE. THANK!

Does it match the above, where there's at least one space between WAKE and the word preceding it? Also, are the permissions correct?

That's how this works when implemented; you can't just hold down volume, but each click changes the volume by one increment.
I'm not sure how you got to where you are; when I accidently deleted the keylayout file on my Nexus One, none of the physical buttons worked, except the power button to power it on.
That was a fun one to recover from.
While I see someone else posted the entire original file in another thread, let me post what mine looks like, for comparison.

@Elite49;
Here's what I'd do, on your device. I know we might be treading old ground, but just to rule anything out, try this;
1) Download the attached file. Lop off the file extension so it's just "tegra-kbc.kl"
2) Copy it, and head over to /system/usr/keylayout. Take the existing "tegra-kbc.kl" and put on a file extension that renders it inoperable(I like .ori, but that's just me).
3) Paste the downloaded "tegra-kbc.kl" into the keylayout folder.
4) Check permissions and ownership. Ownership needs to be root on both group and user, and permissions should be rw-r--r--.
5) Power-cycle.
6) Try it out. The quickest way, with that file, is to hold down the search key. If it's using that key layout file, after a few moments your camera app should come up. If it does, then your volume buttons should also be usable when your device is locked.
If you don't want camera on your search key, here's how you change it back. I only suggest doing this after you've verified your device is using this key layout file. If you do it before, then we're back to square one because we're only testing the volume buttons. This's changing two functions, making it easier to see whether it's a hardware or software issue.
1) Open /system/usr/keylayout/tegra-kbc.kl
2) Find CAMERA. Change the key from 211 to 217.
3) Find SEARCH. Change the key from 217 to 211.
4) Save file, check ownership and permissions, reboot. Ta-da.
Thanks!
This marks a huge negative off of my list! I think I will keep it now.

Hello!
My problem is, that i have bought a new car holder for my x10.
Now i have the problem, when i slip in my phone, the hardwarebutton for the camera is permanently pushed.
Does anyone have an applikation, which switches of the hardwarebutton?
Many thanks,
Greetings
- Install ButtonRemapper (root needed)
- open it, click on "focus" in the list and then pick "dpad center" / "none"
if it presses enough to trigger the camera and not just the focus, do the same for camera in the list.
- in ButtonRemapper settings, uncheck "boot monitor" and check "hot reboot".
- click Apply, your phone will reboot after a few seconds.

Thank you a lot, zorglub08!!
It works perfectly.
By the way, what activates the dpad center?
The d pad center doesn't activate anything in the home, that's why I picked it, in practice in just just disables the button. If you launched an emulator or some app that supports a hardware directional pad, it may do "Enter"/"OK". I didn't try though, on my phone, I didn't find and app that used it.
I was going to PM this to you, but since you made another thread i'll post it here.
To properly disable the camera button, you must edit the es209ra_keypad.kl file. This file controls how the Android OS responds to the hardware buttons.
Use Root Explorer (or any other root file manager app) and navagate to /system/usr/keylayout/ and open the es209ra_keypad.kl file for editing. I am doing this on 2.3.3, so the file may be different depending on your ROM. Either way, it is easy to tell which lines need editing.
Once you have the file open, place a hash (#) in front of the "CAMERA" and "FOCUS" lines as follows:
Code:
key 115 VOLUME_UP WAKE
key 114 VOLUME_DOWN WAKE
key 229 MENU
key 59 MENU
key 213 MENU
key 102 HOME WAKE_DROPPED
key 158 BACK
key 107 ENDCALL WAKE_DROPPED
key 62 ENDCALL WAKE_DROPPED
key 231 CALL WAKE_DROPPED
key 61 CALL WAKE_DROPPED
key 116 POWER WAKE
#key 212 CAMERA
#key 215 FOCUS
key 226 HEADSETHOOK
Once you have edited the file, reboot your phone.
This effectivly stops Android from even seeing that the camera button exists, hence, the camera button will do absolutly nothing to the phone. If you change ROMs, you will have to do this again.
Cheers to Pierre Duc who created the thread about stopping the home button from waking the phone, otherwise I wouldn't even know that this file exists.

This is a little example for how to use walkman key as search key so with this u can use any app u want with that kay by just using an app that changes search key behavior
1.Using any file explorer with root go to /system/usr/keylayout/
2. Edit with texteditor file: pm8058-keypad.kl
It should look like this:
Code:
# this corresponds to kernel/arch/arm/mach-msm/keypad-coconut.c
#
# defines for values are in frameworks/base/include/ui/KeycodeLabels.h
key 115 VOLUME_UP WAKE
key 114 VOLUME_DOWN WAKE
# KEY_HOME
key 102 HOME WAKE_DROPPED
# CAMERA Related Key
key 212 CAMERA
key 528 FOCUS
# WALKMAN key
key 200 VENDOR_1
At the bottom of the file u can see:
Code:
# WALKMAN key
key 200 VENDOR_1
VENDOR_1 is used to tell android which action the key will take
so if we change VENDOR_1 to SEARCH wolkman key will be recognized as a SEARCH key.
So the file after changing it should look like this:
Code:
# this corresponds to kernel/arch/arm/mach-msm/keypad-coconut.c
#
# defines for values are in frameworks/base/include/ui/KeycodeLabels.h
key 115 VOLUME_UP WAKE
key 114 VOLUME_DOWN WAKE
# KEY_HOME
key 102 HOME WAKE_DROPPED
# CAMERA Related Key
key 212 CAMERA
key 528 FOCUS
# WALKMAN key
key 200 SEARCH
After editing the file save it and reboot device.
U can map any action to this kay that android will recognize for the rest of actions availdable u can use qwerty.kl as refrance:
Code:
key 399 GRAVE

And the most useful with Walkman:
Code:
key 200 MEDIA_PLAY_PAUSE WAKE
key 201 MEDIA_PLAY_PAUSE WAKE
key 166 MEDIA_STOP WAKE
key 163 MEDIA_NEXT WAKE
key 165 MEDIA_PREVIOUS WAKE
key 168 MEDIA_REWIND WAKE
key 208 MEDIA_FAST_FORWARD WAKE
When changing action taken by walkman key to one of the above like MEDIA_PLAY_PAUSE its advised to add this WAKE too if u want to use this button when phone is sleeping
So it should look like this:
Code:
# WALKMAN key
key 200 MEDIA_PLAY_PAUSE WAKE
Hope this helps
wow ...
its great .... tks tks
very good work
thanks

so if i want to launch poweramp application with this walkman button, how do i do that? will simply mention app name work?
key 200 POWERAMP
If u want to assign poweramp app to Walkman key the only option for now is to assign it as search key and then with app for example: LaunchKey assign an app to long press search key.

Sent from my WT19i using XDA
in cm7 use the above method to allocate search to walkman key and then go to settings, cm settings, input, search key behavior and choose whatever app you want for the long press action, for the short press whenever a search is possible, that will turn up instead of the app.

My dad's Droid X2 was having issues so he got a new phone (Note II, the lucky bastard >_>) and gave me his old phone. Messing with it a little before I activate it on Verizon, I realized that the only thing wrong with it was the back button - its worn out and keeps clicking itself over and over again. To do anything with the phone I need to mash the back button for 15+ seconds while the screen is off/on the home screen.
I haven't done anything with the phone yet, its still bone stock, fully updated, not even rooted yet. In its current state its nearly unusable as a daily driver, but I figure if I can flash ICS/JB, activate the onscreen keys, an fully disable the hard keys, it'll be good to go - a decent replacement to my Droid charge (which I love to pieces but is so lageriffic its getting hard to use)
My problem is, none of the roms say anything about this. My experience with cyanogenmod/AOKP is limited to a few unofficial alpha roms for my tablet, so I really don't know. I found this, which I think might work for what I want , but I don't know if its compatible with the Droid X2, especially with the rom I was really looking into, paranoidandroid. Though I will honestly accept any 4.0+ rom. This will be my daily driver, if I can get it to work, so I do care about stability. Just not sure where to start or how to go about this. I'd like to consider myself a fairly advanced ROMer, so if it gets technical, I don't mind in the slightest.
Thank you guys for any help you can provide me.

there are apps on the market that allow button remaping but if you wanna try something like cyanogen or miui on the dx2 try this Soft key mod for CM/Miui it has a flash able zip for disabling and reenabling the hardware buttons and the same for the software buttons works like a charm for me but im never on one rom long enough to really enjoy it.
Check out an app in the Play Store called "Button Savior".

OK, so the hardkey issue seems to have mysteriously alleviated itself..
guess i'm just looking for the most stable 4.0+ ROM now.
I had an X2 with a failed back key also. In order to make the phone bearable while waiting for the replacement to arrive, I edited the keyboard file and changed the "search" button to the "back" button. You'll need to be rooted to do this. From a file explorer app (I use Astro or AntTek Explorer), browse to \system\usr\keylayout and open the tegra-kbc.kl file with a text editor from within the phone. I used File Editor, which I think is stock within the phone. When open, you'll see a whole list of keys, but you'll only need to concern yourself with 158 and 217.
Here's a section of the file so you know what I'm talking about.
key 102 HOME WAKE
key 139 MENU WAKE_DROPPED
key 158 BACK WAKE_DROPPED
key 212 FOCUS
key 211 CAMERA
key 115 VOLUME_UP
key 114 VOLUME_DOWN
key 217 SEARCH WAKE_DROPPED
key 28 ENTER
Click to expand...
Click to collapse
You'll want to make changes to the lines I've bolded so they look like this:
key 102 HOME WAKE
key 139 MENU WAKE_DROPPED
key 158 BACK WAKE_DROPPED
key 217 BACK WAKE_DROPPED
key 212 FOCUS
key 211 CAMERA
key 115 VOLUME_UP
key 114 VOLUME_DOWN
# key 217 SEARCH WAKE_DROPPED
key 28 ENTER
Click to expand...
Click to collapse
So now, both the "back" button and the "search" button will do the same thing.
You can always disable the original "back" button altogether by putting a # in front of the 158 line like this:
key 102 HOME WAKE
key 139 MENU WAKE_DROPPED
# key 158 BACK WAKE_DROPPED
key 217 BACK WAKE_DROPPED
key 212 FOCUS
key 211 CAMERA
key 115 VOLUME_UP
key 114 VOLUME_DOWN
# key 217 SEARCH WAKE_DROPPED
key 28 ENTER
Click to expand...
Click to collapse
After making the changes, save and close the file, then reboot your phone.
Let me know if you have any questions.
This is perfect, thank you so much.
I found the soft keys and installed that, so I'd be plenty happy disabling all 4 hard keys at the bottom. What would be the proper way to go about doing that, using this method?
If you wanted to disable the buttons, you'd simply place a # in front if the line you don't want read by the software. You better make sure the soft key app is rock solid though.
Change it from this:
key 102 HOME WAKE
key 139 MENU WAKE_DROPPED
key 158 BACK WAKE_DROPPED
key 212 FOCUS
key 211 CAMERA
key 115 VOLUME_UP
key 114 VOLUME_DOWN
key 217 SEARCH WAKE_DROPPED
key 28 ENTER
Click to expand...
Click to collapse
to this:
# key 102 HOME WAKE
# key 139 MENU WAKE_DROPPED
# key 158 BACK WAKE_DROPPED
key 212 FOCUS
key 211 CAMERA
key 115 VOLUME_UP
key 114 VOLUME_DOWN
# key 217 SEARCH WAKE_DROPPED
key 28 ENTER
Click to expand...
Click to collapse
You can also use Bootstrap Recovery to check what each key is. Select Advanced --> Key Test. To get out of the key test, press Power, Volume UP, and Volume DN at the same time, and the phone will reboot.

I told you the wrong file name. You'll want to edit the tegra-kbc.kl file located in the same directory. I'm sorry about that.
OK, thank you! I'll let you know how it goes.
And they're the OS soft keys from jellybean, so nothing to worry about.

OK, disabled them! Thanks!
I'm considering assigning the search key to the camera shutter. However, if I do this, I don't want it to launch the camera app, just to take a picture if the camera is open. Is there a way to do this?
I have found many examples of modding the the key file in System\Usr\Keylayout to remove the wake option from key 102, but in eclipse 2.3, there are 6 .kl and 4 of them have key 102 mapped to wake in them. I am unsure if I need to remove wake from key 102 in all or some of them.

OK after trial and error, removing the word WAKE after the 102 key entry in System/USR/Keylayout/Tegra_kbc.kl file prevents the home button from waking the phone. So now it a lot harder to accidentally turn on the the screen while its in my pocket.

Posting this because it took me a while to get it done. Why do it? Because the placement of the physical buttons straight-across each other on opposite side of the phone makes it awkward and annoying to use the power/wake button without also hitting/squeezing the vol up/down button. And because volume can be adjusted otherwise using touchscreen in Settings.
Root phone. Install root-enabled file manager app (I use Total Commander, various others work, too.) Go to /system/usr/keylayout/gpio-keys.kl
Mount read/write, open file in editor, etc
Comment-out the two lines:
key 115 VOLUME_UP
