LunaCE on Pre3

From WebOS-Ports
Jump to navigation Jump to search


This page is dedicated to running the WOCE version of LunaSysMgr on webOS 2.x devices.

The information here was collated using WOCE on a Pre3, so it may not be accurate if you're using a different device.

The page will be updated to reflect new findings as and when they surface.

What Works

Touch Input

Ringer Switch


Status Bar

System Menu

What 'Sort Of' Works

Virtual Keyboard

Opens and works w/password unlock

Characters are all garbled

Doesn't hide/show when slider is opened/closed in a text field

Opens and crashes in maximized cards (lock & unlock when maximised to show keyboard button):

Hardware Keyboard

Enter & Backspace work w/password unlock, other keys unresponsive.

Doesn't wake the screen from lock.

Crashes on input in card view/launcher with the following:

** Message: dockStateTransition: transitioned to state 1

Power Button

Screen lock/unlock works

Press-and-hold doesn't function (may be to do with app launching)

Volume Keys

Indicator appears on-screen, changes boot sound volume.

Keyboard clicks & card 'swoosh' sounds unaffected.

UI Layout

Status Bar dimensions are too large.

(The above can be fixed by replacing /etc/palm/luna-platform.conf with LunaSysMgr/conf/luna-mantaray.conf)

Quick Launch icons overflow over the launcher button.

Launcher displays 2 columns instead of 3.

Everything's tiny due to lack of scaling.

Just Type bar is too big for the screen.


Flick handling is intermittent, sometimes works, sometimes doesn't. Somewhat random.

What Doesn't Work

App Launching

Icons glow & cards appear, but solid white with no content.

Cards never reach MaximizeState

Core apps (Phone, Contacts, Mail, etc) don't even get a card.

Voice Dial

Timeout sound plays some seconds after triggering via icon/volume keys.

Otherwise non-functional.

Just Type

When tapped, search bar & quick launch fade out to make way for just type, but it never appears.

Cannot go back from there, as the gesture area doesn't work.

Gesture Area

No response, CoreNavi LED doesn't function.

Logs complain about not being able to find a target for the gesture:

** (LunaSysMgr:8396): WARNING **: QWarning: QGestureManager::deliverEvent: could not find the target for gesture


First Use Mode?

Hangs at the HP logo while wiping /media/internal/.palm and setting up core apps.

Presumably dependent on First Use app, which doesn't launch currently.


Screen does not rotate,

LunaSysMgr throws HAL errors relating to it:

webos-device user.err LunaSysMgr: module (halSensorOrientationDefault.module) does not exist
webos-device user.err LunaSysMgr: in /lib/hal/modules
webos-device user.err LunaSysMgr: nor in  /lib/hal/modules.mock
webos-device user.crit LunaSysMgr: {LunaSysMgr}: Unable to open Sensor : [virtual hal_error_t HALConnectorBase::openSensor() : 103] : [HAL Sensor Type = 2]
webos-device user.crit LunaSysMgr: {LunaSysMgr}: Unable to open the requested sensor type :

Before continuing, be sure to understand that this version of LunaSysMgr is NOT usable in it's current state. It is here for the purpose of further development, and you will have to doctor your device to get it back to normal functionality.

Also, if you're attempting to install LunaSysMgr CE on a Pre2 or earlier device, note that the Qt4.8 libs are very large and may not fit into your rootfs. In this case, it is recommended to either use either Tailor or the webOS Internals Meta Doctor to increase the partition's size.


Transfer the required libraries

Open a Terminal and cd into woce-build/rootfs/armv7/usr/lib/

Compress the libraries into a .tar file for easy transfer (-h to follow symbolic links, otherwise breaks)

tar -chvf lunaLibs.tar libQt*

Copy the files to the device

novacom put file:///usr/lib/lunaLibs.tar < lunaLibs.tar

Extract them

cd /usr/lib
tar -xvf lunaLibs.tar
rm lunaLibs.tar

Copy libqpalm to the Qt Libraries folder mkdir -p /usr/plugins/platforms

cp ./ /usr/plugins/platforms

Link the new libraries

ldconfig -v

Close novaterm


Transfer the required HAL modules

Open a Terminal and cd into woce-build/rootfs/armv7/lib/hal/modules

Compress the libraries into a .tar file for easy transfer

tar -cvf lunaHAL.tar ./*

Copy the files to the device

novacom put file:///lib/hal/modules/lunaHAL.tar < lunaHAL.tar

Extract them

cd /lib/hal/modules/
tar -xvf lunaHAL.tar
rm lunaHAL.tar

Close novaterm


Transfer the required Luna modules

cd into woce-build/rootfs/armv7/usr/lib/luna

Compress the libraries into a .tar file for easy transfer

tar -cvf lunaModules.tar ./*

Copy the files to the device

novacom put file:///usr/lib/luna/lunaModules.tar < lunaModules.tar

Extract them

cd /usr/lib/luna
tar -xvf lunaModules.tar
rm lunaModules.tar

Close novaterm


Transfer the required Luna resources

cd into woce-build/rootfs/armv7/usr/palm/sysmgr

Compress the resources into a .tar file for easy transfer

tar -cvf lunaRes.tar ./*

Copy the files to the device

novacom put file:///usr/palm/sysmgr/lunaRes.tar < lunaRes.tar

Extract them

cd /usr/palm/sysmgr
tar -xvf lunaRes.tar
rm lunaRes.tar

Close novaterm


Prevent LunaSysMgr from crashing on startup

Option A: Clone a git repository

git clone git://
git checkout lsm-pre3

And to pull down the latest changes

git pull origin lsm-pre3

Option B: Download a patch

Download and apply the following patch to your own LSM sources:

cd /path/to/LunaSysMgr
curl > lsm-pre3.diff
patch -p1 < lsm-pre3.diff

Build and Run

Modify woce-build/support/, changing MACHINE=topaz to MACHINE=mantaray

Build LunaSysMgr, noting that the output will now be in the release-<MACHINE> folder (for instance, Pre3 would be release-mantaray)

Backup your old LunaSysMgr

stop LunaSysMgr
mv /usr/bin/LunaSysMgr /usr/bin/LunaSysMgr.old

Upload the new LunaSysMgr

novacom put file:///usr/bin/LunaSysMgr < /path/to/compiled/LunaSysMgr

Run the new LunaSysMgr


Getting apps to start

While technically it is possible to get apps to actually start, there's something crashing in the visuals area, so we can only see it actually working from the logs at startup.

To get apps "operating", you'll need the from 3.0.5. This also requires BrowserServer also requires libWebKitLuna, and will need a replacement to operate for it's "SetLocaleCollator" function, and a new for it's "MallocTrim" function. requires to function, as well.

After getting everything operating, libnapp will crash Luna out with the following backtrace:

  1. 0 0x3610422c in NWindow::SetBuffer(int, NWindowBuffer*) () from /usr/lib/
  2. 1 0x38d99700 in WSEGL_SwapDrawable(void*, unsigned long) () from /usr/lib/egl/
  3. 2 0x37f0e738 in IMGeglSwapBuffers () from /usr/lib/
  4. 3 0x36145a7c in QEGLPlatformContext::swapBuffers() () from /usr/lib/
  5. 4 0x3614609c in QEglFSWindowSurface::flush(QWidget*, QRegion const&, QPoint const&) () from /usr/lib/
  6. 5 0x367f7280 in QWidgetBackingStore::flush(QWidget*, QWindowSurface*) () from /var/lib/libQt/
  7. 6 0x36a43950 in ?? () from /var/lib/libQt/

Attempting to copy in new versions of the dependencies for libnapp will result in much earlier crashing:

try copying in new /usr/lib/egl/ ... results:

    • (LunaSysMgr:17141): WARNING **: QWarning: Could not open egl display
    • ERROR **: QFatal: EGL error

crash, very early in startup.
