Zonyl: New page: Would you like me to list a step-by-step guide here to using X on the pre via debian chroot and sdlvnc? Or were you planning on getting X running via sdl directly?

== Summary ==
A native VNC client for webOS. Can remote into a VNC server displaying as a native card.

Screenshot is showing the following: 
sdlVNC connected to local Xtightvncserver running from Chroot Debian 
icewm window manager is running along with Firefox all from within the Pre itself.

== Credits ==
Zonyl - initial application and fix for libSDL_vnc. 
zsoc - Various SDL support 
WebOS Internals - Packaging / hosting. 

== Status ==
Initial implementation finished. Its good enough to connect to a local Xtightvncserver, from which you can run any native X11 application.

== License ==

Licensed under the LGPL license.

== Operating notes ==

On-screen parameter usage:
<nowiki>./sdlvnc</nowiki>

Command Line Usage:
<nowiki>./sdlvnc -server 127.0.0.1 -port 5901</nowiki>

'''Virtual Resolution / Panning'''
*Hold down the Gesture area to pan / drag screen

=== Limitations ===
* Virtual resolution is 2000x1080
*Only gets hostname as a parameter (without command line)
*VNC password authentication may not work. I only use it to connect locally without password or via ssh Tunnel.

=== Known bugs ===
*Hostname input without command line is flakey if you type fast. Take is slow
*Drag selecting text seems to crash the underlying vnc library.

== Installing ==

====Requirements====
*libSDL_vnc - also in the repository

*Preware
====Steps====
Until package you need to get the code from the repo and compile yourself.

VNC (Virtual Network Computing)

= VNC on the Palm Pre=

'''NOTE: As an alternative to enabling VNC by following this tutorial, one can use PalmVNC in the Classic emulator with full control. You may download PalmVNC at: http://palmvnc2.free.fr/download.php'''

There is another Native VNC client for the pre now @ http://www.webos-internals.org/wiki/Application:SdlVNC

The following is a proof of concept:

== Prerequisites:==

1. [http://predev.wikidot.com/rooting Root the Pre].

2. [http://predev.wikidot.com/debian Install Debian chroot].

== Demos:==

* [http://www.youtube.com/watch?v=EzLfai2GrKo Video] on YouTube by [http://www.youtube.com/user/nebj00la nebj00la].
* Also see image to the right (or [http://i40.tinypic.com/jhfnle.png here]).

== Instructions:==

1. Download the source tarball, directvnc_0.7.5.orig.tar.gz.
''' NOTE: There is a newer version of directvnc at http://code.google.com/p/directvnc-rev/ ( tarball at http://directvnc-rev.googlecode.com/files/directvnc-0.7.5-test-051207.tar.gz ) that has a feature that might be very useful on the pre, keyboard remapping - http://code.google.com/p/directvnc-rev/wiki/KeyboardMapping - as well as a few others - http://code.google.com/p/directvnc-rev/wiki/NewFeatures - also if someone wants to get GGI working with DirectFB, ggivnc is under current development (unlike even directvnc-rev which is untouched since 2007) - http://www.lysator.liu.se/~peda/ggivnc/ - ggivnc's author is on #ggi on freenode irc. Another option would be to try a GTK-based VNC client, as with [[vala-terminal]].

2. Move the tarball to /usr/local/src/

3. Run the following command from /usr/local/src/:
<pre><nowiki>tar zxvf directvnc_0.7.5.orig.tar.gz</nowiki></pre>

4. A new directory structure should be created. cd to /usr/local/src/directvnc-0.7.5/src/

5. Modify the source of dfb.c (use vi). Remove lines 29, 33, 44, 69 and 83. Here's what each of the lines contains, so you know what we're deleting:
> 29: IDirectFBInputDevice *mouse; #We don't have a mouse.
> 33: DFBCardCapabilities caps; #Won't compile with this line.
> 44: DFBCHECK(DirectFBSetOption ("quiet", "")); #Won't compile with this line, either.
> 69: DFBCHECK(dfb->GetInputDevice( dfb, DIDID_MOUSE, &mouse )); #We don't have a mouse
> 83: mouse->Release( mouse ); #We don't have a mouse

As you can see, we're removing code that will support a mouse and other things that cause the source not to compile. I haven't figured out how to get mouse control. Maybe someone can write a mouse driver that uses the touchscreen. :)

6. Change back to /usr/local/src/directvnc-0.7.5/

7. Run the following command, it will run some checks against the system and get things moving:

'''NOTE: If any dependencies are missing, let us know in irc.freenode.net #webos-internals, we'll update the wiki.'''

<pre><nowiki>./configure</nowiki></pre>

8. Run the following command, it will compile the source code:
<pre><nowiki>make && make install</nowiki></pre>

9. Connect to your VNC host:
<pre><nowiki>/usr/local/bin/directvnc <host><:display></nowiki></pre>

10. Testing: On the PC, take some window (like notepad) and drag it all around the screen, because the Pre won't update it's display until the area of the pre's client focus of the PC window actually sees a pixel change. So until that part of the windows changes you might not seem connected. As with any VNC controller you can expect a bit of lag too this is normal.

{{application
|name=sdlVNC
|type=webOS
|version=Version: 1.0.0 (1 Jan 2010)
|tag=Communications
|screenshot=Application_sdlVNC_Screenshot_1.jpg
|description=

== Summary ==
A native VNC client for webOS. Can remote into a VNC server displaying as a native card.

Screenshot is showing the following: 
sdlVNC connected to local Xtightvncserver running from Chroot Debian 
icewm window manager is running along with Firefox all from within the Pre itself.

== Credits ==
Zonyl - initial application and fix for libSDL_vnc. 
zsoc - Various SDL support 
WebOS Internals - Packaging / hosting. 

== Status ==
Initial implementation finished. Its good enough to connect to a local Xtightvncserver, from which you can run any native X11 application.

== License ==

Licensed under the LGPL license.

== Operating notes ==

On-screen parameter usage:
<nowiki>./sdlvnc</nowiki>

Command Line Usage:
<nowiki>./sdlvnc -server 127.0.0.1 -port 5901</nowiki>

=== Limitations ===
*Does not zoom or pan currently to larger than 320x480 resolutions
*Only gets hostname as a parameter (without command line)
*VNC password authentication may not work. I only use it to connect locally without password.

=== Known bugs ===
*Hostname doesnt resolve DNS correctly. Use IP addresses where you can.
*Hostname input without command line is flakey if you type fast. Take is slow
== Installing ==

====Requirements====
*libSDL_vnc - also in the repository

*Preware
====Steps====
Until package you need to get the code from the repo and compile yourself.

== Repository ==

sdlVNC is housed in the applications/sdlVNC git repository at http://git.webos-internals.org/
