[Sugar-devel] Replacing Xephyr with VNC

[David Leeming]

Not sure if this stating the obvious, but I have been using VNC Launcher
activity very successfully in training and demos. Works well with UltraVNC
Viewer running on a Windows or Linux laptop on the eth1 network. A small
config change needed to get the mouse click to work remotely. It's very
stable andf you can demonstrate/project a fully collaborating XO.

Subject: [Sugar-devel] Replacing Xephyr with VNC

Hi!

As many of you are probably aware we're having considerable trouble [1,2]
with Xephyr, the X server currently used in sugar-emulator.
I've finally managed to get VNC working for sugar-emulator on all of the
distros supported by sugar-jhbuild and would like these changes to be merged
in mainline. [3]

Dependencies added:
* Debian/Ubuntu: vnc4server, xvnc4viewer
* Fedora: tigervnc, tigervnc-server
* Ubuntu: lsb_release (for triggering a Ubuntu-specific workaround)

Dependencies removed:
* Xephyr


User experience changes:
+ non-US keyboards are working properly
* F8 is mapped to VNC menu (can send plain F8, but not <modifier>+F8)
* VNC grabs the keyboard in full screen mode
    + no window manager interference
    - no way to switch away from VNC (other switching to window mode using
F8 menu)


Other changes:
+ SL#17 [4] fixed


Tested on:
* Debian squeeze (for several months)
* Ubuntu Intrepid
* Ubuntu Jaunty
* Fedora 12
