[Sugar-devel] Replacing Xephyr with VNC

[Sascha Silbe]

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
