Description
We've had enough trouble with Xephyr. This patch replaces it with VNC.
Uses VNC4 on Debian (derivatives), TigerVNC on Fedora (derivatives). The latter one has been fixed upstream (already in F11+F12) w.r.t. the keymap bug.
Tested on:
- Debian squeeze (for several months)
- Ubuntu Intrepid
- Ubuntu Jaunty
- Fedora 12

Found by bertf: Cursor is smaller in Etoys if running with VNC instead of Xephyr. Once Etoys has been started, the cursor stays the same even after switching windows.
I've also sometimes noticed minor visual artifacts, e.g. the Frame corners having a slightly different color than the Frame edges/"bars" (using raw encoding, full color, vnc4server 4.1.1+X4.3.0-35 on Debian squeeze).

Hi,
Playing around with this some more on Ubuntu 9.10, I just noticed the obvious: since the mouse isn't restricted to the sugar emulator window size (even in full-screen mode), it's hard to get the frame to appear by moving the mouse to the edge/corner of the screen. That may be a problem,
but one can use Alt-shift-F to toggle the frame.

What is the status here?
comment:6 Changed 13 years ago by erikos
- Milestone changed from 0.88 to 0.88.x
As it is no show stopper...
comment:7 Changed 13 years ago by erikos
- Milestone changed from 0.88.x to 0.90
As discussed with Sascha on irc, we move it to 0.90. We aim to land it early so we get a lot of testing.

I'm quite happy with Xephyr, and I'm afraid VNC would be slow.
Can we keep both options available?
comment:9 Changed 13 years ago by quozl
Bernie, VNC does not seem slow compared to Xephyr, they actually seem the same. Have you any test results to suggest otherwise?

Patch looks great, sugar-emulator runs even better. Please push after checking I did the merge correctly and adding anything to jhbuild in case its needed.
May be good to add a note to http://wiki.sugarlabs.org/go/0.90/Notes so we remember to mention in the 0.90 release notes that packagers need to replace the Xephyr dependency for XVnc.

Is everything done here? Is the ticket just left open so we can add a note to the 0.90 deps?
comment:12 Changed 13 years ago by sascha_silbe
I didn't commit yet because I was rather busy. Do you still want this in 0.90 or postpone to 0.92?

Emulator is pretty annoying with any non-english keyboard layout.

Replying to icarito:
Emulator is pretty annoying with any non-english keyboard layout.
I managed to fix it for me by adding
setxkbmap -rules evdev
to my ~/.sugar/debug file. Arrow keys work now for me, as well as intl chars.

- Resolution set to fixed
- Status changed from new to closed
sugar-emulator is gone, sugar-runner deals with xkb
Sascha said in #sugar that he has some improvements in a branch, but the patch here hasn't been updated.
