→Problems running under Jaunty (9.04)
There are still lots of non-fatal error messages in the terminal, but it looks like these can be ignored. I used <code>sugar-emulator --dpi=200</code>. Logging in to a Sugar session from <code>gdm</code> worked too.
Previously, it was thought that [https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/325706 a problem with Xephyr and dbus] was at fault, but the above workaround shows that it's a Sugar packaging problem.
