Porteus

The following operation takes almost one minute in a KDE session:
In an LXDE session or openbox session, the window of xterm appears immediately. When I tried Porteus-XFCE-v1.2-rc2-i486, and when I was using Porteus v1.1, there was no problem. So the problem of slow X11 forwarding is peculiar to KDE of Porteus v1.2.

Anyone with ssh server available that can confirm this?

in my case xterm appeared immediately but kwin crashed:
link

steps to reproduce:
a) start porteus in any mode on your PC
b) enable X11 forwarding in /etc/ssh/sshd_config and start sshd
c) launch Porteus in Vbox and boot to Trinity desktop
d) while in vbox session: run 'ssh -X guest@xxx.xxx.xxx.xxx'
e) once logged in on a remote machine run 'xterm' command

result: xterm opens but kwin crashes and window decorations are gone.
same scenario works with LXDE desktop in virtual session.

Same here.

I tested this case using various ssh servers.

I thought I would try another distro using Trinity to see if it has the same problem. But according to the distrowatch search, Porteus is the only distro which uses Trinuty. I will try some Debian based distro and apt-get install Trinity.

I tested this on Debian 6.0 after installing Trinity Desktop environment. The results were all good.

The TDE version installed to Debian 6.0 was 3.5.13, while that of Porteus is R 14.0.0[DEVELOPMENT].
