You are right, it is indeed there. It appears that my list was
outdated.
I tried installing it, along with KDE, to see if I could get it
running on the Masquerade Pro (my main reason for doing this is that
I wanted to use kdevelop).
vncserver starts up just fine and I can connect with the vncviewer
from the Windows machine. The KDE desktop also appears and everything
seems to be fine until I actually start some programs. It seems that
whenever there is major change to the screen the vncserver hangs for
a long time, up to several minutes, where the mouse pointer is not
moving and nothing happens. There is no network activity from the
Masquerade while this is going on. Suddenly it will snap out of it
and display the updated screen properly. I managed to get through the
kdevelop setup wizard in this way and it took about 15 minutes.
I am now wondering if this is related to VNC itself or it is an
underlying problem reltated to the Masquerade Pro kernel problems we
briefly discussed earlier on the list. It would seem that the
activities related to running X/vnc involve a lot of concurrent disk
and ethernet activities, and this might provoke a kind of deadlock
situation in the kernel.
When the Masquerade is running programs from RAM with little or no
disk activity and user interaction, performance seems to be very
good, rivalling that of my PII-350 box. But with lots of disk
activity, especially interleaved with ethernet activity, performance
drops almost exponentially.
I would like to investigate this, but unfortunately I don't have much
time at the moment. However, I worked on the Masquerade kernel a lot
when I was working for i-data, so if anyone has any information,
suggestions or ideas, or want information, please contact me.
Also, it would be very helpful if some of you running mipsel-debian
on a non-Masquerade Pro unit to try out the vncserver and mailing me
your results.
