| x11vnc no response to taps on left of
screen |
 
United States |
2007-04-07 18:27:20 |
Well, I finally got something to work. I was getting pretty
discouraged. I
installed x11vnc and connected to it with Krdc. I get a
nice display of
the N800 desktop and I can tap on most things and get an
appropriate
response. However, when I tap on items on the left side of
the screen (in
the task navigation area) such as the globe, nothing
happens. Also, the
N800 has an annoying habit of dropping the WiFi connection
because it is
not detecting any taps on the screen. I wonder whether
connecting with
usbnet would be a good way to avoid the latter problem.

My theory was that the N800 drops the WiFi connection when the screen blanks, and I know that the screen blanks when the N800 does not detect any user events. So my guess was that the problem was due to lack of taps or button pushes, not inactivity of the VNC connection. I did not mean to suggest that dropping WiFi was related to my other question about insensitivity on the left side of the screen. My theory may be completely wrong. It seems to me that VNC activity is insufficient to prevent the screen from blanking, but perhaps the N800 drops the WiFi connection when it goes into a state beyond blanking the screen, and perhaps VNC activity is sufficient to keep the N800 out of that state. What I see is that my VNC viewer becomes catatonic after a period of inactivity and at the same time I can no longer ping the N800. I have to wake up the N800 by tapping the screen. The N800 then reestablishes the WiFi connection and I can again use the VNC viewer. It's possible that I lose the connection to my VNC viewer after a period of both no user events and no VNC activity. In any case, I would like for the VNC connection to stay alive so that I don't have to physically access the N800. Is there a way to configure the N800 so that it stays fully awake as long as it is on external power?

Interesting to know that you see the same behavior, even though we are using different VNC viewers. Sounds like a bug in x11vnc, no?
I looked at the HowTo for setting up usbnet (https://maemo.org/maemowiki/HowToSetUpUsbNetworkingDebian). I hope that I don't have to go that way (although I suspect that usbnet would work faster and more reliably than WiFi) because there is much in that document that I don't understand. For example, step 5 says:

Once again, I am baffled as to how I am supposed to modify the contents of a file on the N800. Is there a console that permits me to navigate to the appropriate directory? Is there an editor that permits me to make the necessary changes? Am I supposed to install these things? I hate to expose such prodigious ignorance, but I must have missed something in the tutorial.
My goal is to get VNC working (pretty much there) so that I can view and interact with the N800 from my desktop system. Then I would like to get NFS working so that I can mount the desktop system on the N800. I will do program development on the desktop, and test the program by switching to the VNC viewer to run the program on the N800. The transfer of the program to the N800 would happen transparently thanks to NFS. I need to mention that I am writing the program in Python, so there is no issue of cross-compiling. As far as I can tell, I don't need scratchbox, although I am installing it now anyway.
Speaking of Python, there's something else I haven't figured out: How do I run Python? It's already installed, right? Again, I seem to need a console so that I can run the python command -- or a Python shell.

At least on my N770 I have the possibility to use the
"Connection manager"->Tools->Connectivity
settings
This window has an "Idle times" tab, I have set
"WLAN idle time" to Unlimited.

Where did you get x11vnc for the N800? Or are you using the
770
version?

I don't know why.

I can see how that would be annoying. I've experienced that
with ssh
sessions to the 770: a short while after it blanks its
screen the ssh
session freezes until I tap to wake the tablet up.

I doubt it.

Hi Jeff,
For the Python question, all you need is the 'xterm' package. It's called OssoXterm or something. I don't have the URL, but it was real easy to find on the maemo site. I've reflashed my N800 3 times and found it there (not reflashing due to problems.. testing ported software on it).
I get the same problem as you with the x11vnc not responding to clicks on the docking/application bar. It's frustrating as heck because it was inversely so neat to even find a vnc server for this. It is definately an x11vnc issue as I tried 2 different VNC viewers, and if I maximize applications I can still register clicks in that area.
If x11vnc worked 100%, it would be VERY useful. For example, my LInux desktop machine can save VNC sessions to a file, and convert them to AVI, which is much more powerful for end users than simple screenshots. I'm looking forward to a solution for this also.

I have played with this I was using the mud x11vnc found
here
http://box.mmapps.net/~keesj/mud/repo
sitory_it2007/x11vnc_0.8.4-1_armel.deb
. The only problem I had was that I had to start the program
again
after each connect .
The only real problem is that the framerate was very slow
:(
perhaps vnc2swf must also run on the n800 (there is an old c
based
version somewhere)

I have several more problems with this package. First, it
requires the
installation of libxdamage1. Second, it does not create an
entry in the
task navigator, so I must start it from a command prompt.
There's the
problem you mentioned. Finally, my mouse pointer disappears
when it enters
the viewer window, so I don't know what I'm tapping on.
Only the last one
is serious. Is it possible that I got the wrong
libxdamage1? The version
that I installed is 1:1.0.3-2osso1.

This was the key that I was missing, believe it or not.
Once I installed
xterm I was able to configure ssh and get it working. With
ssh working, it
isn't clear to me that I am going to need xterm much, but I
couldn't have
gotten to this point without it. Thanks for the
suggestion.

I found it at this site:
http://mike.saunby.googlepages.com/x11vncfornokia7702
The web site claims that the package is for both the 770 and
N800.

You would like a home applet or something?, I played with
wxglade and lua
to create interfaces, but for this a small c program would
perhaps be better

Yes this is not a very nice feature , is there a software
mouse
implementation we could enable. I have the same problem when
using
syngery(an oneko is not that good of a mouse pointer )

I just tried to install it on my n800, yes the required
version is 1.0.3-2osso1
After installing the Bora SDK Repository 3.0 from
download.maemo.org
the installed version is libxdamage1 (1.0.3-2osso1), I just
created a
small movie to show vnc2swf working(it's not the n800 that
is slow but
the network..)
