RE: x11vnc -- problems solved
> do you know what if any are the side effects of disabling the use of the pressure information on the N800 as a result of implementing your workaround? In other words does this break some other functionality of the N800, or is the pressure information something that is there as a latent "feature" but not actually used by the N800? I'm sure Nokia folk can answer that better than I, but I think it affects detecting whether a wide area pressure is detected (as by a finger or thumb fleshy part) rather than a touch from a stylus or fingernail. As I don't use fingers directly on the screen (I really hate the grease marks) this makes no difference to me. > If the answer is yes, then it might be possible to write a script to disable it when VNC functionality is needed but to be able to turn it back on when the pressure functionality is needed.

Does indeed mean that the mouse over X11vnc now works on the task manager pane on the left. Many thanks! It doesn't completely fix the problems though .. the other big problem is still there, in that in X-terminal pressing the enter key brings up the thumb keyboard and does not enter the data. One can achieve an Enter by clicking on the window (which brings up the stylus keyboard) and then on the Enter key there, but that's terribly inconvenient.

Adding to the datapoints here, my Access Point is: D-Link Wireless 108G MIMO ADSL 2/2+ Router In general this seems to work extremely well with the N800 .. I can wander all over my house with the N800 and I don't recall losing a connection, whereas a standard laptop with builtin wireless tells to lose connection in the room most distance from the router.

I'm in the progress of porting a relatively small application from Windows (originally OS/2) to the N800 -- a webserver (GoServe) running a Wiki. First I had to port it to Linux (I used ubuntu because the maemo VMware image uses that). That had problems -- but not unexpected (I first used Unix in 1978, and have used several flavours of Unix and Linux on and off since then). Then I had to port it again to Scratchbox X86. A whole set of new problems; different levels of libraries, pthreads just didn't work so I had to make my webserver single-threaded, and several build scripts had to be rewritten Then I had to port it again to Scratchbox ARMEL. Here I had to duplicate all my build and run scripts in bash, because Rexx scripts (which run fine in Scratchbox X86 and on the real N800 device!) cannot call commands or other Rexx scripts in the Scratchbox ARMEL environment. I cannot run the server to test in the Scratchbox environment but instead have to use the real device (hence my interest in x11vnc recently :-). - - - This is a *big* contrast to when I last programmed for a portable device (an early Palm, about 8 years ago). The SDK for that came with a complete emulator for the device, which ran as an application (under Windows, but the host is not important) -- what you saw on the Windows screen was *exactly* what you saw on the actual device. After using it for a few months, I was happy to put out code for others to use without even trying it on the real device. And, later, I could add features for others to use on their more advanced (newer) devices without having to go out and buy each and every hardware variation. - - - So that's my feedback: please provide an emulator that runs on some host (a Debian Linux is fine) for which one can cross-compile and run the resulting binaries such that what you'll see on the emulator screen is what you'll see on the actual device. [Yes, inputs might be a bit different -- the pressure sensor is an interesting case -- but at least the stylus and hardware keyboard input should be possible.] Hope that helps!

Yes, this seems to be when the N800 switches to standby. It would be nice in x11vnc restarted automatically... But the big problem is the 'dead' area of the screen ...

VMWare appliance maemo and Samba
Very many thanks for setting up a VMWare appliance for maemo! This allowed me to compile and run the canonical 'Hello world' example in just a few hours -- I hadn't run Linux for a few years; it's good to be back :-). I'm running as a virtual machine on a Windows XP host, and I think the one think I need before being able to start a serious application port to the N800 is to be able to share files easily between the virtual machine and the XP host. I'm almost there, but not quite: I installed Samba using the synaptic package install, then used Share Folders to set a share for my home directory (and also set the workgroup name for my local network). All seemed to take, but: -- I cannot see any of the Windows machine (or myself) in the Windows Network on Ubuntu -- from the Windows side, I can see the machine UBUNTU-MAEMO (so I think Samba is running OK) -- but when I try and connect to the share the Password dialog just gets re-presented, as though the user and password are wrong.
