[Qemu-devel] VNC Patch - solved

[Lindsay Mathieson]

Note : I've changed my list email from lindsay.mathieson@optusnet.com.au 
to lindsay@softlog.com.au

Ok, my problems with the vnc patch were that it could'nt find the 
keyboard maps for vnc. I had to hardcode the location into the source, 
it seemed to assume a relative path, but I guess this is something I 
should take up with the vnc patch creator.

You on this list Johannes ? I'd love to test and help if you want to 
pursue this.

Note that the VNC patch is experimental. Unfortunately I did not yet have
the time to investigate the problem with Win98's standard mouse
acceleration. When I get this to work reliably, I call this patch finished
and try to fix up things like keymaps and also SDL or X using those
keymaps (for non-PC architectures).

Yes, I am on the list. Even if I sometimes have strange problems: You sent
this email to me as well as the list, but I got it only once. Probably I
don't get all mails which are sent to the list. Some emails have delays of
more than one day.

And yes, I want to make it work, but my first priority right now is my
work, and then the Win98 mouse.

[Qemu-devel] VNC Patch - 6th version

[Johannes Schindelin]

Hi all,

I am proudly announcing a new incarnation of the VNC patch. Not much new,
really:
	- applies to current CVS version
	- fixes the mouse calibration with Windows 98

Unfortunately, for some systems (e.g. Windows 98), you have to calibrate
the mouse. For that, you have to move (somehow) the mouse pointer to an
empty spot on the desktop (with space above it), and then press and
release Ctrl+Shift. Your mouse cursor should go a little bit upwards and
then jump back. After that, the mouse pointer movements should be
consistent with the host pointer.

You can find the patch at
http://libvncserver.sourceforge.net/qemu/

Ciao,
Dscho

Just building it now. Before I applied the patch I had to rename my 
"qemu" dir (clean cvs co) to "qemu_cvs" before the patch would apply

Got it running:
- still have to manually  edit keyboard_rdesktop.c and hardcode the 
prefix path for keycode to load
- the mouse does seem to track now, though it is extremely jerky and erratic

The session keeps disconnecting, it seems to make a difference choosing 
different compression ratios, also screen res in the guest makes a real 
difference as well.

e.g connecting with UltraVNC on AutoSpeed selection to win98 at 800x600, 
the client disconnects immediately.

The patch assumes that you start qemu from the qemu directory. By the way,
you don't have to rename the qemu directory to qemu_vnc or qemu_cvs, but
you can "cd qemu; patch -p1 < qemu-rfb6.patch".

Yes. I don't know yet why it is jerky, but I found it more important that
it is sort of accurate first.

this probably means a bug in LibVNCServer. Hopefully I find the time to
look into that.

Thats exactly what I did, didn't work. Had to rename qemu to qemu_cvs 
first.That patch I decompressed had qemu_cvs in it.

That it does seem to be. Its probably worth mentioning that using qemu via 
remote xwindows/sdl is equally jerky. Hwoever the vnc client (when connected) 
is much better looking.

I use utltra vnc for a client usually, but tight vnc has the same problems. 
Both clients are under windows. The host os is Mandrake 10
