Re: [Qemu-devel] vnc patch

[Christian Bourque]

Eric, is it possible to tweak something to fix the mouse issue?
Because under w2k my mouse is completely out of sync...

I tried disabling mouse acceleration like I read on the list but that
didn't help...

Thanks

Christian

   CVS has a usb tablet mouse that features absolute coordinate 
support.  This will eliminate the acceleration problem for guests with 
support.  Search the mailing list for more information.

   There is another vnc patch by Anthony Liguori (same person involved 
with the tablet along with others).  From what I've heard it will reduce 
the bandwidth usage greatly.

   Also, afaik this is still under development.  The source was posted 
on the irc channel a few days ago:

The mercurial tree is located at http://hg.codemonkey.ws/qemu-vnc  If 
you go to Manifest -> Changeset you can download a static tarball if 
you're unfamiliar with mercurial.

It's in a pretty good state now.  I don't think there's any significant 
bugs and all the features I plan on implementing for the first rev are 
there.  I'll have a patch ready for submission in a day or so.

Regards,

Anthony Liguori

Re: [Qemu-devel] vnc patch

[Christian MICHON]

did I understand well ?

1) there's a rework of the original vnc patch
2) there are no problems of sync using the usb tablet

what is this usb tablet stuff? do I really need a usb
tablet connected to the host or this is yet another
emulated hardware inside the qem guest ?

If this is the case, it means the client OS must
have the proper drivers, etc... I'm a bit lost.

Re: [Qemu-devel] vnc patch

[Troy Benjegerdes]

-usbdevice tablet emulates a absolute position USB HID device instead of
a PS/2 mouse, so there is no need for messy mouse calibration when using
VNC. It also allows you to get rid of the need to have the SDL version
'grab' the mouse.

I have a re-worked patch based on
http://libvncserver.sourceforge.net/qemu/qemu-rfb13.patch.gz that I
keep here. It applies cleanly against the april26th CVS snapshot and
works OK for me.

Hi!

Could someone post the last version of the vnc patch that applies
cleanly against current cvs version?

Thanks

[Qemu-devel] VNC patch

[ecs user]

I would like to use QEMU as a virtual server to a
couple of other machines on the network.

Does anyone know and can help me find information on
the VNC patch for QEMU?

It does this very well in fact.
I did manage to get it working with recent CVS to a point, but something went quite wrong with the 
key map handling and I ended up not being able to enter uppercase characters. I ran out of time.
I might see if I can have another crack at it on the weekend.

[Qemu-devel] VNC patch

[Piotr R.]

Hello,

I am working witch qemu rfb9 patch and I found it useful to specify 
local port on wchich vnc server would listen. Here is a patch for 
that. 

Does anyone have a solution for mouse/vnc problems (calibration etc.
)??

Apply it after rfb9 patch.
