Sorry Chris, I couldnt get what you said. Actually i got the source code for version 4.1.2 for windows and unix. i didnt find randr.c file in this code which is there in patch file. Sorry for giving troubles as patching i will do first time. Thanks, Paresh

I believe the current release is 4.1.2 and the patch should work on that also. It's a diff file that contains the added coded needed to enable some randr support for xvnc. You have to get the source for the vnc server, apply the patch, run with the new binary and give the extra -geometry options to the new Xvnc binary at run time. Then you will have multiple server sizes available to you. So, download vnc4_4.1.1+X4.3.0.orig.tar.gz. 'cd' into vnc4_4.1.1+X4.3.0.orig. Copy the patch file into the current directory . Apply the patch with the "patch" command. Follow the build instructions to get your new Xvnc server. -Chris ________________________________ From: PARESH MASANI [mailto:[EMAIL PROTECTED] Sent: Thursday, April 03, 2008 11:13 AM To: Williams, Chris (Marlboro); vnc-list@realvnc.com; [EMAIL PROTECTED] Subject: Re: To resize the VNC session window size Chris, Thanks for your valuable reply. >>I have attached the file you need to enable resize support.

Paresh, VNC developers have decided not to officially include RandR support for an as yet unexplained reason. The current RandR protocol version is at 1.2. I have patched my VNC server to support *some* of RandR 1.1, including resize capability. I have attached the file you need to enable resize support. Thanks go out to Nikita Youshchenko at Debian for this patch. Let us know if you have any problems implementing this patch. The rate at which this issue is raised, even on this one list, and the nearly non-existent response it gets from developers is alarming. -Chris -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Adam Tkac Sent: Thursday, April 03, 2008 4:35 AM To: PARESH MASANI Cc: vnc-list@realvnc.com; [EMAIL PROTECTED] Subject: Re: To resize the VNC session window size On Thu, Apr 03, 2008 at 01:32:59PM +0530, PARESH MASANI wrote: > Hi, > > I created a VNC session using vncserver with resolution 3200x1200.

Server has to support RandR extension but it is not developed yet (something exists on http://www.freesoft.org/software/vncrotation/ but I never tested it). You have to stop that session and start it again with new resolution.
