<P DIR=LTR><SPAN LANG="en-au"></SPAN></P>
<P DIR=LTR><SPAN LANG="en-au"></SPAN><SPAN LANG="en-au"><FONT FACE="Consolas">G’day All</FONT></SPAN></P>
<P DIR=LTR><SPAN LANG="en-au"><FONT FACE="Consolas">I was hoping that someone might be able to help me out with a problem.</FONT></SPAN></P>
<P DIR=LTR><SPAN LANG="en-au"><FONT FACE="Consolas">I have a Access Grid machine (details to follow) that has 2 x dual head video cards. I recently upgraded the machine to fedora 10 (No distro flame wars please) in which I can no longer remote desktop (using vnc) properly to be able to see and control all X Screens (4 in total).</FONT></SPAN></P>
<P DIR=LTR><SPAN LANG="en-au"><FONT FACE="Consolas">In previous versions of Linux, I use to use "Desktop Sharing" in KDE, but Krfb recently due to some software updates, has been found to be problematic.</FONT></SPAN></P>
<P DIR=LTR><SPAN LANG="en-au"><FONT FACE="Consolas">I am currently trying to use "Remote Desktop (Gnome)" in which appears to work fine, but only allows me to control the primary display screen. I have also tried x0vncserver with similar results.</FONT></SPAN></P>
<P DIR=LTR><SPAN LANG="en-au"><FONT FACE="Consolas">I am using 2 nVidia Quadro FX1700 video cards, using nvidia-setting to configure the 4 displays using xinerama. </FONT></SPAN><SPAN LANG="en-au"><B> <FONT FACE="Consolas">Note:</FONT></B></SPAN><SPAN LANG="en-au"><FONT FACE="Consolas"> if I use Separate Screens, I can only control the first screen, if I use Twinview, I am able to control the first 2 screens, but not the other 2.</FONT></SPAN></P>
<P DIR=LTR><SPAN LANG="en-au"><FONT FACE="Consolas">Also note that I need to be able to connect to this "desktop" via a windows machine, using something like realvnc or ultravnc (I have tried both).</FONT></SPAN></P>
<P DIR=LTR><SPAN LANG="en-au"><FONT FACE="Consolas">Therefore, I was wondering if anyone knew a solution to this problem as google doesn't seem to be helping me this time round. Though it does appear to be less an "distro" problem, as I have seen people (on the web) complaining about similar problems with other flavours of Linux.</FONT></SPAN></P>
<P DIR=LTR><SPAN LANG="en-au"><FONT FACE="Consolas">Someone mentioned that there might be a -ignorexinerama option within the server or vncviewer, but I haven't been able to find anything.</FONT></SPAN></P>
