G'day All As an update, I have also tried x11vnc using a variety of settings (-xinerama -noxwarppointer -noshm -noxdamage -noxfixes to name a few) without any luck.
I have tried recompiling, re-installing and re-starting vino, as suggest http://bugzilla.gnome.org/show_bug.cgi?id=346258 I have also tried and number of xorg.conf settings. The interesting kicker is that similar problems occur when using synergy... IE, can only control one of the screens. I am now tending to think that the issue is more of an nvidia driver issue or an xorg issue. I initially submitted a bug report to the gnome forums, see http://bugzilla.gnome.org/show_bug.cgi?id=570178, but with suspecting the nvidia driver, I have submitted a nvidia forum post, see http://www.nvnews.net/vbulletin/showthread.php?t=127386 Thanks for everyone's comments so far and I will keep you all posted.

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). 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. 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. I am using 2 nVidia Quadro FX1700 video cards, using nvidia-setting to configure the 4 displays using xinerama. Note: 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. 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). 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. Someone mentioned that there might be a -ignorexinerama option within the server or vncviewer, but I haven't been able to find anything. Details on the system are as follows: Dell Precision T3400 2.4GHz quad-core Core 2 (Q6600) Dual 512MB PCIe x16 nVidia Quadro FX1700 video cards 2GB of Memory 320GB SATA HDD (3.0Gb/s, 7.2k RPM) Gigabit NIC 16X max DVD+/-RW Drive Running Fedora 10 (x86_64 Version) Your assistance in helping me to solve this problem would be extremely appreciated.
