When you connect to running X server with a libvnc.so from the current stable tigervnc loaded (net-misc/tigervnc-1.0.1_p20100529), the first mouse movemount cause the X server to crash. Reproducible: Always Steps to Reproduce: 1.emerge tigervnc with +xorgmodule in USE 2.Load "vnc" and configure it in /etc/X11/xorg.conf 3.Start the X server 4.Connect to it with vncviewer Actual Results: The X server crashes with these messages on the first mouse movement: VNCSConnST: Server default pixel format depth 24 (32bpp) little-endian rgb888 VNCSConnST: Client pixel format depth 24 (32bpp) little-endian rgb888 /usr/bin/X: symbol lookup error: /usr/lib64/xorg/modules/extensions/libvnc.so: undefined symbol: AllocDevicePair kded4: Fatal IO error: client killed ...

Expected Results: It should behave correctly as it did prior to the last xorg-server/tigervnc bump. There appears to be version skew between xorg-server and tigervnc in portage - see this link for a patch which restores the correct behavior: "dix: Export AllocDevicePair GetPointerEvents, GetKeyboardEvents and generate_modkeymap functions from Xorg" http://cgit.freedesktop.org/xorg/xserver/patch/?id=2f29b163bbdebe384c24f781bb97b446959e8f4c Taking the above patch and creating an updated ebuild with this one line patch is sufficient to correct the problem: --- xorg-server-1.7.7-r1.ebuild 2010-08-11 23:22:48.000000000 +0100 +++ xorg-server-1.7.7-r2.ebuild 2010-08-28 15:34:51.579465591 +0100 @@ -131,6 +131,7 @@ PATCHES=( "${UPSTREAMED_PATCHES[@]}" + "${FILESDIR}"/export-AllocDevicePair-etc.patch ) pkg_setup() {

Hum, this changes the server API, I'm not sure it's safe to do this now. 1.9 is fixed however, and that we're targeting for our next stabilization. I suggest you keep a patched copy of 1.7 for now. Thanks
