Comment 9 for bug 402260

Althoug this is fixed upstream and in latest Lucid packages, it still does affect karmic. xdmx under karmic is completely unusable due to this bug (and some others, which can't be seen due to xdmx not starting...). I have a set of patches ready, handpicked from upstream xorg git, which make xdmx on karmic usable again. Based on these patches, I made a ppa which builds xdmx and xdmx-tools from karmics patched xorg-server source package. It can be found at https://launchpad.net/~rdoering/+archive/xdmx-fix. If this bug affects you, please try packages from this PPA and report back if the problem is fixed.

I will add the individual patches here one after the other with a short description. Fortunately, xorg-server package uses quilt, so they may be integrated easily.
