Comment 9 for bug 515933

Easiest way would be to add the xorg-edgers lucid PPA to your sources, install ppa-purge, then sudo ppa-purge xorg-edgers to go back to stock lucid. the lucid packages are all higher version numbers than the karmic ones and are built correctly for lucid so you can just use that if you want to. Alternatively, remove xorg-edgers from your sources, sudo apt-get update and then for every package listed there add it to this -

sudo apt-get install libdrm-intel1/lucid libdrm2/lucid ..etc

adding /lucid to the end of the package name like that. You might want to dpkg -l | grep sarvatt and dpkg -l | grep tormod just to be sure you got everything if you do it that way.
