When I emerged the latest; GDM was upgraded to 2.6. There was no where in the ebuild saying that GDM looks for sessions in a different directory. This causing the KDE session(s) not to be listed. After going through the gentoo forum; I found the proper solution. Could someone update the ebuild to either reflect that by stating it or simply copy the required data into the new directory.

Unfortunately just copying files wont work. The file format is also totally different no. However I think of the following solution (need to try it though). At the moment when gdm is emerged it will create a .desktop file for every old session, this file will effectively call the old script. That's just an idea and I need to try it. Gnome people - what do you think?
there is no gdm 2.6 at this point in the tree, so that part of the bug is invalid. I think WM's should just add their respective new-style session files as needed. They have had plenty of time to do so, so i don't want to go into strange hacks. *** This bug has been marked as a duplicate of 40711 ***
