Try purging the gdm2 configuration tool via sudo apt-get purge packagename or, if it doesn't work sudo dpkg -P packagename If you installed it from the repos or a .deb package, it should remove it. Then do a sudo apt-get --purge autoremove and sudo apt-get clean which will remove all packages that have been downloaded from apt (the apt package cache) and, finally execute sudo apt-get --reinstall install gdm If the problem was the gdm2 manager it should be gone. in EVERY step of this procedure, particularly at the autoremove, pay attention to the packages that are removed. if you notice some programs and/or libraries you think must stay there, or see a huge list of packages that are going to be removed, abort; your system shouldn't be affected, if you do so.
