It worked again, don't know exactly why but this is what I did: I removed all the themes that gdmsetup let me remove, i think the only ones left was Circles and the Happy GNOME themes, then reinstalled the gdm, gdm-themes, ubuntu-desktop, ubuntu-themes and things like that, at this point i have not fixed anything, it was worse because the Human theme never appeared again so I got an error reporting that cannot open or read /usr/share/gdm/themes/Human/Human.xml file, of course there was no Human directory in /usr/share/gdm/themes, then I made a copy of a theme directory, Crystal in this case, and renamed the directory to Human, and it loads as the default theme, don't know why because I removed any reference to the Human theme in the .conf files, by the way, the gdm.conf-custom was empty, 0 bytes and I replaced it with the gdm.conf file and nothing different happened, but that was before I replaced the Human theme directory, after that I'd go to the gdm screen using the Switch-User option, and loaded Crystal, I logged again and deleted the Human directory, again, somehow when I enter the gdmsetup it was working again as it should, selecting and saving the theme as usual, I believe I did extra work because probably all the problem was that the gdm.conf-custom file was truncated to zero, maybe just replacing that with the gdm.conf file or factory-gdm.conf would have been enough to solve the problem.
If anybody can check and see if just replacing the truncated gdm.conf- custom file fix the problem, I would like to know, now everything works fine, maybe the error is where the file was truncated to zero. -- [gutsy] gdm (including gdmsetup) ignores or cannot access gdm.conf-custom https://bugs.launchpad.net/bugs/195296 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gdm in ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
