For my gdm 2.20 to 2.26 upgrade I'm not sure - my experience was that I was taken from my X session to a new-style gdm, and on logging in, back to my previous X session.
For my gdm 2.26.1-0ubuntu1 to -0ubuntu2 upgrade, it definitely killed my session outright. -- gdm 2.26 kills or switches away from active X sessions on upgrading https://bugs.launchpad.net/bugs/395313 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
