I've had Xubuntu on my home desktop for years, using 15.10. I have full-disk encryption, so that's the first prompt, and that always unlocks successfully.
Since some recent upgrades (I can't identify what), whenever I get to the actual login screen, it displays for about half a second and then goes blank. If I leave it for 5-10 mins, and then come back and move the mouse, it clears and displays the login screen correctly, and I can log in and all is OK. In fact, even when it goes blank, the password box has the focus, so I can actually type my password blind and log in and everything comes back on and works. Rather than report a bug on an outdated system, I decided it was time to upgrade to 16.04. I usually run Enlightenment, which doesn't monitor system versions or settings, so this time I booted into xfce. I started update-manager from the command line, which invited me to upgrade to *Kubuntu*! I'm not sure why it did this, as I don't know the criteria it uses to judge what distro you're running, and I have never in my life installed Kubuntu, although I do have a few items of KDE-originated software installed. No matter, Ubuntu is Ubuntu, so I went ahead, and everything installed without apparent error. K asked me for the disk password, and that went OK, but now the screen goes blank and stays blank except for a *tiny* cursor in the top left-hand corner. I can use Ctl Alt F1 and get a terminal job, and log in and run startx, and KDE comes up OK (which is how I'm writing this). So it seems the system is just fine: only the login screen never appears. 1. Is this a known bug (ie do I need to log it)? 2. How do I change the default session interface from KDE to another installed one (eg xfce or Enlightenment) *from the command line* (seeing as I have no access to the login screen where the drop-down session indicator is)? ///Peter -- xubuntu-users mailing list [email protected] Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/xubuntu-users
