Hi folks, I upgraded about a month or two ago from Ubuntu 13.04 to 13.10. I run an Nvidia card with the binary drivers (tried both the release and the -updates version). I have two displays, one 1920x1200 and one 1280x1024. I don't use Unity - to me it makes sense possibly for touch devices, but as I prefer using a keyboard and mouse, it's not for me... so I'm currently running gnome-panel etc. My card's: 01:00.0 VGA compatible controller: NVIDIA Corporation G92 [GeForce GTS 250] (rev a2) I've found that after rebooting, sometimes after updates, user switching no longer works. I've found running this: sudo /usr/lib/lightdm/lightdm-set-defaults --show-manual-login true as documented here: http://askubuntu.com/questions/379485/problem-changing-users-in-ubuntu-13-10 ... seems to fix user switching, but I still keep getting xorg crashes ("An error has occurred in your system" or similar dialogs). Submitting reports comes up with nothing. Also, lightdm thinks my left display is my right display, and my right my left - yet once logged in as a user, all's right with the world? Am I right in thinking that Ubuntu have deliberately broken something to do with gnome and are trying to push me towards Unity? ... or do I need to blow away some config files somewhere and reset things to default? Thinking perhaps of switching to LXDE and/or back to Debian. Anthony
