@Alberto: I did not understand your last suggestion. I had not installed the xubuntu-default-settings, so when I tried to remove that, I got an error message. I had previously tried removing the XFCE4 and XFCE4-goodies metapackages, then reinstalling them, but that didn't help.
I ended up reloading my original Lubuntu-13.10 Saucy installation from backup, then installed, in this order nvidia-319 nvidia-settings-319 rebooted nvidia-prime from the Saucy proposed repository via Synaptic (updated grub) rebooted xfce4 xfce4-goodies* rebooted logged into xfce session chose Use default configuration It worked. No error messages loading the xfce desktop. Now I can use either lubuntu sessions or xfce4 sessions, and nvidia-prime seems to be working (at least going by glxspheres64). I'm not sure why it worked this time - I was 100% sure it would fail. But it worked. (*I had tried the sudo update-alternatives --config lightdm-gtk-greeter- config-derivatives, but I didn't understand what you meant by that command exactly. I got an error message saying no alternatives available.) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1224098 Title: xserver wont start after nvidia-prime installation To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-prime/+bug/1224098/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
