After updating to Ubuntu 15.10, I've been hit with problem after problem. However, this most recent one has to be the worst yet.

Upon startup, my computer runs in low-graphics mode. Attempting to run in default settings kicks me to a tty. Viewing the xorg log tells me that lightdm is generating a broken xorg.conf, so the first thing I do is open a tty and type sudo nvidia-xconfig. Restarting lightdm just regenerates the broken config, so I don't bother with that. But when I try to run sudo startx, it blackscreens, which I expect, but then kicks me back to the tty, which shows no error message, just waiting for X server to shut down (II) Server terminated successfully (0). Closing log file. From there, the system hangs, and I can't type in anything; the only button that actually does something is the power button.

I have a GeForce 745m card, on an Asus Q550L laptop.

I've tried following this this thread, even mixing and matching solutions to no avail: How to solve black screen problem after installing nvidia drivers on Ubuntu 15.10?

Any ideas?

(edit) I've updated my kernel to 4.3.0, based on a different error I was getting previously. After purging and reinstalling nvidia-355, I noticed that dkms was telling me that this kernel is not supported. I would assume this is linked, but it was a solution to another, similar problem, so I don't know what I should do with it...

...And now nvidia-xconfig is gone, so I can't even use that to regenerate xorg.conf properly. I'm going to attempt installing nvidia-current over nvidia-355, then reinstall the latter. That should bring back nvidia-xconfig. (EDIT: It did.)

Do you have the same issue if you remove the nvidia drivers and use the Nouveau drivers instead?

Here is what worked for me: Start a root sheel (select advanced Ubuntu)

mount -o remount,rw /

apt-get purge nvidia*

reboot

sudo apt-get purge xorg lightdm

Autoremove whatever left

sudo apt-get autoremove

Install lightdm and xorg

sudo apt-get install xorg lightdm

  • For some reason, my computer won't allow me to get to the GRUB menu. I'll try those (except for the first, of course) in a tty using sudo. Nov 9, 2015 at 16:12
  • No dice. Reinstalling the nvidia drivers. Nov 9, 2015 at 16:30
