I ran into the same problem when I tried to switch to proprietary graphics driver from settings. By default x server was in charge. Provided that you got a similar issue here, you can try to uninstall the driver. In my case, I had Nvidia, so I went to tty1 by CTL+ALT+F1, then login/password and use purge to uninstall: $ sudo apt-get purge nvidia* $ ...

I have the same problem with a clean 16.04 install. Added my comments on the launchpad bug report. I'm guessing the fix, or a workaround, might be something as simple as... sudo chmod 777 ???? I just don't know which permissions to change.

I have the same problem. Running Ubuntu 16.04. Intel HD4600 and Nvidia 765M. Tried all the suggestions above. It worked when installing using terminal, but if I use multiple monitors it bugs out and I end up in a boot loop. I've read someone suggesting that the beta driver 364xx works.

I'd tried the common suggestions: gsettings, dconf, modprobe, none of which solved it for me running Lubuntu 15.04 and Lubuntu 16.04. What worked was removing the silent splash option from grub. (Easy way to do this is by installing Grub Customizer). The aforementioned solutions may have contributed to solving the issue, but I found removing silent ...

Sound support was disabled in the BIOS of the machine for me. Hence, no driver worked. This happened because I loaded the failsafe settings in the bios while trying to get the machine to boot via floppy, CD and USB. However, once I loaded the optimized defaults in the BIOS settings, everything worked fine.

Unity-2d is not supported anymore since Ubuntu 12.04 So I doubt that you can install it on 14.04.... You will need to install another desktop such as mate-desktop,lxqt,lxde,kde,xfce... with Ubuntu 1604, you can use mutiny and configure the desktop to look like unity (look alike but not the same) Check this post Hope this help

I had a very similar problem with NVIDIA install script. I've booted into recovery mode (hold SHIFT before loading GRUB for a menu) and there was an option to open a root terminal. Try those commands, reboot and see if it will fix your case: dpkg-reconfigure xserver-xorg update-initramfs -u You might need to remount with write priviledges to make ...

Two thoughts: For low level logins, like you're doing, frequently the ENTER key must be pressed to get a login prompt. Just because the graphics are crazy, doesn't mean that the daemons like sshd didn't come up properly.

Have you checked /var/log/Xorg.0.log for errors? Or when you stop X, try startx rather than restarting the service.

~/.xinitrc did not work for me on Ubuntu 14.04 but the following in ~/.profile did. On each login, GUI/terminal/SSH/etc..., the script will run so I redirect stdout to silence the output. xhost +local: > /dev/null
