Ubuntu 16.04 (EE) xf86OpenConsole: Cannot open virtual console 2 (Permission denied)

fix.md

sudo apt-get install xserver-xorg-legacy

Edit /etc/X11/Xwrapper.config

allowed_users=anybody
needs_root_rights=yes

Thank you so much for this! Installing the v390 nvidia drivers for a GTX 1070Ti broke xorg for me

Thanks, worked for me. Didn't personally need to edit Xwrapper though.

Hi there,
this and "The system is running in lo graphics mode" screen is a problem I'm struggling with - since a long time ago.
The above documented and anything I found on the net (incl. Ubuntu forums) didn't work for me

The following is my solution

1.) From the "The system is running in lo graphics mode" screen exit to a console and login as root

2.) Remove unity, lightdm and ubuntu-desktop (with all the wrong configuration data)
$ apt-get remove unity lightdm ubuntu-desktop
$ dpkg --purge unity lightdm ubuntu-desktop

if dpkg is warning about configuration files or directories it cannot remove, remove those files/directories manually, e.g.:
$ rm -rf /etc/lightdm /var/lib/lightdm-data

3.) Newly install unity, lightdm and ubuntu-desktop
$ apt-get install unity lightdm ubuntu-desktop

After the following command, the lightdm login screen appears and all should work fine...
$ service lightdm start

I was unable to start xfce4 / lightdm on openmediavault 4 (based on debian stretch).
I was thinking to reinstall everything... but I won't need to because of your lifesaving fix. <3

on Debian*

dpkg-reconfigure xserver-xorg-legacy

select anybody as allowed users

thank you @alepez

Don't know why but surprised that the needs_root_rights=yes line is actually needed, but its true :P

I had this problem but bizarrely,it was caused by a couple of entries in /etc/fstab which pointed to NFS mounts that didn't exist. Even though the "noauto" was set, it still stopped me logging in to the desktop.

i confirm it too!

Thank you, you saved me after hour of googling

Right on the money. You are doing god's service.

Six years later running Void, I've ended up here too. For some reason 'needs_root_rights=auto' does not work. Xwrapper insists on 'yes'. Could not find the answer.

Many thanks!!!

Worked for me. Absolutely incredible this is not in the KlipperScreen docs.
