I have installed many desktop environments, but my default Ubuntu session isn't working. I can only login using Ubuntu with Wayland. I want to login with the other options which are shown below. I tried to install an AMD graphics driver on my laptop and lost all of them except for Ubuntu with Wayland.

The default Ubuntu session was working. I've been using this Ubuntu installation since 2011, and always upgraded to the next LTS release when it came out. I purchased a Dell Inspiron 5570 that has AMD Radeon 530 discrete graphics and replaced my hard drive. I have upgraded 16.04 to 18.04 on my Dell Inspiron 5570. The problem began after I have tried to install an AMD driver. I haven't had a single serious problem in last 8 years, but now just one AMD graphics driver is creating a lot of trouble.

Results of lspci -nn | grep -E 'VGA|Display' :

  • before installing new Desktop Environments, has the default Ubuntu session worked? or since Default Session is not working you installed different Environments? – PRATAP Jan 01 '19 at 12:02

Only the Wayland login option works since installing the amdgpu-pro-18.20-673703-ubuntu-18.04.tar.xz (proprietary AMDGPU-PRO) graphics driver, so uninstall the proprietary AMDGPU-PRO graphics driver and reboot the laptop.

The following command will provide you with the version of the AMDGPU-Pro stack on your system, or inform you that there are no packages found:

dpkg -l amdgpu-pro

ubuntu-drivers list will show which graphics driver is installed. Open the terminal and type:

ubuntu-drivers list

After you uninstall the non-working AMDGPU-PRO graphics driver, you can run this command to see what graphics driver Ubuntu 18.04 recommends for your Dell Inspiron 5570, if any. 

ubuntu-drivers devices

If ubuntu-drivers devices doesn't recommend installing anything, then don't install anything.

Reinstall Xorg (xserver-xorg).

sudo dpkg --remove --force-remove-reinstreq xserver-xorg  
sudo reboot

It's not necessary to reconfigure Xorg. Click the gear icon at login and choose a Xorg session. After that the laptop will always boot to Xorg until you click the gear icon at login again and choose a Wayland session.

  • There is not any AMD Driver. – user2077875 Jan 01 '19 at 13:06
  • "ubuntu-drivers list" and "ubuntu-drivers devices" do not show any output. – user2077875 Jan 01 '19 at 13:15
  • I have downloaded it from AMD Website. amdgpu-pro-18.20-673703-ubuntu-18.04.tar.xz – user2077875 Jan 01 '19 at 13:18
  • sudo: amdgpu-pro-uninstall: command not found – user2077875 Jan 01 '19 at 13:28
  • I am in search of some way to reinstall or reconfigure that Xorg? I am feeling X better than Wayland because sometimes I have more than 10 ssh screens at once. If there is some way to reconfigure or reinstall Xorg. I am not feeling comfortable with this Wayland. I have lot of sticky notes, logs, manuals at my screen, and, everything is disturbed now. According to my experience, the problem is with Xorg, not with ubuntu Desktop environment itself. – user2077875 Jan 01 '19 at 13:43

  • The problem is that Xorg session is not loading. – user2077875 Jan 01 '19 at 13:49
