Black screen after system updates

[NickElliott]

Kubuntu 17.10 amd64

After recent system updates on reboot I get a black screen after the login screen, no desktop.

Various attempts to start plasma desktop/kde failed with messages such as:
ksmserver closed unexpectedly
display is not set or cannot connect to the x server

The following packages had been updated to v 17.2.8:

libgbm1
libegl1-mesa
libwayland-egl1-mesa
libglapi-mesa
libgles2-mesa
libgl1-mesa-glx
libgl1-mesa-dri
libxatracker2
mesa-va-drivers
mesa-vdpau-drivers

I reinstalled the previous version of these drivers and everything was back to normal.

I read elsewhere someone reporting a similar problem but that it had gone away after recent updates. So I reapplied the above system updates and again had no desktop after rebooting.

I again reverted to the previous versions (17.2.2) and the desktop is now working again.

My graphics card is AMD/ATI Radeon
