Bug Description

Hi,

I am currently running in a severe problem with ubuntu's Xorg-Server, which might affect virtually all servers.

I yesterday installed a new machine with Lubuntu 16.04.2. Worked perfectly out of the box.

I then did an apt ugrade, and since then the X11-server completely ignored mouse and keyboard, was not usable (except from that machine was in good health).

I found the solution here:

https://askubuntu.com/questions/891670/how-to-fix-input-devices-after-xserver-xorg-core-upgrade

It just took a

apt install xserver-xorg-hwe-16.04 xserver-xorg-input-all-hwe-16.04
/etc/init.d/lightdm restart

to fix the problem.

But then, today, after another apt upgrade, the problem occured again, and I have to apply the fix again. The packages install yesterday seem to have been thrown out by some conflict between xorg packages.

It's a severe problem, if a simple apt upgrade renders the machine unusable, the average user might not be able to fix that or even login into the machine anymore.

Obviously there is a dependency-problem, which causes severe trouble. I am currently too busy to investigate this any deeper, but it really breaks the system for average users.

regards

I've found the problem.

It's the package xpra, which I do install through puppet, which conflicts with important Xorg packages and throws them out, thus making the Xorg server stop working properly.
