Timo: I don't know exactly for the 14.04.3 LTS -utopic to -vivid HWE upgrade, but I can confirm this bug is still present for the 14.04.3 LTS -trusty to -vivid HWE upgrade.
I've just done a fresh install of 14.04.x LTS, using a PXE server so I'm not exactly sure what the x was in the image I used. On completion of the install and updates I was left with a 14.04.3 LTS and the original kernel and X server, i.e. linux-generic and xserver-xorg. I updated them to linux-generic-lts-vivid and xserver-xorg-lts-vivid. After purging the old xserver-xorg related packages, the /etc/X11/X link was gone. I still believe this bug should not be left unfixed, but perhaps that's just me. ** Summary changed: - Xorg fails to start after installing the hardware enablement stack on precise due to missing symlink after purging old xserver-xorg + Xorg fails to start after installing the Hardware Enablement Stack due to missing symlink after purging old xserver-xorg -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1132736 Title: Xorg fails to start after installing the Hardware Enablement Stack due to missing symlink after purging old xserver-xorg Status in xorg package in Ubuntu: Triaged Status in xorg-lts-trusty package in Ubuntu: Confirmed Status in xorg-lts-utopic package in Ubuntu: Confirmed Status in xorg-lts-vivid package in Ubuntu: Confirmed Bug description: Bug: The bug happens whenever the remaining configuration files of the original X stack is removed, ie purging. It does not happen for users who do not explicitly remove those. Workaround: For example, if upgraded 14.04 LTS to the 14.04.2 HWE stack (=14.10/utopic): sudo dpkg-reconfigure xserver-xorg-lts-utopic This restores the symlink /etc/X11/X -> /usr/bin/Xorg --- After installing the hardware enablement stack on precise by running: sudo apt-get install linux-generic-lts-quantal xserver-xorg-lts-quantal Xorg fail to start. There is no error message or anything, just a black screen. Switching to a vt i possible and lightdm/x-0.log shows that a symlink is missing: X: cannot stat /etc/X11/X (No such file or directory), aborting. I updates two computers running precise x86_64 and both had the problem. Just recreating the symlink fixes the problem and then precise runs perfectly fine with the new stack (in fact, it's more stable so far).
