This happened for me on a regular kernel upgrade (to 3.13.0-16-generic on 14.04). After upgrading, the users could not start their desktop session, they would be immediately kicked back to the login screen.
Apt-get could not purge the existing fglrx installation, and dpkg could only remove the packages one at a time using the -f command as some of the library links were broken (apparently during the upgrade). My first clue was here in the output from # apt-get upgrade. Other packages installed fine, but the fglrx did not. It returned: Setting up fglrx-updates (2:15.201-0ubuntu0.14.04.1) ... update-alternatives: warning: forcing reinstallation of alternative /usr/lib/fglrx/ld.so.conf because link group x86_64-linux-gnu_gl_conf is broken update-alternatives: warning: forcing reinstallation of alternative /usr/lib/fglrx/ld.so.conf because link group x86_64-linux-gnu_gl_conf is broken I attempted to remove and reinstall the proprietary drivers using # apt-get remove --purge fglrx* But that resulted in the following: Purging configuration files for fglrx (2:15.200-0ubuntu1) ... update-rc.d: /etc/init.d/atieventsd exists during rc.d purge (use -f to force) dpkg: error processing package fglrx (--purge): subprocess installed post-removal script returned error exit status 1 Errors were encountered while processing: fglrx I was able to get things working following the instructions here: http://askubuntu.com/questions/268749/amd-driver-install- troubleshooting. That is, I installed the linux-source, removed the fglrx packages individually using dpkg. Once this was done I was able to reinstall. Dpkg -l listed both the fglrx and the fglrx-updates versions, even though the fglrx-updates packages were the ones being used. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to fglrx-installer in Ubuntu. https://bugs.launchpad.net/bugs/1229761 Title: package fglrx (not installed) failed to install/upgrade: subprocess installed post-removal script returned error exit status 1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/fglrx-installer/+bug/1229761/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
