System unbootable after fglrx installation

[Eloy Vallina]

After coming across with this info https://bugs.launchpad.net/ubuntu/+source/fglrx-installer/+bug/1424491 in which the installation of fglrx seems fixed in trusty I attempted the following:

Installation of fglrx drivers for my Radeon M260 in my laptop with Ubuntu Gnome 14.04.3 LTS

$ sudo apt-get install fglrx-updates xvba-va-driver
.
.
.
Installation finished with no errors or warnings

$ sudo reboot

After Gnome loading screen (before log in) boot stops with following messages in intermitten screen followed by "[OK]" at the end of each line:

* Starting atieventsd [OK]
saned disabled; edit /etc/default/saned
* Starting network connection manager
* Restoring resolver state
* Starting crash report submission daemon
* Stopping System V runlevel compatibility

After reboot, same info displayed plus:

* Stopping cold plug devices
* Stopping log initial device creation
* Starting save vdev log and update rules
* Stopping save vdev log and update rules

After new reboot this long message:

* Starting automatic crash report generation
* Starting ACPI daemon
* Starting configure virtual network devices
* Stopping restore sound card state
* Stopping anac(h)ronistic cron
* Starting cups-browsed -- Bonjour remote printer *illegible in my notes* daemon
* Stopping save kernel messages
* Starting regular background program processing daemon
* speech-dispatcher disabled; edit /etc/default/speech-dispatcher
* Starting network connection manager
* Starting atieventsd
saned disabled; edit /etc/default/saned
                              * Restoring resolver state

After fourth reboot the first message repeated

I managed to boot into text mode editing grub's ubuntu entry and attempted:

$ sudo apt-get remove fglrx-updates
.
.
apt-get will INSTALL fglrx-core
.
.
Removal and installations finish with no errors or warnings

$ sudo reboot

Same problem

Back into text session

$ sudo startx

Can't boot into gui mode: xinit connection to xorg lost (or something similar)

$ sudo apt-get remove fglrx-core
.
.
apt-get will INSTALL fglrx-updates (At this point I'll admit I cried a bit)
.
.
NO!
Abort

$ sudo apt-get purge fglrx*
.
.
.
.
Big removal completed

$ sudo startx

Finally able to boot into gui
