Alessandro Viprati, thank you for reporting this and helping make Ubuntu better. However, your crash report is manually attached.
Please follow these instructions to have apport report a new bug about your crash that can be dealt with by the automatic retracer. First, execute at a terminal: cd /var/crash && sudo rm * ; sudo apt-get update && sudo apt-get -y dist-upgrade && sudo service apport start force_start=1 If you are running the Ubuntu Stable Release you might need to enable apport in /etc/default/apport and restart. Now reproduce the crash, then open a terminal, navigate to your /var/crash directory and file your report with: sudo ubuntu-bug /var/crash/_my_crash_report.crash where _my_crash_report.crash is the crash you would like to report. By default, this sends the crash to the Ubuntu Error Tracker infrastructure, which is different than Launchpad. For more on this, please see https://wiki.ubuntu.com/ErrorTracker . However, if after doing this you would still like to have a crash report posted to Launchpad, for example to ease triage and add others to your report, one would need to open the following file via a terminal: sudo nano /etc/apport/crashdb.conf and comment out the line: 'problem_types': ['Bug', 'Package'], by changing it to: # 'problem_types': ['Bug', 'Package'], Save, close, and file the crash report via: sudo ubuntu-bug /var/crash/FILENAME.crash Where FILENAME is the actual name of the file found in the folder. However, this report is being closed since the process outlined above will deal with this issue more efficiently. Also, please do not attach your crash report manually to this report and reopen it. Thank you for your help.

However, every time I try, the OS hangs and returns to the lightdm login screen.

DRI_PRIME=1 glxgears 5. then, the system hangs with a black screen and returns to the login screen I've tried with DRI_PRIME=1 supertuxkart/redeclipse/other 3D applications, but the result is always the same. I've also tried to install a different DE with different compositing window managers: XFCE+xfwm and XFCE+compton. However, if I try to use DRI_PRIME=1 the result is always the same. No problems when using DRI_PRIME=0 (mullins integrated graphics), therefore the initial configuration should be ok. It seems not related to compiz, but to something regarding the graphics stack (radeon? mesa?) As of now, I can't use my dedicated GPU.
