Okay, I've just (~21:13 UTC) installed kernel "4.4-rc2+cod1". Packages installed:

In english, the message translates to "There was a problem while attempting to start Catalyst Control Center Linux Edition. It may have been caused by the following: No AMD graphics driver installed, or AMD graphics driver not working properly. Install the proper AMD driver to your AMD hardware, or configure it with 'aticonfig'." Well, this pretty much confirms to me that "fglrx_updates" is definitely a proprietary AMD GPU driver and thus doesn't work with these kernels, as explained in https://wiki.ubuntu.com/Kernel/MainlineBuilds I will keep this kernel running for the next hours and report back if any message like "[drm:gen8_irq_handler [i915]] *ERROR* The master control interrupt lied (SDE)!" comes up in "dmesg". -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1520040 Title: [drm:gen8_irq_handler [i915_bpo]] *ERROR* The master control interrupt lied (SDE)!
