I've updated > the fault report version number to 19.12.3. Another update. I'm using the on-board i915 graphics. Testing on another machine with the same chipset, but running Mint Tina, showed no problem. The problem system has both on-board i915 plus an nvidia card. I blacklisted the nvidia driver and rebooted. This time both 18.x and 19.x crash spectacularly and dump core. Removing the nvidia blacklist entry, but switching to the nouveau (nv) X11 driver works, albeit 19.x is a bit slow. The monitor display is fine - no flickering. It looks as though the mere presence of the nvidia driver causes the flickering issue. And even though I'm using the i915 graphics, something to do with the nvidia hardware is affecting things. This is now well beyond my knowledge. -- You are receiving this mail because: You are watching all bug changes.
