--- Comment #29 from Fabio Coatti <fabio.coa...@gmail.com> --- I have the same issue, with an HP and a dell external monitor. (1366x768 vs 1920 x 1200). In my case, physically disconnecting the monitor or simply turning it off fixes the external monitor "blanking" -- You are receiving this mail because: You are watching all bug changes.
