I have two monitors; the second one sometimes comes to life but is usually blank. However, the system thinks that it is active and displaying.
The primary monitor is a Samsung 24" and the secondary (usually non- functioning) one a Mirai - Chi Mei Optoelectronics 22". Just occasionally the second monitor comes up and can be used normally, but once the displays are turned off by the screen saver, it remains blank when the display comes back. However the "Displays" utility says that it is in use. Previously I avoided the problem by turning off the screen-savers and leaving the monitors turned on 24 hours a day, but I have just installed Debian (instead of Mint) and the problem has come back. Any ideas where to start to solve this, please? -- Oliver Elphick Lincolnshire, England
