I have a Lenovo W510 with Mageia 4. Using the system settings tool, I can have two active displays at one time, even though the utility shows a third display in "ghost" form.
Here are two working scenarios:
1. Laptop display and external display via vga port.
2. Laptop display and external display via Display port, using either a Display Port to HDMI adapter or a Display Port to DVI adaptor.
What I would like to do is have three active displays:
1. Laptop screen
2. External screen attached to Display Port
3. External screen attached to the standard VGA port.
If I try to activate the third display, nothing happens, even though the system settings tool shows all three displays.
It would really help me with my work if I could use the laptop screen for email, documentation, web browsing, etc., and an external 27" display that I have for programming and a 24" TV for multimedia stuff.
Does anyone have an idea where I might look to see if I can fix this problem?
