Hi:
I am unable to get the CRT monitor to simultaneously display
what is on my laptop LCD screen!
I will appreciate inputs towards setting up display
on both the LCD and CRT monitor.
The investigation details and technical information
is provided below.
The following approaches were tried:
0.
Approach:
use the display toggle key Fn-F5 (from Acer documentation)
in text mode.
Result:
The toggle key Fn-F5 has no affect.
1.
Approach:
use the display toggle key Fn-F5 (from Acer documentation)
when XFree86 server is running
Result:
The toggle key Fn-F5 has no affect.
2.
Approach:
Plug the CRT monitor cable to the laptop port before booting
the laptop.
Result:
On booting the laptop, the CRT monitor is detected
and the XWindows is displayed on CRT monitor.
The LCD panel is blank.
The toggle key Fn-F5 has no affect.
3.
Approach:
Plug the CRT monitor cable after the laptop is booted up
Result:
LCD Display active. The CRT monitor is blank.
On starting XFree86 server, XWindows is started and
displayed on LCD panel.
The CRT monitor continues to be blank.
The toggle key Fn-F5 has no affect.
