Hello,
Until this morning, my Lenovo Thinkpad T430 running KDE on Fedora 19 was
working fine sitting on a base with a second monitor attached. I removed it
from the base and connected another second monitor (a projector) and things
were still fine. When I put it back into the base, the laptop screen went
blank, and it was using only the second screen. When I remove it from the
base, it uses the built-in screen, but as soon as I put it into the base,
it only uses the second screen. Interestingly, when I restart, it uses both
screens properly until after I log in.
Any advice? Thanks!
In a terminal window, type:
xrandr
to determine whether it thinks that the laptop screen and the external
monitor are connected or disconnected. If the laptop screen is connected
but blank, then it sounds like a hardware problem.
Also, some laptops have a key that you can press to rotate through whether
all the screens are active or not. Does the Lenovo have one?
