Hello I am using opensuse 13.1 KDE 4.11. On 12.3 I would sometimes
connect to my flatscreen tv as an alternate monitor while using my
laptop. It doesn’t seem to work as well in 13.1. Here is what I did.
When I boot up, and I have the HDMI cable plugged in, I see the opensuse
boot parameters on both my laptop screen and the flatscreen. When it
gets to the kwin screen where I enter a password to login to KDE, the
login screen shows on both my laptop screen and my flatscreen. After I
enter my password to login, when it starts initializing KDE, the HDMI
cable loses signal and the flatscreen says “no signal”; meanwhile I
function fine on only my laptop screen.
If I do the same thing except boot up without the cable plugged in, I
still get “no signal.” In both cases, when I log out of KDE and get back
to the kwin login screen, the HDMI signal returns, and I see the kwin
login screen on both my laptop screen and on my flatscreen simultaneously.
I decided to try an experiment. I logged out of KDE, and then in a
terminal I renamed the ~/.kde4 directory so that KDE would create a new
one with all the default settings. I didn’t delete it because I have a
ton of KDE settings that I don’t want to lose, so I just wanted to try
and completely new setup.
Well, it worked. When I booted into KDE from kwin with a completely
default configuration, the HDMI signal remained, and I had no problem
while in KDE having my flatscreen as an alternate monitor to the right
of my normal laptop screen.
So the problem is clearly somewhere in my KDE settings, but there are a
ton of those and I don’t know where to start looking. Any ideas?
G.O.
