4.10.2 Monitor Configuration Disappears

[culip]

Hi,

I just upgraded KDE to the latest version 4.10.2.

After rebooting the system, my laptop didn't recognize an external monitor, so I hit a hotkey to switch the monitor, but nothing happened (other hotkeys such as brightness controll work perfectly.)

I open "System Settings" > "Display and Monitor" and have noticed the difference from older versions of KDE and can't access to the monitor configurator. I've also tried unplugging & plugging the monitor's HDMI cable, but nothing happens either.

Third-party software called "Jupitor" has monitor settings that recognizes & be able to configure my external monitor; thus the Linux kernel and my laptop & external monitor must have been working correctly.

I'm assuming quite a few Kubuntu or even other KDE users have the same problems. If you know any solution, please advise. Thanks.

Do you have either kscreen or krandr installed?

I had a similar situation (on Raring) where I had been using krandr, but because I didn't have some meta-packages like kubuntu-desktop installed, the new kscreen did not get automatically installed.

As far as I can tell, either works. I'm using kscreen.

I just installed kscreen and it looks rather primitive, but I think it's alright.

$sudo apt-get install kscreen

I think I used to use krandr which I can't find now. I don't know why krandr or kscreen doesn't come automatically when upgrading KDE to v.4.10.3. Unlike your computer, mine has kubuntu-desktop. Um.

Thanks ronw!
