I recently received my new hardware. I installed Ubuntu 15 but got an error with my dual screen. I downgraded to the stable 14.04 ... But still the same.
I have two monitors connected in HDMI and DVI on my GTX970 by Strix.
The two of them are mirroring themselves. I tried to go in the "Displays" preference menu, but the window shuts down with :
Sorry, Ubuntu 14.04 has experienced an internal error.
The detail reports this message :
unity-settings-daemon crashed SIGABRT in g_assertion_message()
Also, the Ctrl+Alt+T shortcut does not work.
It's a fresh install, I did not do anything ... Is this the hardware ? What can I do to fix it and be able to extend my desktop ?
