Can´t rotate 4th display -> X crash
Hi there,
great work with version 21! After setting up a new machine I tested fedora to see if it would support 4 displays out-of-the-box as the former distro did not. I need my system to work so I can too ;)
Installes is Fedora21 on a AMD system with an onboard GPU (HD3000) and an discrete graphic card (HD5450). Connected are four displays: 2x 1680x1050 and 2x 1920x1080. Both 1920s on digital output from the HD5450 in normal orientation as well as one 1680 in pivot over VGA. The fourth screen is supported by the onboard GPU via VGA, also in pivot orentation
I was very impressed as the live system enabled all of my four displays from the get go so I installed on my SSD. The struggle started as I tried to setup the screens in the proper orientation. The 1680 on the discrete card works just fine in pivot but when i try to turn the 4th display in the settings manager it crashes my X server.
The last 4 hours I did tried to fix it and searched the web up and down. My conlcusion from this is, that it might asks too much from the virtual screen which unifies the displays in one large SCREEN. The output from xrandr all lists them in the same "screen0". I disabled it at the moment as I can´t use it in this horizontal orientation.
What I would like to ask is, if there is a way to start a second SCREEN with just the 4th display or if I can enlarge the virtual screen to support it.
