Hi, My workstation is currently running Slackware Linux 14.1 64-bit, and I'm considering replacing that by CentOS 7, which I've already installed on my laptop. The PC has an NVidia GeForce GT 520 video card with two 19'' monitors attached to it. I'm using the proprietary 'nvidia' driver. I vaguely remember having read somewhere that RHEL/CentOS 7 with GNOME 3 had trouble with dual monitors. Now since this is my main workhorse PC, I thought I'd rather ask before migrating, just to be on the safe side. Anybody on this list running CentOS 7 on a similar hardware configuration? If I remember correctly from the time spent with CentOS 5.x, the proprietary 'nvidia' drivers are best configured using the third-party ELRepo package repository. Correct me if I'm wrong.
