I am considering getting a Geforce 660 to run 3 or 4 monitors in KDE and wondering if anyone has any experience? I know the 660 can run 4 monitors in twinview, but I’m wondering how well Kwin handles that, especially using monitors of different resolutions. Currently I am running three monitors off two cards with two separate X screens. It works relatively well, but kwin sees the two twinview monitors as one big screen and maximizes windows across both monitors. If I disable the third monitor and only run one X screen, it sees the twinview monitors as separate and behaves correctly. I’m not sure if this is a limitation of separate X screens, or if Kwin just doesn’t handle more than 2 monitors properly. Before I buy the card, I’m wondering if anyone has experience using twinview with 3 or 4 monitors in KDE. Specifically I am wondering if the following work correctly:
Maximize windows to each monitor
Maximize windows by dragging them to the top of each monitor
Tile windows by dragging them to the side of each monitor
Games run correctly on one monitor
My setup would be two 1680x1050 monitors on top, plus a 2560x1440 and 1920x1080 on bottom. Any reason that wouldn’t work?
