Well, I've been using Nvidia cards with the nvidia-driver and dual-monitor support as well, and it has been fantastic, until I upgraded my Ubuntu install, got Unity without asking for it, after which multi-monitor support was completely broken. My colleague who has 2 screens of a slightly different type (all are Lenovo ThinkVision) and is running Arch with Gnome 3, has been experiencing random multi-monitor glitches since day one. Sometimes for no apparent reason one of his displays doesn't get a signal after waking his laptop from sleep or hibernate, and the only way to resolve it is a reboot. To make a long story short: we could exchange anecdotes all day about the state of 'Just Works' on Linux, but at the end of the day, I think no one with enough experience using various Linux distros and OS X, can honestly and sincerely say Linux is even close to OS X in that aspect. Myself, I've been using Linux since Slackware 4 and have tried about 10 different distro's over time, alongside OS X for the last 5 years or so. Up to this day, I regularly run into problems that need fixing on Linux, particularly after upgrades, or when switching hardware. Whether it's Wifi cards, USB hardware, multi-monitor support, network configuration issues, software that stops working, system library problems: there's always something. OS X on 3 different machines, from OS X 10.4 through 10.7, I've only had one issue that required maintenance once, on a b0rked upgrade. It was pretty nasty, but fortunately OS X has Time Machine and target disk mode, so in no-time I was able to pull off any important data just to be sure, re-install the OS, restore my Time Machine backup, only to find out everything was back to normal, to the point I didn't even need the files I had to pull before the restore. |
