Wierd. It's no big deal I guess. Out of interest I'm wondering if it's distro related, or the way I upgraded. I just "upgraded" to Kubuntu 11.10 if it matters and used the x swat ppa to install the nvidia driver.
Very happy with this upgrade. I upgraded recently to the oddly named "GTX 560 Ti with 448 cores" since those were in stock in a lot of places. It's actually a GTX 570 sans 32 cores, a GF110 chip instead of GF114.
But the previous NVidia drivers for Linux had problems, waking up from suspend to disk or ram was a little hit-or-miss. More annoyingly, opening a new tab in browser (Firefox or Chrome) from another application (Thunderbird or urxvt) often turned the display into a blinking mess needing a reboot to get the display going again. Otherwise system kept running just fine, remote access was still working.
Now, with the 295.20 drivers things are working great. Haven't had a single problem waking up. With the browser tab thing there's still sometimes a pause for a few seconds, but display resumes after that.
