Created attachment 73492 [details] dmesg | grep nouvea, with 3.6.10-4 Hello, I am running fedora 18. I have 3 monitors hooked up to a geforce gtx 660 ti, 2 via the DVI connectors, and 1 via the displayport connector. With Kernel 3.6.10-4, everything works fine. Upon upgrading to 3.7.2-201, the displayport connected monitor stops working and says unsupported display mode, optimal resolution is xx (the monitor is set to that resolution and hz). The unsupported display mode is displayed even in runlevel 3. I have changed the monitor connectors around and whichever is connected via displayport stops working. If I boot back to 3.6.10-4, everything works fine. If I do a dmesg |grep nouveau , on 3.7.2-201, I see: 2.012167] nouveau E[ DRM] failed to create kernel channel, -22 This message does not get displayed with 3.6.10-4.
