I recently tried switching from linux-2.6.23-gentoo-r9 to linux-2.6.24-gentoo-r7. The latter is configured as indentically as possible to the former, but when I run X under the 2.6.24 kernel, one of my two displays blinks off every 10-20 seconds (it's off for about 1 second, then comes back on).
The blinking doesn't happen with the 2.6.23 kernel. The blinking doesn't happen in console mode. I'm running nvidia-drivers 169.09-r1 with a NVIDIA GPU Quadro NVS 290 (G86GL), connected via DVI to dual Samsung 204B displays running at 1600x1200. There's nothing in the system or X logs that conicides with the blinking. I'm a bit baffled as to how to troubleshoot the problem other than stick with 2.6.23 and hope that a newer kernel rev fixes things... -- Grant Edwards grante Yow!
