I pulled the latest xf86-video-intel source from freedesktop.org, and it magically cured the symptom.
My Xorg.0.log still shows the same error entries as before: (EE) intel(0): Unable to write to SDVOCTRL_E for SDVOB Slave 0x70. So, at least they are not the culprit. Now that the pain is gone, I'll probably never know the real cause. Andrew Sackville-West wrote: >> I wonder how modlines and the control panel interacts.

Though we only have one, I believe this is important. I used "Monitor-TMDS-1" instead since my monitor is connected to SDVO DVI connector. But I couldn't get X to use my modeline. And I did not try harder because the X is already in the right mode. (At first, I suspected the refresh rates were wrong. But they turned out to be correct according to the monitor manual.) The problem is that some parts of my monitor thinks it is in "640x350" resolution and complains about it. Thanks, T. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
