I'm having an odd issue with a non-headless server. Normally the consoles behave as they should, but for some reason they've all decided to go blank (monitor goes to standby and all.)

If I, either blindly or via SSH, put it to runlevel 4 X comes up properly and I can log in. Given that I don't think it's a hardware issue, rather some problem with the framebuffer driver.

This system is constantly busy, and I'd rather not have to reboot it if I can avoid it. Anybody have any idea for how I can reset the framebuffer?

Linux 2.6.15; SMP; non-preempt.
Video adapter is an ATI unit over AGP.

Thanks

Rerun your xorgxonfig or you can reset it I believe throught pkgtool.
