Description of problem:
Kudzu does not appear to detect changes in monitors between reboots.

How reproducible:

Steps to Reproduce:
1. Use a Red Hat Linux 8 machine with a given monitor
2. Turn off computer and connect a new monitor to the same PC (preferably a 
monitor that doesn't support the same res/refresh as the monitor from step 1 to
demonstrate how scary this is for the user)
3. Turn on computer again
4. Watch the new monitor choke on the new res/refresh rate

Actual Results:  X did not come up because the new monitor doesn't handle the
configured resolution of the old monitor

Expected Results:  kudzu should detect the new monitor and prompt to configure X

Additional info:

This effectively breaks X, so I've set it to "High" for severity - I hope this
isn't improper.

Comment 1 Bill Nottingham 2002-12-17 00:29:20 UTC
Currently, the DDC monitor probe is only done on-demand by config tools, as it
has caused strange behavior in the past on some graphics chipsets. So, it's not
actually run during the boot time probe.

Comment 2 Jens Knutson 2002-12-17 02:07:44 UTC
Bleh... well, would a "probe by default unless the chipset appears on this
blacklist" system be possible, or is that still too dangerous?

Comment 3 Bill Nottingham 2005-09-23 19:51:39 UTC
Realistically, where it has fallen down seems related almost as much to BIOS as
it does chipset. Which makes this impractical.

The long-term solution is to have the X driver automatically adjust to monitor
changes; that is where progress will be made. Until then, it's unlikely that the
behavior in kudzu will change. Therefore, closing this bug.
