Description of problem:
(I'm filing this against distribution because I'm not sure whether the guilty
party is anaconda, redhat-config-xfree86, firstboot, hwdata, or something else.)
A desktop system with a Dell E171FP monitor is being automatically configured
for 1024x768. My understanding (according to my boss at work; I didn't see this
myself) is that with Red Hat 9, there was some kind of prompt for the resolution
at some point (I'm guessing firstboot). I definitely saw such a prompt in
firstboot with Red Hat 8.0 on the same type of computer/monitor.
Since that prompt is no longer there, it is now more important that the monitor
is configured correctly automatically by the time the gdm login screen appears.
Version-Release number of selected component (if applicable):
Fedora Core 0.95
Steps to Reproduce:
1. Install Fedora Core.
2. Notice monitor is fuzzy (as if in non-native resolution).
3. Run redhat-config-xfree86.
4. Change the resolution.
5. Log out and back in.
6. Notice that monitor is suddenly sharp.
Actual Results: See the steps themselves
Expected Results: Ideal expected result: 1280x1024 resolution
Less-than-ideal expected result: firstboot prompts for resolution

Is there any way to specify in hwdata or whatever that a monitor absolutely
should be set to a certain resolution by default if at all possible, even if it
happens to support other resolutions? The only way I can think of doing that
would involve adding a new field in MonitorsDB...
(BTW, MonitorsDB says "DEL300F" while ddcprobe says "DEL300f". Notice "F" vs.
"f". Would that cause any misbehavior?)
I'd rather not add a field in the MonitorsDB. Probably a better solution is to
add a screen to firstboot to allow people to select their preferred resolution.
It's too late for FC1, but we can shoot for FC2.
Ok, that sounds good to me.
Should this be re-marked as enhancement for configuring resolution in
Implemented in firstboot-1.3.3-1 and system-config-display-1.0.4-1.
