From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; fr-FR; rv:1.6) Gecko/20040113 Description of problem: The installation process is unable to probe the monitor of a Dell Latitude CPx laptop. The video card is an ATI Technologies Inc Rage Mobility P/M AGP 2x. The monitor is a 1024x768 TFT display. Details here: http://docs.us.dell.com/docs/Systems/pcpxhj/en/ug_a02/specs.htm Version-Release number of selected component (if applicable): XFree86-4.3.0-45.0.1 How reproducible: Always
# system-config-xfree86 --reconfig * ddcprobe returned bogus values: ID: None Name: None HorizSync: None VertSync: None Trying with card: ATI Rage Mobility #
That's not part of XFree86. Reassigning...
Does system-config-display actually start at all?
Yes, it starts without problem. It just can't recognize the monitor.
Ok, good. Some LCDs (especially some older laptops) don't have the ability to be ddcprobed. Since there's no way to tell what kind of monitor it is, we try to use some generally safe sync rates so that the program will start. Then you can go into the Monitor dialog and select the correct model. Other than that, there's nothing we can do to fix the problem since we can't get any probing information from the hardware.
Ah, OK. I seem to recall this used to work with Red Hat Linux 9, which is why I've reported the bug. However I'm not 100% sure about that, I could be wrong. If you think the problem is that the monitor is not DDC capable, there's indeed no point in looking into this.
Dimitri: could you attach your X server log?
