a bug looks very similar to
Bug 448075 - radeon: No modes on output DVI-0 (Radeon 7500) https://bugzilla.novell.com/show_bug.cgi?id=448075
but is reproducable on nVidia GeForce
This was a temporary bug in radeon driver (not existent in 11.1 final), not a bug in radeonhd/nv driver or even a general bug in Xserver. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Option "monitor-DVI-I_1/analog" "Monitor[0]" and add a line Option "Enable" "true" to the "Monitor" section.
You added the "Enable" to the wrong monitor section. It must be the "Monitor[0]" section, not the "EXT" monitor section. BTW - you don't happen to use a KVM switch? -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

No, I haven't a KVM switch. A picture from DVI-I output is much better then picture from VGA output (ripple) on my videocard. :)
Err - we're talking about a DVI/VGA adapter, aren't we? So there is no digital output involved. Also, the monitor should just be detected (TM). Can you please run rhd_conntest, once for no monitor connected, and once per one(!) monitor connected (you probably have to type in the command, then disconnect the viewing monitor, and press return blindly)? Please attach the output of all three commands, and annotate what monitor was attached in each case. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Line Option "Enable" "true" removed from "Monitor[0]" section.
No, you should remove the Monitor "Monitor[0]" in the Screen section. The Option "Enable" "true" should remain for now. BTW - no need to conntest with or without adapter removed - either connect the monitor to the card with the adapter, or remove every connection from the card. Also, device 2:0.1 is a pseudo device on ATI cards, no need to test that. Additionally, missing conntest output for VGA attached. I just noted from the logs that your card is another one with HPD pins swapped. I'll add a fix to radeonhd. Until then you should add Option "HPD" "swap" to the Device section in xorg.conf. If that finally works, you can try to remove the Option "Enable" "true" from the monitor section. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
