Sorry for not being more complete. I posted this question once before without a solution. I have a Dell 1721 AMD laptop with an AMD/ATI RD690M {Radeon Express 1200/1250/1270] graphics controller. The system boots
Earlier thread mentioned you also have Intel Graphics. ??? Earlier thread also implied you have two external monitors. Did you mean output/input ports when referring to trying HDMI instead of VGA or vice versa?
fine, as I think I suggested, but the sync on the monitors is wrong if I boot with the external VGA monitor plugged in. The monitors are garbled. If I unplug the external monitor, and ctrl-alt-backspace back to the X server, the laptop comes up clean. I can the add the second monitor as you described. My goal is to be able to boot the system using the external monitor only.
You still haven't clarified much in this thread. When exactly does the garbling begin? What are your displays' native resolutions? (2405FPW 16:10 1920x1200 external != UXGA; == WUXGA) (1721 Inspiron laptop 16:10 1440x900 != UXGA; ) Web specs I found about your laptop disagree whether 1920x1200 is also supported, or an optional native superceding 1440x900. WXGA+ == 1440x900 UXGA == 1600x1200 WUXGA == 1920x1200 What does trying "unified outputs" mean? Which cable type connected to your external display(s?) was/were working OK in Fedora? Regardless the answers to these questions, /etc/X11/xorg.conf and /etc/X11/xorg.conf.d/* remain viable as means to configure displays so that they function correctly. My guess is doing so will solve your problem, largely based on the info I gathered that suggests you have two displays that have non-identical native modes. http://fm.no-ip.com/Share/Linux/ has some config files that provide minimal framework for constructing your own manually. http://lists.x.org/mailman/listinfo/xorg is another place to go for help. -- "The wise are known for their understanding, and pleasant words are persuasive."
