Description of problem: On certain ATI chipsets (e.g. X700) using LCD/Laptop displays, the Radeon driver requires the extra option: Option "MonitorLayout" "LVDS,AUTO" Otherwise the primary display remains blank, and this obviously makes installing Fedora impossible unless textmode is used, or the vesa driver is forced. Version-Release number of selected component (if applicable): 0.3.32 How reproducible: Always. Steps to Reproduce: 1.Boot from FC7t2 Live/Install CD, on system with ATI graphics and an LCD display as the primary display. 2. 3. Actual results: Blank screen. Expected results: Primary display should be activated and visible. Additional info: This is now an old and persistent problem, going back as far as FC5 IIRC, so I'm surprised it has never been addressed before. Casual inspection shows a few related bugs here, but nothing that nails the issue with the above option line (which is well documanted in various other places). It would be nice to have this special case patched to enable ATI/Laptop users to install in graphical mode, in time for the final release of FC7. Not sure if this should be passed upstream to Xorg, is this a bug or a "feature"?
It's really an ati driver bug. The problem is we _should_ be getting a connector table from the BIOS, but we're parsing it wrong, and therefore think that there's no LVDS hooked up. I suspect we should just force to LVDS,AUTO if we're on a laptop chip and we detect NONE,NONE (which is the usual symptom).
Version-Release number of selected component (if applicable): radeon 1.25.0 20060524 (kernel-2.6.20-1.2949.fc7)
