[Xpert]Radeon VE getting faulty EDID from digital flatpanel
Hello, I have recently got this digital flat panel to work with a Radeon VE (QY) in xf4.1.99, using a quite unusual approach. The problem is that the panel is not getting the timings it requires, even though the X server successfully reads the EDID info. To get it to work I hav to boot up with the panel connected to the DVI connector on the Radeon VE, then disconnect it before starting the X server, so that the EDID cannot be read (just turning the panel off doesn't help), and then connect it after the server has come up. vesafb and the vesa driver in XFree works great, but a bit slow. A modeline that would work for the screen (according to fbset) is: Mode "1024x768-76" 78.654 1024 1056 1184 1312 768 772 776 792 "-HSync" "-VSync" But the server doesn't like that very much (from the log: "(WW) RADEON(0): Mode name H^Q`^V@^M^Mp^V@p^V@x^V@x^V@ is invalid)") EDID seems to return 65.0 1024 1048 1184 1344 768 771 777 806 Is there a way, like in nvidias binary-only driver, to disable EDID that I've missed? This is cvs version 4.1.99.1 with and without the radeon driver from 4.1.99.2. I haven't found any related changes in the CVS since the beginning of December. Did I miss something here when looking through the diffs?

Option "noDDC" should work. I put this in the monitor section, but I don't think that it has to go there. Option "noVBE" might work too. -- Dr. Andrew C.

Re: [Xpert]Radeon VE getting faulty EDID from digital flatpanel
for radeon/ve's, and radeon/all-in-wonder's with dvi-d connections what i find works best is to let XFree86 -configure build an XF86Config, then add Modes "1024x768" (specifically, the exact size of the flat-pannel) to the appropriate display depth (NOTE: NO OTHER TIMING INFO or ModeLine for 1024x768!), and then add a VertRefresh 59.0 - 61.0 line in the Monitor section. this works perfectly for the 3 flat-panels monitor's with dvi-d inputs that i've tried it on: sony sdm-81 philips brilliance 180p (this has problems in non-x11 with dvi-d input in general) hp (10x7, two years old...) (the first two are 1280x1024...) please note that it is VERY important to have the dvi-d plugged in at the bios-boot time, before doing any of this. hot -elh > Hello, > I have recently got this digital flat panel to work with a Radeon VE > (QY) in xf4.1.99, using a quite unusual approach. > > The problem is that the panel is not getting the timings it requires, > even though the X server successfully reads the EDID info.
