I've tried to compile & install the latest DRI CVS ATI Radeon driver, but it seems DRI CVS has not yet picked up the latest changes from xfree86 CVS for DVI support at high resolutions. I'm using the xfree86 CVS ATI Radeon driver with an Iiyama AU4831D DFP at 1600x1200 attached to the DVI interface; with the DRI CVS ATI driver there was no picture (= completely black pickture) on the DFP. This is more or less the same behaviour as seen with the xfree86 4.2.0 release version of the ATI Radeon driver. I've had a look at revision 1.17 of radeon_accel.c on DRI CVS, and it seems you've changed (among many other things) the Mono8x8PatternFillFlags to use BIT_ORDER_IN_BYTE_MSBFIRST instead of BIT_ORDER_IN_BYTE_LSBFIRST; and removed the RADEON_GMC_BYTE_LSB_TO_MSB flag in RADEONSetupForMono8x8PatternFill. This was the change that has fixed the problem for me as well, using xfree86 CVS. The other change you made related to "8x8 mono pattern filled rectangles" - the "Take care of endianness" stuff in function RADEONSetupForMono8x8PatternFill() - does not make a difference on a little endian architecture like x86 but I guess it's fixing some corruption with swapped vertical lines that should occur on big endian architectures. Have you been able to reproduce the issue with the horizontal flipped pixels and the 2d accelerated "8x8 mono pattern filled rectangles" op? I'm asking because I posted the same question on usenet and from the 3-4 people that responded, apparently noone was able to reproduce this problem. What's the explanation for this? _______________________________________________ Xpert mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/xpert
