Re: DDC on dual head - was Re: [XFree86] 4.2.99.4 and mga dualhead
I think that these two problems dont have anything in common but the ChangeLog reports (see below) that both issues are fixed in 4.2.99.901. Ive just checked out and will soon compile and try on my G450. 806. Fixed patch 760: VBEInit takes entity index, not screen index (Egbert Eich). Thats the crash fix. 818. xaaStateChange.c was not calling RestoreAccelState before doing CPUToScreenTexture and CPUToScreenAlphaTexture, which seems to be the reason why RENDER acceleration was broken on some dual-monitor MGA cards (#5602, Nolan Leake). Thats the fix for the font / cursor problem. Jürg Billeter ___ XFree86 mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/xfree86

Has this fixed the RENDER problem with truetype fonts (the problem that was displaying truetype fonts on the wrong Xinerama screen) There was a patch submitted but I haven't had chance to apply it and test on my G450 yet. mike On Tuesday 04 Feb 2003 12:30 pm, Dr Andrew C Aitchison wrote: > On Tue, 4 Feb 2003, Egbert Eich wrote: > > Jürg Billeter writes: > > > Hi > > > > > > I've upgraded from 4.2.99.3 to .4.

To test this you need to check out > CVS head. Ebgert's fix does seem to stop it crashing on my G550. While testing, I've noticed that the mga driver always reports DDC info for the first head. Are there any drivers which give correct DDC info for the second head, or does anyone else have suggestions as to how to fix this ? -- Dr. Andrew C.
