I am unable to get 24bbp at 1280x960 on my Matrox Mystique under XFree86,
although it runs happily this way under Micro$loth 2000 pro.
The error reported in the XFree86 log is "not enough memory for this mode".
The log file reports 4096K ram, which is correct. This is what is
physically
installed on the Mystique, and is also what is reported by M$ 2000.
It will run 1280x960 at 16bpp. (I test this by starting X with -depth 16)
It makes no difference whether I use +xinerama or -xinerama. This problem
was also observed with XFree86 4.1.x.
Seems to me that if M$ 2000 can drive this card at 1280x960x24bppx75hz then
XFree86 should be able to as well. But I am stuck.
TIA
