studio display config

[Paul Brossier <piem@altern.org>]

hi all,

I have been trying to set up a decent config to run X on a Studio
Display. I can get a 1280x1024 resolution by changing the hsync and
vsync values as follow:

Section "Monitor"
        Identifier      "Generic Monitor"
        #HorizSync      28-50
        #VertRefresh    43-75
        # needs larger values for apple studio display
        HorizSync       28-70
        VertRefresh     43-120
        Option          "DPMS"
EndSection

but i couldn't get the largest resolution (1400x1050) to work. adding
"1400x1050" to the Modes line, along with Virtual 1400 1050, i get a
gray screen. if i increase the freqs any more, X starts but the screen
goes gray again. here are some of the relevant lines in Xfree86.0.log:

(II) NV(0): Not using mode "1600x1200" (no mode of this name)
(II) NV(0): Not using default mode "1400x1050" (width too large for virtual size)
(--) NV(0): Virtual size is 1280x1024 (pitch 1280)
(**) NV(0): *Default mode "1280x1024": 108.0 MHz, 64.0 kHz, 60.0 Hz

lspci says this about the card:
0000:f0:10.0 VGA compatible controller: nVidia Corporation NV34 [GeForce FX 5200 Ultra] (rev a1)

any one had more success?

thanks, paul
