Re: X 4.01 gives blank screen

[Bob Nielsen <nielsen@oz.net>]

Thanks for the advice.  I changed Default Depth to 16 and now I can
get a display, but it seems to decide that any resolution greater than
800x600 is not valid.  I know that with only 2 MB of video memory I
can't get some of them, but 1024x768 works fine with XFree 3.3.6.

I get this line repeated 5 times:

(WW) CIRRUS(0): Default mode "1024x768" deleted (bad mode clock/interlace/doublescan)

and later (once):

(WW) CIRRUS(0): Default mode "1152x864" deleted (bad mode clock/interlace/doublescan)

Still later:

(WW) CIRRUS(0): Mode "1920x1440" deleted (no mode of this name)
(WW) CIRRUS(0): Mode "1856x1392" deleted (no mode of this name)
(WW) CIRRUS(0): Mode "1792x1344" deleted (no mode of this name)
(WW) CIRRUS(0): Mode "1600x1200" deleted (no mode of this name)
(WW) CIRRUS(0): Mode "1280x960" deleted (no mode of this name)
(WW) CIRRUS(0): Mode "1152x864" deleted (no mode of this name)
(WW) CIRRUS(0): Mode "1024x768" deleted (no mode of this name)
(--) CIRRUS(0): Virtual size is 800x600 (pitch 1024)
(**) CIRRUS(0): Default mode "800x600": 49.5 MHz, 46.9 kHz, 75.0 Hz
(**) CIRRUS(0): Default mode "640x480": 36.0 MHz, 43.3 kHz, 85.0 Hz
