There seems to be a lot of confusion about what modes the UDB's TGA
chip can support. The TGA is more or less a DEC ZLXp-E1 graphics board
and it's hardwired for 16 different Clocks/Refresh Rates/Resolutions in
order to directly support Digital monitors.
These modes are also hardwired into the TGA X86 driver. I've tried to
fool the driver into using the clocks to drive other resolutions that
they didn't support, and the driver responds with ``Not a hardwired
I have the Sony 17sfII monitor, and after crossreferencing the ZLXp
modes with standard VESA/Sun modes, I came up with these, which will
work fine for you:
# VESA 640x480 @ 72Hz
Modeline "640x480" 32.00 640 692 796 848 480 491 513 524
# VESA 800x600 @ 72Hz
Modeline "800x600" 50.00 800 862 986 1048 600 615 647 662
# VESA 1024x768 @ 70Hz
Modeline "1024x768" 75.00 1024 1100 1252 1328 768 777 797 806
# Sun 1152x900 @ 66Hz
Modeline "1152x900" 92.98 1152 1240 1416 1504 900 909 927 936
# VESA 1280x1024 @ 60Hz
Modeline "1280x1024" 1280 1384 1592 1696 1024 1033 1054 1063
I used the equations DCL = HSF * HFL and DCL = RR * HFL * VFL to
compute these, and placed sync start and sync end pulses equally spaced
between the others. You don't need to adjust them...just use the
monitor controls on the 17sfII to fill and center your screens.
I am looking for a 1024x768 @ 72Hz mode as well as the TGA supported
modeline for 1024x864. When I get them working, I'll post here.
You can find 15 out of the 16 TGA clocks by using X -probeonly and
adding Clocks lines to the "Device" section of your config file. The
remaining clock is reserved by DEC.
I hope this helps. Now if only someone could tell me why my external
Philips CD-ROM only works 50% of the time. ;-)
