Hello,
I hope I've got the correct mailing list for this one.
If there's a specific list for XFree86, please let me know.
I am trying to setup my XF86Config file so that I can use 1024x768 with
256 colours. I've setup a corresponding mode in the "Monitor" section of
the file and I'm referencing it from the "Display" subsection of my "Screen"
section, however I think I'm coming unstuck with the HTimings of my mode.
I've currently got them set to :-
HTimings 1024 1048 1208 1264
but I suspect this is wrong because when I run startx I get an error
message which says :-
(--) SVGA: Mode "1024x768i" needs hsync freq of 28.16 kHz. Deleted.
and so the mode can't be used and the X server doesn't start.
I don't know what the HTimings mean and the XF86Config man page doesn't
really explain them, so I'm a bit lost. I've tried other values, but
I'm worried that I might damage my monitor.
Can anyone help?
Here's the full output from startx, following by relevant sections (I think!)
from my XF86Config file ...
