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 ... startx output ------------- XFree86 Version 3.1 / X Window System (protocol Version 11, revision 0, vendor release 6000) Operating System: FreeBSD 2.0 Configured drivers: SVGA: server for 8-bit colour SVGA (Patchlevel 0): et4000, et4000w32, et4000w32i, et4000w32p, et3000, pvga1, wd90c00, wd90c10, wd90c30, wd90c31, wd90c33, gvga, vgawonder, tvga8800cs, tvga8900b, tvga8900c, tvga8900cl, tvga9000, clgd5420, clgd5422, clgd5424, clgd5426, clgd5428, clgd5429, clgd5430, clgd5434, clgd6205, clgd6215, clgd6225, clgd6235, ncr77c22, ncr77c22e, cpq_avga, oti067, oti077, mx, al2101, cl6420, video7, generic Using syscons driver with X support (version 1.3) (using VT number 4) XF86Config: /usr/X11R6/lib/X11/XF86Config (**) stands for supplied, (--) stands for probed/default values (**) Mouse: type: Microsoft, device: /dev/tty00, baudrate: 1200, 3 button emulation (**) SVGA: Graphics device ID: "Any Trident TVGA 9000" (**) SVGA: Monitor ID: "Generic Monitor" (--) SVGA: Mode "1024x768i" needs hsync freq of 28.16 kHz.
