That's what everyone is expecting; they should. But they don't.

Yes, it has influence on the behaviour of svgalib, but it only proves that
the configfile gets read in some way. That was already clear from the fact
that choosing the wrong chipset does really matter.

It doesn't concern VESA drivers. It's a S3 trio64 PCI card.
For what it's worth, here is the config file:
---
# Configuration file for svgalib. Default location is /etc/vga.
# there's no ~/.svgalibrc
# skip mouse stuff. skip keyboard stuff
HorizSync 47 51
VertRefresh 58 61
chipset S3 # S3 chipsets
colortext
modeline 1024x768 62 1024 1112 1166 1282 768 769 775 824 -hsync -vsync
modeline 800x600 50 800 870 930 1030 600 720 728 822 -hsync -vsync
modeline 640x480 43 640 710 762 834 480 650 656 850 -hsync -vsync
---
Narrowing down the options to for example
HorizSync 48 58.8
VertRefresh 58 59.5
doesn't do any good.
What I simply need is that it uses the working modelines. They just get
ignored. So how do I fix that?
Regards, Wim.
