VGA & DVI resolution issue

[mithrandir77]

Hi all,

I have a problem just attaching a DVI (DVI to HDMI) cable to my graphics card (NVIDIA
PCI-E) for a secondary monitor (my LCD tv): it makes my opensuse 11 to
boot using an unsupported graphics mode for the VGA output and
so it makes the VGA monitor unable to reach the new resolution. The
only way to makes the system to boot normally seems to be to unplug
the DVI cable
How can I make the system to keep the normal video mode for VGA output
and then to configure it to uses the DVI output as alternative screen and this just only when I want use it?
Do I have to use official nvidia driver to do it?

Thanks

Valerio

Hi
Have you tried setting the vga mode at boot (in the boot options in
grub)? eg 1024x768 is vga=0x317

Yes, it works, but I don’t understand why it is modified when I plug the DVI cable
