I have just replaced my monitor and the video card.

Now, suddenly, when I boot the computer I get the error message: "Undefined
mode 348" and am given the option of selecting a video mode to continue the
boot (and I select '31A' which gives me 1280x1024).
your video card, IMO requires an extra xorgconfig to be run.

test it according to this.

Xorg -config -retro

In menu.lst the entry for the boot video mode is 'vga=348' (and has been for
years) which equates to a resolution of 1440x900.

The monitor supports this resolution of 1440x900.

Does anyone know, please, in which 12.1 oS file the video resolutions are
defined so that I can check if '348' is there?

(There were some upgrades done this morning and I wonder if one of them
produced this change?)


Thanks Sujit for your response.

As you would have read by now the problem is solved with the use of 'hwinfo --framebuffer' as I wrote in my reply to Brian.

I haven't tried the Xorg -config test as yet but will do so and will add it to my list in the little black book of 'useful things to know'.

second sees what another has grasped, the third grasps nothing and sees nothing.
