I was surprised to see that the non-free nvidia driver no longer support my old video card.
nvidia says that they will some day support it again, but its a very old card....
The nv driver works well enough, but the new version of Xorg gives a resolution of 1154x864 as default.
In mint 5 xfce you get the vesa standard 1280 x 1024.
It was necessary to manually edit my xorg.conf file and add a display subsection with the mode 1280x1024 explicitly identified.
Examination of the xorg log in mint 5 xfce and mint 6 xfce shows the xorg finds the same modes for the video card and seems to produce the same mode lines for the monitor I'm using (sony CRT).
As best as I could tell the xorg server software picks a viewport size that is smaller than it previously did in mint 5 xfce.
What is the possibility of mint 6 xfce using the method(s) previously used to make the xorg.conf?
