Comment 10 for bug 327386

I have the same problem but I cant edit it by going through the dialogs, they're too big and I can't get anywhere with them. Is there another way to do it?

I tried xdpyinfo | grep dimensions and it showed 1152x864 pixels (322x241 miillimeters)
And xdpyinfo | grep resolution shows 91x91dpi. But it made no difference. I used grandr to switch the resolution to 1024x768 (although I use 1280x1024) and hit apply but it makes no difference.
