On low resolution screens often comes problem with large dialog/window, which is over display range, so there is no possible to reach buttons placed on bottom of window (no visible - no clickable).
This problem concerns about FailSafe mode (640x480), and also about normal working on new small laptops (Asus EEE, HP mini, Dell 910, Acer one... screen height 600px or 480px!) and eventually old computers.
I think, there should be possibility to switch to fit more into small screen. Ideally to make it by one button:
reduce fonts, window decorations, ribbons/panels, icons, space between rows... I know, there is possible to set "pixels per inch", but this don't apply on all elements (buttons...) and looks ugly. Better is special theme.
Apropos... the MS-Windoze is more thrifty than Gnome Ubuntu to fit contents on screen, and additional - the XP offers switch to very thrifty Win2000/Win95 mode.
It makes me angry especially when trying to select higher resolution in nvidia-settings during 640x480 failsafe -> it's impossible !!
