No virtual console in Toshiba Satellite L500


I have openSuSE 11.2 installed in my Toshiba Satellite L500. The video card is an ATI MOBILITY RADEON HD4650 and the screen is detected as being a SEC SAMSUNG LCD MONITOR. When I try to use any of the usual combinations to get a virtual console (Crtl+Alt+F1, Ctrl+Alt+F2, etc), the screen just freezes. When the screen is frozen, if I press Ctrl+Alt+F7, I get back to KDE (or Gnome). I can run all the command line utilities in something like Konsole, but sometimes I would like to have something just running in the background…
