Console video gets lost

I have an intermittant problem where I'm running Enlightenment in cntrl-alt-F7 and KDE in cntrl-alt-F8. The video in KDE will go nuts, E will be ok - if I drop to any of the consoles the text doesn't show up on the screen although they function properly. To solve the problem I do an init 3 then an init 5 and everything's ok again. What can I do to prevent this from happening? -- (o< //\ Powered by SuSE Linux V_/_ Virusproof.
