A very neat trick. X can now be ended correctly. Unfortunately, any
scrolling on any VT afterwards gives me a corrupted screen - parts of
the screen from other VT's are inserted below, or over the cursor
position, and at 'half-line' intervals. In typing this email, I've seen
it 5 times already.
I'm willing to test anything - but the corruption is alway gone after I
switch VT's. So getting a screendump is not easy.

Thanks!
