Switching back to the console with X (no. 7) doesn't help. If I start another X, it is shown correctly on the screen, but switching from the second X (even to the first X) doesn't work correctly: the screen is again blank. I have just upgraded the kernel from kernel-image-std-def-2.6.30-alt14 ; on that kernel this X worked well (= with no crashes or other big problems). Workaround: never switch to other linux consoles from X.
