kernel-image-std-def-2.6.32-alt15
kernel-modules-drm-std-def-2.6.32-alt15
xorg-dri-intel-7.0.4-alt9.M41.1
xorg-drv-intel-2.4.3-alt0.M41.1
xorg-server-1.4.2-alt10.M41.1

The system boots in some framebuffer mode on the text linux consoles, then X (and KDE) starts, and after that switching to any linux console makes the screen blank. 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.

More info about the system is attached, and:
