Ultra 1, RH6.1 with updates, CG6: if X is running, I am not able to switch virtual consoles, i.e. I press ctrl-alt-f1 and the mouse-pointer disappears but nothing else happens; the X screen is still visible and the input from the keyboard goes to the active X window. When the mouse is moved, the mouse-pointer becomes visible again. Effectively virtual consoles are unusable (while X is up). On sparc-list the same problem was reported for SS2 with CG3 and for Ultra 1 with Creator 3D. There is probably a bug in the framebuffer code in the kernel.
Problem remains with kernel-2.2.14-5.0.
Assigning to Dave Miller, sparc guru.
Problem disappears if contents of '/etc/sysconfi/desktop' is changed from 'KDE' to 'GNOME' which means use gdm for graphical login instead of kdm. So maybe there's a problem with kdm and not with the kernel or X. Packages used: kdebase-1.1.2-33 kernel-2.2.14-12 XFree86-Sun-3.3.6-20
