Now I need to know how that helped. Do you used a non-default mode? The change had 2 parts and I should have split it for testing. It fixes the window sizing and constructors. > 2) I still can't enter KDB using Ctrl-Alt-ESC, while booting, after > booting, after login and while shutdown - nothing happens. > boot -d enters KDB normally, but the keyboard sequence handler is > broken, not boot -d. Try "<newline>~b". It is an old bug that Ctrl-Alt-ESC (and Ctrl-PrtScr) are misconfigured by default. But I think the misconfiguration is the same for vt. There are about 3 layers of options that have to be set to "enable" or not set to "disable" to enable these keys. Bruce
