I went and tried this using this kdbcontrol command in my .cshrc: # added to increase scrollback to 1000 /usr/sbin/kbdcontrol -h 1000 This gave me 1,000 lines when I'm logged into the console however, it resulted in a "Inapproriate ioctrl for device" error when using xterm (xfterm4) under xfce4. So I removed the "kdbcontrol" from my .cshrc and used a "-sl 3000" option to launch xfterm4. So launching "xfterm4 -sl 3000" now does the trick! Regards, Michael
