When this value is read from /etc/rc.conf at startup and is excessively high it can cause the screensaver to take over the screen by remaining continuously active. The user can type commands, but cannot see the output. This is only a bit annoying, but a new user might not know how to correct the problem. >How-To-Repeat: Enter the /stand/sysinstall program. Enter the Post-Install Configuration Menu. Select Console settings. Select Screensaver settings. Select the time-out interval setting and enter 2147483648. Exit the sysinstall program and reboot. The screensaver should take over the screen as soon as it is started by the startup script. >Fix: *** /usr/src/release/sysinstall/config.c.orig Wed Apr 1 00:13:25 1998 --- /usr/src/release/sysinstall/config.c Wed Apr 1 01:53:02 1998 *************** *** 461,469 **** int configSaverTimeout(dialogMenuItem *self) { ! return (variable_get_value(VAR_BLANKTIME, !
