- Far and away the most common cause of this is somebody logging
- out (as opposed to shutting down), and then turning the power off,
- or hitting the reset button. In 4.0.5 both the X login scripts,
- and the gamma program have been beefed up to make this more
- unlikely to happen. I'd check to see if somebody isn't shutting
- the system down properly...

- Change the gamma lines in /usr/lib/X11/xdm/{Xlogin,Xstartup}
- and /usr/bin/X11/X to look like this to help the situation some:
-
- glGammaFile=/etc/config/system.glGammaVal
- glGammaDefault="1.7"
- if [ -r $glGammaFile -a -s $glGammaFile ]; then
- glGammaVal=`cat $glGammaFile`
- else
- glGammaVal=$glGammaDefault
