I am using FreeBSD 2.2.1 distributed by Walnut Creek.
After installation using the original CD, X Windows functions properly.
But when I have rebuilt the kernel using the original GENERIC come with the
distribution and use that kernel, X Windows can only start properly for
once.
That means, X Windows can start and function properly just after reboot. If
I quit the X Windows and start again, the display becomes unreadable. But
the machine is not hanged anyway. It accept the key strokes
ctrl+alt+backspace to kill the X Windows but the system doesn't returns to
text mode but still unreadable. Even I can key in the shutdown command to
shutdown the system and the screen keep on showing unreadable content after
reboot. (Even I boot DOS after the error) The only remedy is to reset the
whole system.
Actually, I discovered the problem when I rebuilt a custom kernel for my
machine. I derived the system configuration from GENERIC. I have only
removed all the redundant drivers which are not applicable to my machine.
When I have discovered the problem, I tried GENERIC and found the same
problem.
So the question is what is the different between GENERIC and the
configuration file used to build the kernel came with Walnut Creek's CD?
Or it there any different between the source code used to build the
original kernel and on the CD?
During the testing, I have only booted the system using different kernel
and haven't changed any other configuration.
I am using S3 Trio64V+ (i.e. 86C765). But it doesn't seems to be the
problem of the display card as it works nearly perfect using the kernel
came with the CD.
Is there anybody can help and suggest solutions/remedies?
Thank you very much in advance.
