If the SuspendTime option is enabled, X will fail to start
indicating that it can not process the option. The other
power saving options (StandbyTime and OffTime) appear to
work. The README.S3 documents the SuspendTime option.
I am unable to find any reference to SuspendTime option in the
/usr/X11R6/lib/X11/doc/README.S3 file that is included in
XFree86-3.3.2 or XFree86-3.3.2.
Ooops, my mistake. The *Time options are documented in the man page
for XF86Config(5). The man page XF86_S3(1) refers to having to
specify the "power_saver" option in order to use the *Time options.
In addition, this used to work flawlessly in RHL 4.1 for i386.
What exact type of S3 chipset are you using? It also says in the
XF86-S3 man page:
The suspend level is currently only supported for the Mach64 and
for the 732, 764, 864, 868, 964, 968 S3 chips.
It also states that it is considered experimental so it could be
possible that your card is not yet fully stable.
Please feel free to reopen this bug once you have obtained the
necessary information requested.
