excessive X server start time
Hello,
For some time I have been trying to track down why I cannot get XDM
to start correctly at boot [1] under Sarge, where the system was
working properly under Woody. I believe XDM is giving up waiting for
the X server to start. Measuring the X server start time with "time X"
and closing the resulting display as soon as it comes up gives a real
elapsed time of 3 minutes 4 seconds.
So X does work, StartX does work also, And XDM does work, because I can
drive my external X termial with it.
Examining the output of "strace &>X.log -ff X" [2] indicates that it takes
over a minute for the X server to determine that it should use the clgen
driver (measuered from the start to when that selection is written to
the XFree86.0.log file).
Searching the XDM man page, I found the config
DisplayManager.DISPLAY.openTimeout
which is the amount of time for the XDM to wait for the display to be
available. I am going to see if that fixes this problem. If so, this
might be a FAQ item?
According to the man page, the openTimeout value is 30 seconds. I am
going to increase this to 255 and see if it makes a difference.
It is interesting that X takes so much longer to start under Sarge than
it had under Woody, as least on my Amiga 2000 with 030 at 40MHz and 16M
RAM with an EGS Spectrum (clgen) video card. My kernel is a 2.4.30
compiled off current CVS sources with the clgen support compiled in.
Once running, though, I have no issues with the response time. I seem to
recall that X under Woody went to 4.3.0 of the X Window System.
