The thread I started and the other threads dealing with CF/MD/other
storage mediums have been quite informative. My question now is what
are ways to optimize battery life and number of writes to CF. One of my
z50s finally came this morning and I decided that this one is going to
run from a 512MB Transcend 25X CF memory card. When the other one comes
it will run from my 1GB Microdrive.
I added noatime and nodevmtime to fstab. Are soft updates a good or bad
thing in this situation? Does suspend/resume make any difference when
soft updates are enabled?
I have the following daily.conf to only have minimal writes:
# Add local overrides below
#
find_core=NO
expire_news=NO
purge_accounting=NO
run_msgs=NO
run_calendar=YES
check_uucp=NO
check_disks=YES
check_mailq=YES
check_network=YES
run_fsck=NO
run_rdist=NO
run_security=YES
run_skeyaudit=NO
And I have the following weekly.conf for the same reason:
# Add local overrides below
#
rebuild_locatedb=NO
As far as suspend and resume goes, is suspended state all that much
better on battery conservation? It doesn't seem like it goes into all
that "deep" of a suspend. I think the Microdrive was still spinning
although I couldn't tell for sure if it was the Microdrive or something
else. I recompiled the kernel with the LCD suspend option and now that
works fine.
I suspended the z50 while I was in X earlier today and when I brought
it back up several hours later I had eight or so vertical bars and I
couldn't get anything to respond. I had to do a reset by removing the
battery and power cord. Is this possibly symptomatic of me running
1.6.1_RC2 with X from 1.6? By the way, I am running the ion wm.
Thank you for your help. I appreciate the helpful attitude on the
NetBSD lists.
