Opera 9.12-OPLC for linux

OPLC version of Opera rocks in my fedora core 8.
I'm amazed how opera improved over the years.
Not an opera fan but this version really rocks so far!

testing disk performance

Test disk read performance -
#/sbin/hdparm -t /dev/sda
/dev/sda:
Timing buffered disk reads: 62 MB in 3.09 seconds = 20.04 MB/sec

IPV6 disable and Konqueror speed improvement

There's a lot claim in the net that,
Konqueror by default tries IPV6 first then IPV4. Save time by disabling it.
With wireless connection, only works the following -
/etc/modprobe.d/blacklist
add the following line
blacklist ipv6

Also including "alias ipv6 off" in modprobe.conf and
#/sbin/chkconfig ip6tables off

improves speed!

My findings -
It didn't improve my speed at all, rather it made few web sites having problems!
So I would rather not stick with it.

rc.local for intel powertop

my powertop tweaks made changes in rc.local -

ethtool -s eth0 wol d
echo powersave > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor

no need if laptop-mode-tools active -
echo 1500 > /proc/sys/vm/dirty_writeback_centisecs
cause laptop-mode-tools set higher value than this.

echo 1 > /sys/module/snd_ac97_codec/parameters/power_save

Suggestion: Enable USB autosuspend by pressing the U key or adding
usbcore.autosuspend=1 to the kernel command line in the grub config

echo 1 > /sys/bus/usb/devices/usb1/power/autosuspend

setting up LBP1210 in Redhat FC8

Had a nightmare in getting my canon LBP1210 laser printer work with
cups in Fedora Core 8 -

Download the printer driver in following site-
http://software.canon-europe.com/products/0000525.asp

When using printer driver, Please check out followings -

1) SELinux mode

If SELinux is set to Enforce, Please try SELinux set to Permissive.
If you'ld like to use SELinux in Enforce mode, Please make the policy
package and install it.
There is the method of making a policy package in README-capt-1.6xE.txt.
(/usr/share/doc/cndrvcups-capt-1.60/README-capt-1.6xE.txt)

2) Register the printer entry

If the HAL daemon runs on Fedora Core, and if the printer entry is made
automaticaly, please register the printer entry again using the
following method.

(Please power on the printer and the USB cable connect to the PC.)

# /etc/init.d/ccpd stop

# /usr/sbin/lpadmin -x LASER_SHOT_LBP-1210
[the above line is not needed. Without that worked fine, but after
installing driver rpm just reboot the PC, also
#cngplp
to setup page size and save changes. thats all I did pretty much, I
have tried with changing toner density as well to save ink, that
worked too.]

# /usr/sbin/lpadmin -p LBP1210 -m CNCUPSLBP1210CAPTK.ppd -v
ccp:/var/ccpd/fifo0 -E
# /usr/sbin/ccpdadmin -p LBP1210 -o /dev/usb/lp0

# /etc/init.d/ccpd start

That should work!

Troubleshoots- cups doesnt start ccpd -
So heres the solution -
start cups and then start ccpd manually -
/etc/init.d/cups start
Try printing a doc - (ctrl+p)
/etc/init.d/ccpd start

Bingo works! I will suffice myself with this, when get time, will fix
cups start ccpd as well. For now it works for me.

Readers, leave a comment, if that worked for you or not.
