You should return your laptop. The key seems to be defective. But if
you think that's borked wait until you install linux on it. The nuts here
will tell you that it's perfect but that couldn't be further from the truth.
The guy who wrote the article already listed a dozen things that won't work
right. Besides that linux is so inefficient that it will suck the life out
of your battery. The author even mentions that simply moving the mouse
cursor causes CPU usage to jump 10%. Trying playing a mp3 file and it'll
bury your CPU.

Linux is worth exactly what you paid for it. Nothing.

[Quote from the article]

Conclusion:
Although the touchpad generates a lot of interrupts, under XP this does not
translate to much increased CPU usage, or much increased power usage.

Under Ubuntu, moving the mouse using the touchpad took over 10% of the CPU.

Micoshaft corporation's pista drains more batteries more
quickly and runs slower.

Nice article... goes into some serious setup details. The one that caught my
eye was this:


1. echo 1500 > /proc/sys/vm/dirty_writeback_centisecs
2. iwpriv eth1 set_power 2
3. hciconfig hci0 down && rmmod hci_usb
4. echo 5 > /proc/sys/vm/laptop_mode
5. echo
performance> /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
6. echo 1500 > /proc/sys/vm/dirty_writeback_centisecs
7. echo 3 > /sys/class/backlight/sony/brightness
8. #
9. ethtool -s eth0 wol d
10. #
11. hdparm -B 1 -S 35 /dev/sda
12. echo 0 > /sys/devices/platform/sony-laptop/bluetoothpower
13. #echo 0 > /sys/devices/platform/sony-laptop/cdpower
14. echo 0 > /sys/devices/platform/sony-laptop/fanspeed
15. hal-disable-polling --device /dev/scd0
16. xset s 120 120


Under his title "Using powertop and maximising battery life" at the line
numbered "5" he sets up the scaling_governor with "performance". Surely
this is a misstake? That forces the laptop to CONSTANTLY run at maximum cpu
frequency...EVEN if it's doing nothing. What the idiot should have done was
used the "ondemand" governor. Which cuts the processor frequency to the
minimu when doing nothing and scaling up as the user load builds.

Does wonders for my COMPAQ PRESARIO R3000.

That one error is his setup, makes the whole linux evaluation suspect. It's
like claiming you tuned your car for maximum gas milage, but the whole
time the accelerator pedal is strapped down to the floorboard. Stupid...
and then have the audacity to complain about it!!

Personally, I think this would be a good move. Anytime you trade windows for
something else, you win. Imagine... no more defrag, virus check, reboot
after every single update, etc. Not to mention the hundreds of free
applications...

Hundreds? The number of '*.ebuild' entries in my Gentoo
Portage tree numbers in the tens of thousands last
I looked. Granted, each of those is a version, not a
separate application.

$ find /usr/portage -name '*.ebuild' | wc -l
24742
$

It's a lot.

True enough... But... in my humble defense, hundreds means multiple
hundreds... easily reaching into the thousands.

Cheers.

Nice save. :-) Still, I think any piece of code worth
porting will eventually end up on both Windows and Linux --
and generally work more reliably on Linux.

The battery life shouldn't be too much of a problem. According to the
article, the laptop consumes 15% more power in full idle when running
Linux than it does when running Windows. Given that most sleeping
Windows machines can sit in standby mode for several hours, even a
full day - I wouldn't get terribly freaked about it.

If you are doing long flights, you might want to get an external
battery. APC makes one for about $80 that can run a T40 for 8 hours
on a single charge.

> > DO YOU GUYS THINK THIS WILL WORK WELL FOR ME?

It looks pretty good to me. I liked that the WiFi worked better on
Linux than for Windows XP. It doesn't look like there is a 3D OpenGL
(GLX or XGL) accelerator option though.

This may be a function of how idle time is measured, and how display
time is accounted for.

On Windows, Idle time is measured by running The System Idle process
and comparing it with other running processes. The GDI and other
display functions are kernel functions and excluded from the total.

On Linux, the kernel measures the idle time as those times when there
was literally nothing to do. Furthermore, the X11 display and several
other applications waiting for interrupts are running as application
processes which are always guaranteed at least some run time and can
be triggered by any related interrupt such as h-sync interrupts (used
to sync X-server displays in 3D animations)..

If the Video card supports Direct X, it will probably perform better
on XP. If it supports OpenGL, it will probably run better on Linux.
If it supports Neither, then 2D will run better on Linux and 3D will
probably run better on Windows.

It was amusing that your link featured 4 links to ways to "Fix your
XP", one for fixing the USB driver (had that problem for 4 years - USB
2 port would only function as USB 1.1 port),
Fix Boot failures (nice to have with you at all times - never know
when a virus or Microsoft security patch might render your PC
unbootable). And something to fix out of date drivers for XP, another
one that is a "must have". I wonder how much the set would cost -
they don't spell the costs out up front, and I'm not interested in
digging for it.

Article states,

At first I thought that Ubuntu was much slower than windows on
booting up but impressions can be deceiving. Windows does a good
job of showing you your desktop as fast as it can but you can't
actually use it for a fair bit longer, and launching firefox asap
incurs a huge delay, evidently because certain services are still
being started up in the background.

This XP install is fairly vanilla. No AV software or anything
expensive put into auto-startup. Most of the stuff Sony threw in
was removed or disabled.

Ubuntu is up and multi-user earlier than XP, at about the 25
second mark after grub kicks it off, but takes longer to give you
a fully functional desktop. Once the desktop appears, however,
the machine is pretty much devoted to your needs so it is able to
start firefox in just 5 seconds or so.

In both XP and Ubuntu, the wifi network is up and available
before you are able to use it.
