Linux++:::: Fedora 10 and Lenovo S10: a perfect 10

Finally. I had in my hands a netbook, Lenovo S10 to be precise.

Let's see. The netbook itself is pretty sleek (thanks abdza for mentioning about it in his blog last year). I got myself a black one.

The keyboard needs some adjusting to; ie tab key, right shift key, tilde and numerical keys (since the layout has shifted compared to what I'm used to on my HP nx8200). Those with large hands/fingers, better buy your selves an external (rollable) keyboard!

The netbook came with XP, but that didn't last long :P I only booted to XP once, to see how it fared.

Then, I booted to Fedora 10 with a USB external DVD drive and started installation.

Initial boot up after install was a bit longish, what with all the default services. In the end, I only enabled these services:

 [root@mine kdie]# chkconfig |grep 5:on
 acpid           0:off   1:off   2:on    3:on    4:on    5:on    6:off
 cpuspeed        0:off   1:on    2:on    3:on    4:on    5:on    6:off
 crond           0:off   1:off   2:on    3:on    4:on    5:on    6:off
 haldaemon       0:off   1:off   2:off   3:on    4:on    5:on    6:off
 iptables        0:off   1:off   2:on    3:on    4:on    5:on    6:off
 irqbalance      0:off   1:off   2:off   3:on    4:on    5:on    6:off 
 messagebus      0:off   1:off   2:on    3:off   4:on    5:on    6:off
 microcode_ctl   0:off   1:off   2:on    3:on    4:on    5:on    6:off
 rsyslog         0:off   1:off   2:on    3:on    4:on    5:on    6:off
 sshd            0:off   1:off   2:on    3:on    4:on    5:on    6:off
 udev-post       0:off   1:on    2:on    3:on    4:on    5:on    6:off

When booting without rhgb and quiet, I saw "Could not detect stabilization, waiting 10 seconds" message. To cut this 10 seconds, create a new initrd image:

 mkinitrd -f /boot/newimg.img kernel-version

and change grub.conf

With these setup, it took about 35 seconds from grub menu to kdm/gdm greeting screen. Pity I didn't record the XP boot time.

Key mappings such as brightness setting (Fn Arrow up/down), audio (Fn arrow left/right), camera (Fn Esc) and wireless (either the dedicated button or Fn F5) works out of the box. So do power management features such as suspend, hibernate and resume.

Getting longer battery life was the next step. Ran powertop and a little googling and put the recommendations to rc.local. Here's mine:

 echo ondemand > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
 echo ondemand > /sys/devices/system/cpu/cpu1/cpufreq/scaling_governor
 cat /sys/devices/system/cpu/cpu0/cpufreq/ondemand/sampling_rate_max > /sys/devices/system/cpu/cpu0/cpufreq/ondemand/sampling_rate

 echo 1500 > /proc/sys/vm/dirty_writeback_centisecs
 echo 20 > /proc/sys/vm/dirty_ratio
 echo 10 > /proc/sys/vm/dirty_background_ratio

 echo 1 > /sys/devices/system/cpu/sched_smt_power_savings
 echo 10 > /sys/module/snd_hda_intel/parameters/power_save
 echo 5 > /proc/sys/vm/laptop_mode

 #Decrease power usage of USB while idle
 [ -w /sys/bus/usb/devices/1-5/power/level ] && echo auto > /sys/bus/usb/devices/1-5/power/level
 [ -w /sys/bus/usb/devices/5-5/power/level ] && echo auto > /sys/bus/usb/devices/5-5/power/level

Battery lasted 3.5 hours, give or take. That's with wireless on.

Wireless didn't work out of the box. However, with a yum -y install broadcom-wl (from rpmfusion.org), and a reboot, we have connection. That simple.

My Huawei e220 modem works ootb. Real plug and play at work. Connecting to the net via bluetooth using my mobile phone works too.

Now, determining the window manager - which should I use? I tried lxde, xfce, kde and fluxbox. In the end, I think i'll make use of kde4 and fluxbox, with more time on fluxbox. Any WM would work, methinks. KDE4 is still snappy, however the RAM usage is a bit higher compared to when i'm using fluxbox (with kde apps such as konsole, klipper, guidance-power-manager, basket, etc).


Starting oowriter the first time was snappy too, took about 20 seconds. The next start took less time ~ 5-7 seconds.

All in all, Fedora 10 runs well on Lenovo S10. Not much tinkering required to run it. The netbook itself is useful for coding, surfing, troubleshooting on the go. If you want to run linux on a netbook, get S10.

ondemand v userspace

Thanks for the netbook performance tips. I've got an eee 1000 coming soon and I'm going to put Fedora 10 on it first thing.

I have a question about setting the cpu speed. If you enable ondemand, shouldn't you then disable the cpuspeed service?

Fn F5 does not work for me

I've got an S10e and could not get
Fn F5 for selective de/activating of
Bluetooth/Wifi working ?

Any Tipps ?
Does it really works on your System, not only the "green Buttun" ?

Sys: S10e with Opensuse11.1 Kernel 2.6.27 and up

greetings Bernd

used to

it used to work. However, it doesn't anymore after I flashed the new BIOS :(

I read about an older Bios where it
worked - mine is the original and not
the newest.
I reinstalled the SLED to Test the FnF5
and it worked - but not fully, it worked exact like the Green Radio Buttun, not seperatly switching of BT/WIFI.

So this dosn't solve my Problem.

My new Wificard is disturbed by working BT - so i have to switch bt off when WIFIing - only the FnF5 Switch works to solve this ( in XP ).

Greetings Bernd

bios version

I flashed to the latest s10e bios. that's when fn-f5 don't work anymore.

I have no problem using wifi when bt is turned on.

And yeah, was hoping for separate switches for bt and wifi.
