The Nasty Battery Power Usage On Ubuntu 11.10
Collapse
X
-
Just tested my Llano laptop, usually holds around 4 hours in Windows 7 with the occasional Youtube video running, about 2 hours in Ubuntu.

Ha ha ha
And the ugly yet UNTRACED for over a year random freezes of Ubuntu and derivatives. I bet everyone is saying sorry to Squeeze now. He he he. Fix fonts in Debian like this:
The rumors are true. Installing Iceweasel 5 from http://mozilla.debian.net/ solves three problems that have plagued lots of Linux users:
1.Obsolete Iceweasel/Firefox.
2.Ugly font rendering with official Firefox binaries.
3.Ugly font rendering everywhere on the system.
You heard it right, folks. Installing Iceweasel 5 in Squeeze brings in a version of libcairo2
So do this:
Add the following entry to /etc/apt/sources.list or a new file in /etc/apt/sources.list.d/:
deb http://mozilla.debian.net/ squeeze-backports iceweasel-release
Add the archive key to your apt keyring:
# wget -O- -q http://mozilla.debian.net/archive.asc | gpg --import
Import it into the APT keyring:
# gpg --export -a 06C4AE2A | sudo apt-key add -
Update the repository database:
# apt-get update
Install Iceweasel 5 with the following command:
# apt-get install -t squeeze-backports iceweasel
If font still ugly add to the ~/.fonts.conf a file posted here:
Pastebin.com is the number one paste tool since 2002. Pastebin is a website where you can store text online for a set period of time.
and you're done.
For broadcom wifi use debian wiki.
Ha ha ubuntu shmoontu. Suck my ... Canonical.

the incredible thing is that kernel developers must be suffering this pain themselves, and they should rush to fix this, but, kernel versions and months pass, and the bug persists.

Sorry for the lag, tha backlight is at 25%
If interested here are two scripts i use; the first is for powersave, the second is for full performance.
acpi daemon switch between them when connected to the line.
I can't say if windows 7 can reach that values; sure xp should last 10.5hours according to asus specs.
But i can reach (idling all the time) even 10.9..11 hours, for what matters

Code:#!/bin/bash #ScreenBrightness # xbacklight -set 100 #sudo sh -c "echo 15 > /sys/devices/virtual/backlight/acpi_video0/brightness" sudo sh -c "echo 15 > /sys/class/backlight/acpi_video0/brightness" #cpufreq sudo cpufreq-set -c 0 -g performance sudo cpufreq-set -c 1 -g performance #eee-she performance sudo eee-she -p #standby del disco a 2ore 30min.

Ah, on my model there s a bug in the kernel on audio side; muting and unmuting the audio card saves an extra 0.4W (?!)
I switch manually until i write something to do via scripting:
amixer set Master mute
amixer set Master unmute
--
edit
just append this to the first script should work:
Code:mute=$(amixer get Master|grep "\[off\]") if [[ "$mute" ]]; then amixer set Master mute sleep 0.01 amixer set Master unmute sleep 0.01 amixer set Master mute else amixer set Master unmute sleep 0.01 amixer set Master mute sleep 0.01 amixer set Master unmute fi

of course Michael is going to post consumer issues about ubuntu. Isn't that the distro he uses?
also is the most widely used distro and many are based on it so they'll have the same problem.
Or maybe you want him to post issues with Slackware and get like 2 views? Who uses that?
So at least a comparaisson gnome/unity would be nice to assure that its not an effect of the gui.
Since the 10.4LTS uses gnome not unity.
That would also help the people working on the different projects to now if that's a bug in their Software.
also is the most widely used distro and many are based on it so they'll have the same problem.
And the most people wouldn't be affected if the problem lies in the Ubuntu kernel config and unity.

Personally, after doing that, i have 5,9 -> 6,1W in idle on a netbook with similar spec (asus 1005ha) with kernel 3.0.
Didn't test it under load.

It is not just Ubuntu that is going to suck more power, it is Linux. The changes are on the kernel side.
Geezzzzz....
Compile in the new kernel on an Arch Linux / <your favourite distro here> and test the power again.
Ubuntu bad, Ubuntu slower booting, Ubuntu Unity fail, Ubuntu unstable, Ubuntu own test suite (where is ours!), Ubuntu <negative rant here>
I, for one, love Unity. And its keyboard shortcuts. KDE is a good second but the <meta>+1 to switch between apps is brilliant. I am really productive on it, and apart from the terrible power management I'm actually looking forward to 11.10.
