'''Kernel Boot Fix''' As of kernel 2.6.31-18, there have been problems relating to speed and the system intermittently freezing. By default, the NB 205 (and other related models such as the NB 200) sometimes freeze and suffer from low performance due to a power-saving feature of the Linux kernel. Dramatic speed increases have been noted with this feature disabled (boot speeds increased by 20 seconds). If you wish, this feature can be disabled. To disable the kernel feature (if using the GRUB2 bootloader), use a text editor as root to open the file: /etc/grub.d/10_linux Find the section near the top that looks as follows: {{{ save_default_entry | sed -e "s/^/\t/" prepare_grub_to_access_device ${GRUB_DEVICE_BOOT} | sed -e "s/^/\t/" cat << EOF linux ${rel_dirname}/${basename} root=${linux_root_device_thisversion} ro $2 }}} Add the following to the end of that last line: {{{nohz=off}}} ...so the full line reads: {{{linux ${rel_dirname}/${basename} root=${linux_root_device_thisversion} ro $2 nohz=off}}} Then run the following from the Terminal to complete the fix: {{{sudo update-grub}}} A reboot will be required to apply the change. '''Bootup time''' The boot time is with the default settings horrendously slow. A simple change in the BIOS will speed up the boot time to less than 30 seconds. * Press F2 on machine boot to enter the BIOS * Select the 'Advanced' tab * Change SATA controller mode from AHCI to Compatibility '''Bluetooth''' Bluetooth will not work with default, but again, simple change is necessary to get it to work. We need to configure the kernel module omnibook correctly. There are a few option, I currently use these: * create a new file in /etc/modprobe.d named omnibook.conf with content {{{options omnibook ectype=12}}} * force the module to be loaded at system start by editing /etc/modules and add {{{omnibook}}} at the end * to test the changes without reboot load the module manually {{{sudo modprobe -v omnibook}}} The bluetooth icon should appear in the task bar. ---- CategoryDocumentation |
Ubuntu Netbook Remix Post-Installation Help
The purpose of this guide is to enable Wifi, hibernate, and other features on the Toshiba NB205 that which do not work out of the box with Ubuntu Netbook Remix (UNR).
Wi-Fi
Wi-Fi must be enabled in Windows XP before installing UNR or else it is impossible to enable it. **Update** You can also enable your wifi by going into your BIOS setup at startup and enabling wifi.
From the main menu, go to Administration then Software Sources. In the Updates tab check "Unsupported updates (jaunty-backports)". After closing this window, Update Manager will likely ask you to allow it to check for updates, and you should do so. If it does not, issue in a terminal:
sudo aptitude update
...to retrieve new package lists.
After the package list update, from a console issue the following command to get Wi-Fi up and running.
sudo apt-get install linux-backports-modules-karmic
This will install a new Linux kernel (2.6.31-20-generic as of this update) which will be selectable from your boot loader upon restarting your computer.
Sound
To enable sound via headphone jack, use a text editor as root to add the following line to /etc/modprobe.d/alsa-base.conf:
options snd-hda-intel model=asus-mode4
Kernel Boot Fix
As of kernel 2.6.31-18, there have been problems relating to speed and the system intermittently freezing.

To disable the kernel feature (if using the GRUB2 bootloader), use a text editor as root to open the file: /etc/grub.d/10_linux
Find the section near the top that looks as follows:
save_default_entry | sed -e "s/^/\t/"
prepare_grub_to_access_device ${GRUB_DEVICE_BOOT} | sed -e "s/^/\t/"
cat << EOF
linux ${rel_dirname}/${basename} root=${linux_root_device_thisversion} ro $2Add the following to the end of that last line:
nohz=off
...so the full line reads:
linux ${rel_dirname}/${basename} root=${linux_root_device_thisversion} ro $2 nohz=off
Then run the following from the Terminal to complete the fix:
sudo update-grub
A reboot will be required to apply the change.
Bootup time
The boot time is with the default settings horrendously slow. A simple change in the BIOS will speed up the boot time to less than 30 seconds.
- Press F2 on machine boot to enter the BIOS
- Select the 'Advanced' tab
- Change SATA controller mode from AHCI to Compatibility
Bluetooth
Bluetooth will not work with default, but again, simple change is necessary to get it to work. We need to configure the kernel module omnibook correctly. There are a few option, I currently use these:
- create a new file in /etc/modprobe.d named omnibook.conf with content
options omnibook ectype=12
- force the module to be loaded at system start by editing /etc/modules and add
omnibook at the end
- to test the changes without reboot load the module manually
sudo modprobe -v omnibook
The bluetooth icon should appear in the task bar.
