- 5 Troubleshooting
Nvidia's Closed-Source Driver
Just install the official closed source drivers from arch extra repo:
pacman -S nvidia
pacman -S xf86-video-nouveau
And (highly experimental) 3D support:
pacman -S nouveau-dri
Here, you have two options: either install rtl8192 package from AUR or use ndiswrapper with Windows 2000 driver for the card. The latter seems to be much snappier (better wifi range) but disables the use of aircrack.
Native linux driver
For native linux drivers you need to load r8192se_pci module:
You can add r8192se_pci to your MODULES array in /etc/rc.conf, though udev should load them automatically.
Ndiswrapper and W2K driver
Detailed ndiswrapper installation instructions coming up soon.
In order to use the function keys and extend battery life, you can set up the ACPI Driver, then install and configure the tools below.
The driver for the ACPI functions of the 1201N is called eeepc_laptop. It is part of the mainline kernel, so all that needs to be done is to load the module:
If the command fails with such error message:
FATAL: Error inserting eeepc_laptop (/lib/modules/2.6.32-ARCH/kernel/drivers/platform/x86/eeepc-laptop.ko): No such device
you need to add acpi_osi=Linux to kernel parameters in your bootloader configuration.
You must have acpid installed to use the Function keys:
pacman -S acpid
After installing acpid, you will have to add it to your DAEMONS array in rc.conf.
Then, you need to install acpi-eeepc-generic package from AUR and edit file /etc/conf.d/acpi-eeepc-generic.conf:
Comment out EEEPC_CONF_DONE option:
If you are using linux drivers for wifi you should also edit the WIFI_DRIVERS array:
Otherwise the wifi toggle button won't work.
Afterward, you must restart acipd:
Power Management with Laptop Mode Tools
You can use Laptop Mode to substantially increase your battery life on Linux. To do so, Install the [Laptop Mode Tools|laptop-mode-tools] from extra repo:
pacman -S laptop-mode-tools
and add "laptop-mode" to your DAEMONS array in rc.conf. Many of the power managment settings in laptop-mode are disbaled by default, so it is encouraged that you explore the configuration files throroughly. Here are some highlights of configuration options worth exploring:
Super Hybrid Engine
Super Hybrid Engine is a simple FSB tweaker that can radically reduce power consumption.
To enable automatic SHE manipulation just edit /etc/laptop-mode/conf.d/eeepc-superhe.conf:
If you've configured function keys using acpi-eeepc-generic, you can manually change SHE mode by using Fn+Space.
Wifi Power Management
The linux-native wifi driver supports wifi power management. If you are using the linux-native wifi driver, you can enable basic power management by editing /etc/laptop-mode/conf.d/wireless-power.conf:
pacman -S pm-utils
If you are using linux wifi driver you need to unload it before suspending otherwise the machine won't resume. To do this automatically uncomment and edit appropriate line in /etc/pm/config.d/config file:
The ehci_hcd module is responsible for usb hub. Removing it solves the immediate resume issue (see Troubleshooting) You can try out the suspend2ram either by using function key Fn+F1 (if you've configured them to use pm-utils in /etc/conf.d/acpi-eeepc-generic.conf) or by running:
To enable LCD brightness automatic manipulation you need to edit /etc/laptop-mode/conf.d/lcd-brightness.conf and set proper BRIGHTNESS_OUTPUT path:
BATT_BRIGHTNESS_COMMAND="echo 8" LM_AC_BRIGHTNESS_COMMAND="echo 15" NOLM_AC_BRIGHTNESS_COMMAND="echo 15" BRIGHTNESS_OUTPUT="/proc/acpi/video/IGPU/LCDD/brightness"
The Intel Atom 330 does not support cpufrequtils in any reasonable way, so it is not recommended that you use cpufrequtils. You can disable it in /etc/laptop-mode/conf.d/cpufreq.conf:
Because the Atom uses so little power anyway, controlling the FSB using the "SuperHybrid Engine" should provide significant gain in battery life without the need for CPU scaling.
Most likely you are using kernel 2.6.32 or newer. The only solution for now is to downgrade to 2.6.31.
Machine does not resume after suspend2ram
You have to unload r8192se_pci module right before suspending. See Suspend2RAM section of this article for details.
After suspending the machine immediately resumes
You have to unload usb module(s) before suspending. See Suspend2RAM section of this article for details.
