Currently running kernel: sys-kernel/vanilla-sources v126.96.36.199
I'll put everything else behind the cut because it'll take up a few pages... Hardware assay
- CPU: Intel Centrino Duo T7500 running at 2.20GHz x2
- Memory: 2GB
- Chipset: Intel ICH8M
- Video: nVidia GeForce 8400M GS, 256MB video memory on-board. Using the closed-source nVidia drivers from Portage (x11-drivers/nvidia-drivers) with full acceleration. Haven't tried VGA or TV-out yet.
- SATA: Intel 82801HBM/HEM (ICH8M) chipset, using in-kernel drivers (CONFIG_ATA_PIIX)
- IDE: Intel 82801HBM/HEM (ICH8M) chipset, using in-kernel drivers (CONFIG_BLK_DEV_PIIX)
- Ethernet: Broadcom BCM4401-B0, using in-kernel drivers (CONFIG_B44)
- Wireless networking: Intel Corporation PRO/Wireless 3945ABG (using the drivers contributed to the kernel tree by Intel (CONFIG_IWL3945))
- USB: Intel Corporation 82801 UHCI, EHCI, using the in-kernel drivers
- Sound: Intel ICH8 HD Audio, using the in-kernel drivers
- Firewire: Ricoh R5C832 IEEE 1394 Controller, using the in-kernel drivers
- SD card reader: Ricoh R5C843 MMC Host controller, R5C592 Memory Stick Bus Host Adapter, xD-Picture Card Controller using the in-kernel drivers (CONFIG_MMC_BLOCK, CONFIG_MMC_BLOCK_BOUNCE, CONFIG_SDIO_UART, CONFIG_MMC_SDHCI, CONFIG_MMC_RICOH_MMC)
- Wireless networking: Since v2.6.24 of the Linux kernel, you don't need to use the net-wireless/iwlwifi ebuild to supply the drivers. Un-install them and enable the modules in the kernel source tree. Please note that you will still need Intel's firmware (net-wireless/iwl3945-ucode) for them to work. I find that they work just as well.
- The NetworkManager subsystem works so long as you completely delete the links for your network interfaces from the /etc/init.d directory. Also, ensure that the /etc/wpa_supplicant/wpa_supplicant.conf file's ctrl_interface line has the value /var/run/wpa_supplicant/wlan0 - this is a glitch in NetworkManager that I've yet to contribute a fix for.
- v2.6.24 of the Linux kernel also includes the latest stable ALSA sound drivers, so if you have the media-sound/alsa-driver ebuild installed, remove it. Enable the ALSA drivers in the kernel and use the Intel HD sound drivers (CONFIG_SND_HDA_INTEL).
- I've installed the Synaptics touchpad drivers (x11-drivers/synaptics and gnome-extra/gsynaptics) and turned off everything that annoys me (like tap-dragging along the edges). No problems.
- One thing that annoys me a little is that a key (usually 'w') will stick every once in a while. I suspect that it's a console driver in the kernel that I really don't need, and will get shaken out soon.
- If you let the udev service load your drivers at boot-time, chances are it'll mess with your wireless configuration and give you two interfaces, wlan0_rename and wlan0. While not harmful, this will throw any network configuration system into a tizzy. What you want to do is edit the /etc/modprobe.d/blacklist file and add the line blacklist iwl3945 at the very end. Create a file /etc/modules.d/iwl3945 containing only the line options iwl3945 disable_hw_scan=1. As the root user, run the update-modules utility. What this will do is prevent udev from loading the driver module just because it found it and cause an explicit driver load a few seconds later into the boot process, which will make the wlan0 network interface do the right thing. It's confusing and annoying and should be done automagically but it isn't.
