I installed Gentoo with X precompiled on the Dell Laditude D531 laptop. This obscure laptop needs a firmware update on multiple components that I will not do.

This craptop has speakers of unknown nature. I did intensive googling but no luck. I don't know what speakers this laptop has. I tried doing all drivers for sound enabled, but sound never came out of the speakers. I have no idea what driver these speakers use.

I installed Gentoo on this laptop with the r8188eu driver. But when I did the kernel configuration, the TP-LINK vendor or the r8188eu driver was nowhere to be seen. (I'm on ethernet right now, but I want this laptop to be portable.) [SOLVED] I used DHCPCD with iwconfig.

Another and last issue is the touchpad does not work. I tried enabling all synaptics options with INPUT_DEVICES="evdev synaptics" in my make.conf file. (Yes, I have evdev and synaptics installed.) I'm using my external USB mouse instead.

Any help is appreciated.

Oh, I guess you can't see the full .config because it exceeded the limit of the post.

In the next post, I will do the wgetpaste method.

If you want to tell me what to enable/disable, please tell me where it is in the menuconfig--NOT the .config.

roboto, could you edit your first post and remove the kernel configuration (now unnecessary), please?

It is easy to provide the configuration in the format CONFIG_FOO_BAR (cf. "Kernel configuration shorthand notation" ).

N.B: The Wiki articles about Linux may be interesting.

Did you check if the components of your Dell Laditude D531 work when booted from sysresccd?

roboto,

We need your lspci and lsusb output too. Knowing that you have a Dell Laditude D531 is not useful.

menuconfig has a search. Press / and enter a part of the thing you are looking for.
Symbol names work really well. In the event that the symbol is hidden because something it depends on is off, press z and search again.
z is a hidden symbols on/off toggle.
The search will succeed and you can read the help on the option you want. Pay attention to the Depends on: That expression must evaluate to true before you can select the option you really want.
In some cases, you may need to apply this recursively.

I've tried running the test Dell offers, but they are in the .exe format. I tried booting FreeDOS with this, but the output after executing the test file was: Error: Missing ROM device, exiting. Or something like that. I don't remember. I did this a few months ago.

roboto,

Your wifi is one of these. The kernel knows it by its Vendor and Device IDs.
Code:
  idVendor           0x0bda Realtek Semiconductor Corp.
  idProduct          0x8179 RTL8188EUS 802.11n Wireless Network Adapter

lsusb, looks them up in a database to give you a friendly name.

grepping the kernel sources
Code:
/usr/src/linux $ grep -R  0x8179
shows a few hits.
Code:
drivers/staging/rtl8188eu/os_dep/usb_intf.c:   {USB_DEVICE(USB_VENDER_ID_REALTEK, 0x8179)}, /* 8188EUS */

looks promising.

The option you need is CONFIG_R8188EU
The dependn on is
Code:
Depends on: STAGING [=y] && WLAN [=y] && USB [=y] && CFG80211 [=y]
so you need all those symbols on to be able to see the prompt
Code:
< >   Realtek RTL8188EU Wireless LAN NIC driver
in menuconfig.
Build the driver as a module. It will need firmware.

Ok... the interface is up... but what application besides net-setup do I use for connecting to the ESSID of my network?

roboto,

That's the hard bit done. Well done.

You need wpa-suplicant to deal with the wifi specific parts of a wifi link.
Once that's done its stuff and you are both authenticated and associated, the normal wired things apply.

You may have at most one tool driving wpa-supplicant. Problems from here on are usuallly different tools trying to set the wireless interface up.

Oh no, not again. I remember using this application back when I was using Arch. It was a huge pain to use.

This time, my /etc/wpa_supplicant.conf:

Code:
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=wheel
network={
    ssid="home"
    scan_ssid=1
    key_mgmt=WPA-PSK
    psk="very secret passphrase"
}


I can't execute the wpa_supplicant command because the command doesn't exist on my system.

Any help is appreciated.

P.S. I tried wpa_cli, but the output was this:

Code:
wpa_cli v2.6
Copyright (c) 2004-2016, Jouni Malinen <j@w1.fi> and contributors

This software may be distributed under the terms of the BSD license.
See README for more details.



Interactive mode

Could not connect to wpa_supplicant: (nil) - re-trying



And then it just hangs there.

I typed
Code:
wpa_cli status

Failed to connect to non-global ctrl_ifname: (nil)  error: No such file or directory

Is there *any* way I could port net-setup to my Portage tree?

wpa_supplicat is one of the packages to be installed before first reboot. In case you forgot to emerge it you may temporarily use ethernet and emerge it.

For configuration put only the bare minimum as shown in https://wiki.gentoo.org/wiki/Wpa_supplicant#Global and then use the graphical interface wpa_gui which itself would create the network={ } blocks.

Make up your mind whether to use Network management using DHCPCD or use the die hard Gentoo .net scripts approach (Handbook).

roboto,

All the pretty front ends to wireless network control and the not so pretty ones, like net-setup use wpa-supplicant to deal with the wifi crypto.
If you don't want to encrypt your wifi link you might be able to use wireless-tools.
'Might' because wireless-tools is obsolete and needs at least one hidden kernel symbol that is only turned on by selecting older wifi interfaces.

There is no need no interact with wpa-supplicant yourself, beyond setting up the its config file.
If you use open-rc network control scripts, it will do it. If you use NetworkManager, it will do it.

Problems arise when you try several methods, maybe without realising it. wpa-supplicant does what it was told to do last. When there are several callers, the interface cycles.
You will see that in dmesg. You may have at most one tool calling wpa-supplicant.

I successfully connected to my local ESSID with DHCPCD and iwconfig.

Any way I could find out about the sound drivers the unknown internal gfx card uses?

Never mind... I found an article that I've never seen before while googling intensively: http://en.community.dell.com/support-forums/laptop/f/3519/t/19425401

Should the driver be a module?

I searched for the driver in the menuconfig... it's nowhere to be found.

The audio driver? Then check your output of lspci
Code:
# lspci -nn | grep -i audio
and it should show you a line having something like [8086:27d8]

Then check https://www.startpage.com/do/search?query=%22808627d8%22+site%3Acateee.net replacing 808627d8 with what you have.

roboto,


Your wifi is either unencrypted or uses WEP. WEP is almost as good as unencrypted.
As long as you add your own security over the WiFi it will be mostly OK.
Wardrivers can still steal your bandwidth.

For your sound, you have a
Code:
00:14.2 Audio device [0403]: Advanced Micro Devices, Inc. [AMD/ATI] SBx00 Azalia (Intel HDA) [1002:4383]
   Subsystem: Dell SBx00 Azalia (Intel HDA) [1028:0206]

That's SND_HDA_INTEL in the kernel.
It will work as a module or as a built in. Its in two parts. The SND_HDA_INTEL part looks after the PCI interface.
You also need your codec, which is on a submenu. Its safe to include all the codecs. You can prune them back later, once you know the codec you need.

Some obscure SND_HDA_INTEL cards need module parameters too. Its easier to pass parameters at module load time than it is at kernel load time, as trial and error is easy.
Start off with SND_HDA_INTEL as a module.

One strange thing... on firefox, I have all the youtube codecs enabled in youtube.com/html5. But when I play a video, no sound comes out. I have Pulseaudio support for firefox.

I maxed out the volume in all bars on this soundcard with alsamixer. Still no sound.

Any help is appreciated. I have SND_HDA_INTEL with all of its dependencies enabled in the .config.

Code:
emerge --info | grep ^ALSA_CARDS
ALSA_CARDS="ali5451 als4000 atiixp atiixp-modem bt87x ca0106 cmipci emu10k1x ens1370 ens1371 es1938 es1968 fm801 hda-intel intel8x0 intel8x0m maestro3 trident usb-audio via82xx via82xx-modem ymfpci"
