HARDWARE LG C1
From Gentoo Linux Wiki
Contents |
[edit] General
Please notice that the network controller does not have a driver in the current kernel (2.6.22) and that the 2007.0 Gentoo CD's don't support the Intel PRO/Wireless LAN 3945abg network controller. So, you need to install Gentoo from the livecd.

| File: make.conf |
CFLAGS="-O2 -march=prescott -pipe -fomit-frame-pointer" |
[edit] Tablet
For enabling the tablet, you'll need to compile your kernel with the next modules (not compiled in kernel):
| File: Kernel modules for tablet |
Device Drivers --->
Character devices --->
Serial drivers --->
<M> 8250/16550 and compatible serial support
<M> 8250/16550 PCMCIA device support
(10) Maximum number of 8250/16550 serial ports
(10) Number of 8250/16550 serial ports to register at runtime
[*] Extended 8250/16550 serial driver options
|
If you are using kernel 2.6.23 and below (kernel 2.6.24 and above include this patch), before compiling kernel, you'll need to put the next patch:
| File: Patch the kernel |
|
Add the next 2 lines (marked with plus) to /usr/src/linux/drivers/serial/8250_pnp.c
/* Fujitsu Wacom Tablet PC devices */
{ "FUJ02E5", 0 },
{ "FUJ02E6", 0 },
+ /* LG C1 EXPRESS DUAL (C1-PB11A3) touch screen (actually a FUJ02E6 in disguise) */
+ { "LTS0001", 0 },
/* Rockwell's (PORALiNK) 33600 INT PNP */
{ "WCI0003", 0 },
/* Unkown PnP modems */
|
Then, compile your kernel and load modules 8250 & 8250_pnp:
| File: load modules for tablet |
# modprobe 8250 # modprobe 8250_pnp # echo "8250" >> /etc/modules.autoload.d/kernel-2.6 # echo "8250_pnp" >> /etc/modules.autoload.d/kernel-2.6 |
Now, you'll need to download http://stz-softwaretechnik.com/~ke/touchscreen/fujitouch-0.6.5.tar.gz. Extract it and copy fujitsu_drv.so to /usr/lib/xorg/modules/input & stylus to /etc/init.d/:
| File: configure the tablet driver |
# wget http://stz-softwaretechnik.com/~ke/touchscreen/fujitouch-0.6.5.tar.gz # tar -zxvf fujitouch-0.6.5.tar.gz # cp fujitouch-0.6.5/fujitsu_drv.so /usr/lib/xorg/modules/input/ # cp fujitouch-0.6.5/stylus /etc/init.d/ # /etc/init.d/stylus start && rc-update add default stylus |
Then, configure your xorg.conf and add the next lines:
| File: configure /etc/X11/xorg.conf |
Section "ServerLayout"
....
InputDevice "touchscreen" "SendCoreEvents"
EndSection
Section "InputDevice"
Identifier "touchscreen"
Driver "fujitsu"

Option "DeviceName" "touchscreen"
Option "MinX" "82"
Option "MinY" "146"
Option "MaxX" "4036"
Option "MaxY" "3999"
Option "SendCoreEvents" "On"
EndSection

[edit] Video
Relevant hardware:
- Video card: Intel 945GM
See also HARDWARE Intel 945G
- 10.6" XGA TFT screen (default resolution 1280 x 768)
915resolution package is needed for this resolution.
[edit] Console
For framebuffer support use the VESA VGA.
[edit] Xorg
Xorg works fine, just remember to config in make.conf:
| File: make.conf :: video cards and input devices |
VIDEO_CARDS="intel i810 i945 v4l vesa vga fbdev" INPUT_DEVICES="keyboard mouse wacom evdev synaptics" |
Some xorg.conf settings:
| File: xorg.conf :: Touchpad |
Section "InputDevice"
Identifier "Mouse1"
Driver "mouse"
Option "Protocol" "Auto" # Auto detect
Option "Device" "/dev/input/mice"

[edit] Brightness
For brightness switcher try those two scripts:
| File: /usr/bin/brightup |
#!/bin/sh
cur_bright=`cat /sys/class/backlight/acpi_video0/brightness`
max_bright=`cat /sys/class/backlight/acpi_video0/max_brightness`
if [ $cur_bright -lt $max_bright ]
then
cur_bright=$(( $cur_bright+1 ))
echo $cur_bright > /sys/class/backlight/acpi_video0/brightness
fi
echo "Brightness: " $cur_bright | osd_cat -p bottom -A center -c green -d 1 -f "-adobe-helvetica-bold-r-*-*-34-*-*-*-*-*-*-*"
|
| File: /usr/bin/brightdown |
#!/bin/sh
cur_bright=`cat /sys/class/backlight/acpi_video0/brightness`
if [ $cur_bright -gt 1 ]
then
cur_bright=$(( $cur_bright-1 ))
echo $cur_bright > /sys/class/backlight/acpi_video0/brightness
fi
echo "Brightness: " $cur_bright | osd_cat -p bottom -A center -c green -d 1 -f
|
Then, just add permissions (some on startup) for the brightness files:
| File: configured brightness |
# chgrp video /usr/bin/bright* # chmod g+x /usr/bin/bright* # echo "chgrp video /sys/class/backlight/acpi_video0/brightness" >> /etc/conf.d/local.start # echo "chmod g+w /sys/class/backlight/acpi_video0/brightness" >> /etc/conf.d/local.start |
Note 1: Only who member in the video group can change the brightness of screen.
Note 2: To assign key map for this two scripts try this guide.
Note 3: For those scripts output you'll need xosd package. just emerge it.
[edit] Audio
Relevant hardware:
- Multimedia audio controller: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller
The built-in sound card is a Intel High Definition Audio Controller. This is supported by the hda-intel driver in >=alsa-driver-1.0.14_rc1.
| File: /etc/make.conf |
ALSA_CARDS="hda-intel usb-audio" |
[edit] Volume buttons
Not tested yet.
[edit] Network controller
Relevant hardware:
- Ethernet controller: Agere Systems ET-131x PCI-E Ethernet Controller (rev 03)
This card works with the et131x driver, but this driver is not yet included with the kernel or portage. To get this driver you'll have to download the source from the Agere ET131x ethernet driver project [1] and compile it manualy.
If you are using 2.6.23 kernel, pay attention to this patch.
[edit] WiFi
Relevant hardware:
- Network controller: Intel Corporation PRO/Wireless 3945ABG Network Connection (rev 02)
See also HARDWARE ipw3945.
Make sure you have the right modules and options in your kernel, if not portage will complain.

[edit] Bluetooth
You need to follow this guide to make your bluetooth work.
[edit] Internet via Bluetooth connection
Just follow this guide, and then add this script to your init:
| File: Init script for internet via bluetooth (net.ppp0) |
#!/sbin/runscript
depend() {
after bluetooth
}
start() {
echo " Starting Bluetooth internet with ppp connection"
start-stop-daemon --start --background --exec /usr/bin/wvdial gprs
echo $! > /tmp/pid.ppp0
}
stop() {
echo " Ending Bluetooth internet with ppp connection"
start-stop-daemon --stop --exec /usr/bin/wvdial gprs
}
Then just run this command to make this file executable: # chmod u=+x /etc/init.d/net.ppp0 |
This works for me with Nokia E61.
[edit] Modem
The modem is supported by the hsfmodem. See this HowTo.
[edit] Lm Sensors
If you want lm sensors to work, just update your kernel:
| File: kernel configuration for lm sensors |
Device Drivers --->
--- I2C support --->
--- I2C support
<*> I2C device interface
I2C Hardware Bus support --->
<M> Intel 82801 (ICH)
Miscellaneous I2C Chip support --->
<M> EEPROM reader
<*> Hardware Monitoring support --->
<M> Intel Core (2) Duo/Solo temperature sensor
|
Compile and reboot to the new kernel. Only the new version of lm_sensors (2.10.3 and above) work with this chip (see also in their site). So unmask before installing it.
| File: Installing lm_sensors |
# echo ">=sys-apps/lm_sensors-2.10.3" >> /etc/portage/package.keywords # emerge -atv lm_sensors run the sensors initialized script # sensors-detect run the init script of lm sensors: # /etc/init.d/lm_sensors start run sensors to see details on your chip: # sensors if you want to run lm_sensors on boot: # rc-update add lm_sensors default |
