fedora linux in aspire 4520

(sorry, i dunno how to slow it down)

gnome sensors applet 1.8.1
http://sensors-applet.sourceforge.net/




















make sure you have install gnome-applet-sensors , lm_sensors, libsensors3, hddtemp (for monitoring harddisk) via yum.

to enable hddtemp recognized our harddisk, you need to change this file /etc/sysconfig/hddtemp

# hddtemp(8) daemon options. # Add at least the disk(s) you want to monitor here.

HDDTEMP_OPTIONS="/dev/sda"
#HDDTEMP_DAEMON_OPTIONS="-l 127.0.0.1"
HDDTEMP_DAEMON_OPTIONS="-d"

then, try restart hddtemp with '/etc/init.d/hddtemp restart' in terminal

nvidia GPU always show '-233 ° C',sorry because i don't know how to fix this yet :P

there is no official release files for uvcvideo, i only find it via svn, so based on this instructions u need to enter this command to install it.

1. open terminal (lets say you already have a folder name linuxzip in ~/linuxzip)

[planet@fedorasal linuxzip]$ svn checkout svn://svn.berlios.de/linux-uvc/linux-uvc/trunk
A trunk/uvc_ctrl.c
A trunk/uvc_queue.c
A trunk/uvc_video.c
A trunk/uvc_v4l2.c
A trunk/uvc_compat.h
A trunk/uvc_driver.c
A trunk/uvcvideo.h
A trunk/Makefile
Checked out revision 125.
[planet@fedorasal linuxzip]$

2. then
[planet@fedorasal linuxzip]$ cd trunk/
3. type make and lastly make install (as root)

[planet@fedorasal trunk]$ make
Building USB Video Class driver...

4. currently i only know that ekiga work with acer webcam, i doesn' t know if it work with others apps yet.

ekiga 2.0.9 preferences

one of the commenter john perez asked me about sound system in fedora 7, actually i have same problem like him, i can't have sound in mplayer when i view youtube video, but if i closed youtube website, i can play mplayer, the problem is i can't have multiple sound like before, i have to turn off another application that use sound system, anyway i found the solution to fixed this bug, from here..
linuxquestions.org - multi application sound
1.just copy this code to /etc/asound.conf (as root)

pcm.!default {
    type plug
    slave.pcm "swmixer"
}

pcm.swmixer {
    type dmix
    ipc_key 1234
    slave {
            pcm "hw:0,0"
            period_time 0
            period_size 1024
            buffer_size 4096
            rate 44100
    }
}
ctl.swmixer {
type hw
card 0
}

credit to dive
save it, and restart alsa sound with this command

/etc/init.d/alsasound restart

if u cant restart it, just relogout/ login again. then you can have sound system(minimize/bell) / audacious / youtube website playing sound together.

personally, i choose this laptop because i can decided either to included windows or not , but i want to run fedora 7 instead linpus os. so here is my exprience with acer aspire 4520.
please note that my fedora 7 actually clone installation from desktop pc, i doing rsync to clone whole linux partition from my old desktop into this nice laptop.. : )

Atheros AR5006EG or AR5007EG
Generally, atheros support under linux via madwifi package, but it take me 4 days to figure out that this card doesn't work in linux yet...silly me, i does'nt read the last line in compatible list... lol but i believe maybe if you try to compile your own kernel without 4k stack, it might be run successfully

Chip:	wi-fi.org says that is AR5006EG
Supports:	IEEE 802.11b, 802.11g
Notes:	Dosen't work at all.
Notes:	DevID 0428
Notes:	In windows it's appears like AR5007EG
Notes:	.inf file information

.inf file in windows:
%ATHER.DeviceDesc.3067%  = ATHER_DEV_04281468.ndi, PCI\VEN_168C&DEV_001C&SUBSYS_04281468 //References to this Device, Look  ATHER_DEV_04281468.ndi ,an curiosity look DeviceDesc, = 3067
...
[ATHER_DEV_04281468.ndi.NT]  //more parameters referencing this device
Characteristics = 0x84 ; NCF_PHYSICAL | NCF_HAS_UI
BusType         = 5
DelReg          = 5211.DelReg
AddReg          = 5211.reg, ATHER.reg, 5211.reg, 5212.abgmp.reg, customer3a.reg, ATHER_DEV_04281468.ID.REG
CopyFiles       = ATHER.CopyFiles.nt, DEFAULTDESTDIRS
DelFiles        = ATHER.DelIniFiles
//and the end of file we have
ATHER.DeviceDesc.3067  = "Atheros AR5007EG Wireless Network Adapter" // look that DeviceDesc.3067 references to  AR5007EG.!!????

Notes:	It's returns Hal status 13, and sometimes hal status 3
Notes:	In Openhal the interface ath0 show up there aren't any communication, the commands like iwlist return error.
Notes:	Suported by ndiswrapper ver 1.47 (use tarball package) with windows xp driver.
Notes:	In Fedora 7, crash (kernel panic) when try to load ndiswrapper (modprobe ndiswrapper)
Notes:	Crash because default kernel limit stack to 4k. Need to recompile kernel with CONFIG_4KSTACKS disabled.

madwifi compatible list)

Acer Webcam CrystalEye webcam
currently this webcam run successfully in ekiga and cheese. You need to install uvc driver as kernel module, please note that this driver implements as V4L2, so if you got webcam apps, set it as v4l2 driver.
http://linux-uvc.berlios.de/#download

you should see this message after install this driver.
[root@fedorasal]# dmesg | grep uvc

it seems like realtek HDA, so i grab source from here choose the Unix(Linux) > Others = Version 4.06b

wget ftp://202.65.194.212/pc/audio/realtek-linux-audiopack-4.06b.tar.bz2
tar -xvf realtek-linux-audiopack-4.06b.tar.bz2
cd realtek-linux-audiopack-4.06/

unpack alsa-driver-rt20070820.tar.bz2(use file-roller or command)
download realtek12.tar.gz (67.5kb) from here https://bugtrack.alsa-project.org/alsa-bug/view.php?id=3104
patch this driver by overwrite into this folder
alsa-driver-rt20070820/pci/hda

then pack it back as alsa-driver-rt20070820.tar.bz2 , just use file-roller in gnome by right-click

this will fixed silent bug

run sh install.sh

then add the following lines in

/etc/modprobe.conf

options snd-hda-intel model=toshiba

restart or modprobe snd-hda-intel
thats all for now, sorry for my poor english. actually this is my first blog :P
