This guide is intended to users from an Acer 4520, some variants of this model may work with the tips here, some may not.
I am writing this post from the installation until the setup of all hardware, or almost all hardware, since there are some things that we were not able to setup yet.
The intention is to keep upgrading the content of this post with tips from community.
The distribution used is the Ubuntu 7.10 32 Bits, and only this one, the 7.04, or 8.04, or any other may be different and the tips here may work or not.
I decided to install the 32 Bits version, 'cause I have to do so many workarounds in this version, that I can't have time enough to do the same in the 64 bits, plus another issues that the 64 bits version has. So I keep the 32 bits, although the tips here and many steps can be followed by 64 bits users.
Note: 64 Bits user look at this post from "afterstep13" http://ubuntuforums.org/showpost.php...39&postcount=5
I assume you have wired internet available, because to set up the wireless Internet we need it. I also believe you have a little bit of knowledge in Linux, not all the things are very well explained, my fault. BTW. As it is the first guide, I accept suggestions, and don't worry about my English, it's not my first language.
My Hardware Specs:
Acer 4520 - 5726 - AMD Turion 64 X2 Mobile TL-58 (1.9 Ghz, 2 x 512 L2 Cache)
Chipset Nvidia Nforce 610M
VGA - Nvidia GeForce 7000M - 14" WXGA+ WideScreen 1280x800
2GB DDR2 667 - 160 GB HDD - DVD-RW
Atheros AR5007EG 802.11b/g WLAN
Card Reader- Express Card Slot
S-Video e Monitor OUT
4 USB 2.0 - 1 Mini-Firewire (4 Pinos)
So let's start:
1) The BIOS Setup configuration
- Get to the BIOS, make sure you're using the AHCI mode in "Sata Mode" and put the CDROM as primary boot device.
2) Booting the Live-CD
- After choosing the language, if needed, choose "Start Ubuntu in safe graphics mode". And wait until gnome is loaded.
3) Normal Installation
- Do a normal installation, the problems will start happening later. Make sure your swap size is as big as your RAM size, otherwise you won't be able to hibernate sometimes.
4) Rebooting
- Here comes the problem, the system won't boot, so here are the steps:
In GRUB menu select the appropriate line, press "e" to edit the options, select the second line, the one beginning with "kernel" and append the "break=top" to the end, after editing press "enter" and then "b" to boot. After few seconds you'll fall into a shell frame, with "initramfs" written and a blinking cursor. Then type the following:
You'll boot normally after this. Some people typed to load other modules, but with these combination I got 100% of success.
5) Fix the boot issue
First thing is fixing the issue, there were many workarounds about this problem, the plausible solution was found in this thread http://ubuntuforums.org/showpost.php...&postcount=131 (thanks to "afterstep13"):
Still in gnome, with a low resolution, don't worry we'll fix the vga problem soon, create a script:
Add the following lines to its content:
Then make it executable with:
Update the initramfs:
Reboot, now it's going to boot normally, this script make a ten seconds delay, so it'll take 10 seconds before starting the boot process, anyhow it works very well, better waiting 10 seconds, than typing every time the commands from last step. Some tweaks make the boot process real faster in dual core processors, write about this later.
6) Wired LAN
Works out of the box*.
Incrementing eth# problem, look at this tip in this same thread http://ubuntuforums.org/showpost.php...39&postcount=5
7) Updates
Active the repositories needed, and update all the software, before tweaking the system. Updates may break some tweaks. This is a very important step. After updating, reboot.
8 ) Sound - High Definition Audio
You might be asking yourselves, why installing sound before video. I don't know why, but installing sound after the video may break nvida installation. ???? . So let's do the sound before the video. The solution is simple, downloading latest alsa drivers and compiling them. "Question: I've seen an alternative solution with ubuntu's "linux-backport-modules", isn't easier?". Actually, that solution is pretty quicker than this one, but with that one, the microphone was not working with me, so I compiled it myself.
This tip I got partially from https://help.ubuntu.com/community/HdaIntelSoundHowto. And also from another thread here in forums http://ubuntuforums.org/showthread.php?t=577699
I am passing all the process here, but at the end I have made some modifications in the script from this post http://ubuntuforums.org/showpost.php...2&postcount=13, and you may want to download to automate the process. Then you should run these steps.
Sound should be working, I used this script and worked very well.
Otherwise you may want to do it manually. With the following steps.
Install dependencies:
Alsa Driver, Lib and Utils:
Extracting them and removing tarballs:
Making the directory for compiling the source:
Compiling and installing alsa-driver
Compiling and installing alsa-libs
Compiling and installing alsa-utils
Reboot the machine and run more these comands:
Reboot once more. And the next time will have sound working, no extra tweaks needed, like adding some line to /etc/modprobe.d/alsa-base. The steps above must solve the problem with sound and mic. The mic will work after enabling all boxes in the Gnome mixer applet. Change the input source to "front mic" or "mic" depending on which microphone you are gonna use. That's it.
9) Wireless LAN - Atheros AR5007EG
Tried already the madwifi drivers, and ndiswrapper. After tested both of them, the one which best worked with me was the ndiswrapper compiled from source.
a) Download and compile ndiswrapper 1.52
b) Blacklist the native ath_pci module to prevent from loading it.
Add the line:
c) Download the xp driver from Atheros Site, look for the driver 6.0.3.85 for Windows XP 32 Bits, the file name will be xp32-6.0.3.85.zip. The file inside must be net5416.inf (not net5211.inf).
Extract and install it:
It must be working now with the led, if it doesn't, make sure it isn't off, or try a reboot.
d) Fixing the LED Problem
Wireless in Linux, it's never perfect. After comparing some .inf files, and many hit and tries. I've found a solution for the LED that's always on. The solution is quite simple, but it is necessary some attention in which files we should edit. First
Find which device is listed in ndiswrapper:
Mine device is listed on "168C:001C". The you go to /etc/ndiswrapper/net5416/, look for the files that begin with the exactly name of your device. You should edit a file with the name "XXXX:XXXX.5.conf". In my case, was:
The beggining of the file content should be like this:
Right below the line "gpioPinFunc1|3", you add the line:
Unload and load ndiswrapper:
Now your LED will act different, will blink each 5 seconds, and always on when connected, you can change de values, instead of 4, I tried 1,2,3 and I got different results in how the LED acts. You can test different values and see which one you will like the most. I'm in doubt in 3 or 4. hehehe
10) VGA - Nvidia
Finally installing the Graphics Card, I let it almost for last, because I don't know why but this driver is very sensitive to system changes, I tried to install at first, but installed the sound, messed nvidia, installed wireless, messed nvidia, so I let it for last. I found a better solution compiling the latest drivers from the Nvidia Website, just because the built-in driver "nvidia-glx-new" doesn't hibernate, no matter what you do. Some may want to install it using envy, your choice, but I read that it doesn't work very well. So I'm gonna do it myself:
a) Downloading the latest driver from Nvidia website. The latest IA32 version, not the legacy ones. Save all your job you're doing at the moment (we are going to stop Gdm). Go for a tty1 by pressing "Ctrl+Alt+F1". Login and type:
Go to place you donwloaded the Nvidia drivers and run the executable:
Say yes to all questions and restart the computer.
b) After restarting you'll still get the low resolution, so edit the xorg.conf and manually change the resolution.
Then change the resolution line in the "Section "Screen"":
It was:
And change to
I also disabled the logo feature by adding to this same section the line:
There has been some problem happening to users, that the title bars keep disappearing.
The fix is adding the following line to the Device Section also in xorg.conf
So, restart X (Ctrl+Alt+Backspace) and that's it. Your pretty gnome again. Troubles: NvidiaManual
11) Touchpad
It works out of the box, but you can tweak a little bit.
a) Backing up and editing xorg.conf:
Adding the line (Option "SHMConfig" "true") to Synaptics InputDevice Section, the whole section should look like this:
b) Installing the Gsynaptics to manage preferences for touchpad. Available in "System > Preferences > Touchpad"
c) Disabling touchpad while typing:
Put the command below in the start session of gnome, under "System > Preferences > Sessions > Add"
12) Webcam
Works out of the box. Program to manage 13) Card Reader
Not fully functional. I couldn't test all kind of cards. But Memory Stick doesn't work. I've read SD cards only work. You may want to check this project at BerliOS
14) Hibernate (Suspend to disk) and Standby (Suspend to RAM)
Should Work out of the box with latest Nvidia Drivers .Although hibernate fails sometimes. I tried with the VESA driver, it worked always. Nvidia driver problems.
So after googling a little bit, I found out about that option from xorg.conf, NvAgp, and it has many alternatives.
I added to xorg.conf in device section the following line, it's supposed to turn off agp support, nothing happened to my video anyway, but now hibernate works 90% of the times, the other 10% no reason.
The line:
now, when I resume from hibernate, the sound stops working, "working on it" :P
Suspends works with no problems.
15) S-Video and VGA Out
Both work perfectly with the Nvidia X Server Settings under "Application > System Tools > Nvidia X Server Settings). It's very easy to set up different displays. Detection works fine as well.
16) Dial-up Modem, Express Card and mini-firewire
None of them tested, anyone?
13)ACPI, Battery, Laptop Health and others
a) Install Powertop, a program to monitore the consumption from your laptop, should be ran with sudo
b)Decrease disk acess, and as consequence usage of battery. Two ways of doing it, you can use both, one of them or none, since the are problems for some people using them, read where this information was taken, all the discussion here http://ubuntuforums.org/showthread.php?t=107856
Changin the journal type to data=writeback (only ext3). this change the type of your filesystem journal, read more about it before doing this tweak
- Edit GRUB menu:
Find the entry from Ubuntu, and append "rootflags=data=writeback" at the end. Then the end of the line should look like this:
[code]kernel /boot/... ro quiet splash rootflags=data=writeback[code]
- Edit fstab
Append the data=writeback to the end of the line of your ext3 filesystem. Looking like this:
[code]... / ext3 defaults,errors=remount-ro,data=writeback
- Change the journal type:
Where X is the number of your ext3 partition.
- Check if everything is ok.
c) Change to noatime, it makes system stop updating the access time every time a file is accessed Warning: some programs may utilize this feature, it will improve the system speed but you may have side effects, read more about it before doing this tweak
- Edit fstab
Append notime to the ext3 partitions options:
d) Deacrese the interrupts from nvidia, see powertop before and after doing this, seek for nvidia, after doing this will disappear or will be at the bottom. (Experimental Power Saving Mode)
- Edit xorg.conf
- Add the line to the Device Section or the Screen Section, depending on your configuration:
e) Increase the Boot Speed by starting services in parallell mode. I haven't forgot what I promessed, after the 10 seconds delay you will have a faster boot after this tip, very noticeable with the dual core processors.
- Edit the file rc
- Look for a line "CONCURRENCY=none" and change to "CONCURRENCY=shell"
By doing this we'll have problems in simultaneuosly services. The service HAL must be delayed:
f) CPU Frequency Scaling Monitor
The is very useful for reducing the frequency when running on battery to save power.
- Add to the panel the applet located "CPU Frequency Scaling Monitor" under "System & Hardware".
- Run: (read all the warning, and if you are sure about this, say yes)
- If you say yes, restart the Panel or only the applet. And then you'll have four frequencies available to control.
g) Sensor - Temperature Monitoring
- Install the sensors daemon and applet:
- Then detect the sensors, you must say yes to all questions, run:
After rebooting, you can add the applet "Hardware Sensors Monitor" and see what components you want to monitore.

6) Wired LAN
Works out of the box*.

This tip I got partially from https://help.ubuntu.com/community/HdaIntelSoundHowto. And also from another thread here in forums http://ubuntuforums.org/showthread.php?t=577699
I am passing all the process here, but at the end I have made some modifications in the script from this post http://ubuntuforums.org/showpost.php...2&postcount=13, and you may want to download to automate the process. Then you should run these steps.
Code:
sudo sh alsa_1.sh
reboot
sudo sh alsa_2.sh
reboot
Otherwise you may want to do it manually. With the following steps.
Install dependencies:
Code:
apt-get install build-essential libncurses5-dev gettext linux-headers-`uname -r`
Code:
wget ftp://ftp.alsa-project.org/pub/driver/alsa-driver-1.0.16.tar.bz2

sudo cp -v /usr/src/alsa/alsa-driver*/modules/* /lib/modules/2.6.22-*/kernel/sound/
sudo depmod -a
9) Wireless LAN - Atheros AR5007EG
Tried already the madwifi drivers, and ndiswrapper. After tested both of them, the one which best worked with me was the ndiswrapper compiled from source.
a) Download and compile ndiswrapper 1.52
Code:
wget http://superb-west.dl.sourceforge.net/sourceforge/ndiswrapper/ndiswrapper-1.52.tar.gz
tar -zxvf ndiswrapper-1.5*
sudo mkdir -p /usr/src/ndiswrapper
sudo mv ndiswrapper-1.52/ /usr/src/ndiswrapper/
cd /usr/src/ndiswrapper/ndiswrapper-1.52/
sudo make uninstall
sudo make
sudo make install
Code:
sudo gedit /etc/modprobe.d/blacklist
Code:
blacklist ath_pci
Extract and install it:
Code:
unzip xp32-6.0.3.85.zip
sudo ndiswrapper -i net5416.inf
sudo ndiswrapper -l
sudo ndiswrapper -m
sudo ndiswrapper -ma
sudo loadndisdriver
sudo modprobe ndiswrapper
d) Fixing the LED Problem
Wireless in Linux, it's never perfect. After comparing some .inf files, and many hit and tries. I've found a solution for the LED that's always on. The solution is quite simple, but it is necessary some attention in which files we should edit. First
Find which device is listed in ndiswrapper:
Code:
$ndiswrapper -l
net5416 : driver installed
device (168C:001C) present (alternate driver: ath_pci)
Code:
sudo nano /etc/ndiswrapper/net5416/168C\:001C.5.conf
Code:
sys_files|ar5416.sys
NdisVersion|0x50001

10) VGA - Nvidia
Finally installing the Graphics Card, I let it almost for last, because I don't know why but this driver is very sensitive to system changes, I tried to install at first, but installed the sound, messed nvidia, installed wireless, messed nvidia, so I let it for last. I found a better solution compiling the latest drivers from the Nvidia Website, just because the built-in driver "nvidia-glx-new" doesn't hibernate, no matter what you do. Some may want to install it using envy, your choice, but I read that it doesn't work very well. So I'm gonna do it myself:
a) Downloading the latest driver from Nvidia website. The latest IA32 version, not the legacy ones. Save all your job you're doing at the moment (we are going to stop Gdm). Go for a tty1 by pressing "Ctrl+Alt+F1". Login and type:
Code:
sudo /etc/init.d/gdm stop
Code:
sudo sh NVIDIA-Linux-x86-*
b) After restarting you'll still get the low resolution, so edit the xorg.conf and manually change the resolution.
Code:
sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf_backup
sudo gedit /etc/X11/xorg.conf
It was:
Code:
Modes "800x600"
Code:
Modes "1280x800"
Code:
Option "NoLogo" "true"
The fix is adding the following line to the Device Section also in xorg.conf
Code:
Option “AddARGBGLXVisuals” “True”
11) Touchpad
It works out of the box, but you can tweak a little bit.
a) Backing up and editing xorg.conf:
Code:
sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf_backup2
sudo gedit /etc/X11/xorg.conf
Code:
Section "InputDevice"
Identifier "Synaptics Touchpad"
Driver "synaptics"
Option "SendCoreEvents" "true"
Option "Device" "/dev/psaux"
Option "Protocol" "auto-dev"
Option "HorizEdgeScroll" "0"
Option "SHMConfig" "true"
EndSection
Code:
sudo aptitude install gsynaptics
Put the command below in the start session of gnome, under "System > Preferences > Sessions > Add"
Code:
syndaemon -i 1 -d
Works out of the box. Program to manage
Code:
sudo aptitude install cheese
Not fully functional. I couldn't test all kind of cards. But Memory Stick doesn't work. I've read SD cards only work. You may want to check this project at BerliOS
14) Hibernate (Suspend to disk) and Standby (Suspend to RAM)
Should Work out of the box with latest Nvidia Drivers .Although hibernate fails sometimes. I tried with the VESA driver, it worked always. Nvidia driver problems.
So after googling a little bit, I found out about that option from xorg.conf, NvAgp, and it has many alternatives.
I added to xorg.conf in device section the following line, it's supposed to turn off agp support, nothing happened to my video anyway, but now hibernate works 90% of the times, the other 10% no reason.
The line:
Code:
Option "NvAgp" "0"
Suspends works with no problems.
15) S-Video and VGA Out
Both work perfectly with the Nvidia X Server Settings under "Application > System Tools > Nvidia X Server Settings). It's very easy to set up different displays. Detection works fine as well.
16) Dial-up Modem, Express Card and mini-firewire
None of them tested, anyone?
13)ACPI, Battery, Laptop Health and others
a) Install Powertop, a program to monitore the consumption from your laptop, should be ran with sudo
Code:
sudo aptitude install powertop
Changin the journal type to data=writeback (only ext3). this change the type of your filesystem journal, read more about it before doing this tweak
- Edit GRUB menu:
Code:
sudo gedit /boot/grub/menu.lst
[code]kernel /boot/... ro quiet splash rootflags=data=writeback[code]
- Edit fstab
Code:
sudo gedit /etc/fstab
[code]... / ext3 defaults,errors=remount-ro,data=writeback
- Change the journal type:
Code:
sudo tune2fs -o journal_data_writeback /dev/sdaX
- Check if everything is ok.
Code:
sudo tune2fs -l /dev/sdaX
- Edit fstab
Code:
sudo gedit /etc/fstab
Code:
... / ext3 defaults,errors=remount-ro,noatime,data=writeback
- Edit xorg.conf
