ACER Aspire 4520 tried to kill me…….(2)

I started to work on this unit since September 2007, tried to pump the Linux in. I have tried to install many distros; the result was failed and failed again. I considered this as a trigger for m to keep pushing myself harder in knowing about Linux. I didn’t want myself just as a Linux installer, i wanted more.

I have tried to install PCLOS2007, Vector, DreamLinux, OpenSuse, Skole, Slackware, Mandriva, IGOS to this laptop. But…like usual, it kept rejecting them. The last; i returned to edubuntu-7.04 again. I asked questions to about my problem. Any Linux that i installed on can not display a good graphic (graphic card problem), can not connect to the wireless and it’s mute (sound problem).

One of edubuntu users told me that i have to force this unit to run in save graphical mode by doing;

edit /etc/X11/xorg.conf, go to the Device stanza for your video card and change the driver to vesa, eg:

Section “Device”

Identifier “ATI Technologies, Inc. ATI Default Card”
Driver “vesa”
BusID “PCI:3:0:0”


Then do sudo /etc/init.d/gdm restart

Actually, an alternative and possibly better way to do this is to run:

sudo dpkg-reconfigure xserver-xorg

You will be led through a series of menus. Take the default answer to all questions (there are quite a few), except where you are asked for the “X server driver”, when you should choose “vesa”. Once that’s done, try restarting the display manager

sudo /etc/init.d/gdm restart

yes, it worked….in safe graphic mode, but it didn’t satisfied me.

Two months passed by, slowly i found out the way to solve this problem. I used Ubuntu-7.10 ( Gutsy Gibbon ) and after searched for the answer at and waiting from edubuntu-users answers. I can settle it down.

Here is the way out;

How to set the display ( nVIDIA 7000M )

go to Applications – Add/Remove
type nvidia and choose : nvidia binary driver (‘new’ driver )
click on apply button and wait until the installation finished
go to system – Restricted Drivers Manager – enable the NVIDIA
open terminal
type sudo vi /etc/X11/xorg.conf
replace the resolution manually from “1024×768” to “1280×800”
reboot the computer

How to set the wireless ( Atheros – AR5007EG )

download the AR5007EG windriver
install ndiswrapper manually
open terminal; type sudo rmmod ath_pci ( remove the pci module )
type sudo vi /etc/modprobe.d/blacklist-common
insert : blacklist ath_pci ( to put ath_pci in blaklist mode )
save it and restart the computer
extract the windriver into one folder ( ex: documents )
go to System – Administration – Windows Wireless Drivers
install net521.inf
click configure button and set it up
open terminal; type sudo ndiswrapper -m ( to load ndis on restart )
reboot the computer

How to set the sound ( Realtek High Definition Audio a.k.a Realtek ALC268 )

install linux-backports-modules-
install linux-backports-modules-generic_2.6.22.14
open terminal; type sudo vi /etc/modprobe.d/alsa-base
insert : options snd-hda-intel model=acer
reboot the computer

By November 05, 2007, i finished my long journey to make ACER Aspire 4520 runs in Windows XP and Ubuntu Gutsy Gibbons, as an addition; this laptop was Vista design.. 😀




  1. Thanks a lot for ur help…got ubuntu running on my acer 4520.

  2. oh my friend thank you for this information. I wil try with my Acer 4520.

  3. I just cant setup the display on Acer 4520 (nVIDIA 7000M). Everytime I start Ubuntu it just stop its progress in the splash screen then afterwards initramfs appears. Its my first time to try Ubuntu. Could someone guide me? Thank you.

  4. did you encounter problem with network configuration. The eth device number is incrementing each time the laptop is rebooted.

  5. and fedora?
    i will try with my 4220
    thanks for yours tips.

  6. Hey.. thats a great collection of fixes for Ubutu 710 on Acer Aspire 4520. I was able to install it in the safe graphics ode and then got mot of the things working as mentioned in the post above only WiFi remaining, wil try that soon

    The only problem is with the Display. I a able to have it going into 1280×80 0 resolution with all 3D Effects working, but whenever I reboot, it keeps on going to 800×600 resolution and have to manually go and select the higher resolution. I am not able to find the entry in XORG.conf to mention the default resolution. Can somebody help me with this.???

  7. I have got the Solution for the Resolution problem… here it is

    1. Make sure the restricted driver is installed (in Synaptic search for nvidia-glx-new)
    2. Execute this command in a terminal:
    sudo dpkg-reconfigure -phigh xserver-xorg
    3. Open Restricted Drivers Manager and enable the nVidia driver.
    4. Reboot, and you should be good to go.

    Hope this helps..

  8. dear chadrich,
    -when you boot, select the first row, then press “e” to edit
    -add “all_generic_ide” at the end of the kernel line so become like this : kernel /boot/vmlinuz-2.6.22-14-generic root=UUID=8770f1df-2ede-4ede-8d79-649ecdf50456 ro quiet splash all_generic_ide
    -then press “b” to boot

    next, after you get to desktop,

    -open terminal
    -sudo gedit /boot/grub/menu.lst
    -change the kernel line just like above ( add “all_generic_ide” after splash word )
    – sudo reboot

    i think : your ubuntu will run smothly now……

  16. acer_acpi-0.11.1…did’t i require to install this to??

    I hav a Li1718 and I’ve got Wlan working.
    In Addition to the ndiwswrapper-module I downloaded acer_acpi
    (Please google for the Url I don’t have it available)
    compiled the module modprobe acer_acpi
    and then issued following command as root:
    echo 1 > /proc/acpi/acer/wireless
    The wlan-LED should turns on now and you should have a functioning and working wlan.

    coz my wireless didn’t blinking at all…

  17. no you dont have to…….
    what is the output of this :==> sudo lshw -short -C network

    g3ndi7@g3ndi7-ubuntu:~$ sudo lshw -short -C network
    [sudo] password for g3ndi7:
    H/W path Device Class Description
    /0/a eth0 network nVidia Corporation

  27. helo there…i dun know what happen,but suddenly my wireless can be used…yay….thanks for ur help….i’m really appreciate it…

  28. thanks friend.

    information on this post helped a lot.

  29. I have been through a lot trying to get this computer up and running with this acer 4520 laptop. I have tried to do everything on my own up to this point. My sound still is not working and I have tried to find and install the backport you have said but I cannot find it in my add/remove programs or the web. Can you tell me where to get this so that I can get my sound. That is the last thing left. I had trouble installing the wireless for a while but i did not have the 5211 .cat file in with the inf file so i struggled lol. I am such a nub. If you can help me I would be appreciative. thank you for your time.

  30. Thank you, thank you, thank you. YEAH!!!!!!! It works now. I am happy everything works. Man I am really glad there are people out there like you. I had my wifi up and running for a couple days now but it took me 2 weeks to figure out I needed the .cat file along side of the inf file. then it started working all of a sudden. but it was this page that I had printed out from windows to figure it out in linux after downloading a ton of things to make sure I had the right things. It has been one big headache. I got it now thanks to you.

  31. glad to know that….
