I have the Acer Aspire 5742Z and tried Ubuntu 11.04 and Mint 14 as live distros. Can I expect the wireless LAN to work with the live distros? It works fine under the Windows 7 presently installed (that is, when I can boot it - at the moment I have always to boot to the last good start point!)

MB, 2013/01/15 19:26

Might try Ubuntu 12.04, but I don't recall if the liveCD works with the wifi. The auto-detected broadcom driver works once it's installed though.

Chris Clarke, 2013/01/15 21:17

Wifi now working from live CD - I am currently using the 5742Z with Mint 14 from live CD right now. I started to install Mint 14 but aborted because it didn't seem to be able to automatically resize the Win7 partitions, possibly because I think I chose the 32-bit live distro. But en-route it wanted to establish internet connection and so it took me through the authentication process.

Problem solved!

Get rid of windows completely. Totally. Delete all your partitions. Install Mint 14 download from linux site. Go with the flow. It's too easy! I'm a devotee. After 20 plus years of being fucked over by windows I now have a laptop that does not keep trying to tell me what it will or won't do. Windows?? Never again. Difficult?? My 12 year old daughter doesn't think so. Good Luck

rick, 2013/04/18 08:45

I finally spat the dummy with Windows (any version) and got rid of it completely.Linux. Mint 14. Too easy. Never been so happy. Not a single hiccup in about 8 months (so far). I'm loving it.

Brightness can be fixed with the help of google, I have an Acer Aspire 5742 intel i5-480m 6GB ram intelHD graphics, running on ubuntu 12.10 the only issues are only a LEFT speaker, and brightness which is now fixed, wireless and all have been tested long term and are supported, and as i speak my system's uptime since last power off is 3 days 8 hours. no freezing nothing.

As for the speaker, no solution besides mixing both sounds into a mono output which sounds horrible.

Liam Joseph Mania, 2012/10/31 06:41

Also, brightness CAN be controlled in windows…

James Greer, 2012/06/10 19:28

I have the Acer Aspire 5742 regular red version with the i3 2.4ghz and Intel HD 4gb ddr3 ram. It was refurbished when I bought it so not all other original parts may be there. So far Linux Mint 13 (Maya) Cinamon x64 has ran well on some ends not so great on others.
Had to reinstall due to wifi card failure and repaired it.
There is little to no OpenGL support as many games run slolwwww…
Several applications have crashed my wifi or desktop
It fixed and remapped 3-4 of my bad sectors out of 92 on my hdd :) Wierd but cool.
Think I should try Ubuntu 11.04 or Fedora 15?

MB, 2012/06/10 21:24

12.04 is doing really well on mine, it's my daily use work laptop.

charles, 2012/04/23 00:22

I tried to used that command on terminal but it does not work I have an acer 5742 and ubuntu 11.10 I've been trying to fix the brightness problem but nothing works
When I type the command sudo gedit/ect/default/grub nothing happens ._.

tiko, 2011/12/06 00:23

i have acer 5742g i5 64bits and i installed fedora16, but wireless doesn`t work! what is the problem?

data, 2012/01/04 17:35

No problems with Fedora 16 (x86_64) on Acer 5742Z-P622G32Mnss.

ali fraz, 2011/12/03 14:45

i am running redhat and lan is not detected ……..
kindly share solutions…..

simon, 2011/08/02 19:24

I've the Intel® Core™ i5-460M Mobile Processor (3MB Intel® Smart Cache, 2.53GHz)

Acer Aspire 5742 is working all fine with Ubuntu 11.04.

My gpu is intel HD with about 2gbs.

PS. I'm using fluxbox and it's all working fastly!!!!

Paul Grant, 2011/05/09 13:14


Please can anyone tell me if this laptop provides VT-x on its Intel processors? I need to be able to run KVM on it otherwise there's no point in buying one.



MB, 2011/05/09 14:56

I think it depends on which one you have. I have the model with the P6100, and it does not support the hardware virtualization. Runs Virtualbox fine, as long as it is emulating 32bit hosts.

The Core i5/i3 models should - but I can't confirm that.

Roger, 2011/04/13 15:21

Interesting. This is what is missing for me. I can control the brightness by hardware (fn+left/right) but the OS is not aware of it at all.

Does your version of Ubuntu also detect the temperature?

What kernel are you using?

MB, 2011/04/13 15:33


No, no temp. The proc thermal directory isn't even there, and acpi -t returns nothing.

Roger, 2011/04/13 16:45

Thanks. I should try a newer kernel (I'm on 2.6.37) to see if that solves the brightness problem at least. Too bad about the temperature sensors though.

MB, 2011/04/12 23:10

I have the 5742z, running 11.04 Ubuntu/Ubuntu Studio 64 bit.

So far, everything worked really well - brightness buttons, sound, sleep, WiFi, SD Card. It's a really excellent linux box.

robert, 2011/04/13 08:19

Sounds like I need to upgrade. My Ubuntu 10.10 dosn't seem to work very well.

MB, 2011/04/13 14:51

For some reason 11.04 (normal) 64 bit beta had some weird screen issues. They aren't in the Ubuntu Studio 64 version, so it could have to do with the new Ubuntu gnome shell replacement.

Roger, 2011/04/13 14:15

Is the brightness hardware or software controlled?

MB, 2011/04/13 14:49

It's a fn+left/right arrow key sort of thing. The on screen notification comes up, and the screen brightness changes.

Doesn't seem to be as massive a change as under Windows, but it is perceptible.

Roger, 2011/03/19 14:16

I have the following problems under Slackware with

1. hardware brightness control works with ” acpi_osi=Lnux” boot option, but no software control of brightness is possible
2. no cpu temperature measurements in /proc/acpi or anywhere else
3. sound only from left speaker, I wonder if there is only a single speaker in the computer?

Rahul Kumar, 2011/04/25 13:50

Ya Its a mono speaker system

Robert Metcalf, 2011/01/23 22:07

I have the Acer Aspire 5742 500Gb hd, 4Gb DDR3 Memory with the i5-460M processor.

It came with Windows 7. When I bought it I made the recovery disks then wiped the hard disk and installed ubuntu 10.10 64bit. I then installed virtual box and did a windows 7 restore from the disks. This worked fine.

Without any fixes I have had a few problems with ubuntu:
Sound - Only the left speaker plays sound. The mic does work
Wireless network - It works until the computer goes into sleep mode. At this point it won't work again until there is a reboot
Brightness control - Doesn’t work. When I press it once the screen goes blank and stays blank until another key is pressed. After I have done this the network stops working. I have tried the fix charlie mentioned but this caused no change in behaviour.

I still need to test:
HDMI Output (Sound and Vid)
Turning wireless on and off

Chris Chapman, 2011/10/28 22:50

For the wireless, does the icon just disappear from your Ubuntu panel? If so, type the following into a terminal window:
This will bring the icon back. It's annoying, I know, but you just have to live with it I think. I don't think there's a patch currently for it.

charlie, 2011/01/10 01:40

I am currently running Ubuntu 10.10 on the Acer Aspire 5742z-4097.

Got the brightness control to work, but no power management yet. You can change the brightness, but you don't get the notification, which is somewhat ok I guess. I found the fix for the brightness here:

(the fix itself if you just want to get it over with)
Here is the solution that worked on my Aspire 5740; In the terminal, run:

sudo gedit /etc/default/grub

when the file opens, look for the line similar to:


and add “acpi_osi=” to the list, without the quotes, so it looks like:

GRUB_CMDLINE_LINUX_DEFAULT=“quite splash acpi_osi=”

save the file, then exit gedit. Next, be sure to run:

sudo update-grub

to make the changes permanent. Exit the terminal and reboot.

The above fix says it works on Travelmate 5740, but I have verified it does work on Aspire 5742.

ActionParsnip, 2011/02/06 17:40

gksudo gedit /etc/default/grub

sudo is NOT to be used with GUI apps.
