I've just started setting up Linux on my new Acer laptop. All the usual disclaimers apply: this is just my own experience with one setup on one machine. No guarantees that it won't destroy anything or result in data loss if you try it on yours.
This model is a dual-core AMD E350 chip with Radeo Hd 6310 graphics. I have Debian installed and am using it to create this page. Here's a list of features I care about and current status.
|X Windows graphics||AMD/ATI Radeon HD 6310||Y|
|Wireless Lan||Atheros AR9287||Y|
|Wired Ethernet||Atheros PCI 1969:1083||Y|
|SD/MMC slot||Realtek USB 0bda:0138||Y*|
|Monitoring (Battery, temperature, etc)||Partial|
I'm using a Debian Unstable AMD64 installation disk that I downloaded March 18,2011. I tried Debian Stable, but the installer did not find the Ethernet device; it would load the wireless drivers, but I did not figure out how to activate the wireless network. Unstable still did not find Ethernet but it did automatically enable the wireless, so I was able to complete the install.
Wireless network is working fine. The only problem is the enable/disable hotkey(Fn-F3). Pressing this hotkey combination will shut off the wireless, but pressing it again does not enable it. I need to power-down the PC and restart to re-enable.
ifup wlan0 and
ifdown wlan0 do work. The little antenna LED
goes on and off as expected. Turning off with the hotkey and back on with
Using the Debian drivers, the LCD panel comes up in 1024x768 mode instead of the native 1366x768 mode, and resolution cannot be changed. The HDMI output is a copy of the LCD display. If an external VGA monitor is connected a power-up, the external monitor is used instead of the LCD panel. I was not able to switch between LCD and external monitor.
Things work a lot better with the AMD driver. I found a post at
forums.amd.com/forum/messageview.cfm?catid=390&threadid=145785 that explains how to get
the driver and install it (see the post by fmuelle2 01/26/2011 10:44 PM). That post led to
ati-driver-installer-11-2-x86.x86_64.run on the AMD website: Go to
support.amd.com, in the
Download Drivers box select
Desktop Graphics ⇒ Radeon HD Series ⇒ Radeon HD 6xxx Series PCIe ⇒ Linux x86_64.
With the AMD binary blob driver, the LCD panel comes up in native 1366x768 resolution,
xrandr shows multiple possible resolutions, and it also shows
CRT1 as disconnected devices. The supplied
aticonfig program prints 619 lines of possible settings to try. Essential functions
are working now; I'll play with those settings in my spare time.
May 2011: I upgraded to the
2.6.38-2-amd64 Linux kernel, and had to update to
11-5 version of the ati driver: 11-2 and 11-4 wouldn't compile with the new kernel.
Using aticonfig I was able to set up dual-head operation using an external monitor connected to the HDMI
output: the HDMI monitor becomes a second screen that is effectively a continuation of the laptop's
screen, so I can slide back and forth between them using the mouse.
The Debian kernel includes the
atl1e driver, but it does not find the ethernet device.
Source code for another driver is available at
partner.atheros.com/Drivers.aspx. I downloaded
AR81Family-linux-v18.104.22.168.tar.gz, did a
make install as root,
and it creates and installs a new version of the
atl1e driver, overwriting the one supplied
with the Debian kernel package. (You will need the
appropriate Debian packages for building kernel modules -
sudo ifconfig -a shows that
eth0 exists, and it can be set up normally.
May 2011: the driver in the
2.6.38-2-amd64 Linux kernel seems to work ok, so probably
don't need to install the replacement driver.
The camera works using the Debian out-of-the-box setup with no tweaking. It shows up in the list of USB
devices as "1.3M WebCam" by "XPACJ1PLG" Vendor=0402 ProdID=9665. I used the command
mplayer tv:// to display the camera output.
Two sound devices show up in
/proc/asound: card0 is the HDMI bus and card1 is the analog
audio (speakers, microphone, etc). I haven't tried card0. Card1 follows the new HD audio standard:
/proc/asound/card1/codec#0 it reports a
Conexant CX20584 codec
and seems to support only sampling rates of 44100 Hz and above. Based on info at
www.kernel.org/doc/Documentation/sound/alsa/HD-Audio.txt I downloaded
hda-analyzer (www.alsa-project.org/main/index.php/HDA_Analyzer and was able to see the various functions
of the device. As of now, I can get sound to play through the left channel only, and
sound only comes through the built-in speakers, even when headphones are plugged in. Still
working on getting the settings right, but at least it's showing signs of life.
Update April 2013: Audio is working within the limitations of the hardware.
arecord -vv -c 2 -f S16_LE -r 44100 /tmp/x.wav. Record functionality needs to be turned on: using
alsamixer, hit the space bar when the "Capture" slider is selected.
/proc/asound/card1/codec#0contains a line:
Pin-ctls: 0x40: OUTwhich changes to
0x00when headphones are plugged in. Similarly, there's a line
0x1a* 0x1b 0x1d 0x1ewhich changes to
0x1a 0x1b* 0x1d 0x1ewhen an external microphone is plugged in. (Thanks to unix.stackexchange.com/questions/25776/detecting-headphone-connection-disconnection-in-linux for pointing me in the right direction.)
CAUTION: There is a standard-size SD/MMC slot on the front below the keyboard. It shows up as a USB
device with VendorID:ProductID 0bda:0138. It works, except that it doesn't seem to detect
insertion and removal of a memory card correctly. I was able to work around the problem by
forcing Linux to reread the partition table for the memory card. These things worked for me, but
I can think of several things that could go wrong. For example, if you remove the SD/MMC card
and insert another one without rereading the partition table, if might be possible to trash
the contents of the card. If you are willing to risk the loss of data, you might want to try
The first workaround that I found is to unload and reload the kernel module (as root):
modprobe usb_storage# Corrected 5/30/2011.
mount /dev/sdb1 /my-mount-point
dmesgto see what happened.
Later, I found that it's possible to just tell Linux to re-read the partition table on the device. There are at least 3 possible ways to do that, so you can try one of these instead of the rmmod/modprobe command sequence.
hdparm -z /dev/sdb
partprobe /dev/sdb# Part of the
partedpackage on Debian.
blockdev --rereadpt /dev/sdb
/dev/sdb1should exist), (3) mount. When done, I (4)umount the partition, (5) remove the card, (6) try to reread the partition table: the read fails and therefore the
I used /dev/sdb as the device name in these examples, so /dev/sdb1 is the corresponding
mountable partition. It might actually come up as sdc, sdd, etc. On my system, there is a symlink
*** looks like
the serial number of the card reader). This symlink which currently points
/dev/sdb so that looks like the easiest way to figure out what device to use in the

When running the
acpi -V command shows battery status, Adapter 0 status (whatever that is),
and Cooling device status. When I was running the
2.6.32-5-amd64 kernel it would
also show the CPU temperature, but that seems to be broken in the current kernel.
April 2013 Temperature update: the
sensors-detect command from the
lm-sensors package finds
AMD Family 12h and 14h thermal sensors... Success! (driver `k10temp')
sensors command prints some temperature info. Not sure what it's measuring, though.
