This post summarize all the required steps to setup a operational GNU/Linux on a Dell Vostro 3460. After being a Fedora user during many years, I switched to Debian Wheezy to avoid the systemd
philosophy (but I was also highly influenced by Pinpin).
Installation media preparation
First of all, copy the DVD1 into an USB stick :
# cat debian.iso > /dev/sdX # sync
After a boot from this support, proceed with the classical installation, including the “Laptop” packages.
Energy saving bug
In the current kernel version (3.2.32-1) the power savings mechanism of Ivy Bridge platform is affected by a bug which leads to a random complete system freeze, more especially while using Firefox.
To get rid of this, the power savings mechanism can be disabled [1]. In /etc/default/grub
, set the following :
GRUB_CMDLINE_LINUX_DEFAULT="quiet i915.i915_enable_rc6=0"
Then re-install grub with update-grub
.
This bug was corrected in more recent kernel versions.
Drivers installation
Once installed from scratch, the kernel does not detect neither the ethernet controller (Atheros AR813x), nor the WiFi chip (Dell 1704 / Broadcom 43142).
The WiFi driver is available here. Before installation, dkms must be installed from the ISO file (stored on an other partition for example) :
# mount -t iso9660 /path/to/debian-wheezy-DI-b3-amd64-DVD-1.iso /media/cdrom # apt-cdrom add # apt-get install dkms # dpkg -i /path/to/wireless-bcm43142-dkms_<version>_amd64.deb
The alx driver for the ethernet card is available here. The installation must be done as documented in the project homepage :
tar xvf compat-wireless-2012-05-10-p.tar.bz2 cd compat-wireless-2012-05-10-p/ ./scripts/driver-select alx make && make install modprobe alx
The touchpad is detected as aPS/2 mouse by default. In fact this is an ALPS touchpad :
# tpconfig Found Synaptics Touchpad. Firmware: 8.96 (multiple-byte mode).
The driver version 1.0 corrects the detection issue. To install it [2] :
# mv psmouse-alps-dst-1.0 /usr/src # cd /usr/src # dkms build psmouse/alps-dst-1.0 # dkms install psmouse/alps-dst-1.0 # rmmod psmouse && sudo modprobe -v psmouse
Since september 2013, update the CPU microcode on boot is also recommended [3] :
# apt-get install iucode-tool intel-microcode
Apt repositories configuration
Since the sources list was not completed during installation, edit the /etc/apt/sources.list
to add the closest repositories :
deb http://ftp.fr.debian.org/debian/ wheezy main contrib non-free deb http://ftp.fr.debian.org/debian/ wheezy-updates main
and comment the entry added by the apt-cdrom add
:
# deb cdrom:[Debian GNU/Linux wheezy-DI-b3 _Wheezy_ - Official Snapshot amd64 DVD Binary-1 20121012-12:02]/ wheezy contrib main
Then, add te source for the source for the WiFi driver.
Miscellaneous
Flash is included in the flashplugin-nonfree package and the official JRE must be declared via alternatives
:
# update-alternatives --install /usr/bin/java java /usr/java/jre1.7.0_09/bin/java 1 # update-alternatives --config java
For Gnome 3, shortcuts can be added in the applications list with alacarte
or in any repertory with gnome-desktop-item-edit.
The *slightly* too thick title bar can be reduced to a decent size with :
sed -i "/title_vertical_pad/s/value=\"[0-9]\{1,2\}\"/value=\"0\"/g" /usr/share/themes/Adwaita/metacity-1/metacity-theme-3.xml
To mount filesystems via ssh, Fuse is the best solution, especially for video playing with VLC. It can be installed with :
# apt-get gvfs-fuse sshfs fuse-utils # adduser <username> fuse
In the same domain, usbmount
is required to mount external HDDs via USB with ntfs-3g
.
By default, the firefox theme is poorly suited to Gnome 3, but this can be adjusted by disabling the menu bar, and by enabling the dedicated theme with an extension to disable title bar [4].
Finally, to avoid bips during completion with the tabulation key, uncomment set bell-style none
in /etc/inputrc
and add set vb
in the file ~/.vimrc.
Power management and temperature
The graphics chip sleep mode (i915.i915_enable_rc6) is available only from the current unstable kernel (3.8.13). To install it, add the unstable repo in /etc/apt/sources.list :
deb http://ftp.fr.debian.org/debian/ unstable main
Then lock system upgrade from unstable by modifying its priority with the file /etc/apt/preferences :
Package: * Pin: release o=Debian,a=unstable Pin-Priority: 102
The kernel can be installed :
# apt-get -t unstable install linux-image-3.8-2-amd64
Compatible drivers are available for WiFi and touchpad (the install is done the same way than for previous kernel versions).
At this point, the power saving options can be enabled in /etc/default/grub :
GRUB_CMDLINE_LINUX_DEFAULT="quiet i915.i915_enable_rc6=3 i915.i915_enable_fbc=1 i915.lvds_downclock=1 pcie_aspm=force acpi_osi=Linux"
Followed by a grub update for application :
# update-grub
The CPU scaling governor can also be set to conservative via cpufrequtils
to limit the CPU frequency [5]. Temperature monitoring can me done with the i8kctl temp
command, provided in the i8kutils
package.
Finally, the kernel module for SD card reader can be disabled (it makes a lot of cpu events), and power saving mode for the audio chipset can be forced. In a new /etc/modprobe.d/power_savings.conf file, set :
blacklist rts5139 options snd-hda-intel power_save=5 options snd-hda-intel power_save_controller=Y
And to prevent powerd
to overwrite this settings, disable the corresponding module via the /etc/pm/config.d/modules configuration file :
HOOK_BLACKLIST="intel-audio-powersave"
H264 hardware acceleration
To enable the MPEG2 and H.264 decoding by the graphics chipset, install the packages libva-intel-vaapi-driver
and vainfo
. The vainfo
command will return all the video codecs supported by the GPU. Hardware acceleration is also natively supported by VLC, after enabling it in the preferences, and by mplayer in this this build [6].
