Skype on Ubuntu 11.10 (Oneiric Ocelot)

If you upgrade to Ubuntu 11.10 on a 64-bit platform and try to run skype then you will likely get this error:

skype: error while loading shared libraries: libXss.so.1: cannot open shared object file: No such file or directory

This is because libxss1 and a few other libraries have been removed from ia32-libs package.

You will need to enable multiarch and install the extra 32 bit libraries by hand:

Kabouter: a gnome terminal based multi-ssh connector

Kabouter is Dutch for gnome and also a tool to connect to a range of IP addresses via ssh. It uses gnome-terminal to manage the sessions which, for me, seems more natural than some of the other 3rd party SSH applications available.

Usage is simple:

[email protected]:~$ kabouter ampli 172.19.18.65 172.19.18.96

This creates a gnome-terminal session with 32 tabs connecting to the range of SSH enabled machines. This works very well when using it with SSH Multiplexing which then gives you a way to automate remote commands through SSH without needing secure key authentication and without having to authenticate each time you want to run a command.

Wireless BCM4312 3.0 kernel

Broadcom Chipset BCM4312

With the latest 3.0 kernel there is still no “out of the box” support for my BCM4312 wireless chipset. Nor is there any help from Ubuntu 11.04 leaving me to use Broadcoms hybrid driver with patch.

Chipsets supported by “Broadcom’s IEEE 802.11a/b/g/n hybrid Linux┬« device driver” are: BCM4311, BCM4312, BCM4313, BCM4321, BCM4322, BCM43224, and BCM43225, BCM43227 and BCM43228.

My specific chipset from lspci command:

Broadcom Corporation BCM4312 802.11b/g LP-PHY (rev 01)

Ubuntu 11.04 Natty with fglrx and 2.6.39

Natty (11.04) users can finally get fglrx playing nicely together with X.org 1.10. We can also make the latest driver work well with the 2.6.39 kernel.

Custom build procedure:

  1. Install the latest 2.6.39 kernel revision from Ubuntu Mainline or install the PPA.
  2. Download 64-bit 11.4.
  3. Extract the files from the package:
    sh ./ati-driver-installer-11-4-x86.x86_64.run --extract ati
  4. For 2.6.39 support, download this extra patch: 2.6.39_bkl.patch
  5. Check for Big Kernel Lock usage:
    cat /lib/modules/`uname -r`/build/.config | grep -c CONFIG_BKL=y
    If the result of this command is 0, then download no_bkl.patch as well.
  6. then apply them:
    cd ati; for i in ../*.patch; do patch -p1 < $i; done
  7. Build your new ati/fglrx deb packages:
    ./ati-installer.sh 8.841 --buildpkg Ubuntu/natty
  8. Install our newly created deb packages:
    sudo dpkg -i ../fglrx*.deb
  9. If your /etc/X11/xorg.conf is missing you will need to run:
    sudo aticonfig --initial
    and then reboot.

That newly created package should work for the entire 2.6.39 series.

Ubuntu 2.6.39 kernel and fglrx 8.831

For those 10.10 Maverick users with 2.6.38 or 2.6.39 (64-bit) kernels, you can get fglrx playing nicely together with X.org 1.9.

Unfortunately this new driver does not support X.org 1.10 and that leaves 11.4 users to use the open-source drivers.

Custom build procedure:
