openSUSE 11.4

Posted by – 18. März 2011


After 8 months of work openSUSE 11.4 has been released last week!
This has been celebrated with release parties all around the world.
As usual, the new release comes with the latest kernel,
LibreOffice, Gnome and KDE packages.

In Nuremberg, we celebrated the release with a party at the Artefakt bar, and had the fabulous Ukulele Insanity playing live.

 

Althogh the release is considered a very good one by many press and user reviews, I had some small problems after upgrading to it and want to share with you how I solved those:

Networkmanager:

After suspending and waking up my notebook, the kde networkmanager always deactivated the network. From /var/log/NetworkManager:

NetworkManager[2960]: (wlan0): deactivating device (reason: 2).
NetworkManager[2960]: (wlan0): supplicant interface state: starting -> ready
NetworkManager[2960]: (wlan0): device state change: 2 -> 3 (reason 42)<>

I found out, that for KDE 4.5 or later it is recommended to switch from using KNetworkManager to using the Networkmanagement Plasmoid instead. This is done by:

zypper in plasmoid-networkmanagement and allowing the removal of NetworkManager-kde4

Crypto partitions:

I am using a crypted home partition since a long time, and this was configured in /etc/cryptotab and enabled during boot in /etc/init.d/boot.crypto until the upgrade.

With the recent release this changed to /etc/crypttab and gets enabled in /etc/init.d/boot.crypto-early. To convert it, I changed my old cryptotab entry:

/dev/loop  /dev/sda6  /home/tom  ext4  twofish256 noatime,acl,user_xattr

to

cr_sda6  /dev/sda6  none  cipher=twofish-cbc-plain,size=256,hash=sha512

in /etc/crypttab and added to /etc/fstab:

/dev/mapper/cr_sda6  /home/tom  ext4  noatime,acl,user_xattr

Beeping X:

I think it’s highly annoying that X makes a load beep sound when killing it by ctrl+alt+delete. To turn this off, just add a file named /etc/X11/xorg.conf.d/50-disable-beep.conf with this content:

Section "ServerFlags"
Option "ZapWarning" "off"
EndSection

Iscan – udev rules change

The package iscan (Image Scan) from epson uses a deprecated syntax for it’s udev rules so that the
startup log gets spammed with lots of warnings. To fix it just run:

sudo sed -i -e “s:SYSFS:ATTRS:g” /etc/udev/rules.d/60_iscan.rules

Screen resolution:

Somehow it seems the screen of my T60p gets detected incorrectly:

xdpyinfo | grep resolution returns a resolution of 96×96 dots per inch, but for my taste everything gets rendered too small. So I helped myself by running:

xrandr --dpi 120
systemsettings - application appearance - fonts - force 120 dpi

on startup. Although I’m quite sure this is not the elegant way of solving this ;-)
