31 <title>The Thinkpad is dead, long live the Thinkpad X230?</title>

34 <pubDate>Fri, 5 Jul 2013 08:30:00 +0200</pubDate>
35 <description>&lt;p&gt;Half a year ago, I reported that I had to find a
36 &lt;a href=&quot;http://people.skolelinux.org/pere/blog/Thank_you_Thinkpad_X41__for_your_long_and_trustworthy_service.html&quot;&gt;replacement
37 for my trusty old Thinkpad X41&lt;/a&gt;. Unfortunately I did not have much
38 time to spend on it, and it took a while to find a model I believe
39 will do the job, but two days ago the replacement finally arrived. I
40 ended up picking a
41 &lt;a href=&quot;http://www.linlap.com/lenovo_thinkpad_x230&quot;&gt;Thinkpad X230&lt;/a&gt;
42 with SSD disk (NZDAJMN). I first test installed Debian Edu Wheezy as
43 a roaming workstation, and it seemed to work flawlessly. But my
44 second installation with encrypted disk was not as successful. More
45 on that below.&lt;/p&gt;
46
47 &lt;p&gt;I had a hard time trying to track down a good laptop, as my most
48 important requirements (robust and with a good keyboard) are never
49 listed in the feature list. But I did get good help from the search
50 feature at &lt;a href=&quot;http://www.prisjakt.no/&quot;&gt;Prisjakt&lt;/a&gt;, which
51 allowed me to limit the list of interesting laptops based on my other
52 requirements. A bit surprising that SSD disk are not disks according
53 to that search interface, so I had to drop specifying the number of
54 disks from my search parameters. I also asked around among friends to
55 get their impression on keyboards and robustness.&lt;/p&gt;
56
57 &lt;p&gt;So the new laptop arrived, and it is quite a lot wider than the
58 X41. I am not quite convinced about the keyboard, as it is
59 significantly wider than my old keyboard, and I have to stretch my
60 hand a lot more to reach the edges. But the key response is fairly
61 good and the individual key shape is fairly easy to handle, so I hope
62 I will get used to it. My old X40 was starting to fail, and I really
63 needed a new laptop now. :)&lt;/p&gt;
64
65 &lt;p&gt;Turning off the touch pad was simple. All it took was a quick
66 visit to the BIOS during boot it disable it.&lt;/p&gt;
67
68 &lt;p&gt;But there is a fatal problem with the laptop. The 180 GB SSD disk
69 lock up during load. And this happen when installing Debian Wheezy
70 with encrypted disk, while the disk is being filled with random data.
71 I also tested to install Ubuntu Raring, and it happen there too if I
72 reenable the code to fill the disk with random data (it is disabled by
73 default in Ubuntu). And the bug with is already known. It was
74 reported to Debian as &lt;a href=&quot;http://bugs.debian.org/691427&quot;&gt;BTS
75 report #691427 2012-10-25&lt;/a&gt; (journal commit I/O error on brand-new
76 Thinkpad T430s ext4 on lvm on SSD). It is also reported to the Linux
77 kernel developers as
78 &lt;a href=&quot;https://bugzilla.kernel.org/show_bug.cgi?id=51861&quot;&gt;Kernel bugzilla
79 report #51861 2012-12-20&lt;/a&gt; (Intel SSD 520 stops working under load
80 (SSDSC2BW180A3L in Lenovo ThinkPad T430s)). It is also reported on the
81 Lenovo forums, both for
82 &lt;a href=&quot;http://forums.lenovo.com/t5/T400-T500-and-newer-T-series/T430s-Intel-SSD-520-180GB-issue/m-p/1070549&quot;&gt;T430
83 2012-11-10&lt;/a&gt; and for
84 &lt;a href=&quot;http://forums.lenovo.com/t5/X-Series-ThinkPad-Laptops/x230-SATA-errors-with-180GB-Intel-520-SSD-under-heavy-write-load/m-p/1068147&quot;&gt;X230
85 03-20-2013&lt;/a&gt;. The problem do not only affect installation. The
86 reports state that the disk lock up during use if many writes are done
87 on the disk, so it is much no use to work around the installation
88 problem and end up with a computer that can lock up at any moment.
89 There is even a
90 &lt;a href=&quot;https://git.efficios.com/?p=test-ssd.git&quot;&gt;small C program
91 available&lt;/a&gt; that will lock up the hard drive after running a few
92 minutes by writing to a file.&lt;/p&gt;
93
94 &lt;p&gt;I&#39;ve contacted my supplier and asked how to handle this, and after
95 contacting PCHELP Norway (request 01D1FDP) which handle support
96 requests for Lenovo, his first suggestion was to upgrade the disk
97 firmware. Unfortunately there is no newer firmware available from
98 Lenovo, as my disk already have the most recent one (version LF1i). I
99 hope to hear more from him today and hope the problem can be
100 fixed. :)&lt;/p&gt;

109 <description>&lt;p&gt;Half a year ago, I reported that I had to find a replacement for my
110 trusty old Thinkpad X41. Unfortunately I did not have much time to
111 spend on it, but today the replacement finally arrived. I ended up

113 X230&lt;/a&gt; with SSD disk (NZDAJMN). I first test installed Debian Edu
114 Wheezy as a roaming workstation, and it worked flawlessly. As I write
115 this, it is installing what I hope will be a more final installation,
116 with a encrypted hard drive to ensure any dope head stealing it end up
117 with an expencive door stop.&lt;/p&gt;
118
119 &lt;p&gt;I had a hard time trying to track down a good laptop, as my most
120 important requirements (robust and with a good keyboard) are never
121 listed in the feature list. But I did get good help from the search
122 feature at &lt;ahref=&quot;http://www.prisjakt.no/&quot;&gt;Prisjakt&lt;/a&gt;, which
123 allowed me to limit the list of interesting laptops based on my other
124 requirements. A bit surprising that SSD disk are not disks, so I had
125 to drop number of disks from my search parameters.&lt;/p&gt;
126
127 &lt;p&gt;I am not quite convinced about the keyboard, as it is significantly
128 wider than my old keyboard, and I have to stretch my hand a lot more

131 used to it. My old X40 was starting to fail, and I really needed a
132 new laptop now. :)&lt;/p&gt;
133
134 &lt;p&gt;I look forward to figuring out how to turn off the touch pad.&lt;/p&gt;

139 <title>Fourth alpha release of Debian Edu/Skolelinux based on Debian Wheezy</title>

142 <pubDate>Wed, 3 Jul 2013 14:00:00 +0200</pubDate>
143 <description>&lt;p&gt;The fourth wheezy based alpha release of Debian Edu was wrapped up
144 today. This is the release announcement:&lt;/p&gt;
145
146 &lt;p&gt;&lt;strong&gt;New features for Debian Edu 7.1+edu0~alpha3 released
147 2013-07-03&lt;/strong&gt;&lt;/p&gt;
148
149 &lt;p&gt;These are the release notes for for Debian Edu / Skolelinux
150 7.1+edu0~alpha3, based on Debian with codename &quot;Wheezy&quot;.&lt;/p&gt;
151
152 &lt;p&gt;&lt;strong&gt;About Debian Edu and Skolelinux&lt;/strong&gt;&lt;/p&gt;
153
154 &lt;p&gt;&lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Debian Edu, also known as
155 Skolelinux&lt;/a&gt;, is a Linux distribution based on Debian providing an
156 out-of-the box environment of a completely configured school
157 network. Immediately after installation a school server running all
158 services needed for a school network is set up just waiting for users
159 and machines being added via GOsa², a comfortable Web-UI. A netbooting
160 environment is prepared using PXE, so after initial installation of
161 the main server from CD, DVD or USB stick all other machines can be
162 installed via the network. The provided school server provides LDAP
163 database and Kerberos authentication service, centralized home
164 directories, DHCP server, web proxy and many other services. The
165 desktop contains
166 &lt;a href=&quot;http://people.skolelinux.org/pere/blog/Educational_applications_included_in_Debian_Edu___Skolelinux__the_screenshot_collection____.html&quot;&gt;more
167 than 60 educational software packages&lt;/a&gt; and more are available from
168 the Debian archive, and schools can choose between KDE, Gnome, LXDE
169 and Xfce desktop environment.&lt;/p&gt;
170
171 &lt;p&gt;This is the fourth test release based on Debian Wheezy. Basically
172 this is an updated and slightly improved version compared to the
173 Squeeze release.&lt;/p&gt;
174
175 &lt;p&gt;&lt;strong&gt;Software updates&lt;/strong&gt;&lt;/p&gt;
176 &lt;ul&gt;
177 &lt;li&gt;Dropped ispell dictionaries from our default installation.&lt;/li&gt;
178 &lt;li&gt;Dropped menu-xdg from the KDE desktop option, to drop the Debian
179 submenu. It was not included with Gnome, LXDE or Xfce, so this
180 brings KDE in line with the others.&lt;/li&gt;
181 &lt;li&gt;Dropped xdrawchem, xjig and xsok from our default installation as
182 they don&#39;t have a desktop menu entry and thus won&#39;t show up in the
183 menu now that menu-xdg was removed.&lt;/li&gt;
184 &lt;li&gt;Removed the killer system to kill left behind processes on
185 multi-user machines, as it was no longer able to understand when a
186 X display was in use and killed the processes of the active users
187 too.&lt;/li&gt;
188 &lt;li&gt;Dropped the golearn (from goplay) package as the debtags in wheezy
189 are too few to make the package useful.&lt;/li&gt;
190 &lt;/ul&gt;
191 &lt;p&gt;&lt;strong&gt;Other changes&lt;/strong&gt;&lt;/p&gt;
192 &lt;ul&gt;
193 &lt;li&gt;Updated artwork matching http://wiki.debian.org/DebianArt/Themes/Joy
194 &lt;li&gt;Multi-arch i386/amd64 USB stick ISO available.&lt;/li&gt;
195 &lt;li&gt;Got rid of ispell/wordlist related debconf questions that showed
196 up for some language options.&lt;/li&gt;
197 &lt;li&gt;Switched to using http.debian.net as APT source by default.&lt;/li&gt;
198 &lt;li&gt;Fixed proxy configuration on Main Server installations.&lt;/li&gt;
199 &lt;li&gt;Changed LTSP setup to ask dpkg to use force-unsafe-io the same way
200 d-i is doing it.&lt;/li&gt;
201 &lt;li&gt;Made sure root and user passwords were not left behind in the
202 debconf database after installation on Main Server installations.&lt;/li&gt;
203 &lt;li&gt;Made Roaming Workstation dynamic setup more robust and added draft
204 script setup-ad-client to hook a Roaming Workstation up to a
205 Active Directory server instead of a Debian Edu Main Server.&lt;/li&gt;
206 &lt;li&gt;Update system to install needed firmware packages during
207 installation, to work properly in Wheezy.&lt;/li&gt;
208 &lt;li&gt;Update system to handle hardware quirks (debian-edu-hwsetup).&lt;/li&gt;
209 &lt;li&gt;Corrected PXE installation setup to properly pass selected desktop
210 and keymap settings to PXE installation clients.&lt;/li&gt;
211 &lt;li&gt;LTSP diskless workstations use sshfs by default, allowing them to
212 work without adding them to DNS and NIS netgroups for NFS access.&lt;/li&gt;
213 &lt;/ul&gt;
214 &lt;p&gt;&lt;strong&gt;Known issues&lt;/strong&gt;&lt;/p&gt;
215 &lt;ul&gt;
216 &lt;li&gt;No mass import of user account data in GOsa (ldif or csv)
217 available yet (698840).&lt;/li&gt;
218 &lt;li&gt;Artwork not enabled for all desktops.&lt;/li&gt;
219 &lt;/ul&gt;
