| = introduction = Once again I installed [http://debian.org Debian] on a notebook. This time it was a friends IBM Thinkpad X20. This is not exactly spectacular, but I ran into some small problems, which I want to write down as a reference for others. ||<tablestyle="float:right;"> '''Inhalt'''[[TableOfContents]] || = ingredients = [http://thinkwiki.org/wiki/Category:X20 Thinkwiki.org] tells you something about the ingredients of this notebook. = compatibility = The table below shows compatibility with kernel >= 2.6.15. Everything highlighted in green is fully supported. Orange means particularly supported and everything in red isn't supported at the moment. ||<rowbgcolor="#FFFFE0">component ||<rowbgcolor="#FFFFE0">comment || || '''[[Color(green:chipset)]]''' || || || '''[[Color(green:processor)]]''' || || || '''[[Color(green:video card)]]''' || || || '''[[Color(green:sound card)]]''' || || || '''[[Color(green:modem)]]''' || not tested - visit [http://thinkwiki.org/wiki/Category:X20 Thinkwiki] for more information || || '''[[Color(green:ethernet devic[[1]]]''' || || || '''[[Color(green:trackpoint)]]''' || || || '''[[Color(green:CF-Card slot)]]''' || not tested - visit [http://thinkwiki.org/wiki/CF_Card_slot Thinkwiki] for more information || || '''[[Color(green:special key[[1]]]''' || || = installation = There are [http://thinkwiki.org/wiki/Installation_on_ThinkPads_without_CD-ROM_drive several possibilities] to install Debian though it hasn't a built-in CD-ROM drive. The easiest approach is to use an external USB-drive. The installation of Debian Etch ([http://www.debian.org/devel/debian-installer/ Debian Installer Etch beta 2]) worked smoothly. = configuration = ''TODO'' = faq = Speedstep doesn't work:: After trying to load speedstep modules the following message appears: {{{FATAL: Error inserting speedstep_smi (/lib/modules/2.6.15-1-486/kernel/arch/i386/kernel/cpu/cpufreq/speedstep-smi.ko): No such device}}} To get this working you'll need a kernel with this option enabled: {{{ CONFIG_X86_SPEEDSTEP_RELAXED_CHECK = y }}} That's the case with recent Debian kernels. Go on and disable the speedstep-lib checks by by creating a /etc/modprobe.d/speedstep-lib file with this content: {{{ options speedstep-lib relaxed_check=1 }}} And then, you may add these 2 lines to /etc/modules: {{{ speedstep-lib speedstep-smi }}} ---- Speedstep still doesn't work:: You have disabled the speedstep-lib checks like explained above, but speedstep still doesn't work with kernels <=2.6.15? It's a [http://bugzilla.kernel.org/show_bug.cgi?id=5553 kernel bug]. Try to enable this kernel option: {{{ CONFIG_CPU_FREQ_DEBUG = y }}} ---- Speedstep does work but I can't use ondemand governor:: This governor doesn't work work on older laptops without Enhanced Speedstep (and guess: the X20 is a "plain-speedstep" notebook). ---- Starting with kernel 2.6.16 my soundcard doesn't work:: The alsa driver fails to probe the sound chip: {{{ PCI: Found IRQ 5 for device 0000:00:0b.0 ... never read ISV3 and ISV4 from AC'97 CS4281: probe of 0000:00:0b.0 failed with error -5 }}} It's a [http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=361197 bug]. Wait until it'll be fixed or switch back to kernel 2.6.15. = comments = ''TODO'' |
