<p>MK-Stuff: /* Power Management */</p> <hr /> <div>This page aims to illustrate issues and (hopefully) solutions encountered while installing {{Ubuntu}} 5.10 (Breezy Badger) on a Levono ThinkPad {{R50e}}. As usual, caveat emptor. Also, don't forget to create backup CDs for your IBM Rescue and Recovery partition (see [[Ordering Recovery CDs]]).<br /> <br /> The configuration of the ThinkPad used is as following:<br /> Levono ThinkPad R50e 1834-A67 (a Taiwan-specific model?)<br /> [[Intel Celeron M]] 360 (Dothan 1.4GHz)<br /> [[Intel 855GM]] Chipset<br /> 14' XGA (1024x768) TFT<br /> [[Intel PRO/Wireless 2200BG Mini-PCI Adapter]]<br /> DVD±RW Writer (Not removable)<br /> Windows XP Home<br /> <br /> <br /> == Installation ==<br /> <br /> Installing the OS was fairly straight forward. I put in the Ubuntu install disc and pressed F12 to bring up the booting device menu. At the partitioning menu I chose to let Ubuntu resize the existing NTFS partition and create partitions it needed automatically. Everything went well and I was able to boot into both Windows XP Home and the [[Rescue and Recovery]] partition from [[GRUB]] without any extra effort. It should be noted, however, that I did this on a brand new machine. So if you had made changes to your MBR or partitioning table, you might get different results.<br /> <br /> <br /> == Networking ==<br /> <br /> The Ethernet interface works right after installation as expected (eth1). The [[Intel PRO/Wireless 2200BG Mini-PCI Adapter]] was detected (eth0), but probably only works with open networks (I didn't have one to test). As my wireless network (Apple Airport Express) uses WPA/WPA2, I went straight on to make ipw2200 work with wpa_supplicant. This turned out to be quite a complicated task since most articles on enabling WPA on ipw2200 in Ubuntu are written for earlier versions of Ubuntu.<br /> <br /> There are plenty of instructions on the 'net for configuring ipw2200 with wpa_supplicant. Unfortunately most of them are geared toward other distro or Ubuntu 5.04 Hoary, which make the situation confusing, to say the least. While there is [http://ubuntuforums.org/showthread.php?t=90450 an instruction] specifically written for Breezy Badger, I had installed and removed different versions of drivers/firmwares so many times that I actually cannot remember exactly what made it work. Therefore, I'll provide links to website which I visited and some rough instructions on how I did it.<br /> <br /> The driver/firmware combination that works for me is as following:<br /> <br /> [http://ipw2200.sourceforge.net/#downloads ipw2200 1.0.8] (1.1.2 verified to work)<br /> [http://ipw2200.sourceforge.net/firmware.php Intel® PRO/Wireless 2200BG Driver Firmware 2.4] (3.0 verified to work)<br /> [http://ieee80211.sourceforge.net/ ieee80211 subsystem 1.1.6] (1.1.13 verified to work)<br /> <br /> First, in order to compile the drivers, follow the instructions [http://www.ubuntuforums.org/showthread.php?t=26623 here] to install the necessary packages. While you're there, follow the instructions to add extra repositories. Then go [http://doc.gwos.org/index.php/Install_ipw2200 here] for instructions of installing the drivers/firmware. Then finally, go [http://ubuntuforums.org/showthread.php?t=90450 here] and follow the instructions from <br /> '''4. Edit wpasupplicant configuration files''' and on; except at <br /> '''5. Configure wpasupplicant to start when booting''', instead of '''sudo ln -s ../init.d/wpasupplicant S40iwpa''', do '''sudo update-rc.d wpasupplicant defaults'''.<br /> <br /> If you have been messing around installing different versions of drivers, then you definitely want to have a look at [http://72.14.207.104/search?q=cache:G2Dan1PweWAJ:www.goldfisch.at/knowledge/337++ipw2200:+disagrees+about+version+of+symbol+ieee80211_get_crypto_ops&amp;hl=en&amp;gl=nz&amp;ct=clnk&amp;cd=1&amp;client=firefox-a this]. <br /> <br /> There's a really long wait during booting (if you don't have an Ethernet cable plugged in) when init.d is waiting for the network interface to load. I suspect it might have something to do with /etc/init.d/wpasupplicant, which starts the wpa_supplicant deamon and waits for the name interface to come up. I haven't go around to playing with this though, so if you find some way to modify the file to change this behavior, please contribute.<br /> <br /> One thing that's still unsolved (beside the long wait during booting) is this error message from dmesg:<br /> <br /> ipw2200: Can't set TKIP countermeasures: crypt not set!<br /> <br /> I tried disabling hardware crypto following the instructions [http://www.ubuntuforums.org/showpost.php?p=459401&amp;postcount=461 here], but it didn't seem to do any good. Please contribute if you have a solution for this.<br /> <br /> Here's a list of links I consulted:<br /> <br /> [https://wiki.ubuntu.com/WPAHowto ubuntu Wiki's WPA How-To]<br /> [http://www.ubuntuforums.org/showthread.php?t=26623 HOWTO: ipw2200 + wpa]<br /> [http://doc.gwos.org/index.php/Install_ipw2200 HOWTO: Compile/Install latest version of ipw2200]<br /> <br /> I do not use the built-in modem, so I didn't bother testing it. However, it was suggested [http://www.kaltertee.de/R50e.html here] that [http://www.linuxant.com/drivers/hsf/full/downloads-ubuntu-x86.php Conexant's driver] works.<br /> <br /> == Power Management ==<br /> <br /> Some webpages have instructions on how to enable SpeedStep support for Celeron M. But according to [http://www.intel.com/products/processor_number/proc_info_table.pdf Intel], none of the Celeron M processor (at least the new ones) support it. I tried loading p4_clockmod and cpufreq_userspace, and only the latter worked. I suppose it might be useful if you want to manually adjust the speed of your CPU. Or, if your CPU supports SpeedStep (e.g. Pentium M), see [http://www.plenz.com/thinkpad_R50e#cpufreq here] for instructions on how to make it work.<br /> <br /> The fan seems to work fine without any tweaking as indicated [http://www.mk-stuff.de/artikel/linux_on_an_ibm_thinkpad_r50e/#acpi-fan here].<br /> <br /> == Standby, Sleep and Hibernation ==<br /> <br /> '''Standby''' Hitting Fn+F3 blanks the screen and turns the backlight off. It is supposed to lock the screen, but sometimes it doesn't work; I haven't been able to figure out what causes this. No additional changes are necessary.<br /> <br /> '''Sleep''' To make sleeping work, the following changes are needed:<br /> <br /> Open a terminal and enter this command:<br /> <br /> sudo gedit /etc/default/acpi-support<br /> <br /> And uncomment &quot;ACPI_SLEEP=true&quot; (by removing the # character in front of it)<br /> <br /> Then enter this command in terminal:<br /> <br /> sudo cp /etc/acpi/sleep.sh /etc/acpi/sleep.sh_backup<br /> sudo gedit /etc/acpi/sleep.sh<br /> <br /> Replace the line &quot;echo -n $ACPI_SLEEP_MODE &gt;/sys/power/state&quot; with <br /> (take from [[Problem with display remaining black after resume]]):<br /> <br /> # change to console 1<br /> FGCONSOLE=`fgconsole`<br /> chvt 6<br /> <br /> # safe video state<br /> cat /proc/bus/pci/00/02.0 &gt; /tmp/video_state<br /> <br /> # sync filesystem<br /> sync<br /> <br /> # sync hardware clock with system time<br /> hwclock --systohc<br /> <br /> # go to sleep<br /> echo -n 3 &gt; /proc/acpi/sleep<br /> <br /> # waking up<br /> # restore system clock<br /> hwclock --hctosys<br /> <br /> # restore video state<br /> cat /tmp/video_state &gt; /proc/bus/pci/00/02.0<br /> <br /> # change back to X<br /> chvt $FGCONSOLE<br /> <br /> # clean up behind us<br /> rm /tmp/video_state<br /> <br /> <br /> Press Fn to wake up. Screen locking works consistently, unlike standby.<br /> <br /> '''Hibernation''' Hibernation works straight out of the box. Press Fn+F12 or choose Hibernation from the logout menu to hibernate.<br /> <br /> <br /> == Display and external monitor ==<br /> <br /> The built-in [[Intel Extreme Graphics 2]] works just fine with the built-in display. You can use [http://sourceforge.net/projects/i855crt i855crt] (proceed with caution) to make the TFT and external monitor/projector mirror each other, but I found that much less useful than screen spanning. I'm still working on this. Please contribute if you have a solution.<br /> <br /> <br /> == Various Tweaks ==<br /> <br /> Refer to [[Installing Ubuntu 5.04 on a ThinkPad T43 (1875)]] for the following tweaks:<br /> * Don't slow down boot-up by synchronizing with network time<br /> * Don't slow down boot-up when no Ethernet cable is attached<br /> <br /> Refer to [http://columbia.edu/~em36/ubuntubreezythinkpadt42.html Ubuntu Linux 5.10 Breezy Badger on an IBM ThinkPad T42] for the following tweaks:<br /> * Enable TrackPoint middle-button scrolling<br /> * Enable Page-Back and Page-Forward keys in Firefox (doesn't yet work with FireFox 1.5)<br /> Note: I suggest configuring them as PgUp and PgDn instead. Just put this in ~/.Xmodmap:<br /> keycode 234 = Prior<br /> keycode 233 = Next<br /> Log out and log again.<br /> <br /> * Install on-screen confirmation for the ThinkPad buttons (other than Fn+F5)<br /> * Visual feedback for Fn+F5 (I'd recommend against it because the script crashed my system.)<br /> <br /> == Special Notes on speeding up booting by not initiating network interface(s) and/or ifplugd ==<br /> If you have ipw2200 configured with wpa_supplicant, you should leave HOTPLUG_INTERFACES=&quot;&quot; in /etc/default/ifplugd as it is. Otherwise it produces an annoying error message during booting. Also, ipw2200+wpa_supplicant takes a long time to initiate, so there's still a wait during booting, <br /> and I haven't found a way around it yet (besides plugging in an Ethernet cable). There is a fix suggested in [http://columbia.edu/~em36/ubuntubreezythinkpadt42.html#netmanager here], but it doesn't seem to work when you have ipw2200 working with wpa_supplicant (it actually disables the wireless connection). If you have any suggestions, please let me know.<br /> <br /> == References ==<br /> [http://www.kaltertee.de/index.php?current=linux Installing Ubuntu Breezy Badger (5.10) on ThinkPad R50e (German)]<br /> <br /> [http://columbia.edu/~em36/ubuntubreezythinkpadt42.html Ubuntu Linux 5.10 Breezy Badger on an IBM ThinkPad T42]</div>
