Epic: +acpi/CF problem

=Bluetooth Antenna?=

Any idea how the Bluetooth BMDC antenna looks like, how large it is, or if it is posible to install it into an X31 without Bluetooth card or Logo on the panel? [[User:Epic|Epic]]

= ACPI and CF Cards =

If you have a CF Card (mounted or unmounted) in the CF slot, it might happen, that ACPI Suspend/Hibernate modes don't work. This happened to me with an old 4 MB CF-Card, I'll try with something more recent sometime. Couldn't find anything useful about that in syslog.

= Installation Report =
Today, I installed a GNU/Linux Debian system on my X31 - without any external USB devices. This is what I did instead:

* Boot up my regular PC with Knoppix 3.8 (including Knoppix Terminal Server)
* Start terminal server. In settings, uncheck "security" to enable root access on clients!
* Link X31 to PC's network interface (either directly using a crossed cable or with normal patch cables using a switch).
* Boot up X31 (the odd boot device name stands for ethernet).
* Start knx2hd (Knoppix Menu) and install to your liking.

Note: With qtparted you even can shrink existing NTFS partitions if you dare (no guarantees), be aware that this may take some 20 minutes.

All hardware was correctly detected (sound, cisco wlan, energy savings), just hibernation lacks the suspend2 patch in kernel. Suspend to RAM works, however.

Hei,

great, thanks for the info. It would be nice if you could turn this into an Installation page with the title "Installing Knoppix on a ThinkPad X31". [[User:Wyrfel|Wyrfel]] 20:34, 28 May 2005 (CEST)

Installing Ubuntu on a ThinkPad X31

2006-08-30T08:14:04Z

Epic: acpi dapper works - update,

==Preface==
The content of this page was originally geared toward Hoary ({{Ubuntu}} 5.04),
but nearly everything here applies just as well to the Warty (4.10) and Breezy (5.10) releases.

See [http://dev.gentoo.org/~brix/papers/X31/X31.html Henrik Brix Andersens] page for a lot of useful background information.

==Installing without cdrom or floppy==
Look [[Installation on ThinkPads without CD-ROM drive|here]] or follow the [http://help.ubuntu.com/community/Installation/Netboot Netboot remarks] instructions at [http://wiki.ubuntu.com Ubuntu Wiki].

==Enabling the Access IBM Button and on-screen display for volume buttons==
Install the tpb package (use Synaptic or ''$sudo apt-get install tpb''), then use the Users and Groups Administration tool to add your user account to the 'nvram' group. Now see [[ThinkPad Button|Access IBM Button]] for configuration details.

==Choosing between APM and ACPI for power management==
I tested both, APM and ACPI but settled with ACPI which now works like a charm.

Since Ubuntu Dapper (6.06LTS) ACPI works out of the box, either in Standby Mode or Suspend to Disk Mode.
ACPI will make your system use about 10% less power than with apm, which reduces my battery runtime from ~4:00h to 3:40h.

Please read "[[How to make use of Power Management features]]" for more in depth information.

Unfortunately, if ACPI is used, hibernate and standby modes might not work with a CompactFlash card inserted. Read the [[Category_talk:X31|X31 Talk Page]] for further info.

===Disabling ACPI and using APM===
Simply disabling ACPI at boottime activates APM which works fine with suspend to ram and suspend to disk.

To disable ACPI boot your kernel with acpi=off

''...describe how to edit /boot/grub/menu.lst...''

APM based suspend to disk needs a save2disk.img hibernation file on FAT16. Use the [[tphdisk]] utility to create this file.

Use {{key|Fn}}{{Key|F4}} to suspend-to-ram and {{key|Fn}}{{key|F12}} to suspend-to-disk.

===Using ACPI===
Get ubuntulinux, radeontool and this script (which goes in /etc/acpi), nothing more!
{{NOTE|This procedure is not necessary with the Breezy Badger release, which already knows how to blank the radeon video. Just be sure you have the radeontool package installed.}}

{{cmduser|cat lid.sh}}

Talk:CF Card slot

Epic:

/dev/hde is the devicename of the CompactFlash Memory Card inserted into the Thinkpad X31's
CF Slot

The device seems to be handled by udev, but pmount which is used to mount udev devices complains, because it thinks, that: ''' Error: device /dev/hde1 is not removable''' (see the full output below.)

Unless this can be corrected (any kernel hackers around?) use /etc/fstab (will give more details on this soon --epic)

Epic: bluetooth antenna

=Bluetooth Antenna?=

Any idea how the Bluetooth BMDC antenna looks like, how large it is, or if it is posible to install it into an X31 without Bluetooth card or Logo on the panel? [[User:Epic|Epic]]

= Installation Report =
Today, I installed a GNU/Linux Debian system on my X31 - without any external USB devices. This is what I did instead:

* Boot up my regular PC with Knoppix 3.8 (including Knoppix Terminal Server)
* Start terminal server. In settings, uncheck "security" to enable root access on clients!
* Link X31 to PC's network interface (either directly using a crossed cable or with normal patch cables using a switch).
* Boot up X31 (the odd boot device name stands for ethernet).
* Start knx2hd (Knoppix Menu) and install to your liking.

Note: With qtparted you even can shrink existing NTFS partitions if you dare (no guarantees), be aware that this may take some 20 minutes.

All hardware was correctly detected (sound, cisco wlan, energy savings), just hibernation lacks the suspend2 patch in kernel. Suspend to RAM works, however.
