Installation instructions for the ThinkPad X24
Specific installation notes for the ThinkPad X24.

General Notes
If you don't have a CD-ROM solution, please look at Installation on ThinkPads without CD-ROM drive.
Distro specific Instructions
Debian 4.0 Etch
Miscellaneous
Use a default depth of 16 in xorg.conf alongwith the radeon driver. The radeonfb patch will fix the problem with high power drain in ACPI sleep
Ubuntu 7.04 - Feisty Fawn
Video Adapter
By default Ubuntu sets the ati driver in xorg.conf. It is a wrapper which points (on the X24) to the radeon driver. You could simply displace ati by radeon. If you want use desktop effects you have to lower the depth to 16. On depth 24 the video adapter does not provide direct rendering, which is necessary for an acceptable animation performance.
Wireless LAN Mini-PCI Adapter
There are 3 drivers shipped with the standard kernel of Ubuntu: orinoco_pci (WEP), prism2_pci (WEP) and hostap_pci (WEP/WPA/WPA2). All 3 are active by default. Usually the orinoco driver should be used in a standard installation. With a blacklist you could activate/deactivate a special driver. You can provide a blacklist by creating a file in /etc/modprobe.d.
orinoco
The recommended driver is the orinoco_pci. If you want use the orinoco driver you have to create a file in /etc/modprobe.d where you blacklist the other 2 drivers:
/etc/modprobe.d/blacklist-wlan
blacklist hostap blacklist hostap_pci blacklist prism2_pci
hostap
If you want use WPA or WPA2 encryption with your wireless lan adapter you have to use the hostap driver. But be aware. (In combination with the network manager) You could have trouble with mounting/unmounting filesystems. The blacklist in /etc/modprobe.d should look like this:
/etc/modprobe.d/blacklist-wlan
blacklist hermes blacklist orinoco blacklist orinoco_pci blacklist prism2_pci
If you have trouble to connect to an access point you should check the firmware version of your wireless adapter:
> dmesg | grep wifi ... wifi0: NIC: id=0x8013 v1.0.0 wifi0: PRI: id=0x15 v1.1.0 wifi0: STA: id=0x1f v1.4.9
With some older versions the hostap driver have some stability issues. I use the combination of 1.1.1 and 1.7.4 which seems to be the most reasonable firmware versions:
wifi0: NIC: id=0x8013 v1.0.0 wifi0: PRI: id=0x15 v1.1.1 wifi0: STA: id=0x1f v1.7.4
How to upgrade your firmware is explained on http://linux.junsun.net/intersil-prism/. Some firmware versions are hosted on http://www.netgate.com/support/prism_firmware.
You will find a detail description of the 3 linux wlan drivers on: http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/Linux.Wireless.drivers.802.11b.html
Standby or Suspend-to-Ram
If you have trouble with you standby mode and you use the Network Manager, you should deactivate the Network Manager before entering the standby mode by adding the following file to /etc/acpi/suspend.d:
/etc/acpi/suspend.d/05-network-manager.sh
#!/bin/sh
dbus-send --system \
--dest=org.freedesktop.NetworkManager \
/org/freedesktop/NetworkManager \
org.freedesktop.NetworkManager.sleep
and resume:
/etc/acpi/resume.d/91-network-manager.sh
#!/bin/sh
dbus-send --system \
--dest=org.freedesktop.NetworkManager \
/org/freedesktop/NetworkManager \
org.freedesktop.NetworkManager.wake
This seems to solve the problem. (Found on: https://bugs.launchpad.net/ubuntu/feisty/+source/network-manager/+bug/40125)
