Introduction
Here is how I set up an X22 to allow hot ejection/removal of the ultrabase. See also this related page for the UltraBay. These instructions are well-tested, but ymmv.
Features
- Uses lt_hotswap to preserve DMA on re-insert
- Idiot-proof (relatively)
System
- X22 thinkpad + ultrabase + DVD-R
- lt_hotswap version 0.3.9
- kernel-2.6.17.1
- xorg 6.9.0
Files
rc.local
First, make sure the lt_hotswap module is loaded. Add this to /etc/rc.local (or use modprobe.preload, if you prefer)
echo "Loading lt_hotswap module" modprobe lt_hotswap hdc_dock=1
/etc/acpi/events/lths
Disable the existing lths script. Here is the modified /etc/acpi/events/lths:
# Call the LTHS script event=lths.* #action=/usr/local/sbin/lths.sh %e action=echo "Not invoking lths.sh; this is now done by the ultrabase_eject and insert scripts instead."
/etc/acpi/events/ultrabase_eject
Respond to an ultrabase eject event. Here is /etc/acpi/events/ultrabase_eject
#Ultrabase eject button has been pressed #We can be triggered by an ibm/bay event if NOT using lt_hotswap, or an lt_hotswap event if we are. event=ibm/bay.MSTR.00000003.00000000 event=lths.MSTR.00000003.00000000 action=/etc/acpi/actions/ultrabase_eject.sh
/etc/acpi/events/ultrabase_insert
Respond to an ultrabase insert event. Here is /etc/acpi/events/ultrabase_insert
#Ultrabase has been re-inserted #We can be triggered by an ibm/bay event if NOT using lt_hotswap, or an lt_hotswap event if we are. event=ibm/bay.MSTR.00000001.00000000 event=lths.MSTR.00000001.00000000 action=/etc/acpi/actions/ultrabase_insert.sh
