Current Issues

Dapper Release Candidate:

• External monitor does have correct resolution/refresh rate, probably related to bug 17761. The tty's also stop working after the external monitor has been connected.

• Wireless will not work on older BIOS versions, requires loading acerhk module and echo 1 > /proc/driver/acerhk/wirelessled, bug 30350

• Modem does not work, requires installation of sl-modem-daemon package from multiverse, bug 20397

• Infrared does not work, requires loading irda and irtty_sir modules, installation of irda-utils and irattach /dev/ttyS0. This fix appears to have stopped working and causes Deconfiguring Interfaces to stop working. Bug 34468

• Application keys do not work, requires loading acerhk module, bug 30350

Notes

[1] I've upgraded the BIOS to version 1.40.T1 (02/18/2005), which enables the software wireless switch by default. With older BIOS versions the acerhk kernel module is probably required to enable the software wireless switch, see below for instructions how to do this.

Loading acerhk kernel module and enabling wireless

The acerhk module can be loaded with the modprobe command:

 $ sudo modprobe acerhk

To ensure that the acerhk module is loaded after the next reboot add it to /etc/modules as follows:

 $ sudo -s
 # echo acerhk >> /etc/modules
 # exit

The software wireless switch can now be enabled with the following command:

 $ echo 1 > /proc/driver/acerhk/wirelessled

After configuration through System > Administration > Networking, the wireless card should now work

To enable the wireless switch on boot add the echo command to the /etc/network/if-pre-up.d/wireless-tools script which is called before the wireless card is configured. Edit the pre-configure script

 $ sudo editor /etc/network/if-pre-up.d/wireless-tools

and add the echo command as shown in the example below

 #!/bin/sh

 echo 1 > /proc/driver/acerhk/wirelessled

 IWCONFIG=/sbin/iwconfig

 if [ ! -x $IWCONFIG ]; then
  exit 0
 fi

With these changes the wireless card should be enabled automatically after a reboot.

To disable the wireless card with the software wireless switch use the following command:

 $ echo 0 > /proc/driver/acerhk/wirelessled

Enabling infrared

Load the irda and irtty_sir modules:

 $ sudo modprobe irda
 $ sudo modprobe irtty_sir

Install the irda-utils package:

 $ sudo apt-get install irda-utils

Run irattach:

 $ sudo irattach /dev/ttyS0

After a reboot an infrared phone (for example) should now show up in /proc/net/irda/discovery:

 $ cat /proc/net/irda/discovery
 IrLMP: Discovery log:

 nickname: SIEMENS S55, hint: 0xb124, saddr: 0x7ca35c24, daddr: 0x0000001d
