我的机器是IBM T43。将内核由2.6.21-r4升级到2.6.24-r3,出现了问题,怎么也解决不了。
1. alsa的问题
按照
http://www.gentoo.org/doc/en/alsa-guide.xml
http://www.gentoo-cn.org/doc/zh_cn/alsa-guide.xml
重新设置了很多遍,还是发不出声音,按照论坛里一些哥们的方法,调用alsa-mixer将
headphone和line设为mute,也是发生不了。下面是一些信息:
- ~$cat /proc/asound/cards
- 0 [ICH6 ]: ICH4 - Intel ICH6
- Intel ICH6 with AD1981B at irq 18
- 1 [Modem ]: ICH-MODEM - Intel ICH6 Modem
- Intel ICH6 Modem at irq 19
- ~$cat /proc/asound/version
- Advanced Linux Sound Architecture Driver Version 1.0.15 (Tue Nov 20 19:16:42 2007 UTC).
- ~$cat /proc/asound/oss/sndstat
- Sound Driver:3.8.1a-980706 (ALSA v1.0.15 emulation code)
- Kernel: Linux Qiang 2.6.24-gentoo-r3 #3 Tue Mar 25 16:50:54 CST 2008 i686
- Config options: 0
- Installed drivers:
- Type 10: ALSA emulation
- Card config:
- Intel ICH6 with AD1981B at irq 18
- Intel ICH6 Modem at irq 19
- Audio devices:
- 0: Intel ICH6 (DUPLEX)
- 1: Intel ICH6 Modem - Modem (DUPLEX)
- Synth devices: NOT ENABLED IN CONFIG
- Midi devices: NOT ENABLED IN CONFIG
- Timers:
- 7: system timer
- Mixers:
- 0: Analog Devices AD1981B
- 1: Conexant id 23
复制代码
下面是alsamixer的示意图。
我现在怀疑是不是机器调节音量的按钮不起作用了
2. 蓝牙的问题
以前能够调用Fn+F5开关蓝牙设备,现在却不行了。如果在windows下面打开了蓝牙,到linux就关不了;如果在windows下面关了蓝牙,到linux下就打开不了。
按照
添加
042. # nano -w /etc/acpi/events/ibm-bluetooth
# FN+F5 (bluetooth)
event=ibm/hotkey HKEY 00000080 00001005
action=/etc/acpi/actions/toggle_bluetooth.sh
043. # nano -w /etc/acpi/actions/toggle_bluetooth.sh
#!/bin/bash
# toggle bluetooth
grep status /proc/acpi/ibm/bluetooth|grep -q enabled
if [ $? == 0 ]; then
echo disabled > /proc/acpi/ibm/bluetooth
/etc/init.d/bluetooth stop --quiet
else
echo enabled > /proc/acpi/ibm/bluetooth
modprobe rfcomm
/etc/init.d/bluetooth restart --quiet
fi
044. # chmod a+x /etc/acpi/actions/toggle_bluetooth.sh
也是没有任何效果。 |
