我之前在笔记本电脑（Compaq CQ42 173TU）上安装了 Ubuntu Lucid，使用的是 Wubi，但声音和亮度问题仍然存在。我以为这是通过 Wubi 安装导致的问题。
所以我从 Boot 重新安装了它。但问题仍然存在。根本没有声音，但操作系统似乎没有任何问题。
而且，我无法降低亮度。亮度小程序显示“无法获取笔记本电脑面板亮度”...
以下是输出lspci-

另外，我无法检查温度。里面没有文件夹thermal_zone。
如能提供任何帮助，我将不胜感激。
答案1
我可以解决我的 compaq cq42-121la 的声音问题。
添加 ppa（通过命令行）：
sudo add-apt-repository ppa:ubuntu-audio-dev/ppa
sudo apt-get update
安装 linux-alsa-driver-modules 包（通过命令行）：
sudo apt-get install linux-alsa-driver-modules-$(uname -r)
答案2
我不太喜欢这个答案，但你可以试试 10.10 livecd。下面的链接显示你的芯片组通常受支持，但我没有看到你的笔记本电脑型号经过认证。Google 报告说许多其他人与你的情况相同。我明天看看还能找到什么，或者也许有人会抢先找到答案。
