急急急 BENQ S52本本 Ubuntu不能播放音乐

moonk

我的情况是声卡被检测到是Corporation 82801FB/FBM/FR/FW/FRW/(ICH6 Family) AC97 Audio Controller 但是播放测试声音的时候测试进程就挂起了 播放MP3的时候是没有声音的
希望坛子里的兄弟帮忙了 感谢阿

这种笔记本电脑再linux下面是1024x768的分辨率， 如何设置成1280x768的分辨率？

moonk

915 resolution.c 代码如下
$sudo  gcc 915 resolution.c  -o 915 resolution 编译
产生915 resolution 执行文件
$sudo 915 resolution  -l   查看当前显示模式
$sudo 915resolution 5c 1280 768    5c为-l 显示中的一种
这样还只是修改了当前设置 重启后将会复原,所以应当在配置文件中进行设置
Ubuntu中应该修改/ect/init.d/rcS 文件
加入脚本代码  sudo 915resolution 5c 1280 768  在此之前需要拷贝文件到/sbin目录下
如果不拷贝者需要指明文件路径如/home/derek/915resolution 5c 1280 768
这样重启就会在启动GDM前设置分辨率.
