Ubuntu关机&耳机插拔声音异常解决方案
由于英语一直很差,所以每次安装ubuntu最纠结的事情就是,开关机以及插拔耳机时候异常声音,16年突然找到完美解决方案了,却总是忘记保存下来
在/etc/modprobe.d/创建一个modprobe.conf 的文件
options snd-hda-intel model=,generic
把alsa的auto mute 给关掉
sudo alsamixer
按F6选择第二个显卡（HDA INTEL PCH），然后把auto mute 改为disabled
sudo alsactl store
ubuntu 引导win花屏，改分辨率
In my case screen resolution is 1440X900. Somebody says that changing grub window resolution to actual resolution of monitor makes boot faster(but I don’t see this take effect in last versions o Ubuntu). So I’ve changed and uncommented one line in /etc/default/grub to this: GRUB_GFXMODE=1440x900 Then to change purple background of grub I created the image,in my case just black image with 1440X900 resolution and put it in /boot/grub. So my file is: /boot/grub/gbackground.jpg Then I’ve edited again /etc/default/grub and puted a line in it: GRUB_BACKGROUND=/boot/grub/gbackground.jpg then I updated grub configuration with command: sudo update-grub
