配置声卡的时候出现耳机有声，音箱无声的问题。 alsamixer 里，如果音量下面显示的是 MM 表示此声道是静音的, 无论你如何调节这个声 道的音量都不会有声音，按 m 就可以切换到有声的模式，MM 会变为 00，再按一次 m 又 会切换到静音模式。

打包需要使用某个环境变量，如果是使用dpkg-buildpackage，只要终端中定义环境变量，然后执行dpkg-buildpackage即可。 如果是使用debuild，那么在终端中定义的环境变量是无效的，只有在执行debuild时添加-e参数，例如： % debuild -e LD_LIBRARY_PATH=/usr/gtkdfb/lib -e PKG_CONFIG_PATH=/usr/gtkdfb/lib/pkgconfg

FROM: cdebconf-0.114/debian/cdebconf-udeb.templates Packages that use debconf for configuration prioritize the questions they might ask you. Only questions with a certain priority or higher are actually shown to you; all less important questions are skipped. You can select the lowest priority of question you want to see: ‘critical’ is for items that will probably break the system without user intervention. ‘high’ is for items that don’t have reasonable defaults. ‘medium’ is for normal items that have reasonable defaults. ’low’ is for trivial items that have defaults that will work in the vast majority of cases.

FROM: http://lists.debian.org/debian-user-spanish/2003/12/msg00433.html Accepted options: invers no comment… ypan enable display panning using the VESA protected mode interface. The visible screen is just a window of the video memory, console scrolling is done by changing the start of the window. pro: * scrolling (fullscreen) is fast, because there is no need to copy around data. * You’ll get scrollback (the Shift-PgUp thing), the video memory can be used as scrollback buffer kontra: * scrolling only parts of the screen causes some ugly flicker effects (boot logo flickers for example). ywrap Same as ypan, but assumes your gfx board can wrap-around the video memory (i.e. starts reading from top if it reaches the end of video memory). Faster than ypan. redraw scroll by redrawing the affected part of the screen, this is the safe (and slow) default. vgapal Use the standard vga registers for palette changes....
