我下载了nvidia-kernel-source，然后尝试安装他的编译依赖
sudo aptitude build-dep nvidia-kernel-source -f，然后好像并没有正常解决变异依赖。
~/D/n/nvidia-graphics-drivers-440.100 $ dpkg-buildpackage -B -j10 dpkg-buildpackage: info: source package nvidia-graphics-drivers dpkg-buildpackage: info: source version 440.100-1~bpo10+1 dpkg-buildpackage: info: source distribution buster-backports dpkg-buildpackage: info: source changed by Luca Boccassi <bluca@debian.org> dpkg-buildpackage: info: host architecture amd64 dpkg-source --before-build . dpkg-checkbuilddeps: error: Unmet build dependencies: debhelper-compat (= 13) dpkg-buildpackage: warning: build dependencies/conflicts unsatisfied; aborting dpkg-buildpackage: warning: (Use -d flag to override.)
所以，debhelper-compat到底是个啥
我就是想安装显卡驱动。。。
好了，现在的问题是显卡好像不能够正常工作
