CyberFox's questions

我正在尝试让我的 HP Laser-Jet 1020 与我的 Ubuntu 18.04 安装一起使用。我已经hplip从 HP 的官方网站成功安装，但它似乎不起作用，因为 Ubuntu 似乎更喜欢 foomatic 驱动程序，并且会拒绝在任何其他驱动程序上打印。我试图从打印机属性中将品牌和型号更改为 hplip 3.19.1，但它不再起作用。我确保我拥有所有依赖项。我也做过hp-setup -i，交互式和经过处理的 GUI，具有相似的结果。插件已成功安装，设置和固件相同，但打印机最多只能打印单面文档。打印机属性中没有可安装的选项，也没有要检查的双面打印器安装复选框。（除非我尝试将 hplip 3.19 与专有插件一起使用，但它甚至不打印）在所有其他应用程序中，双双面打印选项被禁用（灰显）。有什么建议么 ？

PS我做到了：sudo apt-get purge hplipand sudo apt-get autoremoveand sudo apt-get autoclean，这样我就可以开始干净了。

另一个有趣的事情是，虽然我安装了 hplip 3.19，dpkg -l hplip但仍然显示安装了 3.17 版本。

谢谢！

我正在使用带有 4.15.0.29 通用内核的 Ubuntu 18.04。启动过程需要很长时间，我注意到启动时字体样式发生了变化。我已经在谷歌上尝试了很多东西，但它们什么也没做，所以我恢复到安装后快照（这个），因为没有其他解决了我的问题。（我正在使用时移）

PS 我尝试自己进行一些调试和研究，但 3 小时后我一无所获。

PSS 这在内核 4.18 上仍然存在。（为此而尝试）
