Pango-warning

当我用sudo命令开启emacs后，会异常卡顿，而且过一会就崩溃。但是我之用emacs命令打开就没问题。前几天还能好好用的。错误信息： (emacs:25070): Pango-WARNING **: 21:45:17.502: failed to create cairo scaled font, expect ugly output. the offending font is ‘IPAexGothic 11’ (emacs:25070): Pango-WARNING **: 21:45:17.464: font_face status is: (emacs:25070): GdkPixbuf-WARNING **: 21:45:17.499: Error loading XPM image loader: Unable to load image-loading module: /usr/lib/x86_64-linux-gnu/gdk-pixbuf-2.0/2.10.0/loaders/libpixbufloader-xpm.so: /usr/lib/x86_64-linux-gnu/gdk-pixbuf-2.0/2.10.0/loaders/libpixbufloader-xpm.so: cannot open shared object file: Too many open files (emacs:25070): Pango-WARNING **: 21:45:17.502: scaled_font status is: out of memory

错误似乎是由什么字体引起的？可是为什么不用sudo就没问题呢？

而且emacs会变成这样。

原因出在这里，你的 root 用户开了太多文件超过系统限制数量了。

用 lsof -u root 看那些程序开了文件。

后面还有一堆这样的错误，可是这些东西并不是我自己开的

LdBeth · 2019 年5 月 1 日 03:13

sudo rm -rf /

请。

et2010 · 2019 年5 月 1 日 03:13

这种打开方式不对啊，用 sudo-edit 吧，不要用sudo打开整个emacs

super-buster · 2019 年5 月 1 日 03:39

不过我以前一直就是这么干的, 我用sudoedit打开文件总是报错

super-buster · 2019 年5 月 1 日 03:40

重装系统而已。。

cireu · 2019 年5 月 1 日 05:07

用tramp启用sudo

M-x find-file RET sudo::/path/to/file RET
