[已解决]citx 在 KDE 中启动慢

我根据ArchWIki安装了‘plasma’ 包组，安装完成后启动KDE很慢（我是通过 xorg-xinit 启动图形界面的），要等2~3分钟才启动完成，桌面显示后1分钟内只能移动鼠标，无法点击，无法按键盘。我在`/etc/xdg/autostart`中排除后才发现是fcitx的问题。
将fcitx的启动脚本从`/etc/xdg/autostart`中移除后启动时间才没那么慢，但是当我进入KDE，在启动器中启动fcitx后还是要卡1分钟这样。
在我的dwm中则不会遇到启动fcitx慢，会卡的现象。
这是fcitx的启动时控制台的输出：

** (process:18261): WARNING **: 20:43:29.718: Error loading plugin: libaspell.s

(ERROR-18261 ime.c:432) fcitx-keyboard-tr-otk already exists

以上的WARNING和ERROR在dwm中启动fcitx时也会出现，似乎不是由这些造成的

strace 会用不？

Re: [已解决]citx 在 KDE 中启动慢

我对strace不是很了解，但我尝试

 strace -tt -T fcitx

并得到输出

Re: [已解决]citx 在 KDE 中启动慢

fcitx fork 走了，你需要加 -f。

另外你不试试 fcitx5 么？

Re: [已解决]citx 在 KDE 中启动慢

你说的7号指的是

33039 14:23:30.541437 recvmsg(7, {msg_name=NULL, msg_namelen=0, msg_iov=[{iov_base="\34\0o\f\306\1\0\0'\0\0\0K\267*\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0", iov_len=4096}], msg_iovlen=1, msg_controllen=0, msg_flags=0}, 0) = 32 <0.000163>

中函数第一个参数是7的吗？
不是

33039 14:23:30.541147 <... epoll_wait resumed>[{events=EPOLLIN, data={u32=3892318288, u64=140122905382992}}], 6, -1) = 1 <14.731075>

这一行等了近15秒吗（我对linux系统调用不是很了解）

我向上找了几条第一个参数是7的：

33037 14:23:15.807955 poll([{fd=7, events=POLLIN|POLLOUT}], 1, -1 <unfinished ...>
33037 14:23:15.808039 writev(7, [{iov_base="\31\0\v\0\36\0\0\3\0\0\0\0!\10\0\0\36\0\0\3\267\2\0\09\0\4\0\1\0\1\0"..., iov_len=48}], 1 <unfinished ...>
33037 14:23:15.808097 poll([{fd=7, events=POLLIN}], 1, -1 <unfinished ...>
33037 14:23:15.808246 recvmsg(7,  <unfinished ...>

Re: [已解决]citx 在 KDE 中启动慢

你应该找创建了这个 7 号文件描述符的调用（大概率是 xxx(...) = 7 这样，也有例外）。
对它不了解就去了解？推荐阅读 APUE。

是不是这样的：

我从等了近15秒那一行往上找` = 7 `，第一个找到的就是这行

显然不是……你真的对系统调用了解很少……
要不你把整个日志找个地方发出来吧。比如往 fars.ee 里塞。

Re: [已解决]citx 在 KDE 中启动慢

好奇怪，这个是到 X 的连接。为什么会卡在这里这么久呢……

在KDE中启动fcitx5后，我在Xorg的日志中找到一行：

[  1409.611] (EE) event7  - Synaptics TM3383-002: client bug: event processing lagging behind by 11ms, your system is too slow

在dwm中启动fcitx5则没有这条错误

是啊，Xorg 有点卡卡的。但是就 11ms 还不是很夸张呀。

Re: [已解决]citx 在 KDE 中启动慢

我删除了`~/.cache`和`~/.config`中有关kde的文件以及家目录中的一个`.Xmodmap`，重启电脑发现fcitx5可以正常运行了。
谢谢你的帮助
