Cannot find gtk-query-immodules for gtk 3

    **Cannot find fcitx im module for gtk 3.**、

解决办法：

fcitx-diagnose #缺少什么装什么
pacman -S fcitx-gtk2 fcitx-gtk3 fcitx-qt4 fcitx-qt5

把这个复制到.profile

export GTK_IM_MODULE=fcitx
export QT_IM_MODULE=fcitx
export XMODIFIERS=@im=fcitx

manjaro make

make[1]: Entering directory '/usr/lib/modules/4.19.12-2-MANJARO/build'
make[1]: * No rule to make target 'modules'. Stop.
make[1]: Leaving directory '/usr/lib/modules/4.19.12-2-MANJARO/build'
make: * [Makefile:1923: modules] Error 2

这个原因大多是由于linux内核的header未安装正确

uname -r
pacman -S linux linux419-headers
reboot # need reboot

最近spring cloud 报错：com.netflix.hystrix.exception.HystrixRuntimeException: UserClient#listById(List) failed and no fallback available.

解决办法：加长hystrix 命令的超时时间

 hystrix:
  command:
    default:
      execution:
        isolation:
          thread:
            timeoutInMilliseconds: 6000
        timeout:
          enabled: false

Manjaro i3 error X Error of failed request: BadWindow (invalid Window parameter) Major opcode of failed request: 20 (X_GetProperty)

kafka报错： org.apache.kafka.clients.consumer.CommitFailedException: Commit cannot be completed since the group has already rebalanced and assigned the partitions to another member. This means that the time between subsequent calls to poll() was longer than the configured max.poll.interval.ms, which typically implies that the poll loop is spending too much time message processing. You can address this either by increasing the session timeout or by reducing the maximum size of batches returned in poll() with max.poll.records.

这个是因为：一个consumer在生产消息，另一个consumer在消费它的消息，他们不能在一个groupid 下面，更改其中一个的group id 即可
