2014-04-23 解决搜狗输入法Ubuntu 14.04下黑块状态条

这有帮助吗?

搜狗的Linux输入法正式版发布之时,恰好Ubuntu 14.04 LTS也刚刚发布正式版。尝试安装搜狗的Linux输入法之后,出现了一个小小的问题:输入法状态条是一个黑色块。

我的Linux桌面用的是i3平铺式桌面管理器,多显示器环境下非常好用,。除此之外,GUI底层用的是KDE。

做了一番功课之后,结果发现因为搜狗要支持皮肤,所以那个状态条是半透明状态的。而我目前的默认环境下不支持compositor窗口管理器,无法处理半透明窗口的效果,于是就只能显示一个黑色块。

解决办法是安装,以支持窗口的半透明效果。Ubuntu默认情况下没有可用的APT源,有两种办法安装:一个是从源码编译(不赘述),另外一个是使用一个第三方的源。

安装第三方源并安装compton

sudo apt-add-repository ppa:richardgv/compton
sudo apt-get update && sudo apt-get install compton

配置compton

编辑文件 ~/.compton.conf,输入如下内容

backend = "glx";
paint-on-overlay = true;
glx-no-stencil = true;
glx-no-rebind-pixmap = true;
vsync = "opengl-swc"; 

# These are important. The first one enables the opengl backend. The last one
# is the vsync method. Depending on the driver you might need to use a
# different method.
# The other options are smaller performance tweaks that work well in most
# cases.
# You can find the rest of the options here:
# https://github.com/chjj/compton/wiki/perf-guide, and here:
# https://github.com/chjj/compton/wiki/vsync-guide

# Shadow
shadow = false;          # Enabled client-side shadows on windows.
no-dock-shadow = true;      # Avoid drawing shadows on dock/panel windows.
no-dnd-shadow = true;       # Don't draw shadows on DND windows.
clear-shadow = true;        # Zero the part of the shadow's mask behind the window (experimental).
shadow-radius = 7;      # The blur radius for shadows. (default 12)
shadow-offset-x = -7;       # The left offset for shadows. (default -15)
shadow-offset-y = -7;       # The top offset for shadows. (default -15)
shadow-exclude = [
    "! name~=''",
    "n:e:Notification",
    "n:e:Plank",
    "n:e:Docky",
    "g:e:Synapse",
    "g:e:Kupfer",
    "g:e:Conky",
    "n:w:*Firefox*",
    "n:w:*Chrome*",
    "n:w:*Chromium*",
    "class_g ?= 'Notify-osd'",
    "class_g ?= 'Cairo-dock'",
    "class_g ?= 'Xfce4-notifyd'",
    "class_g ?= 'Xfce4-power-manager'"
];                                                                                                                                                                                                            

# The shadow exclude options are helpful if you have shadows enabled. Due to
# the way compton draws its shadows, certain applications will have visual
# glitches
# (most applications are fine, only apps that do weird things with xshapes or
# argb are affected).
# This list includes all the affected apps I found in my testing. The "!
# name~=''" part excludes shadows on any "Unknown" windows, this prevents a
# visual glitch with the XFWM alt tab switcher.                                                                                                                                                               

# Fading
fading = true; # Fade windows during opacity changes.
fade-delta = 4; # The time between steps in a fade in milliseconds. (default 10).
fade-in-step = 0.03; # Opacity change between steps while fading in. (default 0.028).
fade-out-step = 0.03; # Opacity change between steps while fading out. (default 0.03).
#no-fading-openclose = true; # Fade windows in/out when opening/closing

detect-client-opacity = true; # This prevents opacity being ignored for some apps. For example without this enabled my xfce4-notifyd is 100% opacity no matter what.

# Window type settings
wintypes:
{
  tooltip = { fade = true; shadow = false; };
};

重点是其中 shadow 一项的值设置为 false 。

自启动

最后,修改i3配置文件 ~/.i3/config,在最后加入下面的代码,实现自动启动compton和搜狗输入法

# auto start commands
exec --no-startup-id fcitx -r
exec --no-startup-id fcitx-qimpanel
exec --no-startup-id compton -b

安装完成了,系统也顺便带了半透明和淡入淡出效果。

强烈推荐
