2014-04-23 解决搜狗输入法Ubuntu 14.04下黑块状态条
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。
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。
sudo apt-add-repository ppa:richardgv/compton
sudo apt-get update && sudo apt-get install 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 。
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。
