在Xubuntu中屏幕撕裂，Ubuntu没问题
我在我的一个旧桌面上安装了Ubuntu 14.04和Xubuntu 16.04。
虽然两者都工作正常，但我在Xubuntu中拖动窗户时会遇到屏幕撕裂。 但是，我没有在Ubuntu上体验过它。
它使用的是主板的内置AMD图形芯片。
注意：对于带有GTX650显卡的主桌面，这种情况也适用…
在这一点上，我认为它与Untiy是3D DE有关，而XFCE是2D DE …
注意：这些指示已从Duncan Lock博客的原始资料中删除。
-
禁用XFCE的内置合成器：
-
打开终端，然后运行以下命令：
sudo apt-get update sudo apt-get install compton cd ~/.config nano compton.conf
-
将其粘贴到Nano中（有关注释版本，请参见此处 ）：
backend = "glx"; glx-no-stencil = true; glx-copy-from-front = false; glx-swap-method = "undefined"; shadow = true; no-dnd-shadow = true; no-dock-shadow = true; clear-shadow = true; shadow-radius = 5; shadow-offset-x = -5; shadow-offset-y = -5; shadow-opacity = 0.5; shadow-exclude = [ "! name~=''", "name = 'Notification'", "name = 'Plank'", "name = 'Docky'", "name = 'Kupfer'", "name = 'xfce4-notifyd'", "name *= 'VLC'", "name *= 'compton'", "name *= 'Chromium'", "name *= 'Chrome'", "name *= 'Firefox'", "class_g = 'Conky'", "class_g = 'Kupfer'", "class_g = 'Synapse'", "class_g ?= 'Notify-osd'", "class_g ?= 'Cairo-dock'", "class_g ?= 'Xfce4-notifyd'", "class_g ?= 'Xfce4-power-manager'" ]; shadow-ignore-shaped = false; menu-opacity = 1; inactive-opacity = 1; active-opacity = 1; frame-opacity = 1; inactive-opacity-override = false; alpha-step = 0.06; blur-background-fixed = false; blur-background-exclude = [ "window_type = 'dock'", "window_type = 'desktop'" ]; fading = true; fade-delta = 4; fade-in-step = 0.03; fade-out-step = 0.03; fade-exclude = [ ]; mark-wmwin-focused = true; mark-ovredir-focused = true; use-ewmh-active-win = true; detect-rounded-corners = true; detect-client-opacity = true; refresh-rate = 0; vsync = "opengl-swc"; dbe = false; paint-on-overlay = true; sw-opti = false; unredir-if-possible = true; focus-exclude = [ ]; detect-transient = true; detect-client-leader = true; wintypes: { tooltip = { fade = true; shadow = false; opacity = 0.85; focus = true; }; };
- 按CTRL + X ，然后按Y ，然后按Enter键保存并退出。

现在，运行以下命令：
compton你的屏幕会闪烁，你将不再有屏幕撕裂！
-
最后，只需将其添加到您的启动应用程序：
