作者：seniors sudo apt-get install xcompmgr transset 编辑 /etc/X11/xorg.conf 查找: Section “Device” Identifier “Intel Corporation 82845G/GL[Brookdale-G]/GE Chipset Integrated Graphics Device” Driver “i810” BusID “PCI:0:2:0” Option “RenderAccel” EndSection 添加: Option “RenderAccel” eexp: 如果已经安装了驱动，比如nvidia。这此行一般自动添加了。写法如下： Option “RenderAccel” “true” 在末尾加入: Section “Extensions” Option “Composite” “Enable” Option “RENDER” “Enable” EndSection 再在用户目录里添加 .gnomerc 添加 xcompmgr -c -f 重启就可以看到阴影效果 要透明只要在终端里运行 transset 0.5 会出现一个十字鼠标，点击窗口就可以使该窗口透明 其中 0.5 是指透明度，如果是 0 的话你就看不到窗口了 http://forchheimer.se/transset-df/ 这个版本可以带参数 “ -h, –help display this message\n”); “ -t, –toggle force toggle of opacity\n”); “ -c, –click select by clicking on window (default)\n”); “ -p, –point select the window currently under the cursor\n”); “ -n, –name NAME select by name, NAME is matched as regular expression\n”); “ –no-regex don’t use regular expression for matching name\n”); “ -i, –id select by window id\n”); “ –inc increase by the given opacity\n”); “ –dec decrease by given opacity\n”); “ -m, –min OPACITY minimum possible opacity (default = 0)\n”); “ -x, –max OPACITY maximum possible opacity (default = 1)\n”); “ -v, –verbose print some debug info\n”); “ -V, –version print version number\n”);
