编辑：X现在可以通过xscreensaver锁定
嗨！尝试一下，我使用它的效果很好，主要用于游戏！由于它不会由Unity进行管理，因此您可能也会获得很好的结果！
我创建了此脚本，该脚本创建了一个新的X会话并运行命令或打开终端，以便您可以在此处运行它。
openNewX.sh
#!/bin/bash
function FUNCisX1running {
ps -A -o command |grep -v "grep" |grep -q -x "X :1"
}
useJWM=true
useKbd=true
while [[ ${1:0:2} == "--" ]]; do
if [[ "$1" == "--no-wm" ]]; then #opt SKIP WINDOW MANAGER (run pure X alone)
useJWM=false
shift
elif [[ "$1" == "--no-kbd" ]]; then #opt SKIP Keyboard setup
useKbd=false
shift
elif [[ "$1" == "--isRunning" ]]; then #opt check if new X :1 is already running
if FUNCisX1running; then
exit 0
else
exit 1
fi
elif [[ "$1" == "--help" ]]; then #opt show help info
echo "usage: options runCommand"
# this sed only cleans lines that have extended options with "--" prefixed
sedCleanHelpLine='s"\(.*\"\)\(--.*\)\".*#opt" \2"' #helpskip
grep "#opt" $0 |grep -v "#helpskip" |sed "$sedCleanHelpLine"
exit 0
else
#echoc -p "invalid option $1"
echo "PROBLEM: invalid option $1"
$0 --help
exit 1
fi
done
#echo "going to execute: $@"
#runCmd="$1" #this command must be simple, if need complex put on a script file and call it!
runCmd="$@" #this command must be simple, if need complex put on a script file and call it!
#if ! echoc -q -t 2 "use JWM window manager@Dy"; then
# useJWM=false
#fi
# run in a thread, prevents I from ctrl+c here what breaks THIS X instace and locks keyb
if ! FUNCisX1running; then
xterm -e "\
echo \"INFO: hit CTRL+C to exit the other X session and close this window\";\
echo \"INFO: running in a thread (child proccess) to prevent ctrl+c from freezing this X session and the machine!\";\
echo \"INFO: hit ctrl+alt+f7 to get back to this X session (f7, f8 etc, may vary..)\";\
echo ;\
echo \"Going to execute on another X session: $runCmd\";\
sudo X :1"&
fi
#sudo chvt 8 # this line to force go to X :1 terminal
# wait for X to start
while ! FUNCisX1running; do
sleep 1
done
# run in a thread, prevents I from ctrl+c here what breaks THIS X instace and locks keyb
if $useJWM; then
if [[ ! -f "$HOME/.jwmrc" ]]; then
echo '<?xml version="1.0"?><JWM><Key mask="4" key="L">exec:xscreensaver-command --lock</Key></JWM>' \
>$HOME/.jwmrc
#if ! jwm -p; then
# rm $HOME/.jwmrc
# echo ".jwmrc is invalid"
#else
echo "see http://joewing.net/programs/jwm/config.shtml#keys"
echo "with Super+L you can lock the screen now"
#fi
fi
jwm -display :1&
fi
kbdSetup="echo \"SKIP: kbd setup\""
if $useKbd; then
kbdSetup="setxkbmap -layout us"
fi
sleep 2
xscreensaver -display :1&
# setxkbmap is good for games that have console access!; bash is to keep console open!
# nothing
#xterm -display :1&
# dead keys
#xterm -display :1 -e "setxkbmap -layout us -variant intl; bash"&
# good for games!
xterm -display :1 -e "$kbdSetup; bash -c \"$runCmd\"; bash"&
#xterm -display :1 -e "$kbdSetup; bash -c \"$@\"; bash"&
另外，在以下位置添加此内容：compiz配置设置管理器->窗口规则->不可关闭的窗口：
(class=XTerm) & (title=sudo X :1) & (name=xterm)
这将阻止您关闭该终端（使用ctrl + c关闭另一个X会话以及该终端），因为如果关闭“窗口”，它将冻结当前的X会话！
它的优点是您没有Alt + Enter全屏问题，也没有Alt + TAB全屏问题；从Urban Terror（Linux原生）到使用Wine运行的游戏，您都可以以更高的稳定性运行任何3D游戏！甚至某些运行3D游戏的浏览器，例如带有Quake的Firefox！
观察：您可能想要安装jwm软件包，但不是必需的，但是如果您需要在那里进行任何窗口管理，将会有所作为。
PS .：当然可以改进，我的计划是将键盘设置添加到一个选项中，但是我做得很慢；
