No need to run the desktop with Xrdb - Much better perf with Xephyr!

Install Xephyr and Xfce4 first.

$ cat ~/launch_desktop.xfce4 

#!/bin/bash
echo "Current DISPLAY=$DISPLAY"
echo "Finding a free DISPLAY number"
for i in $(seq 1 20);
do
    DISPLAY=":$i" xset q >/dev/null 2>/dev/null ; RET=$?
    if [ "$RET" -ne "0" ] ; then
        export NEW_DISPLAY=":$i"
        break;
    fi
done
echo "Starting Xephyr and a new desktop on DISPLAY=$NEW_DISPLAY"
export XEPHYR_ID 
export DISPLAY
{
    Xephyr "$NEW_DISPLAY" -title "XFCE4 Desktop for $USER" -once -screen 2560x1080 -resizeable >/dev/null 2>/dev/null & XEPHYR_ID="$!" 
    DISPLAY="$NEW_DISPLAY" startxfce4 >/tmp/launch_desktop_xfce4.log 2>&1
    kill $XEPHYR_ID 2>/dev/null

Better:

#!/bin/bash
echo "Current DISPLAY=$DISPLAY"
echo "Finding a free DISPLAY number"
for i in $(seq 1 20);
do
    DISPLAY=":$i" xset q >/dev/null 2>/dev/null ; RET=$?
    if [ "$RET" -ne "0" ] ; then
        export NEW_DISPLAY=":$i"
        break;
    fi
done
echo "Starting Xephyr and a new desktop on DISPLAY=$NEW_DISPLAY"
export XEPHYR_ID 
export DISPLAY

nohup Xephyr "$NEW_DISPLAY" -title "XFCE4 Desktop for $USER" -once -screen 2560x1080 -resizeable >/dev/null 2>/dev/null & XEPHYR_ID="$!" &
sleep 2
DISPLAY="$NEW_DISPLAY" nohup startxfce4 >/tmp/launch_desktop_xfce4.log 2>&1 &
disown -a

• Added a fg option - needed by a window shortcut?
• disown added
• added more cleanup arguments to Xephyr server

$ cat ~/launch_desktop.xfce4
#!/bin/bash
echo "Current DISPLAY=$DISPLAY"
echo "Finding a free DISPLAY number"
for i in $(seq 1 20);
do
    DISPLAY=":$i" xset q >/dev/null 2>/dev/null ; RET=$?
    if [ "$RET" -ne "0" ] ; then
        export NEW_DISPLAY=":$i"
        break;
    fi
done
echo "Starting Xephyr and a new desktop on DISPLAY=$NEW_DISPLAY"
export XEPHYR_ID 
export DISPLAY
if [ "$1" == "-fg" ] ; then
    Xephyr "$NEW_DISPLAY" -title "XFCE4 Desktop for $USER" -once -reset -terminate -screen 2560x1080 -resizeable >/dev/null 2>/dev/null & XEPHYR_ID="$!" 
    DISPLAY="$NEW_DISPLAY" startxfce4 >/tmp/launch_desktop_xfce4.log 2>&1
    kill $XEPHYR_ID 2>/dev/null
else
    {
        Xephyr "$NEW_DISPLAY" -title "XFCE4 Desktop for $USER" -once -reset -terminate -screen 2560x1080 -resizeable >/dev/null 2>/dev/null & XEPHYR_ID="$!" 
        DISPLAY="$NEW_DISPLAY" startxfce4 >/tmp/launch_desktop_xfce4.log 2>&1
        kill $XEPHYR_ID 2>/dev/null
    } &
    disown -a

Hello @chuckmarcotte,

Very good idea, I have also seen another one with XWayland, both take advantage of WSLg.

I need take time to test them an include them in the install_desktop script

Thanks

I don't know why I though you were in the Fedora GitHub, not in Pengwin. This can be added to the Pengwin setup.
