Hi,
Is there any way to fix the position of my second panel? Every time I connect an external monitor, the position of my second panel moves around a bit. My guess is that this is because X11 recognizes the monitors as a big one screen; so the absolute position of the panel needs to be changed when I connect an additional monitor.
I was wondering if there is a way to fix this behavior without writing a workaround in bash.

What version of Xfce are you running?
There should be an option in the panel properties where you can specify which monitor to use for the panel.

I am currently using xfce 4.18 on Arch Linux with 6.4.8-arch1-1 Kernel.
I already selected the output option as primary, but it doesn't fix the problem.

In the first tab of panel properties you have a checkbox "lock panel", do you have it checked?

Also, do you have a primary display defined in Settings Manager > Display? Or alternatively, select a specific monitor instead of Primary.

The 'lock panel' option is already checked, and my built-in laptop display is already marked as the primary display, but the problem still persists.
Could this be a specific issue with the Nvidia graphics card?

That is odd.
If you re-position the laptop screen so it aligns with the bottom of the Samsung display, does the problem still exist?

It seems to be that is the case.
I also have installed KDE plasma (wayland) desktop environment on my laptop. Is there any chance that this might be causing this issue?

I mean to try it flush to the bottom:

Do you have scaling enabled on the larger monitor?
What do the following commands return (with both monitors enabled):
xfconf-query -c displays -lv
xrandr -q

I'm not sure. When Xfce is running, do you have any KDE services running as well?
Edit:
Can you also try running xfce4-panel in debug mode. Start with the external monitor disconnected, then:
xfce4-panel -q
PANEL_DEBUG=1 xfce4-panel
...then connect the second monitor. Post back all the debug output.

I tried that display configuration and could not see any difference. The panel still moves around.

No I didn't enable scaling on the larger monitor.

Can you also try running xfce4-panel in debug mode. Start with the external monitor disconnected, then:xfce4-panel -q PANEL_DEBUG=1 xfce4-panel
...then connect the second monitor. Post back all the debug output.

I've been testing this and can't replicate this problem on my system, however, both my laptop and external monitors are the same size. You're debug output above is different from mine, but I'm not sure if that's related to the difference in monitor sizes.
Could this be a specific issue with the Nvidia graphics card?
I also don't have an nvidia card nor do I have much experience with nvidia cards. Is your nvidia config set up somehow so that it sees both as one monitor (as opposed to one workspace)? Hopefully that makes sense...

I think it is entirely possible that this is Nvidia specific issue.
So, I tried to write a workaround in bash, but editing the xfce-4panel.xml file and restarting xfce4-panel doesn't seem to change the position of the panel.
If you don't mind, could you let me know what I can do better in the script?
# detect how many screens are connected (and location of 2nd screen)
numOfConnectedMonitors=$(xrandr | grep " connected" | wc -l)
# based on the screen information, fix the visual position of the panel on the primary screen
if [ $numOfConnectedMonitors -gt 1 ]
then
xPrimaryRes=$(xrandr | grep "primary" | awk '{print $4}' | grep -o -P '\d{4}x' | sed 's/x//')
yPrimaryRes=$(xrandr | grep "primary" | awk '{print $4}' | grep -o -P 'x\d{4}' | sed 's/x//')
xExternalRes=$(xrandr | grep "primary" | awk '{print $4}' | grep -o -P '\+\d{4}' | sed 's/\+//')
yExternalRes=$(xrandr | grep "primary" | awk '{print $4}' | grep -o -P '\+\d{3}$' | sed 's/\+//')
gabFromBottom=30
xPanelPos=$(echo $xPrimaryRes+$xExternalRes-$xPrimaryRes/2 | bc)
yPanelPos=$(echo $yPrimaryRes+$yExternalRes-$gabFromBottom | bc)
configFile="$HOME/.config/xfce4/xfconf/xfce-perchannel-xml/xfce4-panel.xml"
# targets the second panel
lineNumPos=$(grep -n '<property name="position" type="string"' $configFile | tail -n 1 | awk '{print $1}' | sed 's/://')
# echo $lineNumPos
# change pos
PosString=$(echo "\t<property name=\"position\" type=\"string\" value=\"p=0;x=$xPanelPos;y=$yPanelPos\"\/\>")
sed -i "$lineNumPos s/.*/$PosString/" $configFile
# restart xfce4-panel
xfce4-panel -r

Instead of editing the xml file, how about just issuing xfconf-query commands (the effect would be immediate)? It would target the "/panels/panel-X/position" variable. As an example, my panel 2:
$ xfconf-query -c xfce4-panel -p /panels/panel-2/position
p=7;x=30;y=144
If I set p to 6, it moves to the top left corner.
The "p" is the position and is defined as:
p=0: free position
p=1: right border
p=2: upper right corner
p=4: bottom right corner
p=5: left border
p=6: upper left corner
p=7: middle-left
p=8: bottom left corner
p=9: top right corner ??
p=10: middle right ??
p=11: upper border
p=12: bottom border
If p is one of 2,4,6,8, it is in one of the corners and the x and y values are ignored.
If p is one of 1,5 (side border), the y value is used.
If p is one of 11,12 (top/bottom border), the x value is used.
Only in a situation where p=0 (free-standing) are both x and y used.
If you could post back the results of:
xfconf-query -c xfce4-panel -lv | grep position
...with the panel in the correct position for both single monitor and dual monitor, I can help you figure out the values if you need assistance.

Thank you,
It turns out that the only thing I needed to do was to set p=10 on the coordinate.
Now, regardless of whether the second monitor is connected or not, the second panel stays at the bottom center of the primary screen.

Interesting. Too bad we didn't get the previous value - maybe it wasn't set to the border edge and that why it was moving (value would have been 0).

Actually, I still have the previous value. It was p=0;x=4828;y=1250.
And yes, the p value was zero just like you have already mentioned.
I want to thank you for the support once more.
