The cause
Most likely, the issue is the result of a bug (related to the video driver). I assume the second screen is not remembered somehow, and "virtually" re- connected in a rather late stage in the start up (log in) process.
Work around
As often, even if it is a bug, it doesn't mean we cannot find a work around. If we:
- can make some kind of a snapshot of the current icon positions on log out
- restore the icon positions after the second screen appears correctly after restart (log in)
effectively the bug is worked around.
How to read the icon position on the desktop
You can get the position on the desktop of an icon by the command:
gvfs-info -a 'metadata::nautilus-icon-position' '<file>'
This will a.o. output the coordinates of the icon on your desktop, which we can save into a file. If we make a snapshot this way of your desktop before shutting down the computer, we can subsequently restore the icon's position afterwards, with the command:
gvfs-set-attribute -t string '<file>' 'metadata::nautilus-icon-position' '500,500'
(for example)
A script to take such a snapshot, and restore the icon layout (depending on the argument) would be:
#!/usr/bin/env python3
import subprocess
import os
import sys
# --- set your localized desktop name below:
dt_name = "Bureaublad"
# ---
# used strings & definitions
val = " 'metadata::nautilus-icon-position' "
search = "gvfs-info -a"+val
set_val = "gvfs-set-attribute -t string "
home = os.environ["HOME"]
dt_dir = home+"/"+dt_name
datafile = home+"/.desktop_items.txt"
arg = sys.argv[1]
get = lambda cmd: subprocess.check_output(["/bin/bash", "-c", cmd]).decode("utf-8")
def snapshot():
try:
os.remove(datafile)
except FileNotFoundError:
pass
dt_items = os.listdir(dt_dir)
dt_data = []
for f in [f for f in dt_items if all([not f.startswith("."), not f.endswith("~")])]:
f = '"'+f+'"' if f.count(" ") > 0 else f
file = dt_dir+"/"+f
cmd = search+file
try:
loc = [int(n) for n in get(cmd).split()[-1].split(",")]
# loc[0] = loc[0] - screen_pos[0]; loc[1] = loc[1] - screen_pos[1]
loc = (",").join([str(n) for n in loc])
open(datafile, "a+").write(file+"|||"+loc+"\n")
except:
pass
subprocess.Popen(["/bin/bash", "-c", "notify-send 'A snapshot was taken'"])
def restore():
items = [l.strip().split("|||") for l in open(datafile).readlines()]
for item in items:
try:
xy = [int(n) for n in item[1].split(",")]
move_to = (",").join(str(n) for n in [xy[0], xy[1]])
command = set_val+item[0]+val+move_to
subprocess.Popen(["/bin/bash", "-c", command])
except:
pass
subprocess.Popen(["/bin/bash", "-c", "notify-send 'Click on the desktop and press F5'"])
if arg == "snapshot":
snapshot()
elif arg == "restore":
restore()
To use it:
- Copy the script into an empty file, save it as
restore_desktop.py
In the head section of the script, in the line:
# --- set your localized desktop name below:
dt_name = "Desktop"
# ---
set the localized name of your desktop folder ("Bureaublad" in Dutch)
To take a snapshot of the current icon layout, run the command:
python3 /path/to/restore_desktop.py snapshot
To restore a previously taken snapshot:
python3 /path/to/restore_desktop.py restore
then click on the desktop and press F5 to refresh the desktop.
To use the script in our situation would however take a few additions
The desktop still needs to be refreshed from the command line to actually apply the restore of the icons. This can be done by either restarting nautilus, or press F5 with the desktop in front. Since we use it on startup, the first option might be the most elegant one.
We need to take a snapshot on log out as the current user to make sure the last icon layout is recorded into a snapshot. So far, I could not find a way to do that.
However, as always, there is a workaround. If we include the command
gnome-session-quit --poweroff
in our script, we can simply call the script (with the right arguments) to include the shutdown procedure and take the snapshot.
- Then to make sure the restored snapshot is applied we can include the restart of nautilus in the script.
The solution
The final script then becomes:
#!/usr/bin/env python3
import subprocess
import os
import sys
import time
# --- set your localized desktop name below:
dt_name = "Desktop"
# ---
# used strings & definitions
val = " 'metadata::nautilus-icon-position' "
search = "gvfs-info -a"+val
set_val = "gvfs-set-attribute -t string "
home = os.environ["HOME"]
dt_dir = home+"/"+dt_name
datafile = home+"/.desktop_items.txt"
arg = sys.argv[1]
get = lambda cmd: subprocess.check_output(["/bin/bash", "-c", cmd]).decode("utf-8")
def snapshot():
# remove the previous snapshot
try:
os.remove(datafile)
except FileNotFoundError:
pass
# list the items on the desktop, look up their positions
dt_items = os.listdir(dt_dir)
dt_data = []
for f in [f for f in dt_items if all([not f.startswith("."), not f.endswith("~")])]:
f = '"'+f+'"' if f.count(" ") > 0 else f
file = dt_dir+"/"+f
cmd = search+file
try:
loc = [int(n) for n in get(cmd).split()[-1].split(",")]
loc = (",").join([str(n) for n in loc])
open(datafile, "a+").write(file+"|||"+loc+"\n")
except:
pass
# notify that a snapshot was taken
subprocess.call(["/bin/bash", "-c", "notify-send 'A snapshot was taken'"])
# send the command to shutdown
subprocess.Popen(["gnome-session-quit", "--power-off"])
def restore():
# wait for 20 seconds for the desktop to be fully loaded and the screen to be found
time.sleep(20)
# read the snapshot file
items = [l.strip().split("|||") for l in open(datafile).readlines()]
for item in items:
try:
# place the icon(s) acoording to the remembered position(s)
xy = [int(n) for n in item[1].split(",")]
move_to = (",").join(str(n) for n in [xy[0], xy[1]])
command = set_val+item[0]+val+move_to
subprocess.Popen(["/bin/bash", "-c", command])
except:
pass
# restart nautilus
subprocess.call(["killall", "nautilus"])
subprocess.Popen(["nautilus"])
# send notification
subprocess.Popen(["/bin/bash", "-c", "notify-send 'Icon positions were restored'"])
if arg == "snapshot":
snapshot()
elif arg == "restore":
restore()
How to use
- Copy the script into an empty file, save it as
restore_icons.py
In the head section of the script, set the appropriate (localized) name of the Desktop folder:
# --- set your localized desktop name below:
dt_name = "Desktop"
# ---
Test- run the script by running the command:
python3 /path/to/restore_icons.py snapshot
A snapshot of the current layout will be take. De shut down menu appears on your desktop, but cancel it by clicking outside the menu on your desktop.
Then deliberately mess around with your icons (positions) on your desktop.
Finaly, run the script again with another argument:
python3 /path/to/restore_icons.py restore
Wait for 20 seconds (see Note at the bottom why that is included in the script) and your desktop icons will be restored to how it was before you took the snapshot.
If all works fine, add a shortut key: Choose: System Settings > "Keyboard" > "Shortcuts" > "Custom Shortcuts". Click the "+" and add the command:
python3 /path/to/restore_icons.py snapshot
This will be the shortcut you need to use, to shut down your computer.
Add the restore command to Startup Applications: Dash > Startup Applications > Add. Add the command:
python3 /path/to/restore_icons.py restore
Now 20 seconds after startup (log in), your icons will be exactly like you left them on shut down.
Note
The 20 seconds break is to make sure the second monitor is found and reconnected before the restore command runs.
