After I set wallpaper on an external monitor, the desktop-preference program crashed by reporting <code>\"desktop manager is not active\"<\/code> and I got a wrongly configured wallpaper as an accompanying result. The link <a href=\"https:\/\/askubuntu.com\/questions\/516810\/lubuntu-desktop-preferences-is-gone\">here<\/a> said that this is because the pcmanfm failed to draw desktop at startup. Manually redraw desktop by executing:<br \/>\n<code>pcmanfm --desktop &amp;<\/code><br \/>\nwill restore desktop-preference. I planned to add this command to autostart menu and found that there was already a similar command:<br \/>\n<code>pcmanfm --desktop --profile LXDE<\/code><br \/>\nObviously, this is the failed command which caused the trouble. It seems that an LXDE profile config file related to this command was corrupted.<br \/>\nI finally found this desktop-items-0.conf file under<span style=\"color: #3366ff;\"> <code>\/home\/user\/.config\/pcmanfm\/LXDE<\/code><\/span> and modified the wallpaper related settings in it to default. To be specific:<\/p>\n<p><code>wallpaper_mode=crop<br \/>\nwallpaper=\/usr\/share\/backgrounds\/images\/default.png<\/code><\/p>\n<p>Actually, I copied these 2 lines from a desktop-items-1.conf file in the same folder.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>I&#8217;ve got some memory-intensive works to do recently.
