[SOLVED] Display Settings launches when monitor wakes from sleep

JayM · 2021-03-29 02:41:25

I rebuilt my computer with a new motherboard, processor and RAM then I reinstalled my OS, MX-Linux 19.3 AHS, from a personal snapshot I'd made on my old system. Ever since, whenever the monitor shuts off from being idle then comes back on, or if I turn the monitor off and on, the Display Settings window launches by itself. However when I created a new user and logged in as it the issue doesn't happen so it must be something specific to my user settings, but I didn't change any settings regarding the display. Can you tell me what I should look for? Thanks.

BTW it's the main display settings screen that pops up, not the minimal one where you configure multiple monitors. I only have one monitor connected anyway.

I just looked at ~/.xsession-errors and I'm finding this:

I wonder which application/process is generating this? Do you get the same message on your second user account?

Can you post back your keyboard shortcuts?

xfconf-query -c xfce4-keyboard-shortcuts -lv

I've seen an instance before where a newly detected monitor (on resume from suspend in this case) was emitting and Xorg DISPLAY event (never did find out why) and there was a keyboard shortcut set to respond to the event. Looks like this might be happening here. In which case, a workaround is to delete that keyboard shortcut.

My new user account gets the libpager messages in .xsession-errors but not the DISPLAY_REMOVED and DISPLAY_ADDED ones.

I saw the other thread about the person whose Display Settings would launch every 30 seconds or so and I looked at my Settings -> Keyboard, Application Shortcuts tab and didn't see the shortcut you suggested he delete, but

Catfish isn't finding any files in my home directory containing XF86Display though. (Plus like I mentioned it's not the minimal version that pops up, but the normal version you get when you run Settings -> Display from the menu.)

/commands/default/XF86Display xfce4-display-settings --minimal

Can you change the executable command for this entry to something like "mousepad" so we can see if mousepad starts suddenly popping up? There should be an entry in your keyboard settings for this. If you need to change it manually, only do so after you've restarted and before you log in to Xfce.

Also, the "DISPLAY_REMOVED and DISPLAY_ADDED" entries are being added by something. If you could figure out by what it would be helpful. Start with the differences between the 2 autostart applications for both users.

Re: keyboard shortcuts, I couldn't change the one entry for the Display key as my keyboard doesn't have one, so I just deleted it, logged out and in, and tested. No difference. I also temporarily changed the one for Super+p to launch Featherpad. Still no change (Featherpad didn't auto-launch when I turned my display off and on, but display settings did.)

Re: autostart apps, I compared mine to those of the new user and moved the ~/.config/autostart/*.desktop files that I have and "he" doesn't to a temp directory, one at a time, logging out/in and testing each time. No difference.

I haven't modified my .profile or .bashrc files to make them load anything either. Just in case one of the default autostart .desktop files had gotten modified I copied the new user's ones and pasted them in my directory, telling Thunar to replace all, then chowned them to me, logged out/in, tested: no difference. Hmmm...

Try this.

Next time it pops up, in a terminal window run:

ps -ef | grep xfce4-display

In the result, the second number in the string is the PID of the parent window. Then run:

ps -ef | grep PID_FROM_ABOVE

...and lets see who the parent is.

Could something be respawning the daemon? (That sounds like something from Lovecraft!)

We're getting somewhere. It is the minimal dialog that is displaying. And it's being launched by xfsettingsd.

Looking into the code I find:

/* Start the minimal dialog according to the user preferences */
if (changed && xfconf_channel_get_bool (helper->channel, NOTIFY_PROP, FALSE))
xfce_spawn_command_line_on_screen (NULL, "xfce4-display-settings -m", FALSE,
FALSE, NULL);

...which means its hard-coded to start when NOTIFY_PROP is enabled. You will find this on the advanced tab in the Display settings, labelled "Configure new displays when connected". Is this currently selected? If so, un-select it and see if that makes a difference.

If it does make a difference, you may need to create a profile for your current external monitor so that it isn't identified as new each time.

JayM · 2021-03-31 02:49:45

That solved it! I disabled display configuration and tested by turning my monitor off and on, no display settings window. I created a profile for my display, re-enabled display configuration when new displays are connected, tested again: no display settings window! Creating the profile fixed the annoyance. Thanks!
