Problem with desktop background and items
- Login o registrati per inviare commenti
Hi everybody,
since last week's wednesday i have a strange problem. Desktop background is black. I can switch it to whatever picture i have, but after restarting the computer it's black again. And the desktop files are always put in the same order. I can change the order, but after restarting they are like before.
What could have provoked this? There might have been a small update the day before it happened, but nothing else.
This is Trisquel mini.
I know Mini runs LXDE, but it may be a similar issue. Maybe this can work: https://unix.stackexchange.com/questions/151471/desktop-background-appears-black-when-using-xfce
There's this that could help as well: https://bbs.archlinux.org/viewtopic.php?id=158852

Was this one of the stock Trisquel backgrounds? What does the background of your login screen look like?
Thanks, but the xfce thing doesn't seem appropriate to me, from the way that it was solved.
The other two links are about changing a line in /etc/xdg/lxsession/LXDE/autostart.
That line should, according to those old posts for other distros, be:
@pcmanfm --desktop
In my case it's: @pcmanfm --desktop --profile LXDE
Does that make it wrong?
In ~.config/lxsession/Trisquel-mini there's the line
@pcmanfm --desktop --profile Trisquel-mini
I can right-click on the desktop and change settings, but after restarting it's gone.
It's not about stock Trisquel backgrounds but about personal jpg files.
Login screen has the default Trisquel background.
Now i see: When i click on Change User and log back in, the desktop is how i changed it and how it should be. When i choose Log Out instead and log back in, settings are gone and background is black, files are in a different order, too.
At login i can choose between LXDE session and Trisquel-mini session (default). Should i change the first mentioned code line, where it says "profile LXDE", to "profile Trisquel-mini", as in the config file?

Are you sure you are not logging in as a guest? It happens to me sometimes if I didn't turn off the touchpad and I accidentally scroll up to guest from my normal user
Now i've messed it up.
Current situation: I'v even lost the desktop panel. I can get it with the command lxpanel and then configure it. But after restarting the computer it's gone. And when shutting down via menu i don't get the dialogue with the Trisquel logo but with the Lxde logo. The panel also has the default Lxde appearance.
Plus: When i log out, i can not log back in. I get the Trisquel background (not black; the login background just stays) but only with Openbox functionality and nothing on the desktop.
Any ideas on how to solve the login problem and get my original panel back?
What i did:
After being asked about file permissions i remembered an issue (https://trisquel.info/en/issues/15394) that i (and others) had with policykit-packages. For authentication matters we needed to reconfigure that, either by installing the package lxpolkit or by using the package policykit-gnome... I thought i have lxpolkit installed and changed the according line in the above mentioned file ~.config/lxsession/Trisquel-mini from policykit-gnome... to lxpolkit. As this whole issue might have to do with /etc/xdg/lxsession/LXDE/autostart, too, where that line also exists, but where root privileges are needed, i did that change in the config file via gksudo pcmanfm. That messed it up. I could undo the change, but now it's as it is. I've found out that i don't even have lxpolkit installed. I used that package on my other computer.
Does anybody have a clue how to solve this? I guess it can be changed in some settings, because i have copied the home folder via deja dup to another computer with Trisquel mini that worked fine before and now it is the same as here.

Before answering the following list of questions, have you tried the following:
Create a new, regular, user. Then log in as that new user. Do you have the same problems as the new user?
Just to clarify the details of your system:
0.) "i have copied the home folder via deja dup to another computer with Trisquel mini that worked fine before" Is that what you have done here? You copied your home folder from another system to the one you are now having problems with? What happens when you use the default home folder given for a new user?
1.) What version of Trisquel are you using? Is it Trisquel-Mini? If so, what version?
2.) Did you choose all the defaults at installation? In other words, if I went through the installer on your hardware and accepted every single default choice would I get your exact setup?
3.) After installation, did you make any major system changes? Are you using the same window manager? What window manager is that? You mentioned Openbox, is that the default, or did you add that?
4.) Are you using the same DE as the default? Was the default XFCE?
5. Has this installation worked before? If so, what are some of the recent changes that you have made?
6.) Has everything worked since your last big change?
Basically, what changes have you made to the default Trisquel-Mini install?
As mentioned in the original posting, the problem arose out of nothing, on the topical install of Trisquel mini, without ever having done any system changes (default DE is LXDE). I made it worse then, as described.
I guess i can change it back somehow because i copied my home folder to another computer (accidentally including the hidden folders), pretty much exactly the same install as here, and now i have the same problem on the other computer, too. So it must be something in the config files, i guess.

Then the only thing I can suggest to try at this point is creating a new user and seeing if things work as a new user. If it does, that will help troubleshoot what to do with your current user.
Probably. The problem is "which one". I do not know (I have never used LXDE) but it probably is below ~/.config. You can even move/rename that entire directory and see if that solves you problem. If so, you can then restore some of the folder ~/.config used to contain (if you do not want to reconfigure by hand many applications).
