2 network icons on taskbar - Lubuntu 18.04.5

[Piotr]

Dear Lubuntu Team,

Sometimes I have problem with issue with duplicate of network icons. They will gone if I will reboot my machine. This issue is arrived randomly. I don't know what is the problem. I noticed this issue also on XFCE environment (Xubuntu 18.04.4 system) and this issue also arrived randomly so I think that can be the same bug to the both environments. I didn't notice this bug on Ubuntu 18.04.5.

This bug is similar to: #1731512 but is different because when I will reboot machine this issue gone itself but randomly arrived with next starts of my system.

ProblemType: Bug
DistroRelease: Ubuntu 18.04.5 LTS
Uname: 5.4.0-66-generic x86_64
Architecture: amd64
CurrentDesktop: LXDE (original from Lubuntu 18.04.5 iso)
SourcePackage: lubuntu-desktop
InstallationMedia: Lubuntu 18.04.5 "Bionic Beaver" - amd64, official iso file
Version of the package: the newest, I always update packages to their newest version

Some outputs from terminal:

1) lsb_release -rd
Description: Ubuntu 18.04.5 LTS
Release: 18.04

2) apt-cache policy pkgname
I will update this information soon, like I said I use newest version. When I will have access to the machine I will update this information.

3) What you expected to happen:

I should not see two network icons on the taskbar on the bottom of the screen. I should see only one network icon. Of course my internet connection works fine. This is only problem with the icons.

4) What happened instead:

Sometimes I can see two network icons. This is randomly so I don't know what is the problem and I can't to tell you steps to reproduce this issue because it is arrived like I said randomly.

I didn't use apport because now I don't have access to this computer (this is not mine machine). I can upload some information in the future. Of course if you want to fix it. Lubuntu 18.04.5 soon will be ended support and I probably will do upgrade to another system or newer Lubuntu.

Yours faithfully,
Piotr

On this video you can see that this issue affected me and is exists. My operating system Lubuntu 18.04.5 with all updates installed. Link to video: https://youtu.be/Dn8WG-O2r10

[Piotr (peterq94)]

No reaction? We have few days to end of support. This mean that this will be not fixed?

[Piotr (peterq94)]

Lubuntu 18.04.5 end of support today so this report is outdated. You can close this but bug is still exist.

[Chris Guiver (guiverc)]

(No this is unlikely to be fixed.... I'm closing a few bugs currently, and can say with an extremely high certainty that the Lubuntu team will not fix this bug, but I won't close it, as bionic still has near two years of life for 'main' packages, and if a wider Ubuntu community member wants to fix it & do the SRU, they can).

FYI: In comment #1 you provided a video to a blanking video screen... That video does not seem to apply to this bug description. The video however grabbed me as I've experienced that issue myself; I just blamed a faulty cable & ignored it, Had I seen a bug about that issue, I would have explored that.

[Piotr (peterq94)]

This issue with blanking video screen affect me also in Ubuntu 18.04.5 and Ubuntu 20.04.1. Not only with Lubuntu. I tried also Fedora 34 and I also had this issue so I think that this is problem with kernel or video driver. How I can help you with find fix for this issue? I can send apport report but only for developer visible.

[Piotr (peterq94)]

This video is for this bug. Not only for blanking video screen. In this video you can see two bug:

- one is video blanking screen
- second is for network manager icon which is on the right bottom corner. You can see two network manager icons instead one icon.

This bug report is about 2 network icons on taskbar on package that is now EOL; nothing will happen.

If the issue also occurs in Lubuntu 20.04 LTS that is supported; the software stack is very different (different desktop for starters) so a new bug should be filed.

> How I can help you with find fix for this issue?

Each issue should be in it's own bug report; unless the issues are linked. This report makes me think of `lxpanel` (given it's notifications appearing on the panel) however that has nothing to do with video/blanking screen... By keeping a report about a single issue, it's easier to work out the package where the bug impacts (lubuntu-meta is a catch all for unknown bugs, as its a package that won't generally be changed post-release)

Once I've worked out the package involved (often with help on bug reports here, or IRC etc; #lubuntu or #lubuntu-devel on libera.chat for lubuntu issues on supported releases) I tend to test in later releases (esp. the latest) and see if it's an issue there. Developers work on the development release (only back-porting security fixes to stable releases) so that's where you get their attention.

If the issue occurs in the development release (currently impish), I then will test in another different environment (eg. for me it's opensuse tumbleweed, debian testing or fedora rawhide; some may be helpful (up-to-date) at times they won't be (eg. debian is currently in freeze), but if you find the issue in other OSes with latest software.. you can then file the bug upstream (where the fix flows down to all distributions). Upstream generally only care about bugs when filed about the latest release of their software

Launchpad allows you to link upstream reports if you get that far, but if you can't find it, just adding the URL to the report is enough so its documented.

This bug was filed on a Lubuntu package, our current wiki page on bug reporting can be viewed at https://phab.lubuntu.me/w/bugs/ (note: it still has the LXDE-LXQt comparison table which may be removed when a change is next required to the document) which is useful to narrow down which Lubuntu package maybe involved.

FYI: To test the latest without requiring an install; you can use dailies (currently created for focal (what will be 20.04.3) and impish (what will be 21.10 on release)) which can be used without installation (https://discourse.lubuntu.me/t/what-is-a-lubuntu-live-session-test/1672 maybe useful if you're not aware of the concept; the thread is still open so if the question is related to testing modern Lubuntu I can be reached there too). Dailies are a great way to test for issues on different hardware too to gain more details for bug reports.

I found this is similar issue like in bug #1761606. This issue I have in Lubuntu 18.04.5 installed on my hard drive. Like you said Lubuntu 18.04.5 is EOL now so this bug probably will be not fixed.

I have question. If I will install LXDE metapackage on focal this mean that lxpanel have still support and this bug can be fixed on focal package for LXDE environment?

[Chris Guiver (guiverc)]

If you need support, I suggest you ask on a support site (see https://discourse.ubuntu.com/t/community-support/709)

If you note the bug you referenced in your last comment (#8), the MATE issue was fixed in hirsute; or what was the then development release (21.04 now) listing the package containing the fix. That fix is unlikely to be back-ported to focal but will exist in future releases (the package used by hirsute is also current in impish) though note I didn't examine to confirm.

I dealt with a support issue days ago and installed LXDE on a box (I think it was a 20.04.3 QA-test install I used; but I forget) and it all looked good to me (but this wasn't the issue I was exploring..) That system was replaced with a impish QA-test install yesterday though.
