I'm pretty sure I've found the root cause of my hibernation problem. Over time, I've occasionnally added new tabs to my current Vivaldi session. Examples are when I've been referred to a new doctor, or subscribed to a new streaming service or racing championship. But I had absolutely no idea how those tabs added up. I'm sure that a good many are duplicates, just added at different times.

58 tabs in one window eventually became 332 tabs in 17 windows!

So little by little, hibernating this laptop became more and more of a job, culminating in my recent issues. Since all these tabs are available on my start page anyway, I've now gone back to my June working set, and will simply grab those less important tabs from the start page if I need to connect with them. The convenience of having them immediately available in the current session just isn't worth the performance hit.

    great troubleshooting! so the browser considered tabs, open or not, as an active connection?

        The upgrade of onedrive caused some issues for me, as the gui client "onedrive-gui" was not upgraded at the same time, so I am currently unable to use the gui to sync onedrive. I am uninstalling the onedrive-gui and using the AppImage as a temporary workaround.

        ReillyBrogan I would have to check, definitely the core Qt5 and QT5-devel. I know its EOL but when working on Industrial to update everything to QT6 is doable but ATM its not ideal esp when Plasma 6 is not mature enough for 24/7 operation. When Plasma does mature however then updating to QT6 will be fine. There is however other apps that rely on Qt5 libraries so it would be good if they hung around for a while.

          Must have. I can't find any way to delete those bloated sessions, either. There's nothing obvious in the context menu, or the Files menu. Gonna look through the hidden files in my /home directory now.

              Fixed that. I deleted vivaldi-stable, and the Vivaldi .config folder in my /home directory, then re-installed the app,
              After a little configuration, and creation of new tab stacks, that list of sessions now looks like this.

              Vivaldi is now squeaky-clean, lightning fast, and there's no problem with hibernation.

                  WetGeek that has been plaguing you for a long while. good job getting your hibernate back.

                    banger Thank you. I have no idea what's going on. I did some spelunking in the depths of Mozilla's bug list and that error seems to crop up from time to time. Anyway, I installed the flatpak and it works. Fine by me.

                    EDIT: That didn't age well. FlatPak Firefox can't communicate with KeePassXC. I downloaded Firefox 130.0.1 from mozilla.org and installed in ~/ and the mail button works. It seems it's not a Firefox bug after all. I dunno.

                        i trying new pc to install solus kde but iso image bootable drive not recognise image message.other distros boot & install properly. any problem in iso file?

When running eopkg check, the LTS kernel shows as broken. This is a false positive, and can be disregarded.

                        Should I get it for linux-current as well? Is it fixed for current and I shouldn't see it?

                          this is very well known known; it's happened to me and it's (sadly) normal since the flatpak is sandboxed. that doesn't mean it won't work in another browser. for a while. maybe it worked in firefox before but when it quits working it quits working. there's a thread where me and @axios spent days trying to figure out the flatpak to solus to keepass extension relationship. Could never get it to work was the conclusion because it wasn't a native package.

                          Anyway I solved this by liberating myself from the browser extension that I didn't trust anyway (it had too much control) and cutting and pasting [crtl b / ctrl c] straight from the keepassxc app itself. may seem primitive but its second nature now. edit: second nature for flatpak browsers.
                          2 cents

                            AlphaElwedritsch Sadly, no - probably. There are some possible workarounds (editing some files), but none of them seem to work reliably in all cases. Anyway, I have downloaded Firefox 130.0.1 from mozilla.org into my home directory and it works. I suspect it's a weird side effect from some compile flag that's the culprit.

                            BTW: According to the estimation on https://fossies.org/linux/www/firefox-130.0.1.source.tar.xz/cloc_cs.html Firefox has over 33 million lines of code. That's more than the Linux kernel with less than 28 million. Even the open-source AMD GPU Linux Kernel graphics driver now has almost 5.8 million lines of code. Nobody has a clue anymore why things even work in software. We've made a mess of things.

                              pillmuncher It's not actually a Mozilla bug. We have to set some environmental variables in the Firefox launch script in order to make Firefox work correctly on Solus. The problem is that these environmental variables are also used by Thunderbird since they share much of the same code and if they're set to the values FF needs it breaks Thunderbird. When you click on a link in FF that opens something registered to be handled by TB (like mail links or calendar invites) it opens TB as a child process of FF and TB inherits the environmental variables from FF (which breaks it).

                              Ideally there would be TB and FF specific versions of these variables so that they wouldn't conflict anymore, but as far as I can tell that isn't implemented yet upstream. I'll look into creating a patch to add them.

                                update and usr merge went fine 👍️
