I finally got around to the 15.1>15.2 upgrade the other day using the iso image on dvd, and here's a few notes. I'd like to hear what people think. I initially tried to update all repositories before the upgrade, but I must have messed up the pacman url, because it was not found and I had conflicts. I tried to use the back button to fix it, but couldn't find my back to the right spot, and decided to be conservative and start again with just the dvd. I ended up with conflicts anyway and resolved them one by one. The result was about 400 packages deleted. A lot of them were development packages and debuginfo and whatnot. I haven't looked further yet. After the upgrade I used Yast to switch to pacman, and it did pull some packages back in. I also used Yast for a serious online update. BTW, I noticed the main repository does not carry some chess packages such as xboard; they are only available from pacman. I then noticed about 600 packages still had an "x-lp151.x" sort of moniker-- zypper up took care of that. KDE's notification system isn't working due to a problem with xfce as described here: https://forums.opensuse.org/showthread.php/543232-Lost-notifications . I'm not entirely happy with the proposed solutions. I seem to recall KDE notification problems before, perhaps with 15.0, or maybe 42.0, where my system would fall back to xfce notifications until the KDE problems were fixed. That seemed like a nice behavior, all in all. ksysguard has gone from maybe 6-8% of one CPU to 30-40%. I've always tended to leave that running on one desktop, but 30-40% is unacceptable. It also apparently replaced my file read/write columns with Download/Upload. I have a CPU temp monitor in one of the panels that is not working. Any attempt to open its configuration dialog crashes plasmashell. Then there's akonadi. Akonadi_imap_resource, akonadiserver, and mysqld hog CPU continually on admittedly very large gmail folders until such time as akonadiserver "closes unexpectedly". I've also suddenly got 1131-300-200-100-300 emails in a drafts folder as reported variously by kontact and xfce. None of them are visible. Akonadi server somehow restarts itself. Hey, I can't watch Netflix while akonadi is running! At times past, I've bumped akonadi's priority down a notch. I haven't mentioned bluetooth which has been an ongoing problem for a long time. I've successfully nursed it in the past with restarts and whatnot, but I don't want to get into that at the moment. I used to use serial over bluetooth a lot, as well as tethering to my phone, but for the moment, it's a bit beyond me. So, comments? I can follow up on my downtime, keeping in mind that it will take time away from watching Netflix! ;-)
