Nepomuk

I think I finally fixed it.

This stupid “OMG Nepomuk is not running!” error has been dogging me every time I launch KMail, ever since Fedora upgraded KDE. I followed all the directions on fixing Akonadi, and nothing worked. Finally, it turned out that there was a config file telling it to load the old-style “redland” database — which doesn’t exist in current versions of Nepomuk — instead of the new “virtuoso” database.

The file was in ~.kde/share/config/nepomukserverrc and the item in question is “Used Soprano Backend.” I changed it from “redland” to “virtuosobackend” as described here and now it actually starts Nepomuk, and KMail doesn’t complain when I start it!

Someone at KDE decided to massively overcomplicate things!

*grumble*

Dissonance

  • Contrast in the waiting room at the car dealer’s service department: A sad death scene in the movie on TV vs. polka-sounding video game music from a few chairs over. #
  • *sigh* I upgraded my Linux box to Fedora 12 in hopes that it would fix sound. Instead it broke suspend/resume – which I’d rather have on this system if I could only choose one. #

Wednesday Bits and Bytes

  • I finally uninstalled I Tweet. Twidroid Pro does enough that I don’t need two Twitter clients on my phone anymore. #
  • Grr. Since the last patch day, my USB keyboard randomly stops working 2–3 times/day. System Restore would be nice…if it actually worked. #
  • I’m trying to remember when the BOFH attitude prevalent on antispam mailing lists didn’t bother me. #
  • It’s weird how suddenly reporting spam turns into a bad thing because someone (else) might make money with that knowledge. #

Hear me!

Vertical Horizon: Burning the Days.A few minutes ago I was trying to fix sound on my Linux box. Nothing would play, until Katie heard it beep to notify me of a new Twitter message. I closed Twhirl and suddenly my music player worked. The song lined up? Vertical Horizon’s “All is Said and Done.” The first line of the song? “I need you to hear me.” That gave us both a good laugh.

I thought a major point of PulseAudio was to let applications share the sound card cleanly. *grumble* Sound worked fine before Fedora switched. I can’t even blame it on a bleeding-edge distribution, since from what I hear, Ubuntu has similar problems.

At least now I know (sort of) why it stopped again after applying the Complete guide to fix PulseAudio and video/audio VLC Media Player issues.

Impressed by Smooth Fedora 11 Upgrade

Fedora LogoA few days ago, my Linux desktop at work popped up a message saying that Fedora 11 was available, and asking whether I wanted to upgrade automatically. Well, I didn’t have time to deal with it then, and in the past when I’ve upgraded Fedora (either from a CD or from a downloaded image), it’s been a big production, what with running the installer, rebooting, installing updates, updating third-party repositories, and finally rebooting again after all the updates are installed.

So I put it off for a few days.

Today I decided to try it.

The automatic upgrade program is called preupgrade, presumably because it downloads everything you need in order to prepare for the upgrade. It downloads everything while your system is up and running, then sets it up so that when you reboot, it will launch the installer. It installs everything, makes the changes, then reboots into the newly upgraded system.

And then it’s done.

It’s network aware, and works through yum, so it will actually take into account both third-party repositories and anything that’s been updated since the new release. It actually went out to livna.org RPM Fusion and picked up the appropriate NVIDIA display drivers.

Download while you work. Reboot. Wait. Done.

The only snafu I ran into was that it removed my copy of the Flash plugin, but I think I was using the experimental 64-bit one anyway, so it’s not terribly surprising.

I get the impression that Ubuntu has had a similarly smooth upgrade process for a while. And after my experiences moving from Fedora 9 to Fedora 10, I was seriously considering jumping ship. (Hazards of living on the bleeding edge.) But it looks like I won’t have to.

Now I just have to find time to play around and see what’s new!

Update: I’ve run into one snafu: xkb error popups every time I wake the computer from suspend. Resetting the keyboard worked.
