At first I thought this was related to Windows losing drives on wake. It started happening around the same time, it also involved waking up from sleep, and the CD/DVD drive was disappearing in Windows along with the vanishing hard drive.

But while moving the cables fixed that problem, it didn’t fix this one.

It was only mildly annoying, especially compared to regularly losing access to a large chunk of local storage, so I figured I’d come back to it later.

Other people are seeing this too and it’s a recent bug in the Linux kernel. At least with Fedora’s rapid kernel updates I probably won’t have to wait too long between when the patch lands and when it hits my desktop. It’s been years since I compiled my own kernel, and I don’t feel like starting that up again now!

Ah, memories! These days, setting up hardware on Linux is often easier than it is in Windows. Lots of drivers are built-in and auto-detected, and many are provided through a distribution channel that makes it almost as easy.

Wireless networking, however, is a bit of a throwback to the old days. Half the hardware doesn’t have Linux drivers, and half of the devices that do require you to hunt for the driver — based on the chipset, of course, not on the name or model number on the box — and compile it yourself. (At least these days, you can sometimes run a tool to adapt the Windows drivers if there’s no native Linux option.)

The steps I actually needed to take to set up wifi on my Fedora 13 desktop probably only amounted to about 10 minutes. Unfortunately it took a lot of false starts to get there. I had installed a Zonet ZEW1642 PCI card, which my initial research suggested would be supported by the built-in rt2860 drivers. As it turned out, it wasn’t that simple. Continue reading

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!
