One down, one to go

altivoThe 30 gallon tank (with fish in) is clearing up nicely, just a little cloudy left. Ammonia level is up, though, so water change tomorrow early. The 20 gallon tank (no fish) still looks like milk, has only a trace of ammonia. Both pH high (7.6+) so added 5 ml of white vinegar per 10 gal water to each. Will check pH again tomorrow.
Tomorrow's agenda includes getting a power head and sponge or canister to add aeration to the 20 gal tank and push this cycle along.
Wasted a chunk of time this evening on tun/tap and bridges in Linux. There's tons of "how to do it" documentation, all of which fails to get everything right or explain the address assignments clearly. I did finally get it to work, though, so now a SIMH virtual guest machine can share the outside network interface with the Linux host, and both can still see each other and communicate.
X tries to work too, but I begin to suspect that Ubuntu has altered the Xserver in ways that make it unstable when more than one instance is running on the same machine. It doesn't crash, but keeps getting confused about which display has the keyboard and mouse active. This is likely a result of typical Ubuntu arrogance in assuming that no one needs to use these features so it doesn't matter if they get broken. Grr.
Debian itself seems not to suffer from these flaws.

It's probably simply not the kind of use case that Ubuntu is intended for. Running two X servers on the same machine is probably quite uncommon for the average non-technical desktop user who only wants to surf the web or read emails or write documents.
Just curious, why are you using Ubuntu in the first place?

As for why Ubuntu, well, I ask myself that occasionally. The main reason I switched a year ago, though, is the fact that Canonical does a pretty good job of keeping all the security patches and updates to popular software like Firefox or Adobe up to date and available. You get automatic notices of updates and can install them easily at your leisure, much the way it works with Windows. Canonical resolves conflicts and keeps the important stuff working for the user, where with other distributions I've had to go download my updates from various locations and sometimes even compile and debug them myself. I'd rather save the compiling and debugging effort for my own projects.
It's been an experiment with mixed results, and quite frankly, Canonical and Ubuntu do seem to be heading off the mainline now and I'll likely be switching back to Debian or something before much longer.
Running two X servers on the same machine is a standard operation that is expected to work. I agree, not many people do it regularly, but in the standard X implementation it is supported and legal. Canonical has made heavy modifications to gdm for no reason I can understand and probably because they themselves don't understand how it is expected to function. Those modifications get in the way of many standard X operations, and hunting down the ways to get past them has consumed too much of my time lately. In the last few months they've announced their intention to abandon gnome, KDE, and XFCE in favor of their own desktop paradigm, Unity. That fits your assumption that Ubuntu is for the unimaginative. I don't care for Unity at all, and switched it off on my netbook immediately after installing Maverick Meerkat (which had it as the default.) They also seem to be heading for Chrome as the default browser instead of Firefox, and I'm not interested in that.
