  • Separate X Sessions Do Not Work in Kubuntu 8.10

    I sent this in as a bug to Launchpad, where it became Bug 337777 (not octal, BTW) and was marked as a duplicate of Bug 192413. It’s been triaged as Low priority, so I think my days of using KDE are, alas, pretty much finished.

    Herewith, the straight dope, just in case you were thinking of doing the same thing.

    ————-

    In Kubuntu 7.04, I managed to manually configure separate X sessions using two nVidia video cards driving two monitors. The setup involves a 1600×1200 landscape monitor on the left and a 1680×1050 monitor rotated 90 degrees CCW on the right.

    In Kubuntu 7.10, this worked reasonably well.

    In Kubuntu 8.04 / KDE3, this works poorly. X seems to regard the right-hand monitor as being 1600 (1680?) x 1200, so all windows maximize incorrectly and “centered” dialogs appear off-center to the upper right on that screen. I installed an nVidia-based dual-head card in the hopes that it would work better, but that made no difference. The setup is usable (I’m using it now), but not desirable.

    The automatic configuration tools fall flat on their face: any attempt to use the standard KDE display tools pooches xorg.conf. I must carefully tweak xorg.conf to keep this setup working in the face of any X changes.

    In Kubuntu 8.10 / KDE4.2, this configuration flat-out doesn’t work. After considerable manual fiddling, I got a blank X session on the right with the default X cursor and a black background; the mouse pointer moves from one screen to the other, but that’s as good as it gets. The left screen works more-or-less normally, but with some weirdnesses. Diligent searching reveals this is the common endpoint for all folks attempting this configuration: KDE4 simply doesn’t support separate X sessions.

    I do not want Twinview / Xinerama (which also work poorly for this configuration), because I typically edit a single document in portrait mode on the right screen while flipping between circuit simulators / web browsers / PDF documents / PCB layout editors on the left screen. A single X session using two screens does not support that functionality; particularly in KDE4 which seems to lack the advanced window positioning controls of KDE3.

    Because KDE4 is mandatory with 8.10, I can’t downgrade to KDE3, which might work.

    Although KDE4 seems to be the future, it would be immensely more usable if it didn’t introduce serious regressions from previous functionality. I will gladly trade off all the Plasmoid foo-foos and Compiz go-fast-stripes to get stable X capabilities that work the same way as 7.04.

    The to-be-expected alpha-version issues in 9.04 prevent me from even installing it at this point, so I cannot say whether it’s an improvement or not. From what I read in the forums, things do not look promising.

    Perhaps this is less of a “bug report” and more of a plea for stability: please, first make KDE4 *work*, then make it pretty!

    ————-

    For what it’s worth, I installed Xubuntu in that partition, added one line (Option “Rotate” “CCW”) to xorg.conf, and It Just Worked. XFCE is a bit lacking in creature comforts, but it works in this configuration. I think I can get used to that.

  • Verizon FiOS: What’s the Real Price?

    So FiOS has finally arrived here in the hinterlands and the latest teaser deal is $70/month for 10/2 Internet and anywhere-in-the-US VOIP. The ad mailers always tout the blazing speed (although that’s not what they offer in the teaser) and voice clarity.

    But there’s an asterisk: the prices are always “plus taxes and fees”.

    So I called the FiOS order line (877-896-2263) with two simple questions:

    • What, exactly, are those taxes and fees?
    • What, exactly, will they add up to each month?

    After five minutes of telling the nice man everything they already know about me and giving him permission to read their own records of our account, I managed to push him off his script long enough to get a word in edgewise.

    He tells me that the taxes and fees depend on my exact location and the services I sign up for. I point out that we’ve just established my address and he should know what services he’s offering, soooo what’s the price?

    We go around and around:

    • He says the only way to find out is to sign up and get my first bill
    • I refuse to buy something without knowing the price

    Eventually he offers to transfer me to billing, where he says (and I have no reason to doubt) that they’ll certainly tell me the same thing. Sounds like a good idea to me, if only to get to the next screen. He’s obviously miffed that I’m not following my lines in his script and just buying FiOS like a good sheeple.

    I hear the usual beeps & boops, a snippet of their on-hold blather, and dead silence. Ten seconds later, the call disconnects and I get the usual “If you’d like to make a call, please hang up and dial again” message.

    They don’t care. They don’t have to. They’re the phone company.

    Right now we’re getting 13/2 Internet from Cablevision (aka Optimum Online) for $50 and a Verizon landline for $25.

    Let’s see: slower Internet and marginally cheaper phone service, plus the asterisk. Not a compelling value proposition in our situation. But, then, we’re cheapskates.

    Incidentally, the “taxes and fees” make up $10.61 of this month’s $25.09 phone bill. I have good reason to believe that if we buy two services from Verizon, the fees will add up to $20 or so. But there’s no way to find out without buying them first, of course.

    I’m seriously thinking of killing the damn landline and struggling along with VOIP and our $5/month cellphone.

    Update: Today’s mail brings an even better teaser with a different phone number: 877-896-5322. It’s still $70/month for a one-year “agreement”, but now with free activation and a $100 cash card and they guarantee the rate for two years. The kickbacks push it just under $60/month for the first year. Still has that asterisk, though. Not to mention that the offers just keep getting better and better … I’m sure the early adopters are astonished at Verizon’s sliding incentive scale.

    Update 2: If you ignore the flyer and sign up for FiOS via the Verizon website, you get an additional $5/month off and you don’t have to deal with Verizon customer service. That brings it down to $55 plus the dreaded asterisk… I wonder what next month’s mail will bring?

    Update 3: Another flyer and the offer is still $70/month, free activation, and $100 cash back. Somehow I think FiOS uptake around here isn’t living up to their expectations.

    This flotsam recently washed over the railing. I added the bold highlight:

    Treating the attached PDF with the same casual nonchalance I use with any lump of high-level radioactive waste, I opened it in The GIMP (to strip any interesting PDF malware) and found an ordinary printable PDF form.

    Surprisingly, it didn’t have any slots for charge card or bank account info, but, down at the bottom, there’s a dense block of fine print.

    I ran it through pdftotext to get the raw text and here’s the kick in the head, boldified for your reading convenience.

    I haven’t checked out the full T&C, as I doubt I’ll benefit from such a listing.

    This probably works best in large organizations, where one sucker responds to the spam and then the billing department responds automatically to incoming invoices. The two-month advance notice is a really nice touch, isn’t it?

    Why do people continue to fall for this crap? If it didn’t pay off, the spammers would dry up and blow away, so there must be a fresh crop of suckers every day.

    People, stop doing that!

  • Mobile Phone Contact List Portability, Lack Thereof

    I just finished re-typing my (admittedly limited) list of contacts, merging the lists from my ancient Virgin Mobile Nokia Shorty and my new-but-defunct Kyocera Marbl into the replacement Marbl.

    These things should be able to bag up their internal representation of my Contacts into some standard interchange format, place that file somewhere, download such a file, and poof be up and running.

    If Virgin wants me to keep buying phones, why do they make it such a pain to start up a new one? Come to think of it, I know why: they don’t make any money on the phones, so they must maximize the phone’s lifetime, while simultaneously touting new features to entice new customers.

    I’m still grumpy from driving too much, even after a mid-morning nap.

  • Technology Oopses

    Driving back from Cabin Fever, we passed the second-most-famous nuclear reactor site in the world.

    After the fly ash spill last month in Tennessee, I’m waiting for calls to immediately shut down all coal-fired plants.

    Maybe that’s like waiting for PETA to start picketing halal butcher shops. In Tehran.

    Driving makes me way grumpy.

  • Cell Phone Web Browsing

    Oh, that Kyocera Marbl from Virgin Mobile I mentioned here? One of its bullet item features is “web browsing“.

    The screen is roughly the size of a large postage stamp and displays text amounting to, in round numbers, five lines of three words each. Graphics are not an appropriate use of screen real estate.

    I have not signed up for a “data pack” to enable cheaper browsing.

    There’s nothing I can say about this that doesn’t sound snarky.

  • Dell GX270 Auto-On Power Setting

    I bought an off-lease Dell Optiplex GX270 from Dell Financial Services (via the highly useful techbargains.com) to update my mother’s PC.

    For the last month I’ve been twiddling it every now & again in preparation for my next visit, plus just letting it run to get some power-on hours under my supervision. You’ll find some of the info on that process earlier in the PC Tweakage category.

    So it’s been booting up automagically at 6:15 am every morning, which is easier for Mom, but every now & again it wakes up dead. This is why I’m doing a month or two of burn-in here!

    The diagnostic LEDs (the ABCD lights on the back panel) are GYGG, which isn’t listed in their hard-to-find LED reference. [Update: maybe now at Optiplex Diagnostic Indicators]

    Dell Optiplex GX270 Auto-On Boot Failure LEDs
    Dell Optiplex GX270 Auto-On Boot Failure LEDs

    I did the usual diagnostic stuff. All the Dell diagnostic tests work fine, replugging the memory doesn’t help, and so forth & so on. Running many passes of memtest86+ (from the invaluable System Rescue CD) shows no problems at all.

    Called up 800-891-8595, the DFS warranty service number (which is different from the usual Dell route), told my story, and got a call back (!) from the tech. I related the situation, mentioned that I’d set it for auto-on, and he said “Oh, they never got that BIOS code working, it’s never been released, and I’m surprised it works at all.”

    Riiiight…

    This is a biz machine, the sort acquired in semitrailer loads by big companies with actual IT departments, the ones that automagically wake up their flock of machines for overnight updates. Maybe they trigger auto-on through the LAN port (that’s another BIOS option) these days, but the BIOS wake-up alarm clock function has been available in pretty nearly every Dell I’ve ever owned… and works fine.

    This is not rocket science.

    Indeed, if anyone’s ever had the slightest problem with Dell’s auto-on, Google shows no sign of it. There’s nothing on the normally loquacious Dell forums. Nay, verily, the GX270 manual itself touts the “advanced feature” of having it turn on at a preset time and day.

    Anyhow, he says the LED code shows the problem has something to do with the memory or video chip not starting up in time. That information is in his “internal” debugging info, which is not available to mere customers. He’s unwilling to swap memory (I tried another stick to no avail), let alone the system board.

    Conclusion: his assignment is to make me Go Away without spending any money on warranty repairs.

    Seeing as how the GX270 was a whopping 100 bucks delivered, I can sympathize with his marching orders, even if I disagree with their outcome.

    So maybe Mom’s going to have to get used to turning the box on in the morning; it seems to work perfectly that way. A straightforward crontab entry turns it off in the evening… at least that part still works.

    I’ve bought other off-lease & Dell Outlet boxes; they’ve worked fine. This one is a bit more battered than usual, but it’s otherwise in fine shape. It’s even been re-capped; the larger electrolytic caps aren’t the dreaded Nichicon popcorn caps.

    Update: It seems to be booting OK with this burn-in regimen.
