To the developers of Ubuntu Linux: Please stop pushing updates that break our video drivers!

"XBMC needs hardware accelerated OpenGL rendering" error

In the past couple of years I’ve helped install Ubuntu Linux on four HTPC systems, three of which were Acer Aspire Revos (two are still in use), and the fourth an ASRock Vision 3D. On each of these we’ve had a recurring problem where Ubuntu pushes an update to Linux (which appears in the Update Manager along with other updates) and then you start having video problems, or problems with your HTPC software.  In the most extreme cases, Ubuntu appears to not boot at all – you simply get a black screen.  In reality it has booted and you can SSH into it from another machine (assuming you’ve had the knowledge and foresight to enable SSH access), but the graphic display manager isn’t working, so you either get a blank screen or just text.  In less extreme cases, it will still boot into the desktop but when you try to run your HTPC software (such as XBMC or Boxee), it won’t start.  Instead it may fail with a message similar to “XBMC needs hardware accelerated OpenGL rendering. Install an appropriate graphics driver”.

The problem always seems to be the same and it’s the one I wrote about in the article, If your Linux-based PC with NVIDIA graphics started booting to a black screen or text only, here is the fix — maybe!  I suggest you read that article BEFORE you have the problem!  It’s just getting REALLY annoying to encounter this issue every few weeks, and while it’s happened so often that I now know the drill to fix it, I can imagine that it probably sends new Ubuntu users into full panic mode (I know it really freaked me out the first time I encountered it).

This is not an uncommon problem either. Putting the phrase “XBMC needs hardware accelerated OpenGL rendering” (including the quotes) into Google brings up “About 2,500 results” as I write this. To me that indicates that about 2,500 people, give or take a few, have had this issue hand have been frustrated enough to have posted something somewhere on the Web about it. There are doubtless thousands of others who searched on the phrase and found enough information to fix the problem. And it’s NOT what I’d call an easy fix for someone unfamiliar with using the Linux command line or working outside the Ubuntu GUI.

Every so often I read one of those articles about how the new versions of Ubuntu are so easy to use that even your grandmother could use it. Bzzzzzt! Sorry, that’s wrong, not as long as shit like this happens. Unless you have a very uncommon grandmother, she is probably not going to be able to figure out how to download and reinstall a video driver.

The solution is simple: If you can’t push out Linux upgrades that don’t break our video drivers, then stop pushing out Linux upgrades! Or else, figure out or to make it download and upgrade the video driver at the same time. Or at the very least, pop up some kind of warning message if someone is about to do any update that will likely break things, and give them the option to permanently exclude such updates.

And I don’t want to hear any crap out of anybody about how it’s stupid to install updates if you don’t know what they do. Ubuntu pushes out these updates via their Update Manager software, which pops up and basically nags the user to install the updates. You can close and ignore it, of course, but every so often it will keep nagging you to install the updates.  Users coming from another platform (particularly Mac users) will probably assume it’s okay to install all offered updates.  I just question the wisdom of pushing out Linux kernel updates this way — those are in a totally different category than, say, an upgrade to a new version of Firefox, and yet the user is not in any way warned that a kernel update is a pretty serious upgrade that could cause breakage.

P.S.  Please do NOT get the idea that I am any kind of expert in this stuff.  If you leave a comment asking for help in fixing your system, it’s probably going to sit there like a big old smelly dog turd on the lawn, with no replies at all, unless I or a reader just happens to know the answer, which is rather unlikely!  There are much more appropriate forums for requesting help — please use one of those.

DSLreports.com: Wisconsin Data Shows AT&T’s ‘Franchise Reform’ Was A Joke – Now consumers get higher prices AND no consumer protection laws…

A long time ago, this blog had a somewhat different direction than it does today.  Part of what I tried to do was expose the abusive practices of the large phone companies, and (among other things) try to stop them from basically writing the communications laws that were supposed to regulate them. One of the reasons I shifted directions was because, basically, we customers lost, and I don’t enjoy beating a dead horse.  And only now, it seems, is the reality of what happened finally dawning on state officials, as indicated in Karl Bode’s article on the BroadbandReports.com/DSLreports.com site:

Wisconsin Data Shows AT&T’s ‘Franchise Reform’ Was A Joke — Now consumers get higher prices AND no consumer protection laws…

We’ve discussed how a significant number of states passed new state level video franchise laws at the behest of phone company lobbyists, but didn’t really realize what they were signing up for. Bills that consumers were told would result in lower TV prices by making it easier for phone companies to jump into the TV business, in many cases were little more than phone company wish lists — aimed at legalizing the cherry picking of next-gen broadband deployment, eliminating local authority (even eminent domain rights) and in some cases eliminating tough consumer protection laws.

The one thing the laws were supposed to do — lower TV prices — never actually happened.

One of the worst of these bills approved by duped lawmakers was in Wisconsin, where AT&T both wrote and lobbied for a bill that essentially gutted all consumer protections in the state under the auspices of cheaper TV. State residents used to have the right to prompt repairs, saw ensured refunds for service outages, mandated notice of rate increases or service deletions, and carriers had to provide a written notice of disconnection. Not any more. Now a new Wisconsin state audit shows that basic TV prices continue to skyrocket:
…..

One Wisconsin legislator (Representative Gary Hebl of Sun Prairie) has introduced a new bill that, he says, “puts people first, not corporations.” Well, if that’s really true, it’s about damn time (pardon my expressiveness, but it is!). All laws ought to do that.  Our Constitution ought to do that. Of course, it remains to be seen whether Rep. Hebl’s bill ever gets passed into law.

Here in Michigan, our legislators have been sold a similar bill of goods. About the only thing that did not happen here is that we did not completely do away with quality-of-service requirements.  But our wonderful Michigan legislators did pretty much eliminate all other consumer protections. They turned the Michigan Public Service Commission from an agency that was able to help consumers solve most any communications-related issue, to an agency that’s pretty toothless with regard to anything telecommunications-related. Unless you are subscribing to one specific landline service that virtually no one has or wants (PBLES), you now have very little protection against abusive practices by the phone company, unless you want to take them to court or file a complaint with the state Attorney General’s office (actually, I think aggrieved customers ought to complain to their state legislators – they made this mess, let them clean it up!).

(Just so as not to mislead anyone, I will say that complaints to the MPSC sometimes do still bring results, but only because the MPSC knows how to reach the top executives at some of the phone companies.  The MPSC usually can’t force the phone companies to help you anymore, but sometimes they can present your case to a high enough official that you’ll still get the desired results.  And, if you actually do have a quality of service issue – your phone doesn’t work and they tell you they can’t fix it for another month – then the MPSC does still have some authority in that type of situation).

One other point:  For nearly two decades, the Michigan Telecommunications Act had a “sunset” provision, such that it automatically came up for a rewrite every four or five years.  The phone companies always saw this as a chance to re-craft the law to be even more to their liking, while consumer groups and legislators that felt they’d been “hoodwinked” the last time around saw it as a chance to restore some previously lost customer protections.  But a funny thing happened on the way to the latest rewrite – a couple of years ago, the Michigan legislature quietly killed the sunset provision, making the current Michigan Telecommunications Act the one we’ll probably be stuck with for decades to come.  This indicates to me that the phone companies got what they really wanted last time around, and had no intention of letting the applecart be upset by disgruntled consumers or legislators in 2009.

Of course, any one of our legislators could, on their own initiative, introduce legislation that would attempt to undo the damage that was done in the last Michigan Telecommunications Act rewrite.  But unless they receive enough complaints from affected citizens, I doubt they’ll want to poke that particular beehive (the bees being the big telco lobbyists and lawyers, which would probably come into the state in full fury if there were ever any serious attempt at reform).

One way consumers could make an effective statement is to “vote with their feet”, and refuse to purchase any service from a large company that abuses their customers (especially when there are any other viable options available). But most customers don’t have that kind of willpower – all the “evil corporation” has to do is dangle a shiny enough carrot off the stick (in the form of a great “limited time promotional offer”) and we, like a bunch of stupid jackasses, subscribe to their services.

Like I said, I’m not into beating dead horses – once they’ve been dead long enough, they really start to stink — kind of like our Michigan legislature (and, presumably, their brethren in Wisconsin) when the big corporate interests come around.
