Siju George noticed that his mouse would stop working in X, perhaps every hour. Restarting X would fix it, but he didn’t have a clear cause. Antonio Huete Jimenez suggested turning the sysctl ‘debug.psm.loglevel’ to 9 to at least see what messages cropped up, and that seemed to fix it. I don’t think it’s a good long-term solution, but it’s worth mentioning in case this odd bug bites someone else.
Naoya Sugioka had trouble booting DragonFly on his Dell M4400. He updated ACPICA with this patch, and was able to boot. I link to it in case someone else with a recent Dell model (or perhaps just a laptop with the same chipset?) has the same issues.
A number of people have encountered this: while installing some larger pkgsrc package, the process stops on a strange DocBook error. Alex Hornung has a fix: symlink /usr/pkg/etc/xml/catalog to /usr/pkg/share/xml/catalog.
Alex Hornung is having trouble getting his power consumption as low as it could be on his DragonFly laptop. A side effect of this problem is that when he posts about it, he also manages to enumerate all the various ways you can reduce power consumption and heat usage on a laptop. (Follow the thread for more.)
If your system has trouble when APIC_IO is enabled, and you’re tracking DragonFly 2.9, you may have trouble on your next build. The fix is putting this in your loader.conf:
hw.apic_io_enable=0
I know this has already been covered, to some extent, but one can never be too clear with solutions.
YONETANI Tomokazu wrote out a nice explanation of acpi(4) and the myriad ACPI subsystems which can be enabled or disabled at boot time. If you do have booting problems, it’s usually ACPI, and it’s usually only one small part. Finding that small part is easier with this list.
Something that always got with with Linux binary support was that I couldn’t get the Linux /proc filesystem to automatically mount on boot. I’d end up doing it by hand later, right after I tried to start a Linux binary and had all sorts of issues. Pierre Abbat had this same problem, and Sascha Wildner has the answer: “linux_load=yes” in /boot/loader.conf.
When compiling software on DragonFly but outside of pkgsrc, and you have trouble with configure, remember you can always manually pull down new versions. You’re welcome, future me.
I’m linking to this commit message from Matthias Schmidt simply because it has the correct invocation for installing a vkernel, and I know this will come in handy, someday.
There’s a whole lot of options for bmake, used in pkgsrc, and they aren’t immediately obvious. I’ve linked to a reference before, but it’s no longer at that location. However, I found a new link!
Link dumps just so I can get caught up.
- Michael Lucas was interviewed about his new Network Flow Analysis (previously reviewed) book, in two parts. Also, he’s speaking at NYCBSDCon, this November 12th-14th.
- Dru Lavigne gave a talk on “Getting Started in an Open Source Community“. (via) In other video news, MeetBSD 2010 videos are available now.
- Random Google searches turned up a DragonFly installation video on Via hardware.
- Back to convention items: Kirk Russell has a short BSDCan recap. (via)
- Also, cluster ssh.
- Stathis Kamperis updated DragonFly’s One True Awk. (Huh. Brian Kernighan’s not at Bell Labs anymore.)
Using ‘serno’, meaning specifying disks by serial number rather than path, is a good idea. If you have a machine that started out as an older DragonFly installation, it may be a good idea to use this feature.
I apologize; I’ve been missing. Here’s some misc links while I get back in gear:
- A very good reason to be interested in Hammer over ZFS: nobody will threaten lawsuits over Hammer.
- 10 tricks for admins. I’m posting it cause I can never remember that thing with tunneling ssh out. (via)
- This Gaming Life, as a free download. An excellent book that is in physical form on my shelf right now. Yes, unrelated.
Sometimes, packages are renamed in pkgsrc, usually because of a version change. If that happens, it can be hard to find the replacement. You can manually add them, or there’s a trick to make the build ‘jump’ to the new name.
