kde-4.0.1 co-existence

for any who are interested,
Totally unofficial.
the SlackBuilds for kde-4.0.1 on Slackware-12.0 (and -current) are pretty well stabilized.
you can check it out with svn from http://batts.mine.nu/pub/src/SlackBuilds/kde4/
and its up to you to download the kde and deps source 😉
if it breaks, let me know, vbatts(AT)batts(DOT)mine(DOT)nu

thoughts[1]

motion moving,
everything is streaming, flowing
it itching to find its natural pattern.
the rhythym that life intended it to take.
refuge to the mountains, they know.
they’ve been there,

its the same on the inside that its is on the outside,
just the noise in between the two,
will distract you enough to believe that that is all there is
noise

Activity in Birmingham

last in Birmingham, AL, was the TechMixer Expo, downtown in the McWane Science Center.

with 700+ Pre-registered attendees, and appearantly many more that just showed up, my suscipions are that the show had well over 1000+ attendees.
we were there with the Bham-LUG booth, for linux and FOSS. i had my laptop on display. i enabled the xgl / beryl grapics for added eye candy. other guys from the group brought their personal OLPC XO laptop, we had probably 5 on display at any given time. we had 50+ live cd’s available, and only 3 left at the end of the night.

Good Times.

averatec 3250, slackware-12.0 to slackware-current

slightly easy and brutal at the same time. the steps to actually perform the upgrade were simple, and only like 5 steps.
major changes were a moving from kernel 2.6.21.5 -> 2.6.23.12 and to Xorg 7.3.
this is where the laptop appearantly had run ins. the Averatec 3250 is a VIA frameworked system down to the Video card, and it has a Ralink rt2500 wireless card.
the rt2500 is compiled seperately against the 2.6.23.12 kernel, i did so after i was booted into the the new systems configuration. if i am running on init 3 with no X, i can be on the internet just fine. OR if i startx and do not bring up the ra0 interface, everything works just fine. BUT if have both at the same time, the entire system fatally hangs after about 3 seconds after loads to where you see a mouse cursor, total system, not pingable, nothing.
after trying many variations of xorg.conf, or recompiling the rt2500 drivers, nothing seemed to work. but i did find that the ‘vesa’ video driver no longer works with this system, on Xorg 7.3.
eventually after trying to startx, and kill it as soon as i saw the mouse cursor, to catch it before it hangs, i found that syslogd dumped a message to stdout about the kernel disabling IRQ #11.
so after looking through the syslog, it threw something about how nobody cares but the kernel is disabling IRQ #11, try rebooting with irqpoll flags.

i rebooted, adding irqpoll to the lilo prompt, and now i can be in X and bring up ra0. so silly.

then i added ‘append = “irqpoll” ‘ to the slack section of /etc/lilo.conf, and ran lilo.

thanks rworkman for brainstorming with me.

Fun new stuff

significantly helping to post entries here more often, or easier, i’ve stumbled upon an app called blokkal, and is super. while it is entirely simple, it does everything for posting, reviewing, retreiving, modifying and/or deleting entries, that you would need for a blogging client to do. the only snag that i had, was solved relatively quickly by the designer Martin Muller. that is, if you use wordpress, you may need to check a box about a date time work around.
i overlooked this, and all of the posts were thirty years in the past, while interesting, it was frustrating me.


also, because work has been re-arranging, it has required an increasing level of windows usage. so i have been working with VirtualBox, its virtualization software with an open source edition. this has proven to be quite good for virtualzing, even though its not as stabile or point and click as VMWare is.
it running a WindowsXP guest on top of an openSuSE 10.3 host.
the two most difficult tasks with it have been, to configure a bridged interface, which is not terrible, just remember that suse has its’ default firewall configurations that interfere greatly. secondly, the physical host has an dual Intel Xeon processor, and the kernel is the bigsmp. Appearantly the are a few known issues with VirtualBox surrounding the tickless kernel and potentially smp functionality. I’ve added nohz=off to the boot line parameters and its seemed to alleviate the virtual guest from freezing on a regular basis, but we’re still watching the machine to test it more, before we use this guest as a “Production” box.
also, in that same thread, we are doing more with their Active Directory, for email and various services. so i have been able to experiment with various linux services that use or work against an LDAP/AD system, with significant progress. Much of which i will try to post, once i’ve ironned it out and sanitized it 😉


anyhow
later
