GNU/Linux: PowerBook unleashed. Well, sort of..

Monday, April 25th, 2005

Bored? You know your system inside out? Everything is just working? No more hacking required if not screwing up the system on purpose yourself? Even the unstable and experimental branches of your distro don’t bare challenges anymore? Here’s the solution: Switch $ARCH(tm)!

OK, it wasn’t that bad. This is my first entry using BloGTK (No, no Fink involved) under Ubuntu / Gnome 2.10 (Spare it, for this one I’ve been accused of heresy already). After some time figuring out what is needed to run Linux on a PowerBook properly, it’s up and running pretty well. Of course, there’s room for improvement but my basic needs are covered. Here’s the progress so far:

  • Custom Kernel for you just can’t run a stock-kernel, can you? Current kernels don’t support sound on new PowerBooks. Benjamin posted a patch to the debian-powerpc mailing list which is included in 2.6.12-rc3 which is what is running here currently. Unfortunately, CPUfreq refused to build. Colin released two patches fixing that issue. On a side note: if you plan to do without an initial ramdisk, make sure that besides the filesystem drivers of your root partition the IDE drivers are compiled in.. that one took me a while.
  • With the patches mentioned above, CPU frequency scaling works flawlessly. Testing on the battery life to come.
  • Trackpad. Current PowerBooks seem to use USB for the keyboard and trackpad so the ADB drivers won’t work anymore. The keyboard works fine, for the Trackpad, Johannes wrote a driver, providing kernel-module and an userspace driver. It’s a little bit bitchy from time to time and has some limitations (no clicking by tapping the pad or scrolling), but works fine besides that. There’s also a working USB mouse here, just in case.
  • USB and Firewire storage devices work out-of-the-box. The gnome volume manager seems to have problems handling multiple devices at once, though.
  • My D-Link DWL-122 WiFi USB stick works fine using the latest linux-wlan-ng drivers, hotpluggable and WEP enabled. Screw Broadcom.
  • Wired connectivity required? Internal ethernet works out-of-the-box.
  • The special keys are also working mostly, that is volume, mute and eject using pbbuttons. Brightness control does not but I haven’t looked into this, yet.
  • For nvidia won’t release drivers for ppc, I’m stuck with x.org’s nv driver. No 3D acceleration and therefore no advanced composite eyecandy, at least not with decent speed. Connecting an external monitor might also be a no-go.

Putting some problems with uber-proprietary stuff aside, the PowerBook turns out to be a formidable platform to run GNU/Linux on if you have some basic knowledge. Well, enough for now, more to come..

Usual Debian and OSS weirdness..

Wednesday, April 20th, 2005

Reading this week’s DWN was fun and for I’m lazy, I just quote the fun part:

“GPL Programs belong in non-free? Adrian Bunk noted that all programs licensed under the GNU GPL have to go into non-free, since the GPL license itself must not be modified.”

Can Adrian be serious? How many beer would one have to drink? I have to admit, I had to read the post a couple of times before it clicked. Actually, it didn’t really click. No enlightenment.

(Before I go any further, please note that Adrian didn’t request anything, he just pointed at a possible problem with the DFSG. I’m well aware of that.)

While this might be a interesting topic to hang ones mind on (in certain conditions caused by consuming various substances), at least from a philosophical point of view, after performing the most basic reality check the bleak truth brakes free (hopefully!): This is ridiculous, big time, IMO. I mean I know know a bunch of hardline FOSS fellows who wouldn’t have that much applications left for they simply refuse to use non-free.

Can more freedom actually mean that you pull the ropes around your wrists a little tighter yourself?

If you ask me, such things have nothing to do with Open Source, Free Software Guidelines, “Free as in free speech” or anything else that claims to be about freedom in any other way. This is fundamentalism.

This thread on debianforum.de (german) brings up related topics. It started with someone pointing to Torvalds’ statement that OSS is alright as long as it’s fun. And it went from there.. GNU, Stallman, Jesus, scientists in fascist germany and so on. While it’s an interesting read and there are valid points on both sides, I’m a little worried about the course such non-existential discussions, that started with babbling about the fun of a notorious nonpolitical being, seem to take sometimes.

Missing (K)IO-Slaves

Monday, April 18th, 2005

Like I’ve written here, Finder’s lack of FTP-uploading capability bothers me. KDE’s FTP-KIO-Slave enables me to do the following:

  • Browse to the appropriate directory on my FTP-server using Konqueror.
  • Open the desired file with Kate, KDE’s Advanced Text Editor.
  • Edit the file and save it back to the FTP-server. Directly. No local copy and manual FTP-uploading required.

This is a very handy feature and I’m somewhat used to it. Is there any feasible way of doing so using OS X? Will Tiger’s Finder support such functionality or at least FTP-uploading? Guess I’ll have to wait and see. Anyhow, I’m open to suggestions and no, I don’t have SSH access to my FTP-site.

System flooding

Friday, April 8th, 2005

I just wondered why there’s no space left on /, here’s why:

$ ls -l /var/log/kern.log
-rw-r—– 1 root adm 1013111466 Apr 8 17:04 kern.log

seems like my fscking wlan-stick just can’t get it straight. It filled the log with 1GB of the following:

Apr 8 09:42:45 localhost kernel: hfa384x_usbin_callback: wlan0 rx pipe stalled: requesting reset
Apr 8 09:42:45 localhost kernel: hfa384x_usbin_ctlx: Could not match IN URB(0×8003,-75) to CTLX – ignored
Apr 8 09:42:45 localhost kernel: wlan0 rx pipe reset complete.

Flaming debian-kde

Thursday, April 7th, 2005

For an exampe how people never get tired of flamimg and trolling on the same topics over and over again, check this thread on the debian-kde mailing list.

It all started with the somewhat innocent question if KDE 3.4 will hit SID anytime soon. The unavoidable followed soon enough: “And where’s x.org?” “Can sarge be considered vaporware?” “Why can’t Debian if Ubuntu can?” “So get lost and use ubuntu” “Who needs x.org anyway?” “Some ppl have the latest on-board graphics only supported by x.org!” “Hell, Ubuntu is _based_ on Debian, Debian-devs are doing the majority of work here!” “Debian-devs are arrogant pseudo-elite anyway.” “Libranet! and I paid for it!” “Then what are you doing on this list anyway?” “Btw, how do debian-devs get their money?”

I guess you get the picture. Even though most points are valid from the appropriate perspective, this all has been argued and reasoned before. Anyhow, it’s pretty hard not to reply to this thread, it looks so much fun.. then again, I really don’t consider myself addressed by any of the statements and generally I refuse feeding trolls.
