Turning Caps_Lock into Control
Talking about keyboard problems: has anyone managed to implement the one and only keyboard hack, namely: *turning the Caps_Lock key into a Control key*. This is something I usually do easily using xmodmap on Intel machines, but any trick I tried failed on the tiBook. Is it at all possible? Does the hardware forbid it ? Or what ? Cheers, JF

I cannot play audio CDs on a tiBook
The CD drive itself works ok: I can mount a data CD (like mdk iso's)
and, launching tcd on an audio CD, I can see the audio tracks.
However, I cannot play the CD tracks. The log says:

at least 2 possibilities:
1) Because Apple has opted to remove the audio interface between the CDROM
and the sound chip,
Argh! Why, oh why, did they do that ?
you need to use xmms-cdread plugin to rip audio from the CD to play
music (ibook2 and beyond). It's in contribs.
I just tried the latest version I could find : xmms-cdread-0.11d-1 but
that does not work. Actually, the plug-in does not even see the
tracks (yes, I disabled supermount).
Now, if we see error messages such as
: ATAPI device hdc:
: Error: Illegal request -- (Sense key=0x05)
: Invalid command operation code -- (asc=0x20, ascq=0x00)
: The failed Play Audio MSF packet command was:
and also, in the same vein, such as
: ATAPI device hdc:
: Error: Illegal request -- (Sense key=0x05)
: Invalid command operation code -- (asc=0x20, ascq=0x00)
: The failed Pause/Resume packet command was:
: 4b 00 00 00 00 00 00 00 00 00 00 00
then does not that mean that we are facing a deeper problem ?
From what I understand, the KDE cd player will play OK with
supermount. I'm able to play audio CD's on my Powerbook, as well
as the TiBook I had on loan.
I tried gtcd, tcd and grip: they all failed at reading the tracks. I
do not have the kde stuff installed and I am a bit reluctant to
install it (my message is more a bug report than a help request, I do
not *really* need this CD stuff right now).
Now for something different:
The system is an mdk-8.0 which has been upgraded to be in sync with
cooker. In particular, rpm -qa | grep kern says:
: kernel-source-2.4.18-4mdk
: kernel-headers-2.4.17-24mdk
: kernel-2.4.18.4mdk-1-1mdk
Kernel headers do not need to be consistant with the kernel, but
they do need to be consistant with what was used to build
glibc. The kernel build is self contained, and does not use
kernel-headers. User space programs, for the most part, should be
using /usr/include/*. not /usr/src/linux/include/*.
Thanks for the tip. That calls for two questions:
1) Out of curiosity: how does one find which kernel header version
glibc is compiled against? (could not find it after a quick rpm
-qxxx )
2) I used to blame failure to compile the kernel on the above (non
existent) inconsistency. Shouldn't the kernel compile without
error if I am in sync with cooker *and* use the .config found by
default the kernel-source rpm ?

Re: [update] Problem reading audio CDs
More bug, buglets and non-bug reports about audio (on a tiBook). My system is an 8.0mdk, resynched with cooker. Just hoping to help fixing the default configs. Stew: please let me know if these buglet reports are useless (or just have too low a precedence on your todo list for me to bother you with them). 1) Problem reading audio tracks from a CD - I reported failure to read audio-tracks with xmms-cd, grip and tcd. - But, audio tracks are properly ripped (albeit rather slowly) when bypassing the middlemen by calling cdparanoia. -- The problem apparently belong to userland and not to sacry low-level kernel-space. 2) Problems with permissions and various configs. - After ripping a nice cdda.wav with cdparanoia, I cannot play it: o as user, /usr/bin/play reports: sox: Can't open output file '/dev/dsp': Permission denied o as root, /usr/bin/play reports: sox: Unable to set the sample size to 16 - After ogg-encoding cdda.wav, o as user, /usr/bin/ogg123 cdda.ogg reports: === Could not load default driver and no driver specified in config file. Exiting. o as user, /usr/bin/ogg123 -d oss cdda.ogg reports: Device: OSS audio driver output [deletia]Author: Aaron Holtzman [EMAIL PROTECTED] Playing: cdda.ogg Error: Cannot open device oss. Segmentation fault o as root, /usr/bin/ogg123 cdda.ogg just WORKS! JF
Re: [update] Problem reading audio CDs
ran time cdparanoia 1 4:39 track took 3:49.29elapsed on a PB Lombard, which wasn't doing much else except downloading an 8,2x86 ISO. I don't do enough CD ripping to know whether that's fast or slow. I should have been quantitative here. Ripping seemed slower than under OSX, but I do have (like you) quasi realtime ripping under linux. 2) Problems with permissions and various configs. - After ripping a nice cdda.wav with cdparanoia, I cannot play it: o as user, /usr/bin/play reports: sox: Can't open output file '/dev/dsp': Permission denied Unless you're in X, the permissions on /dev/dsp or (/dev/sound/dsp) exclude the audio group. I can't imagine this behavior is PPC specific. While X is running the ownership changes to the user running X. After I closed X, I was still the owner. I was not in X! So the permission problem is non existent. Sorry for the false alarm. I had no idea about this permission business (although it seems reasonable when you think about it). Thanks for the tip. o as user, /usr/bin/ogg123 -d oss cdda.ogg reports: Device: OSS audio driver output [deletia]Author: Aaron Holtzman [EMAIL PROTECTED] Playing: cdda.ogg Error: Cannot open device oss. Segmentation fault o as root, /usr/bin/ogg123 cdda.ogg just WORKS! Are you running devfs? I am here, which may account for some of the differences we're seeing. I am not running devfsd. Weird thing is I cannot launch it either: Running /etc/rc.d/init.d/devfsd start does not return an error, but does not print [ok] either. Checking devfs status says it is stopped (just after starting it). The daemon does not appear in the ps list. Looking at the /etc/rc.d/init.d/devfsd script, this apears to be due to the lack of /dev/.devfsd special character. Thanks for your feedback, Cheers, JF.
