[RC3]: Misc Questions

[Bundabrg]

Hi All,

Just have some misc queries. My apologies if they are a FAQ or located somewhere, but with extensive googling I've been unable to find an answer to them yet.

Background
I have a C860, running pdaXrom Katherin RC3
90Mb Root partition, rest user
1Gb SD Card mounted /mnt/card
Till my wireless CF card arrives, I'm using the usb cable through my notebook (Debian Sid) running NAT iptables.

Questions
1. I notice that the silkscreen buttons are usable in RC3. How do I remap them to other commands?

2. I'm not sure if this is a problem with the ROM or something up with the USB network connection between the C860 and my notebook (Debian Sid). When I try to use ipkg (or even just wget) to get some ipk files (from the http://www.pdaxrom.org/feed2), when its uncompressing the file, I get the following error:-

Code: [Select]

tar: Skipping to next header

gzip: stdin: invalid compressed data--crc error

gzip: stdin: invalid compressed data--length error
tar: Child returned status 1
tar: Error exit delayed from previous errors

If I wget the same file on my laptop, and scp it to the C860, it installs/untars fine. Performing a 'diff' of the two files shows that they are different (though both have the same size).
I know that pdaXrom has an older ipkg and that some ipk are 'ar' files. The files I'm testing are definately tgz. Just so you know I've symlinked /home/tmp to /mnt/card/tmp so its got the whole 1Gb of SD avail for use (and I've tried the same thing with a 512Mb CF I've got here as well). My df  as well is:-

Code: [Select]

# df
Filesystem           1k-blocks      Used Available Use% Mounted on
/dev/mtdblock/2          92160     48016     44144  52% /
none                     12288         0     12288   0% /dev/shm
/dev/mtdblock/3          31744      1952     29792   6% /home
/dev/mmcd/disc0/part1   987720      1212    936336   0% /mnt/card
3. Is it worth upgrading ipkg to the newer one? If so, how? (This one I've been unable to find anywhere, just hints thats its possible by downgrading libc.so.6).

4. How do I access the F1-F10 keys.

5. Matchbox seems to allow right-clicks by simply holding a click on an item (like the old single button macs). However, this delay is sometimes really short (especially when using Xstroke as it cuts the letters in half). How do I change this delay?

Things I've noticed
a. RC3 definately has a slight screen flicker. It can be hard to see sometimes but at othertimes its quite noticable. (This has been reported many times. I'm just adding that I've seen it as well).

b. Sometimes auto-rotate doesn't work (Need to click it into the portrait/landscape mode twice for it to recognize the change).

c. Performing a 'dmesg' gives LOTS and LOTS of the following line: -

Code: [Select]

-W- Don't delete.
If I scroll back, the last lines from dmesg that are not like this are: -

Code: [Select]

devfs_register(part1): could not append to parent, err: -17
w100fb set 640x480 (VGA 90 degrees)
edit
d. When the screen blanks AND the pda is plugged into power, I can hear a high pitched noise, similar to the noise you hear if you put your monitor onto a frequency that is too high.

Final Word
Ok thats everything I can think of. Thanks to those who have helped so far and to those who have put all the work into these interesting devices. Its quite nifty to see my tetrinetx server run on a palm sized device .

I give you an up. Interesting thread... and I'd like to know how to remap touch-buttons too!

Agreed.  And I think those that don't see it just have poor eyes.    

Seriously, it's hard to notice if you don't look closely.  The whole image is shaky.  Maybe it is specific to C860?

I see a slight flicker on the (left) side of my 700 ...

I also get a "buzz" on some headsets when the AC is plugged into the pda.
the buzz sounds like bad grounding... or something.

Same thing on C760.

[scoutme]

no flicker here. Maybe I cannot see any flickering because of the poorness of my screenprotector.

Try increasing the brightness to the maximum -- then it flickers most.

[Mickeyl]

A flickering C700 is a symptom for an overclocked kernel. Disable the fast sysclock and the higher cccr setting.

4) The F keys appear to be turned off by default, you can turn them on again by remoiving the exclamation marks from the file /etc/X11/kb/corgi.xmodmap where the F keys are defined.

Fn-1 Fn-2 etc then become F1 F2 etc.

Thanks for the tip. Will look at that file soon.

Rest
Interestingly the screen flickers more just when you turn it on (probably makes sense). It stabalises a bit after a while, but still flickers, though when I show it to some others they can't see it at all. Doesn't bother me that much, just something to note.

[Bundabrg]

Ok finnally cracked it.

The important files are the following: -
 - /etc/X11/kb/corgie.xmodmap
 - /etc/xdg/openbox/rc.xml

The first obviously contains the keymap. This includes the silkscreen buttons, infact every button on the device including the screenswivel.

The second contains actions, ie the action XF86WWW (mapped in corgie.xmodmap to the web silkscreen button) is set to execute "dillo". Alsoo has stuff for how long a mouse being held down becomes a doubleclick. All I need now is to figure out how to map a key to a mouse button (i know, xkeymouse will probably be needed).

Here is my corgie.xmodmap (/etc/X11/xinit/.Xmodmap symlinks to this file). Its a modification of one provided by Foxdie. It maps the japanese keys to ctrl and alt.

3. Is it worth upgrading ipkg to the newer one? If so, how? (This one I've been unable to find anywhere, just hints thats its possible by downgrading libc.so.6).

Are you talking about my posts?

In that case, it's certainly not downgrading libc. If you use the ipkg package from the OZ 3.3.5 feed it'll work with pdaXrom (otherwise you'd have to *upgrade* libc). I found it better to use as I don't use the graphical interface (though it should still work fine) and the default version requires that the command line parameters come in a certain order (not the one I use), also ipkg-link and ipkg package installation failures are graceful unlike with the default ipkg script.

To install it, take the data.tar.gz file from the ipkg*.ipk package from the feed and just extract it over the current components (cd / && tar -zxvf /path/to/data.tar.gz) should work.

Before you do this you should note that I'm not sure how the control file syntax on the pdaXrom packages is formulated (I've had some troubles trying to install pdaXrom packages on OZ - not sure why, but probably because OZ tends to be more picky about the control file), therefore you may be better installing the OZ components by hand (with a different name for example) so you can still use the pdaXrom version if things won't install.
