However, there is still some kind of problem.. installing dotpets and even sfs can cause issues (in xo-1)

That would be with your custom sfs or the original?

Ah yes, a 'howto' help file is needed, and not just for the olpc. There needs to be a a database in place with instructions for certain modems. While some like mine are very easy to set up, others can be a little more difficult.

Both the same, seems it may be related to which usb dongle I use, so not really a 'bug', will know more on the week end, less sleepy then Very Happy

Subject description: Guess that why it is called RC
 

Quote:
I would suggest to just try (re)installing udev from the ubuntu main repository through the puppy package manager. Just udev151(+), not any dependencies. Reboot and see if this brings sound back.


Tried did not work. Though I had power pet removed. I had to remove the power pet several times before the package manager did not list it as installed; likewise, had to install the udev151-12 several time before it was shown as installed. I rebooted each time after adding or removing but the packages did not install/uninstall properly?


BTW, "alsactl init" -- Reported no sound device

Ron, Mick
do you by any chance installed a package after you installed the powerapplet pet, and then the sound disappeared on next reboot??? Did you see 2 battery monitors at any point???

I think that the problem is that the pinstall.sh script re-runs every time you install a package. Since the the commands now spit errors (no files to remove no processes to kill) it hangs and on reboot the hanged processes corrupt the file system!!!

Is a wild guess but is this the case? Did you install another package after the powerapplet and before the sound issue?

BTW how do you remove (automatically) the pinstall.sh after installation

I didn't install the pet at all, I had it installed manually.

Also what rrslobe describes is similar behaviour to what I have seen with installing/uninstalling pets, even before powerapplet_xo existed, and yes, pinstalls seem to be the culprit.

Cheers

Let me get this straight because I'm a bit lost and looks to me there are more than one issues with the powerapplet(pet).

1) Manual installation of powerapplet gave you the sound problem without installing the pet. (BTW I'm still to see the sound problem)
2) When installing the pet and the pinstall.sh is left behind you get additional problems with the puppy package manager

Is that what you are saying? or is the pinstall.sh the only problem? And if it is how do you autoremove the damn thing since PPM does not appear to do it automatically (adding "rm /pinstall.sh" at the bottom of the script does not work for me)

I seem to have broken the shutdown.

It doesn't turn off. I get

olpc-switchd segfault at 0 ip b7767714 bfba807c error 4 in libc-2.11.1.so

Which I'm guessing is the powering-off failing horribly.

Other issues I've noticed. Using an external mouse doesn't trigger as a unblank worthy event. Which means you can be doing stuff and the screen goes dim. Not a showstopper, a tap on the touchpad and you're all ok.

Automatic network connection doesn't work. I'm not 100% sure it is supposed to, but I get the impression from the dialogs that it should restore connection on reboot.

And on the other front, I have been looking at where to plug in some bits.

In UDE I try to keep the users home directory relatively empty with the main things being Apps,Library,Downloads, and Stash
Apps for applications.
Library for unchanging media (pdfs,videos,music etc)
Stash for user created content
Downloads for acquired content.

For UDE on puppy I have elected to make a ~/Home(distinct from $HOME). I'll probably set up $UDE_HOME so that if people think it's a really bad idea it can be changed.

I'm going through the puppy apps and making ROX Wrappers as well as the ones I've customised for UDE.

mplayer -fs tv://
works (has a bug which causes a delay, but that has always been the case for me)

I have a tiny script for taking photos using mplayer that stores them in Stash/Photos/`date "+%d %B %Y"`/ It's a workable camera program.

I've also attached a font that may be useful. I built this because bitmap font rendering on the XO is so much faster, but all of the bitmap fonts I had encountered were way too small for the XO screen. This one is 21 pixels. Makes for a much nicer terminal.

more to come.

Subject description: I second the howto suggestion
 

We have tried to boot XOPup on the OLPC several times with no success. The last attempt was with XOpup-1.0_RC3 using variations of boot /usb/disk:\boot\olpx.fth , etc. Puppy Linux 5.0 is also on the same usb. Is that a problem? A clearly spelled out howto for this would really help. Thanks.

Yes, having another puppy is a problem. And that's pretty much the only problem I know of!

The how to is simple.
Expand the tarball at the root of the first partition (if multi volume) of any usb or SDcard that does not have Grub, puppyfiles (including the invisible aufs folders .wh..wh.....) or a "boot" folder and boot. Grub and boot is just to be safe.

Having said that, my preferred setup is on an ext3 formated SDcard with a swap partition and saving to the entire partition. Is much more stable albeit not as fast as saving to a file.

All these issues are in the "known issues 3" of the announcement. Eg the filesystem got corrupted during suspend.
The waking up from en external USB device is a limitation of the poewerd power management software when used with the non-hal version of olpc-kbdhim, as the one in XOpup.

Darn, still not clear. A howto with an example of what should be on the usb and what command to use in order to boot the usb would help.

The boot, boot10 and boot15 folders and the lupu-511.sfs file
To be safe just get an empty usb stick (though that's an overkill).

Fox7777 wrote:

There is no command.
Just plug it in an XO-1 or XO-1.5 and power-up the machine.

If is still not clear try again the build announcement and the formatting instructions included in the build.

there is a 'woops' with the announcement html file, a space in the filename, the browser won't open it Surprised , should be :

Announce_XOpup-1.0_RC3.html

--------------------------------------

More on petget issues later, but I have a gut feeling it is to do with aufs, no proof though.

Cheers

I have no "woops". The link in the top post works fine and the file in the tarbal also works fine. Just checked.
Did you refresh your Browser cache?

It could be... I think aufs it may also be responsible for the occasional fs corruption in suspend.
Anybody knows if aufs for the 2.6.35 kernel is better? There is now an olpc-2.6.35.4 kernel but is not mature/tested enough, so I'm afraid it may cause more problems than improvements. But if Aufs is a winner it may worth trying.

I meant in the tarball, I just tested, see screeny

Also, I just done a fresh install of Standard (no respin) of rc3 and then rebooted (after some net setup, swapfile etc on FAT32 [not as in Jeff Fatt Wink Wink ]), then installed your pet of the powerapplet_xo, no prob with sound, rebooted, still no problem with sound. Then installed seamonkey from quickpet, installed fine but I got 2 powerapp icons! (pinstall.sh re-executed, not deleted, also petspecs not deleted). Ok, will look at petget see if we can't workaround the issue, I think we should stick with this kernel/aufs patch for awhile and work out the bugs. I think I can fix the petget issues, same if an SFS has a pinstall too, should be fixable.

Cheers
