Yes, pakt, that's all very fine, but I suggest you adopt a more rigorous engineering approach! Those pillars look as if they're 'as-cast'. Risky as they could penetrate that appalling plastic material you insist on using. Need to file the high spots machine-flat. Insert aluminium shims between your chip surfaces and pillar-top-shim combo using silver-loaded dag between all surfaces. You may need to use engineers' blue in try-out mode to align for position and thickness + pressure.
Overall, this is not a good configuration. Why do you want to put the little board in a case? Just screw it onto a piece of old melamine chipboard and leave it in free air - it won't hurt the dog, it only runs at 5V! You might get better cooling just by screwing an old PSU fan at right-angles at one end of the board to flow a faster airstream across the whole device. It really isn't rocket science; you can rely on manufacturers to come up with neat boxes for just about anything if there's a profit to be made.
Will try to post picture - didn't work last time! You've got it by PM! -tried twice more!!
Thanks TXD for your comments.

he wanted soundless, however a tester tried just a fan in a case ( no heatsinks )and got good results just a C or so above with heatsinks, what is your take on newest ceramic heat sinks? Wonder if they make small squirrel fans, they are extra quiet.

It's very difficult to have quiet and airflow, (cf. the jet engine!) Always compromises. Newer PSU s have bigger 4" or 5" fans which shift more air but a lower speed, less noise. With ducting and padding miracles may be possible but you may need to move into the shed.
Ceramic HS is an oxymoron - everyone knows silver is the best conductor, although copper is a close second (and copper dag used in motor engineering is readily available from motor factors and much cheaper).

Hello

I just installed the distro (8.1.2). Excellent
I added Dropbear. I can connect with Putty, WinSCP and from Ubuntu running in VirtualBox.

One comment: is it possible to add a Swiss French keyboard in the keyboard list (Quick Setup)?
In the meantime, I updated the file 10-evdev-puppy.conf (in /etc/X11/xorg.conf.d):

Code:
        Option      "XkbRules" "xorg"
        Option      "XkbModel" "pc102" #xkbmodel0
   Option      "XkbLayout" "ch" #xkeymap0
        #Option      "XkbVariant" "fr" #xkbvariant0


Thanks

Walter

I've successfully installed x11vnc. It has the advantage that a document
can be edited simutaneously on two machines --->
the raspberry pi and another linux machine. (I use fatdog 710 64 bit)

Quote:
x11vnc allows one to view remotely and interact with real X displays (i.e. a display corresponding to a physical monitor, keyboard, and mouse) with any VNC viewer. In this way it plays the role for Unix/X11 that WinVNC plays for Windows.



www.mydrive.ch

USER: porteus@don570
Password: porteus

x11vnc-v7-0.9.13.pet

_______________________________________________

Instructions:

1)install pet on raspberry pi
The other computer must have a vnc viewer
2) I suggest turning off firewall so that port 5900 will be default.

3)on raspberry pi you type 'x11vnc' in terminal
(Alternative: Type 'x11vnc -ncache 10' for more speed )
Instructions will be printed. The port that is used by x11vnc will be printed.
This is very important!! It is possible to have a password as well. Read instructions.

4) in other linux computer launch your vnc viewer app
and type

Code:
192.168.1.103:5900


where 192.168.1.103 is your raspberry pi network address
and 5900 is the port number. This is my situation. Yours will be different Laughing

One problem that I noticed is that my scroll-up and down keys don't work and my numpad doesn't work.

Here it is finally, a Service Pack, to upgrade 8.1.2 to 8.1.3:

http://barryk.org/news/?viewDetailed=00458

It is a bit "big" at 20.3MB, however that is because it has a new Linux kernel, up from 4.4.19 to 4.4.34.

Up until now, I was using a precompiled kernel, but yesterday I downloaded the source and compiled it.

...um, I had better post the details on my blog, that is, how I compiled it.

Have documented how the 4.4.34 kernel was compiled:

http://barryk.org/news/?viewDetailed=00459

There is a kernel source PET, so now anyone who wants to compile a 3rd-party driver can do so.

lost mouse control (non-functioning) after upgrade. On first reboot had a number of missing lib warnings. On a different version QX so if log files exist in broken updated version I can post them if you can tell me where those exist.
I used puppy package manager and updated for repos first. Also added a bunch of other stuff ( still working ok )prior to update if that could be an issue.
Backup first!

@Barry (and others) When you post links on your blog to a section of a thread, it would be helpful if you linked to the post (http://murga-linux.com/puppy/viewtopic.php?p=933824#933824
) instead of the page number which is completely useless if your profile is set to display most recent posts first.

Currently the following (intentionally unlinked) link takes me to the first post:
http://murga-linux.com/puppy/viewtopic.php?t=108132&start=390
in a day or so it will be the second page and a week or so later - who knows

You can get it from the little paper icon next to "Posted:" in the top left section of each post.... Bonus it will go to the exact post so no one has to go searching that page for it even if it is the right page.

Ha ha, after all these years, I never knew that you could show latest posts first!

OK, will remember that.

After installing the Service Pack, this file should have got created:

/audit/deposed/service_pack-8.1.2_TO_8.1.3DEPOSED.sfs

Click on that file to see what got removed or overwritten.
See if you can spot any of your missing libs in there, let me know if that is the case, and what they are.

Don't forget to click the .sfs file when finished, to unmount it.

I have just realised what the cause could be. The Service Pack installs /var/cache/fontconfig and /var/cache/ldconfig folders.

That might account for your missing libs problem.

If you are able to boot the broken system, maybe with "qfix=nox" in the kernel commandline, if X isn't working, then run:

Code:
# ldconfig


...if that fixes it, let me know!

ldconfig problem in Service Pack.

The 8.1.2 to 8.1.3 Service Pack has /var/cache/ldconfig/aux-cache

After a bit of reading, I found that this file gets created when you run "ldconfig".

Running "ldconfig" creates the cache file /etc/ld.so.cache. The other one, /var/cache/ldconfig/aux-cache, is also created, and this is used next time "ldconfig" is run, to speed up updating of /etc/ld.so.cache.

There is a warning about ldconfig crashing if that aux-cache gets corrupted:
https://bugzilla.redhat.com/show_bug.cgi?id=1325138

Quirky is unusual, in that the only thing inside /var/cache that persists after a reboot is /var/cache/fontconfig

So that aux-cache will be gone after a reboot.

Anyway, I have rebuilt the Service Pack without those /var/cache files, re-uploaded it:
http://distro.ibiblio.org/quirky/quirky6/armv7/packages/pet_packages-xerus/service_pack-8.1.2_TO_8.1.3-xerus.pet


If you have already downloaded the SP, please grab it again.
