Hahahahaha I just suggested that in the original script thread.

If you are using my install ISO and update the kernel the default kernel will be the one that has just been installed.

Thanks BeagleBrainz I am burning the ISO now and getting ready to install . I will probably do a test tomorrow morning ( my time )

The thing to do, is when you update via the update manager, is deselect any kernels that show up.
In fact if you right click on the kernel packages in the update manager you can tell the update manager to ignore the updates.
In actual fact there really isn't a need to apply any updates if you are just testing. The system will run just fine.
Unless of course you intend to induce a stack over flow and execute "some arbitrary code" and give your self root permission. Or you're going to visit some dodgy websites.

Should get the same results, if you do it after the upload. Important is the same machine. I do not have access to any AMD X2 based machine. This could help determine why there is no temperature data. Be warned: I might ask more :-)

I am pretty sure another couple of Gigs of Ram would greatly benefit this machine

my1987toyota: my quick finds:

Mint:

Swap useage: prerun: 2556, running: 2600

Not much, bur still something. Conclusion: Add RAM.

Buster:

Swap useage: prerun: 0, running: 0

Looks like it is a "IdeaCentre H215". Nice, small thingy, I guess.

cache size	: 1024 KB

Looks smallish.

product: RS780L [Radeon 3000]

I had a raden 3450. Gave really bad results. Changed it for 45xx and/or 6xxx series: whole different world in latency, going from barely useable to good for soft stepping. Such GPU's can be obtained at around 20$.

cnc001@debian:~$ sensors
k10temp-pci-00c3
Adapter: PCI adapter
temp1:        +33.0°C  (high = +70.0°C)

That helps a lot. Thanks! I have to modify the script accordingly (lookup has to be for "core|temp", not only core). Maybe even add a check, whether there is any temp data at all would probably be nice. Better than to have to post the whole *.lat file. You could use:

tail -n2 <yourlatfile>.lat

and add this instead of the whole file.

seuchato I am glad it proved useful to you .

I had a feeling it needed more ram and I now have another 2 gigs on the way.

The H215 Idea center I am using has the graphics card portion integrated into the mother board
I will look into an add on card to see if it will help .

fortunately I wont be working on the PnP project for awhile so I have time to mess with the computer configuration
at least now when I plug in a usb camera I get video, I couldn't do that with Debian Wheezy for some reason.
