Pi 4 Model B 2 GB Rev 1.1 w/o a protective case around it:
... videos in full screen mode on my Dell screen (1280*1024) will rise the temperature to 58°C (w/o cooling kit)

Interesting. Older cpu's with BIOS usually offer limiting functions beginning at ~70C. Those processors, although larger, were a lot less efficient than the RPi s and drew relative large currents relative to feature sizes, so don't think 58C is worrisome? Notwithstanding, I have passive HS on all models 2, zero and 3, with a tiny fan on the GPIO blowing across the whole board, ie not just the CPU/HS, and haven't noticed any adverse thermal effects under high loading. Of course, the v.4 may be different, esp. as currents are quite high. Always remember that must specify where and how T^oC is being measured. Thermocouple on surface?,underside?SW? internal diode via SW?

Subject description: To buy or not to buy
 

Prior ordering my pi 4 I watched some/many yt videos comparing different ARM boards. I was thinking about using one of them
as a desktop replacement. You guessed it by now a 'VIM3' would be the one to pick. But how many people would come up with further
software for this kind of hardware? I decided to pick a raspberry pi 4. For ram size I decided to use 2 GB as I'm not sure if the 4 GB
version will offer me any more speed on the system. Using it as a file server 4 GB will make sense but watching videos and reading
blogs 2 GB should be fine. Using my pi 4 for four days straight I will give it a 75+% as being able to replace my BIOS PC's.
System runs very well on micro SD as well as USB 3.0 flash disk (working partition).

Hi FeodorF,

I was surprised to find that I could work in usb3 by just putting a copy of the pup on a USB stick or SD card and booting up.

I also found out that disabled SD cards could be brought back to life by defragging them using GParted.

Failed getting Stellarium to work, but if puppy manager is downloading old versions, as was posted earlier, it might explain it.

My Pi4 is working well as a mainframe, but can't access Canada government PDF Citizen files due to Adobe not working with Linux.

Regards. Tony.

hello tony,

I have a copy of Adobe_Reader-9.5.5-i386.sfs for 32 bit that works well on Puppy Linux...perhaps it will run on Buster Raspup, of course if you're working with 32 bit. But I agree, evince should work well also for viewing pdf's

Hi and thanks for coming back.

The citizenship ca website looks for an updated Adobe program and if it does not find it , it wont let you in.

Evince is probably fine but you would probably need to spoof it to look like Adobe.

Another example. Skype worked well before it was taken over by Microsoft.
Afterwards, not so good.

Changing the subject a bit. How do we get accelerated graphics?

Regards. Tony.

The site probably wants you to write info into a pdf file.
I guess only official Adobe program can do that.
You can go to local library.

Sometimes ARM Linux images come with 7-zip compression. - "No, not ours."

As I was looking for '7-zip' forum member 'mikeslr' had a solution for my problem. You can look it up over there:

Cutting edge stuff...

UBPORTS has been able to run its linux based OS on a raspberry pi 3+
but it runs out of space if raspberry pi only has 1gb.

..but a lot of issues

__________________________________________________


USB and wireless mice and keyboards work but selection remains odd.
Sometimes the mouse cursor seems trapped in an invisible box - moving it around eventually lets you reach other parts of the screen.
Often the area selected does not match where the cursor shows and clicking will select a previously selected area.
Moving the mouse repeatedly horizontally (or in some cases vertically depending on what you are trying to select) before clicking often works. Selecting specific areas of text is hard to get right.
The Pi touch screen works however there seems to be a linked issue, it easily selects areas that are difficult with the mouse but then fails at tasks like accessing the top pull down menu.
Repeated use of Tab then Return on the keyboard usually works when all else fails but is not a good user experience. Scroll wheel also seems reversed.

Hi, when raspup boots it shows me this screen and it won't move on:https://photos.app.goo.gl/DtvZycWc85t6SigBA
What can or should I do? I own a Raspberry Pi 3 A+

Subject description: Kernel panic
 

ggv94

Kernel panic is usually a result of a corrupted SD card or an incomplete installation.

If this installation was working ok and the error suddenly appeared on a later boot/reboot then most likely is a power cut - aka switching off the supply - before the OS had finished writing its housekeeping data at shutdown.

If it has never booted then (assuming your md5 sum checked out) something went wrong when writing your micro-sdcard.

I suggest you rewrite the card and make certain to sync (flush) before you dismount it.

Good luck,
