General Discussion / Re: Backup program
« on: August 13, 2020, 04:24:26 pm »
I'm a rsync fan, too. To Keith's example, I'd add the parameter --delete which removes anything in the backup that no longer exists in the source.

It's a kernel module, so to check if it's there use
Code: [Select]
$ cat /proc/modules | grep xhci_hcd
xhci_hcd 135168 1 xhci_pci, Live 0x0000000000000000
usbcore 200704 12 uas,usb_storage,snd_usb_audio,snd_usbmidi_lib,hid_uclogic,xhci_pci,xhci_hcd,ehci_pci,uhci_hcd,ohci_hcd,ehci_hcd,usbhid, Live 0x0000000000000000
As you can see, I have it and it's running, and it depends on the usbcore module. It should be loaded into the kernel when Linux boots, but you can load and unload it:
Obviously the exact address in /lib/modules depends on your distro.

Whether you need a firewall depends on how you connect to the internet. If you have a modem/router plugged into the phone socket, or even to a fibre connection, then that device has a firewall and stops unsolicited things coming in. If you have a phone company's usb dongle plugged into the computer, so that it can dial up the internet without a router, then you do need a firewall. With Mint or Ubuntu, you turn it on with the command
Code: [Select]
sudo ufw enable
Give it a couple of seconds to sort itself out and confirm that it's OK with
Code: [Select]
sudo ufw status

A computer that can run Windows 10 can run any Linux, but Mint is always a good choice! Check the latest documentation:
The installation guide shows you how to  download and verify the installation medium, and how to put it on a DVD or USB stick — I think it's grown too big for a CD, if that's what you really have. The old CD will have the tools to do the job, unlike Windows where you need to download them, so boot it up into a live session and use it to prepare your installer.

That's a perfectly good computer for everyday use, but it's not fast: a 1.1 GHz Celeron is at the bottom of the Intel range.

I would not recommend Ubuntu — it would not be much faster than Windows. Luckily, with Linux you get to choose your GUI and they play a large part in determining how fast the computer runs. This explains the differences between distros:

As Keith said, you can take advantage of the ability of Linux to run off a USB stick to try before installing. I'd suggest you try the Mate version of Linux Mint. As you can see, it has great documentation — guides to installing and to using:

But by all means try Ubuntu too — you might love it. The user interface is more phone-like than computer-like, but some people like that. You'd want the long-term support version, as Keith indicated — 18.04 will be going until 2023.

While you're at it, you might like to look at Manjaro. That doesn't have versions — it's what we call rolling release, where you install and get regular updates until your computer dies of old age! Try yet another GUI with this one — Xfce.

You need to get a Windows program called Etcher to transfer the file you download onto a USB stick and make it bootable:

This seems to be a common problem. Sometimes it can be cured by just shutting everything down, including the mains power supply to the computer, waiting for a minute, and then starting up again! You say that the other USB ports are in use, but could you not free one up just to see if the drive runs off it? That would show if the problem is the port.

As that tutorial says, whatever disk burner you get with your distro should do the job. I have a thing called xfburn which starts by offering 4 options: blank disk, create data disk, create installation disk, and create audio disk. Simple!

CD players normally expect wav files, not mp3, so you need to convert them before burning the disk. Here's a tutorial:

Linux Support / Re: Switch to Linux Lite from Windows 10

Keith, is there any reason why you recommend unetbootin? Lite, like many other distros, recommends etcher:

Linux Lite  (and many others) recommends creating the installer with etcher these days:

This is very strange. It can't be a problem with the drive, as you've tried two. You could try using a different USB port to plug it in, or have you already done that? You could try a different LInux live disk and see if it's the software. That's what debugging is like — trying different bits until you find the guilty party.

It does make life easier if you have a distro with a lot of users, preferably including experts. You have a modern computer which will run anything, so you have a good choice. If you like the user interface of Lite, MX Linux is the same. It's very reliable and has a large community.

On the other hand, you may be able to get things sorted. That's often the best bet — you see people who have a problem with distro X, so they install distro Y, promptly have a different problem with than, and so go to distro Z … it gets endless, until they give up and go back to Windows.

Sorry I confused you — I assumed too much. Look at my fstab entry
Code: [Select]
/dev/sdc1 /media/usb auto noauto,noatime,users	0 0
We start with the device name. That can be a /dev address, a label, or a uuid — but not two of them. I've used a /dev address, but you don't want one because yours keeps changing.
Next we have a mount point. I use /media/usb because it's convenient for me, and I had to create it. You have been using /media/neil/data_neil1 which was presumably created automatically, but you could use anything, such as /media/data or /home/neil/data or whatever you prefer — but you do have to create it.
Thirdly, the file system. I use auto so that any flash drive will be accepted — you should use whatever fining system you have on your device, like ext4.

I find the computer's assignment of /dev a mystery — when I plug in a USB, it's always /dev/sdc, despite the fact that I don't have a /dev/deb — so I have no idea why the identification of your device varies. But I think the stackexchange article has the answer. I always assign a mount point for my USB sticks in fstab:
Code: [Select]
/dev/sdc1 /media/usb auto noauto,noatime,users	0 0
You could try doing that and using UUID or LABEL to identify the external drive, as indicated in the article. Whether that will end the disconnects is another question!

Linux Support / Re: ????????????????????? Swap.
« on: June 25, 2020, 04:54:55 pm »
Your memory usage is nothing excessive these days. With just Xfce and PaleMoon running in PCLinuxOS, I'm using 673 MB.

You don't want to be using swap unless the memory runs out, since it obviously slows down your computer. With a small memory, it's a matter of balance. If there's a lot of free RAM, then using it for buffers and caches makes the computer more responsive, but enabling that by using swap means you loose on the swings what you gained on the roundabouts.

A swap of twice the size of the RAM is a traditional setting that few ever think about changing. If you are going to use it for hibernation, then it needs to be slightly larger than that. Otherwise, I GB is sufficient unless you are trying to do something like video editing on an under-sized computer.
