Like you I dumped Windows for similar reasons, only I went out and bought myself an *pple.

Never looked back. Three years of trouble-free computing, not yet needed to look under the bonnet like I did with Windows nearly every day.

Reading this thread though, Linux does not look able to compete with such stability. Mind you I'm just a retail user who wants to run a few mainstream apps on three synced computers and two printers in a trouble-free way. *pple achieve this admirably. Not convinced Linux could, given the amount of tinkering you chaps in here seem to need to do.

GIMP is the most comprehensive image editing program. It runs on Linux, Windows and OS X. DigiKam is a simpler package aimed at organising and editing photos. It has a less steep learning curve than GIMP. Nonetheless, GIMP is so widely used that all you have to do is ask Google what you want to accomplish, and you will get a series of step by step instructions. LibreOffice Draw is another simpler package that is useful for many tasks. Scribus is a full desktop publishing package, if you want that.

WINE allows you to run a majority of Windows programs on Linux.

I got the update for Lubuntu 20.04 a few minutes ago. I went ahead with the update but I hit a problem. I got a confusing window asking where I wanted to install GRUB. It offered the options of sda and sda1. I tried ticking each box separately. Both options were rejected. I ignored the warning the my system might not reboot and ticked both boxes, not seeing any other option. My system did not reboot needless to say. It went into GRUB recovery with the error symbol 'grub_calloc' not found. I did not have a clue what to do, so I asked Google. I found this:

https://askubuntu.com/questions/1263125 ... -not-found

The relevant post (dated a few hours ago) is:

Using Linux Mint 19.3 bios grub setup in a simple 2 partition installation.
After GRUB2 update the machine crashed on reboot and entered rescue mode.

error: symbol 'grub_calloc' not found
To restore GRUB I booted into Linux Mint 19.3 Live USB stick and issued the following commands in the terminal:

$ sudo mount /dev/sda1 /mnt
$ sudo grub-install --root-directory=/mnt/ /dev/sda

On reboot the desktop showed up nicely.

I booted from a live Lubuntu 18.04 USB and typed the two commands above. It worked, I was then able to reboot into Lubuntu 20.04. Perhaps it serves me right for having just posted that I have not had any update errors. :)

I have installed Xubuntu 20.04 on my Linux machine. I was not having any further problems with Lubuntu 20.04, but if it works, why not fix it? I have to say that I am impressed.

I did not encounter any problems installing from DVD to the SSD. I downloaded and installed Google Chrome and set it to be my default browser. Clicking on a link in LibreOffice opened the link in Chrome, which did not happen with Lubuntu 20.04. I also have not noticed the screen tearing problems that I had with Lubuntu 20.04. (They were fixable, but that is not the point.) I had a look at the boot time:

geoff@HP:~$ systemd-analyze
Startup finished in 1.409s (kernel) + 6.633s (userspace) = 8.043s
graphical.target reached after 6.616s in userspace


Xubuntu 20.04 beat Lubuntu 20.04 by nearly a second. The spelling checker for LibreOffice was downloaded automatically. On Lubuntu 20.04 there is not even a Language Preferences entry in the menu.

The memory used immediately after booting was 406 MB. That is only a little more than Lubuntu 20.04.

There does not appear to be any noticeable difference in speed between the two operating systems, but Mr Moneybags here has a £49 computer with a Core i3-3220 processor and 4 GB of RAM. It would be interesting to hear a report from someone with a more downmarket machine. Nonetheless Xubuntu 20.04 is a much more polished product than Lubuntu 20.04, and I doubt that there is any good reason for installing Lubuntu 20.04 in preference.

I found ShowFoto:

http://www.linuxandubuntu.com/home/10-b ... -for-linux

ShowFoto provides the DigiKam photo editing functions without the database functions, which suits me well. No problems installing it on Lubuntu 20.04 (it is a KDE application using the Qt library). I hit a slight problem when I tried to install it on Xubuntu 20.04 using Gnome Software. Nothing seemed to happen when I clicked Install, so I clicked Cancel. Software then showed it as Installed, but when I clicked Remove it said that there were no packages to remove. Software is notorious for that kind of behaviour, but I had not encountered it myself. No problem. I installed it via the command line:

sudo apt install showfoto

I was warned that the installation required over 600 MB of disk space. No matter. When I launched the application it took up very little RAM.

My Linux (Fatdog) boots from a USB stick, loads everything into ram, after which the usb can be unplugged. Boots the exact same every time, HDD is just for data.

For updates, I just boot, make the changes, perform a save and thereafter it boots with those changes/updates included.

Other than for a single session, can't be hacked. Data integrity is the main risk, regular backups to otherwise disconnected media addresses that.

The laptop I'm using was gifted as it was just too slow for Windows. Primarily because of the HDD slow spin up speed. When everything runs in ram, that's a non-issue (and runs really quick). For what data is read from/to disk the lag is acceptable.

It looked as though I still had a little screen tearing with Xubuntu 20.04, so I ran the test video here:

https://learnubuntumate.weebly.com/scre ... phics.html

That was right, and applied the fix given in that link.

When I installed Xubuntu, I selected install in place of Lubuntu, but I did not select erase disk. The boot partition is still sda1, but Xubuntu has been installed to sda5:

Code: Select all

geoff@HP:~$ df -h
Filesystem      Size  Used Avail Use% Mounted on
udev            1.9G     0  1.9G   0% /dev
tmpfs           383M  1.3M  382M   1% /run
/dev/sda5       110G  8.9G   95G   9% /
tmpfs           1.9G   46M  1.9G   3% /dev/shm
tmpfs           5.0M  4.0K  5.0M   1% /run/lock
tmpfs           1.9G     0  1.9G   0% /sys/fs/cgroup
/dev/sda1       511M  4.0K  511M   1% /boot/efi
tmpfs           383M   16K  383M   1% /run/user/1000

Gparted shows sda2 extended with sda5 appearing to be the extension. Selecting erase disk would have been less confusing.

As I said, earlier in the thread, for the 'buntus, it is not necessary to downgrade GRUB/GRUB2. You could fix the problem by reinstalling with the GRUB version in the repository which was said to be the latest version. Alternatively, a boot repair achieves the same end. The offending Ubuntu update not only addressed boot hole, but also several other boot vulnerabilities. With Lubuntu, I got another GRUB update and that worked. My freshly installed Xubuntu has not hit the problem.

I was thinking of trying out more linux variants than my trust Mine Mate 19. I got out an old desktop, which was noisy and sulked. I got my emergency windows laptop, which fought so hard to keep me out of the boot BIOS, then sulked. So I'm going back to trusty VirtualBox on my near-silent Quad core Intel i5 3.5 GHz, 16Gb machine I built myself.

How many virtual machines can I expect to run on it at once? I've been giving them 4Gb and a processor each, and have a archive team VM which does good works, and has 400Mb and a processor.

My preference would be to run up 3 VMs, the archive team one and 2 linux variants, is that likely to stress things, or could I do more?

I am still very pleased with Xubuntu 20.04. I do an auto-login so I was puzzled to see Xubuntu prompting me for password when I went away for a few minutes while my machine was running. I could not see anything in the Power manager that would do that. Then I had inspiration. I found that the Screensaver settings had screen lock set by default. The screen saver was set to a blank screen, so I did not know that I had one. The Floating Xfce screensaver is an absolute hoot, with the Xfce mice darting about. Of course, there is no technical reason for a screensaver nowadays. Their purpose was to stop CRT displays wearing out. Nonetheless, they are a nice retro touch.

Also from Quids Up (but without Miss Quids this time), a Xubuntu 20.04 review:

https://www.youtube.com/watch?v=xYnzqtPiK7s

I am running release 20.04.1 rather than the release 20.04 in the video. The AMD graphics problem should now be fixed (i believe it only affected multiple monitors), but I cannot test that. The problem with the cursor being changed by some snap applications has certainly been fixed. It is not great that these problems occurred 20.04, but it is good that they have now been fixed. In my experience, the Lubuntu team did not fix problems in point releases. A faulty LTS release remained faulty for 3 years, for the faults that I observed anyway.

I installed gedit as a snap from Software. It took ages installing the dependencies. I will install the deb version in future unless there is a good reason to do otherwise. The Synaptic Package Manager lists only the deb packages:

I have some corrections to make here. I ran:

snapd              2.45.2                      8542  latest/stable  canonical✓  snapd

My installed version of Google Chrome is not a snap. The problem where the mouse cursor changed colour entering a snap did not occur with gedit which is my only snap application.

I have become aware of the snap controversy. Canonical has made it so that if you install Chromium (and presumably other applications) using the apt package (or Synaptic), it installs the snap version rather than the .deb version. The Linux Mint team are not at all happy with this, and have removed support for snap (but you can restore it):

https://itsfoss.com/enable-snap-support-linux-mint/

I cannot say that I am keen snaps either. Gedit (which is a snap) is much slower to load than Mousepad (which is not). To Canonical's credit, Gnome Software does say that the version of Chromium in the store is a snap. It is possible to install Chromium as a .deb package, but it is not simple:

http://ubuntuhandbook.org/index.php/202 ... ntu-20-04/

There are some more interesting Quids Up videos here:

https://www.bitchute.com/channel/qbfNrk7CDLSU/

They have certainly prompted me to do some investigation.

I am still happy with Xububtu 20.04, but I decided to have a look at Mint 20. I burned Linux Mint 20 Xfce to a USB flash drive using Startup Disk Creator. I was not keen on the default appearance of MInt, and decided to experiment with the Appearance settings.

The Mint-Y-Aqua Style with Mint-X-Aqua icons looked best. The panel (AKA taskbar) was huge on my 1440 x 900 monitor, so I reduced its width with the slider in Panel Preferences. I still was not happy with the icons, and decided to install the popular Papiris icon set:

https://www.gnome-look.org/p/1166289/

https://www.omgubuntu.co.uk/2016/07/how ... eme-ubuntu

I found the icon set by searching for “papirus” in the Synaptic package manager:

https://geek-university.com/linux/synaptic/

The Papirus icons looked good, but did not blend well with any of the preinstalled desktop styles. I decided to install the more neutral Greybird Theme (which has been the default on Xubuntu for many years).

https://www.xfce-look.org/p/1016618/

I found the Greybird theme on Mint 20 by searching for “greybird” in Synaptic.

The the edushechkina_ladybird.jpg wallpaper looked the best of the Mint 20 wallpapers to me, and I have copied it over to my Xubuntu system. (I also like jankaluza_blossoms.jpg from Mint 19.2, and have copied that over too.) I installed the Papirus icon set on the Xubuntu system. ePapirus (the version for Elementary OS) gave the best contrast for the for some of the icons on the panel with Xubuntu 20.04.

On Xubuntu 20.04, increasing the panel width from the default 26 pixels to 28 pixels changed the colour of the Papirus “show desktop” icon from grey to light blue, and made some of the icons (including the Xfce mouse "start button") much clearer. The power saving icon then looked rather big though. I did not need that (it's in the menu anyway), so I removed it.

Linux Mint has its own Software Manager for installing applications. I found this tutorial on installing applications on Mint:

https://community.linuxmint.com/tutorial/view/1525

The recommendation is to run:

sudo apt-get update

in a terminal before installing an application with the Software Manager. I would have thought that would have been done automatically.

I like Mint 20 Xfce, although I probably only use about 2% of it's capabilities. I have it on 3 laptops (2 of which are ex XP/Vista machines and are pretty much redundant these days) and my Asus tablet/mini laptop. The Asus is an ex w10 machine and the other laptop is ex W7 which was 'upgraded' to w10. Both struggled to run W10.

Mint was like a breath of fresh air.

I burned Linux Mint 20 Xfce to a USB flash drive using Startup Disk Creator

I used Rufus, but only because that's what the instructions told me to use.

I use common applications found on Linux on my w10 desktops (Firefox, Libre Office) and I like the familiarity. MS Word was getting a little complicated for my likes.

Other than the Lemon, I find Linux Hint and Foss great resources for the Linux beginner / casual user

https://linuxhint.com/

https://www.fosslinux.com/

....as well as just typing your issue into Google. Someone somewhere will have a fix

I am still happy with Mint Mate 19, but after your praising Xubunbtu 20.04, I decided to look at it. I didn't like the toolbar at the top (I like menu bars at top, toolbars at bottom), or the double click to select application menu/application. I also tried Lubuntu and Ubuntu, but Ubuntu still has that cartoon interface, so I'm back with Mint again.
