I take that back, after a reboot the Eye-of-Mate image viewer is now displaying them as well.

No joy though for thumbnails in PCmanFM....got the packages installed and the pixbuf package specifically says in it's description "for programs like gpicview and PcmanFM". Gpicview no problem though, so that's good.

Finding some people online that claim it works for them though, and others like me it doesn't, looks like another puzzle to solve.

Can confirm both methods above work, GIMP export or Imagemagick in terminal.

Imagemagick doesn't list it as a supported file-type, but it works in terminal and file-manager right-click re-sizes that use the imagemagick backend also work perfectly for re-sizing.

I added the heif-gdk-pixbuf and the thumbnailer packages (in Mate) and now Caja shows thumbnails properly, and I can view the image in Gpicview but not in the Eye-of-Mate image viewer.

Oh no, you misunderstand me, I wasn't suggesting a workaround so you could look at my silly stuff, was suggesting a way for you to be able to host your Movuan images on sourceforge, as it's free and you get a large amount of storage.

@rolfie : Refracta2usb is your friend.

Though I do wish I could find a way to make it use the onboard isolinux in an iso instead of having to add syslinux on top of that.

Mintstick works perfectly with Daedalus too.

@RedGreen925 They have blanks for sale at most big box stores, I picked up CD's and DVD's recently at walmart. Also found a pack of 10 DVD's at a secondhand store for .99 cents a couple weeks ago.

I have CD's and DVD's I burned going all the way back to 2007 that work fine, just need to store properly and be careful when using. I like having a non-electronic backup for my work and important stuff. Have worked with electronics all my life, and seen too much fail to put all my faith in such.

And yet again we see the superiority of the optical disk, as it never fails.

I don't use the OP's method to run pure alsa, but I can attest that FF works for me just fine with nothing but alsa. All the browsers i've tested do.

For me, I still have fully functional ISO's of pure Jessie that are all GTK2, archive repo is still available but I have everything I want already, the only program that needed a modern version to work properly was the browser, so I use an appimage of FF. No frankensteining needed.

Microsoft, Apple, and Devuan walk into a bar.

Bartender: "We have a special today on our super secret house specialty drink, like to try it?"

They all agree to try it. Bartender walks up to a huge machine with all kinds of dials and switches, flips a bunch of them, then punches in a code. Then brings them their drinks.

Microsoft: "We would like to buy the recipe for this drink, but you must sign an agreement never to disclose the recipe".
Apple: "We would like to buy the recipe AND the machine but you must sign a binding agreement to never give it to anyone else".

Devuan: "Why are you using a recipe or a machine? It's a friggin' gin & tonic, I can totally make you another one if you want".

No offense and the thing to remember is that everyone's tastes are different, but spacefm has been awful in every version i've tried, vanilla PcmanFM is better in every way.

"Power-users" are a very small minority of the computer-users world-wide. And if you are among that minority, then you have the capacity to build yourself whatever works for you. I suggest you do that.

For most folks, the whole "workspaces" thing is completely wasted. As for myself that's the first thing I delete. I don't need 2 panels, much less 4, that's the second thing I delete.

I've converted hundreds of former windoze users to Linux now, and every single one of them preferred a familiar simple interface, one panel at the bottom of the screen, no "workspaces", simple menu, easy and intuitive for people who don't live to code.

Gnome-2 and Mate were that bridge for a lot of people myself included.

New update of the ob-max-z uploaded today, minor security upgrades and Chromium updated.

Added qt5-gtk2-platformtheme package and an .xsessionrc file with an entry that makes
VLC (and any other apps that use QT5) abide by the chosen GTK theme. Working on doing the same
for QT6 apps.
