Learn 3 Linux areas, requiring increased AWARENESS, or even instant REACTION after UNIX-like OS installation.

I NOT tested big variety of Linux distros of course – but we can assume that there is some VERY bad habit across „some” distro lines, as in Arch (-Bang, Manjaro...)

1. NVIDIA proprietary threading – [Xid] bugs here: , seems similar to hibernation/s2disk problems

–a tricky issue, I  hope the env. combo helps: even when proper environment applied, FPS can be 1 (Xorg/glxgears) – see blog entry about „NVIDIA combo” [in testing]

2. CD/DVD/BD writer driver – also, here (Arch Linux with standard kernel, before KNOPPIX'ed) – its fault of Arch developers, even not to mention necessarity of placing some disk vendor id into some kernel internal hibernation special-treating PM list

KNOPPIX is so mature distro – replacing Linux kernel (contains basic [non-NVIDIA...] drivers automatically] across the distributions repairs even >1 problem. I not had to edit kernel source code in such manner!!!

 

They broke it overwhelmingly.

3. Hibernation/s2disk HDD spindown BEFORE even PC actually shutdowns – what a shame!! My blog covers it in basic details. Again, simplest way is replace it to the KNOPPIX kernel.

Do not forget about modules (drivers!) & recreating initrd. Maybe, also, some „extra” modules (in other directory... but all stuff under /lib/modules).

Along KNOPPIX-ation of the Arch, or other faulty Linux system, I recommend Fedora inside chroot/systemd's nspawn command, or similar. 

This one is user-mode solution – and the previous 3 was kernel-mode ones.

Fedora can be better than Debian, if you need GUI applications stability, and, as I assumed – the stability of package manager process.

 

No removing autoinstalled unneeded, blah blah... QGiS and Libre Office runs OK (remember, these are older versions – but usable, esp. when there remains LIBRE OFFICE bug with picture transparency/some image-op widgets BUG). 

All similar bugs shows you Babel/ity of social fragmentation – more precisely, the fall of America.

W/o PROPER religion you have no peace needed to fix the computer problems. To try, to wait, even to sit down with the machine. 

**Unconsequence** of Linux groups (multi BUGS) at Blender, LibreOffice Writer, *AND* LXQt file manager. IRRITATES. Mouse CURSOR not turning to „wait” shape in even BOTH ones.

I can't understand why, if there is such multiple coders of open source system, YOU CAN'T ORGANIZE SIMPLEST THINGS UP and does make Blender regressions bugs.

It can be very frustrating, I start to understand some sense of Gentoo system (and ABS).

The most frustrating is general philosophy of USA „lab”. You test, test, test – and, often still – have not. Even at code of Blender soft, one is bigger and more regressed than previous version (despite „news”).

Don't need animation lie, when basic rendering has still bugs.

In Bfor Artists /Blender 3.3../3.6... (...WHY mutating such versions' nums? Not a simple 1-1 string copy?? Are we computers or humans!!?? Data, data but WISDOM almost... none...), restarting scene demands gdb „r” relaunch.

•NEW Blender packages demands even more memory (for what?? Python language should be more as Visual Basic — when you start it QUICKLY).

And in Blender, there you make several meshes, lights (even without Par. Sys.), and .....

Still nowadays, BUGS ARE ON BASIS, despite Python revolution

 — FROM PEOPLE'S ADHD MINDS, that fail to comprehend that simplicity, practical aspect is more important than new sketch / grease ..cking new dragon scene.

„Ldsym” errors, as I name one category of OFTEN met Linux general bugs (after system usermode [!!!!] upgrade).

When man is almost certain that .so objs would be OK after new actualization (whole system upgrade), NEW, NEW CRASH. Even still, the ICU internationalization library demands its bash script, to the some strange point!

And.. New kernel??! What the f...k about nouveau, not loading (screen tearing) at newer RebbecaBlackOS ISO (GRUB) — a contrario???

Hybrid, hybrid, hybrid!!!! WHAT stupid hybrid society!!

Yea, Linux is really good at overriding M$ monopoly game.

—But what you need really and certainly does is a philosophy to coding opensource. Not such pokemons, snakes or Ukraine horror monsters that you render actually, stupid.

•LXQt is also, generally very good. Problem lies in.... LYING. So stupid strings that you don't have time... why the ....ing bankers does have time to challenge you??? Slaves colony.... .

As errors arise at installation upgrade, as at the programs runtime details. There must be some simple solution... .

•Some very interesting things I discovered. Gtk Window Decorator and Metacity's theme restores text in static application switcher (Compiz). Blender Bfor Artists with LUXCORE works OK if under gdb debugger (because of speciffic buffer overflow founds its redirection??.

•I don't trust even new Wayland „Xorg replacement”. Qt – OK, but what about GTK apps?

Damned „manually”: Clang «fast» Compiler still, 2024, NOT fully compatible with «gcc-code»: The nsxiv app’s compilation is one example.

 

Problem WAS, I updated some packages in Arch Linux and, after that, tried to replace old sxiv’s program custom enhanced variant to the new nsxiv from its git repository.

3 „old-fashioned” errors
— with fast Clang compiler, „new technology” of compilers, that are also accompanied (across… MULTIPLE Arch Linux packages) with the LLVM compiling orientation:

clang-16: warning: treating ‚c’ input as ‚c++’ when in C++ mode, this behavior is deprecated [-Wdeprecated]
autoreload.c:70:17: error: assigning to ‚char *’ from incompatible type ‚void *’
scratch.buf = erealloc(scratch.buf, scratch.len);
^~~~~~~~ autoreload.c:73:9: error: cannot initialize return object of type ‚char *’ with an rvalue of type ‚void *’ return memcpy(scratch.buf, filepath, len); ^~~~~~~~
autoreload.c:87:9: error: assigning to ‚char *’ from ‚const char *’ discards qualifiers
base = strrchr(filepath, ‚/’);
^~~~~~
3 errors generated.

Rerun make with old, „straight” gcc

 (by unset CXX & unset CC bash commands- and OK:

CC autoreload.o
c99 -Wall -pedantic -O2 -DNDEBUG -D_XOPEN_SOURCE=700 -DHAVE_LIBEXIF=1 -DHAVE_LIBFONTS=1 -DHAVE_INOTIFY=1 -I/usr/include/freetype2 -I/usr/local/include/freetype2 -c -o autoreload.o autoreload.c
CC commands.o
c99 -Wall -pedantic -O2 -DNDEBUG -D_XOPEN_SOURCE=700 -DHAVE_LIBEXIF=1 -DHAVE_LIBFONTS=1 -DHAVE_INOTIFY=1 -I/usr/include/freetype2 -I/usr/local/include/freetype2 -c -o commands.o commands.c
CC image.o

Yea, this one was simple.

 But generally, in IT world we have bigger projects that must be (re)compiled (or linked dynamically), DUE TO *.SO libraries issues.

There is no „hot” alternative. I don’t want the difficult special scientific system distrubution — I prefer to, AS WITH the icu lib, to put *ALTERNATIVE* libs in its special folder – not in /etc/alternatives but in /usr/local/lib/ICUxx, for example. While the icu library is the most wide, heavy alternative (Libre Office tends to link version after version of icu!!!), the (re)compilation of application turns out to be solution (as it was with BibleTime, also).

Some time ago, I replaced Arch Linux packages with the manjaro repo – resulted, not instantly but after update+manually, QGIS started working.

Previously I run QGIS from chrooted Debian system (that is, the container – not the VM nor similar, but live ability to change root directory – the SO objects are linked from distribution file tree).
