Hi - I have a number of openSuSE 15.3 x64 that periodically experience
bad sluggishness in responding to keyboard or mouse input. This can get
frustrating with delays up to a minute or so after clicking on a button,
or typing in a window. This occurs across all applications/windows open
on a KDE desktop. Ksysguard aka System Monitor, nor top, do not show my
why these slowdowns occur. I monitor CPU %, I/O Reads/Writes, Network
activity and don't see anything indicating abnormal consumption of time.
So given the fact that I am NOT a guru on Linux systems, what else can I
do to try and track down (and hopefully fix or find a solution to) what
is going on with my computers. What strategy(s) should I follow and what
other tools might be helpful? Thanks for any advice/help in advance....
Marc....

All,
One giant headache moving to Tbird 91 (aside from the loss of enigmail and
the screwy way gpg keys are handled) is that font sizing just sucks. Nothing
works to set the folder pane (tree) or thread pane (tree) to something
readable. The new approach is to have you use the aboud:config editor and set:
layout.css.devPixelsPerPx
( 1.0 is base, can go in increments of .05, etc.. to grow or shrink interface
font size)
However, in reality all this does is stretch the line height and there is
no independent control of the folder pane and thread pane. So if you want to
increase the size of the message list (thread pane) you end up making the
folder list too big and vice versa.
The problem is Mozilla, in true Plasma or Gtk4 fashion has removed the
ability to set the interface elements through userChrome. The did so by
disabling the following by default:
toolkit.legacyUserProfileCustomizations.stylesheets
The good news is you can set that to true and have the userChrome file read
by Tbird on start. This will restore the ability to adjust the font size of
the folder pane or thread pane individually, e.g.
/* thread pane font */
#threadTree > treechildren {
font-size: 9pt !important;
font-family: sans-serif !important;
}
/* folder pane font */
#folderTree > treechildren {
font-size: 8pt !important;
font-family: sans-serif !important;
}
After wasting an hour playing with various approaches I stumbled onto the
following answer on Unix & Linux on StackExchange:
https://superuser.com/a/1678336/439609
Hopefully this will save someone else the wasted hour trying to figure out
why what has always worked for fonts no longer works in Tbird 91

All,
I don't believe it, but beginning day before yesterday, I started getting
openSUSE list mails through suddenlinkmail.com (factory and users).
Par for course. Trouble ticket opened 9/2020, and just now fixed! Go
figure. Thanks to Patrick and rest for keeping mail flowing before I gave up
and went to gmail.
(will leave both accounts up for a week or so to make sure this isn't a fluke)

I recently installed netdiscover and noticed by default it uses the
wrong source address. I set the range to my home LAN (172.16.0.0/24)
and when I run it, it shows a source address of 172.16.0.67 on my
desktop computer, which should be 172.16.0.10 and my ThinkPad
(172.16.0.40). I can force the correct address with the -n option.
Also, when I get a capture, it shows some, but not all of the devices on
my LAN, but also several lines of nonsense addresses such as
192.168.0.67, 192.168.1.67, etc., all with the MAC from the computer I'm
running it on.
Here are some examples. Only the first line is a valid address.

That Hon Hai name also is shown on the valid address for my ThinkPad.
Has anyone else experienced this?

zypper ref says on my 15.3:
Repository 'SUSE:SLE-15-SP3:GA' is invalid.
I find in

Resolution
Please clean up temporary directories in /tmp or /var/tmp. Do have the
system clean up these directories on boot please edit
/etc/sysconfig/cron and change the values for:
but in this cron file I see
## The Parameters MAX_DAYS_IN_TMP, MAX_DAYS_IN_LONG_TMP, TMP_DIRS_TO_CLEAR,
## LONG_TMP_DIRS_TO_CLEAR, CLEAR_TMP_DIRS_AT_BOOTUP and
OWNER_TO_KEEP_IN_TMP have
## been converted to systemd-tmpfiles settings in /etc/tmpfiles.d/tmp.conf.
## Please check and modify to your needs.
## See 'man tmpfiles.d' for details.
there is no tmp.conf file on my 15.3 install and the tmpfiles.d man page
is not that clear for me.
any help?
notice than cleaning the tmp dir manually didn't help (but I can't
reboot just now)
thanks

Users,
upgrading online some 15.3 to 15.4 just today (beta? rc?) via zypper
and golbal parameter --releasever=15.4 went fine over here with a
rather simple test system.
Too bad 15.4 is very conservative and old in various software versions
and so on. Is a tumbleweed more suited when not wanting to risk
stability and not opting in for data loss?
ty
I'm on Leap 15.3. Held off the update from Thunderbird 78esr to 91esr
for quite a long time because I'd read of one or two issues and knew it
might be best to wait a while.
Now, let me state that I've been using Thunderbird since pre-1.0 days
about twenty years ago. It's always been rock solid stable, sometimes a
bit old and clunky but absolutely reliable, more so than just about any
other software I use. I also understand that open source developers
don't get enthused by criticism and they give their free time and energy
and we should all do our best to show appreciation and be constructive
in our conversations and hug trees.
With that said, all current Thunderbird developers must die!
Okay, I'll back off a bit. After twenty years of rock solid stability I
upgraded to 91esr and have run into a catalogue of irritations, some of
which I should have actually catalogued because I've now forgotten for a
moment what they are, but I'm sure they'll come back to haunt me some
more. In the v91 release notes I see lots of happy-clapping for spangly
new features that are of no relevance to me. I just want the continued
stability.
Somebody already remarked on here some time ago that scrolling in the TB
message preview pane is now horked. I either have to click or move the
mouse about erratically in the pane to get it to scroll. Sometimes it
scrolls immediately, other times not, and seems worse when there's
images in the mail but no consistency or logic to it. Tried turning on
hardware acceleration and for an hour or so thought that had cured it,
only for the problem to return many times since.
One or two other smaller annoyances I'll just have to put up with for
the time being, but I'd like to know if anybody else has witnessed high
CPU usage, specifically in Thunderbird 91esr on Leap 15.3? I wondered if
it was continually reindexing my twenty years' archive of folders, and
at first it seemed to do it fairly routinely once a day in early
evening. But then it became more frequent, and now it spins up several
times a day. This laptop has been ultra quiet for three years. 8 cores,
32gb of RAM, all of which I barely use. Bought it secondhand-like-new
and it's way overspec'd for the mostly mundane tasks I require of it.
Only very rarely does a CPU intensive task spin up the fan and make any
noise noticeable, briefly. But now Thunderbird is doing this
consistently. At this rate, it's going to wipe two years off the
lifetime of this machine.
I do NOT have the global search and indexer feature enabled. I tried
deselecting and reselecting it as OFF just to make sure. If I look in
Plasma's System Activity when the high load occurs, I see Thunderbird
showing typically between 6 and 22% CPU load whilst most other processes
are rarely pushing more than 1 or 2%. There may be subprocesses amongst
the bazillion other kworker and whatever garbage things further down the
list, but I can't pick out anything for sure. Nothing that nudges more
than a percent or two.
It's also not the Compact Folders process, because I still only do that
manually after a prompt. It just prompted me for the first time in a
long while (I have it set to only act with over ~200mb wasted space),
and after that ran for a few seconds, my system just went into some kind
of hyperdrive like never before witnessed, whilst Baloo reindexed for a
few minutes and half the neighbourhood lost power to the centrale
nucléaire whilst Mr Linux plays with his email client.
And now Firefox has decided to join in the fun and games. Again, the
standard latest ESR version for 15.3. Most particularly when I start
playing anything in YouTube, but not uniquely that. System Activity
usually shows a process 'RDD' consuming one core, and my fan starts
going into warp speed again. Never happened before this last week or
two. In both Thunderbird and Firefox I've turned off all studies, data
collection, error reporting and whatnot to eliminate that.
It could be that others have these symptoms but don't notice on their
desktop fanless or soundproofed machines. What could be the cause?
No I haven't yet filed any bug reports. I'm unsure if it could be
openSUSE-specific, perhaps some other dependency like a graphics update
that has nothing to do with Mozilla. Too many vague things to know where
to even start. And no I haven't tried creating a blank profile because I
can be almost certain nothing will go goofy in such an empty profile,
and I don't want the inconvenience of setting up and receiving pop mail
in a fresh instance and then having to merge it all back into my main
mail at a later date.

All,
Short report on 15.4 Beta, after relatively smooth install, ext4 w BIOS
Boot, / and /home, Minimal Desktop, (IceWM), Addition and install of KDE3, two
bugs filed:
* https://bugzilla.opensuse.org/show_bug.cgi?id=1199473 (Not a kde bug -
Gnome stripped subcategories from xdg menu (grab 15.3 package)
* https://bugzilla.opensuse.org/show_bug.cgi?id=1199643 (both icon-select
and shortcut dialog issues - FIXED; Yasuhiko Kamata has been a Rock Star)
While I haven't gotten to cinelerra yet or kdevelop, etc..., all other
desktop aspects:
* libreoffice, Tbird, FF. gcc-7 and gcc-11 installed and working fine.
* OO calc has a full-screen hang if launched on first use through the calc
icon, but launching libreoffice starts windowed and choosing calc there opens
calc windowed setting whatever wasn't set causing hang.
* goal of Qt4 removal may be a bit premature, issues remain, but
factory:frameworks5 repo contains all qt6-4 libs, so there is a ready
workaround while the transition takes place.
* No showstoppers, great job all and kudos to the openSUSE/SLE devs.
Looks like 15.4 is a keeper.

Is there any way to display the contents of a directory in an ext4
filesystem? I don't mean an ls, I mean a byte by byte inspection of the
actual directory structure.
I have what is apparently a rather large directory, which is also empty:
$ ls -ld files/
drwxr-xr-x 2 motion motion 3215360 May 9 00:55 files/
$ ls -l files/
total 0
od for example won't open it:
$ od files
od: files: read error: Is a directory
0000000
it's on the root filesystem which is supposedly clean:
$ sudo e2fsck -n -v /dev/root
e2fsck 1.42.5 (29-Jul-2012)
Warning! /dev/root is mounted.
Warning: skipping journal recovery because doing a read-only filesystem
check. root: clean, 90733/897600 files, 1419737/3583744 blocks
(it's a rather old SD-card-based system I'd rather not reinstall)
I'm tempted to just delete the directory and recreate it, but I'd like
to understand what happened first if I can.
I have a headless 15.3 system that I would like to access remotely. I
need access to the desktop (i.e. X).
When there is no display attached, X does not start. I wanted to
install xf86-video-dummy, but it complains:
error: Failed dependencies:
X11_ABI_VIDEODRV = 25.2 is needed by
xf86-video-dummy-0.4.0-lp153.24.1.x86_64
So I am guessing that X on 15.3 has recently changed the ABI. The
installed xf86-video-* were built on May 2019. Note that these were
still the ones that eventually were installed on Feb 2022.
Unfortunately I did not install the dummy driver at that time. The
change seems recent.
As an alternative, I see that one could add some config to X for this.
I read mixed things about how that works in terms of systems not
booting.
I also was considering xrand (xrandr --fb 1280x1024 -display :0).
Seems starting that via ssh can be iffy depending on how it is
handling X. So I have not been able to test it. If I make it start
when the system boots, could it do anything to keep the system from
booting?
