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....

15.4 - Tbird 91 font size fiasco [work-around]

by David C. Rankin

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 -- David C.

18 Months Later - I'm getting list mail through suddenlinkmail.com

by David C. Rankin

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) -- David C. Rankin, J.D.,P.E.

Netdiscover - wrong source address

by James Knott

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. 172.16.0.92 96:60:ae:bd:84:7f 28 1680 Unknown vendor 192.168.0.67 38:59:f9:e0:7d:5d 254 15240 Hon Hai Precision Ind.

problem with MAX_DAYS_IN_TMP= ??

by jdd＠dodin.org

zypper ref says on my 15.3: Repository 'SUSE:SLE-15-SP3:GA' is invalid. I find in https://www.suse.com/support/kb/doc/?id=000018127 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 jdd -- http://dodin.org http://valeriedodin.com

Upgrade of 15.3 to 15.4 (beta? rc?) went fine

by cagsm

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

Thunderbird (and now Firefox) intermittently causing high CPU load

by gumb

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. gumb

15.4 Beta Report - All Good (2 Bugs Filed - 3 Bugs Fixed) Working Like a Champ

by David C. Rankin

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. -- David C.

list directory in ext4 filesystem

by Dave Howorth

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.

X virtual frame buffer

by Roger Oberholtzer

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? -- Roger Oberholtzer
