WiFi fails to authenticate several times.
by Jeffrey Taylor 17 Jul '22

17 Jul '22

I am using NetworkManager. When my laptop is opened after being suspended, it takes several minutes for the WiFi interface to come up. 'journalctl -f' reports several failed attempts to connect to the WiFi network: ul 17 08:48:27 viajero NetworkManager[1440]: <info> [1658065707.1758] device (wlan0): state change: prepare -> config (reason 'none', sys-iface-state: 'managed') Jul 17 08:48:27 viajero NetworkManager[1440]: <info> [1658065707.1762] device (wlan0): Activation: (wifi) access point 'Bearhouse' has security, but secrets are required.

laptop battery charging stategy (Plasma)
by gumb 17 Jul '22

17 Jul '22

I've heard and read many a time over recent years that the way batteries should be charged has changed. I've always been someone who lets devices run right down as low as I can before charging them back up to 100%. With one or two exceptions, this strategy still seems to work remarkably well for me, regardless of what others say. My previous Nokia phone would run for days under each charge, my current Android one goes five days or more between charges (I'm a light phone user), but conscious of this continual hounding from random people who may or may not be tech-inclined, and having both a laptop and a phone that offer flexi-charging options, I decided maybe I should change that strategy. So following a similar setting I just made on the Android phone, I set the Flexi-charging option in my Clevo laptop BIOS. It only allows adjustments in increments of 10%, so I set the lower Start point to 50% and the upper Stop point to 90%. Though I have a laptop, I almost always use it sat at my desk with it plugged in and hooked up to a bigger monitor and other peripherals. I like the versatility of taking my main PC with me on the odd occasion I go and stay with friends or family, but I don't frequent cafés with wifi because I'm not a hipster, and I'm terribly uncomfortable having the laptop on my lap or anywhere else. So for most of its life, it is plugged in being constantly topped up to 100%. Once or month or so I try to unplug it and use it on battery to let the battery drain and refill. When I do that, the laptop invariably throws a fit and suddenly warns about critical battery level even though it's still at about 45%, and switches off within a few seconds. I get these weird messages in my notifications: Message from syslogd@linux at Jul 3 15:34:04 ... kernel:[ 87.166486][ C0] Uhhuh. NMI received for unknown reason 20 on CPU 0. Message from syslogd@linux at Jul 3 15:34:04 ... kernel:[ 87.166498][ C0] Do you have a strange power saving mode enabled? Message from syslogd@linux at Jul 3 15:34:04 ... kernel:[ 87.166500][ C0] Dazed and confused, but trying to continue I don't think there's anything strange about my power-saving settings, it seems more likely the continual charging fools something in the subsystem as regards the actual charge level. Using flexi-charging is supposed to make battery reporting LESS accurate, but it's clearly already problematic. And usually, once I plug the laptop back in, the charge level shows back at 45%. So now having changed the BIOS setting, I see in Plasma (5.24) that the battery icon shows permanently in the system tray, because it's being constantly topped up... to 90%. I thought maybe what would happen is that it would decharge to 50% and then the charging would kick in and bring it back to 90%. I don't know if that would be better or worse, I can't see as hundreds of charge cycles will help, and in any case there's no options to set it to behave any differently, that would require additional software. Some of you must have a similar setup. What have your results been like with whatever charging strategy you use? I've had this laptop three years now and according to the Plasma Info Centre the battery health is at 94%, so it hasn't weathered badly. Should I abandon this experiment and disable the flexi-charging? The battery is replaceable anyway so if I really needed maximum battery life one day on this machine I could get another one. gumb

Anydesk not working on Tumbleweed
by Nicolas Kovacs 17 Jul '22

17 Jul '22

Hi, I'm currently experimenting extensively with Tumbleweed on a few VMs and a sandbox PC. So far, everything looks good, and I have a few details to work out. Anydesk works perfectly under Leap, but fails to install correctly under Tumbleweed, since it depends on some obscure legacy library which I don't happen to recall right now. So I decided to go for the Flatpak version. I configured the Flathub repository and installed com.anydesk.Anydesk. I restarted the PC (since it's my first use of a Flatpak app here), clicked on Anydesk in the main menu, clicked again on the Anydesk icon in the notification area, but unfortunately, the application doesn't seem to work. Has anyone had more luck with Anydesk under Tumbleweed ?

mouse problems OS 15.3, KDE 5.76, Nvidia GeForce RTX 3070 Ti
by Daniel Bauer 17 Jul '22

17 Jul '22

Hello, since two days (may since last updates?) I have strange problems with my mouse: it doesn't move smoothly, it's as it makes little pauses and then jumps to a next position. Or, when I resize a window dragging a corner, focus suddenly jumps to the window below. I changed the battery of my logitech wireless mouse, no change. So I changed mouse and USB-receiver for another mouse/receiver of the same model - same problems. All worked perfect until yesterday or the day before. It is not all the time, it started after some hours uptime, using gimp and digikam at the same time. I logged out and in again, but no change now. There is not much processor nor memory use according to gkrellm. temperatures are low. It's an intel i9 with 64mb memory. For what can I search (and where?) for hints for the problem, or does anybody have the same problem and knows what to do? -- Daniel Bauer photographer Basel Málaga https://www.patreon.com/danielbauer https://www.daniel-bauer.com

Kernel Security Update - RETBLEED - Can we turn mitigation On/Off?
by David C. Rankin 17 Jul '22

17 Jul '22

All, The kernel security update described on the announce-list listed the following, among other, problems addressed: The RETBLEED potential leak of info had been in the news the past week or so and a patch was anticipated. However, in discussing the fix, it can affect performance from 9 - 30%. Also discussed was it's "theoretical" use as an exploit to manipulate CPU branch prediction to glean information about kernel security details. - CVE-2022-29900, CVE-2022-29901: Fixed the RETBLEED attack, a new Spectre like Branch Target Buffer attack, that can leak arbitrary kernel information (bsc#1199657). My question here is depending on the impact to performance on any given setup, is there a kernel parameter we can pass at boot to turn it On/Off if the performance impact is severe? The second one is more of a chuckle and a wonder of just how long this bug may have existed - CVE-2022-33981: Fixed use-after-free in floppy driver (bsc#1200692) :) -- David C. Rankin, J.D.,P.E.

Custom default configuration for KDE : Taskbar vs. Kickoff
by Nicolas Kovacs 16 Jul '22

16 Jul '22

Hi, I'm currently experimenting with an OpenSUSE Tumbleweed VM. I'd like to slightly customize the default KDE configuration to eventually install it in our local school. No Ansible here, I just put everything in a bone-headed shell script with a handful of nifty functions: https://gitlab.com/kikinovak/opensuse/-/blob/master/setup.sh 1. Customize the taskbar ------------------------ The icons displayed in the taskbar are defined in /usr/share/plasma/plasmoids/org.kde.plasma.taskmanager/contents/config/main.xml. I changed that configuration with a series of sed one-liners, and here's what I have now: <default>applications:org.kde.dolphin.desktop, applications:firefox.desktop, applications:thunderbird.desktop, applications:libreoffice-startcenter.desktop </default> Now when my existing user logs out and logs back in, he or she gets to see this new default layout, with icons for Dolphin, Firefox, Thunderbird and LibreOffice in the taskbar on the lower left side of the screen. So far so good. 2. Customize the Kickoff menu ----------------------------- Now I'm trying to do the same with the Kickoff menu, which sports a whole series of icons in the favorite apps section. The default Kickoff menu is defined in /usr/share/plasma/plasmoids/org.kde.plasma.kickoff/contents/config/main.xml. Here's what my custom version looks like in the edited section of this file: <default>firefox.desktop,thunderbird.desktop,libreoffice-startcenter.desktop,org.kde.dolphin.desktop</default> Now here's the thing. This new customized default configuration is applied as expected for every *newly created* user. But only for those. Unfortunately *existing users* keep their initial configuration. I tried to figure out what configuration files keep the configuration of every user's Kickoff menu in ~/.config and/or ~/.local, but I think you have to be a member of some Secret Plasma Customization Cult to have access to this information. :o) Question: how do I apply my custom Kickoff menu configuration to existing users ? Any suggestions ?

Where do I create a bugzilla feature request?
by J Leslie Turriff 15 Jul '22

15 Jul '22

In order to allow a virtual machine guest exclusive access to a device (e.g. a GPU card), there is a long, involved process for configuring the system to exempt it from being connected to the kernel. I would like to create a feature request for something like a YaST module to do this, but what part of the system would it belong to? Two possibilities come to mind: YaST Boot Loader Which of these would be the right place to make the request?

15.4 - install dconf-editor to fix gtk3 file-chooser not sorting dirs first
by David C. Rankin 15 Jul '22

15 Jul '22

All, One annoying wrinkle with gtk apps in 15.4 is the default file-chooser does not sort directories first leaving an alphabetical sorting with directories and files jumbled together. There is a fix (regardless of the desktop you use), install dconf-editor and then set: org->gtk->settings->file-chooser sort-directories-first True Now things look normal in the gtk file-chooser. -- David C. Rankin, J.D.,P.E.
