power profiles
by Frederic Muller
Hi!
It seems i can only stay in Power Saver mode, balanced seems to be
clickable but quickly reverts to Power Saver and Performance is not even
clickable.
Any idea if there is any way to do that 'manually' as my laptop is
really slow now.
Thank you.

Vivaldi web browser - anybody?
by lejeczek
Hi guys.
Does anybody use Vivaldi?
I've had for a few years but have used it only for specific
subset of wwws. I've only recently noticed I do not get
sound during video playback, Youtube and others.
Can somebody confirm, using their yum/rpm packaged installation?
many thanks, L.

Fedora 37: kernel: general protection fault, probably for
non-canonical address PREEMPT SMP PT
by Dario Lesca
On a Fedora 37 up to date (kernel 6.0.10-300.fc37.x86_64), sometime I
get this error[1]
This problem occur often when I use nfs server from another PC, and if
I try to restart nfs via systemctl the command it remains stuck and I
must power off the PC
Other times PC freezes and I must power off and restart it.
Could it be a hardware problem (RAM? or CPU?) or I must fill a kernel
or nfs bug?
Many thanks for your help.
Dario

vim question - how to stop auto comments
by Sbob
Hi all;
Anyone know how to disable the vim feature where it auto comments all
lines after a comment, meaning if I add a comment line and then hit
enter for a new line I do not want the new line to automatically hace a
comment (#) char... it's driving me nuts!
Thanks in advance

Nvidia in F37
by GianPiero Puccioni
Hi,
I just update from F35 to F37 and everything is fine except I noticed that
instead of the Nvidia from RPMFusion it is using nouveau.
In fact the nvidia module is missing and wasn't built by akmod.
I think the problem is that it started with kernel 6.1.7 which is very recent
but it seems it's missing the kernel-headers -the most recent in the
repositories is 6.1.5- and akmod needs that.
There is something strange going on or I just should wait for the headers to
appear? Or maybe install 6.1.5 and use that?

Massive WireGuard performance regression on Fedora 37 vs Ubuntu 18.04
by James Wynn
I noticed a massive performance regression for WireGuard in Ubuntu 20.04 & 22.04, but it also affects Fedora. I don't know since which version.
Should I report this as a bug or did I mess something up?
I have fully reproducible steps to demonstrate this issue on a vanilla DigitalOcean droplet, minimal WireGuard configuration and no firewall rules. I've also seen this issue on other hosting providers.
Testing with `iperf3 -c XXX -P 5`:
- Unencrypted traffic on DigitalOcean's VPC = ~2Gbps
- WireGuard Ubuntu 18.04 = ~1.3Gbps
- WireGuard Fedora 37 = ~400Mbps
htop reported only 20-30% load on the vCPU core so it isn't CPU-bound. After doing these tests, I did them all again on a different day to rule out temporary network congestion.
Steps to reproduce below. Repeat with each OS version.
0. Create a DigitalOcean account.
1. Create two $6 droplets (eg, LON1 region) with Regular CPU & 1GB RAM each, called test01 & test02.
2. `dnf update -y && reboot`
3. `dnf install -y wireguard-tools iperf3`
4. On test01, create `/etc/wireguard/test.conf` with these contents. Replace `YYY` with the IP address of the eth1 interface (VPC) on test02.
--------------------
[Interface]
PrivateKey = wOEa8/RS2v065wgYGQn5k7FqOXuZJ9aC/6NDW569c3g=
Address = 192.168.200.10/24
ListenPort = 51820
SaveConfig = false
[Peer]
PublicKey = wdXOzBptLD/QMZjhG475GErrz95Vpj4S7JPEwzcDMV8=
PresharedKey = j5Oeyhu/qDag2LunpVlFqKycp/9CH+Izjza5aq2cYss=
Endpoint = YYY:51820
AllowedIPs = 192.168.200.20/32
--------------------
5. On test02, create `/etc/wireguard/test.conf` with these contents. Replace `XXX` with the IP address of the eth1 interface (VPC) on test01.
--------------------
[Interface]
PrivateKey = kCJ/4rVDTy86HxP9N5wUmgMF1Esqjc051jQPGhrQIGw=
Address = 192.168.200.20/24
ListenPort = 51820
SaveConfig = false
[Peer]
PublicKey = s/GtXkHOtPsqcNDy0BSRoMuxXYb4hK18dsQdkZk20yQ=
PresharedKey = j5Oeyhu/qDag2LunpVlFqKycp/9CH+Izjza5aq2cYss=
Endpoint = XXX:51820
AllowedIPs = 192.168.200.10/32
--------------------
6. On both droplets, run `systemctl start wg-quick@test`
7. On test01, run `iperf3 -s -B XXX`.
8. On test02, run `iperf3 -c XXX -P 5 -t 30` and observe ~2Gbps.
9. On test01, run `iperf3 -s -B 192.168.200.10`
10. On test02, run `iperf3 -c 192.168.200.10 -P 5 -t 30` and observe ~400Mbps.
In steps 7 and 8, replace XXX with the IP address of the eth1 interface on test01.

Change in behavior of libvirt networking
by Jeff Sadowski
I have a freepbx vm. A month ago it was working perfectly.
Then either a patch or me playing with docker broke something. ( I had
updated my system before starting to play with Docker
So the logs after the break show as follows
15018 [2023-01-25 18:53:59] NOTICE[32354] res_pjsip/pjsip_distributor.c:

provider ip)) - Failed to authenticate
Since I had started playing with docker and created an ipvlan. I tried
removing the ipvlan but the behavior is the same. I do not expect the (host
ip) to be in the logs at all since it is not sending that traffic. I can
ping the ip of the (obi200) with no issues. That is the device ip I expect
instead of the (host ip).
A long time ago when I started using libvirt
I had turned off Network manager on my machine and am using systemd to set
up my network.
In /etc/systemd/network/
I have 3 files 1-br0-bind.network, 2-br0-static.network and vr.netdev
# cat /etc/systemd/network/1-br0-bind.network
[Match]
Name=enp34s0
[Network]
Bridge=br0
# cat /etc/systemd/network/2-br0-static.network
[Match]
Name=br0
[Network]
Address=192.168.0.7/24
Gateway=192.168.0.1
[Resolve]
DNS=192.168.0.7 8.8.8.8
Domains=my.domain
# cat vr.netdev
[NetDev]
Name=br0
Kind=bridge
MACAddress=aa:bb:cc:dd:ee:ff
enp34s0 is my onboard ethernet
All my vm's used bridge type and connected to br0
Freepbx seems to be a little more picky.
For now a solution that worked for me was to use a second ethernet card for
my freepbx vm to use. Instead of bridge mode I selected direct attach. But
I would like to solve what happened so I can move it back to my bridge
interface I had set up for my vm's.

OT: xplanet cloudmaps
by Ranjan Maitra
Hi,
For several years, until pre-pandemic times, I used to download cloudmaps and overlay them on my xplanet. It was kind of cool, and also I could see some of the heavier weather tracking around the world. Then, I believe that that source got hacked and I never found a replacement.
This bug of desire to get back these cloudmaps bites me once in a while, and I have looked around and not found anything worthwhile and that still works (see https://krkeegan.com/new-free-source-for-xplanet-cloud-map/, whose replacement also appears to no longer work). However, I am not very good at DDGing online, but I was wondering if anyone had any experience/suggestions.
I used to use a perl script called download_xplanet_cloudmap that would go through a bunch of mirrors. However, none of them work and I get:
download_xplanet_cloudmap: ERROR: tried to download the file 6 times, but no servers could provide the file
I do get a clouds.jpg map which is of type:
clouds.jpg: JPEG image data, JFIF standard 1.01, aspect ratio, density 1x1, segment length 16
I doubt this is anything worthwhile, and in any case I can not figure out how to look at this jpeg file (JFIF?).
But I was hoping that someone had some experience with this old tool that is quite nice (and still supported by Fedora).
Many thanks and best wishes,
Ranjan
Btw, if you are interested, and do not know of this perl script, it is here:
$ fpaste download_xplanet_cloudmap

Netgear switches between networks
by Geoffrey Leach
Home network has two wi-fi sources (Starlink and Netgear, fwiw).
Occasionally netgear switches betwee primary (Starlink) and secondary
(Netgear) . I'm assuming that Netgear is trying to connect to the
strongest signal. Is there any way to tell Netgear not to switch
networks?
