Meta + T will show some pre-defined tiling settings and paddings, and using Shift + mouse drag it's possible to quick tile windows in these patterns

is it possible to replicate this somehow via keyboard ?

 

I want to change brightness based on which window is running, if its an IDE in dark mode increase, if it is a browser window decrease. The command itself is fairly easy to run even on wayland

qdbus local.org_kde_powerdevil /org/kde/Solid/PowerManagement/Actions/BrightnessControl setBrightness 5000   
qdbus local.org_kde_powerdevil /org/kde/Solid/PowerManagement/Actions/BrightnessControl setBrightness 10000   

how can I do it on a per app/window basis?

so it seems that without any config, the traffic passes from wlan1 to wlan0's network flawlessly; but traffic from wlan0 network stops at the Android device, even with iptables -P FORWARD ACCEPT, so I'm clueless on what to do next

how could I set up NAT like this ? thanks

[–] shadowintheday2 2 points 2 months ago* (last edited 2 months ago)

ip r

default via 192.168.15.1 dev enp3s0 proto dhcp src 192.168.15.32 metric 100
192.168.15.0/24 dev enp3s0 proto kernel scope link src 192.168.15.32 metric 100
192.168.38.0/24 via 192.168.15.21 dev enp3s0    
 

Ok I know this sounds crazy but it's all about Linux and iptables all the way

I'm using a rooted android phone as a VPN router to keep confidential traffic separated between networks

A and B are in the same network, B provides a separate network for C

Device A: Linux ip 192.168.15.32 wlan0 Device B: rooted Android phone with Termux and VPN Hotspot wlan0 ip 192.168.15.21 wlan1 ip 192.168.38.173

Device C: Windows 10 with RDP wlan1 ip 192.168.15.176

I've tried the following

A: sudo ip route add 192.168.38.0/24 via 192.168.15.21 dev enp1s0

B: Termux, su: sysctl -w net.ipv4.ip_forward=1


iptables -t nat -A POSTROUTING -s 192.168.38.0/24 -o wlan0 -j MASQUERADE
iptables -A FORWARD -i wlan0 -o wlan1 -s 192.168.15.0/24 -d 192.168.38.0/24 -j ACCEPT
iptables -A FORWARD -i wlan1 -o wlan0 -s 192.168.38.0/24 -d 192.168.15.0/24 -j ACCEPT

C: default route via 192.168.38.173 metric 1

C is solely seeing the internet from B's VPN, and can even access wlan0's router, meaning it has access to its internal network. C can ping B, B can ping C

B can ping A and C

A can ping B, but not C, which also means no RDP access

What am I missing ?

 

when pressing Super + Shift and moving the mouse around, the mouse act as a pencil drawing strange red lines

these stay persistent until I kill kwin_wyalnad_wr

Another section of the log when this happened:

Pretty much the title. I have been trying to pinpoint what's causing it and the proper logs, but the only thing in common so far in all times it has happened is firefox and another xwayland application are present.

logs show several errors, including this one - but how could I file a bug report, if I don't know how to reproduce it ?

Aug 15 17:09:37 hostname konsole[3721]: The cached device pixel ratio value was stale on window update. Please file a QTBUG which explains how to reproduce.

I'm using IPV6-able mirrors

is it possible to force pacman to use IPV6 only, other than disabling IPV4 in the whole system?

I realized it works in most programs, however it doesn't in xwayland

And it's precisely those xwayland programs (IntelliJ and Android Studio) that I would use this key most times

Is it possible to bind a key (e.g. context/menu key) as right click in KDE plasma on wayland ?

The real scenario lie between these extreme polar opposites of opinions

People new to a hobby (e.g switching to Linux) usually are more active and post more about their personal opinions and difficulties in the first months after getting into it. Then eventually the OS is just another thing working on their lifes, they move on to read and post about other things.

So what you read is usually the opinion of people who barely know what they are doing

If you want to switch, choose a way - any way is good enough - and follow through it. Choose any distro and desktop environment among the top discussed and you will be fine. Eventually you will understand that a "distro" is just a set of default configurations, and that the biggest differences are usually what package manager (the thing that installs/delete programs) and what Desktop Environment (the thing that display graphics and applications in a certain way) they use, and the same result may be achieved throughout most of them

Sure, someone helped me setting up a script to share the wl socket between namespaces so I can run GUI programs in isolated namespaces, and if you look at this post you can check the namespaced-openvpn; also check vole's answer if you want to run GUI programs

[–] shadowintheday2 5 points 7 months ago (3 children)

Thank you for summarizing it up

I've been using network namespaces in Linux where each one also use a different user; this way you can have multiple profiles of apps separated not only by permissions but also by the VPN connection that is the only route out

So you can have a connection that will supply your favorite iso sharer, a VPN connection to work, all unaware of each ot

I still haven't figured how to make GUI media applications work on them though

 

I'm using task switcher with Recently used sort order, but I still feel unsure if it's the same behavior

I didn't know memes could smell like they're old through the screen until I saw this one

Google logo before Corporate Memphis bullshit and the dude using a feet to hold his cup of tea just like the classical antiquity raptor, it's just perfect

 

I have created a network namespace to separate connections through a VPN, and it runs as the same user account as I use for everything else; however, it is not able to play music/use microphone

inside the namespace:


aplay -l  
card 2: Generic_1 [HD-Audio Generic], device 0: ALCS1200A Analog [ALCS1200A Analog]
  Subdevices: 0/1
  Subdevice #0: subdevice #0
card 2: Generic_1 [HD-Audio Generic], device 1: ALCS1200A Digital [ALCS1200A Digital]
  Subdevices: 1/1
  Subdevice #0: subdevice #0  


arecord -l

card 2: Generic_1 [HD-Audio Generic], device 0: ALCS1200A Analog [ALCS1200A Analog]
  Subdevices: 0/1
  Subdevice #0: subdevice #0
card 2: Generic_1 [HD-Audio Generic], device 2: ALCS1200A Alt Analog [ALCS1200A Alt Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0 

I also tried running as another user, but the effect is the same, which is why for simplicity I resorted to using the same user that can play/record normally

what should I look for in configuring it ?

 

I have 2x PCIe X16 and 1x PCIe 1x slots that are not being used. Given that Linux has extensive hardware support, there are probably users with interesting PCI card usages

Aside from traditional usages like network/wireless/bluetooth/sound that can easily be used as USB (or built in advanced sound support in the MOBO), what are your use cases with PCIe?

I was wondering if anyone else has had luck configuring SVP with MPV on wayland (AMD). I followed the archwiki https://wiki.archlinux.org/title/Mpv

This is ~/.config/mpv/mpv.conf

autofit-larger=100%x100%
hwdec=auto-copy
profile=svp
vf=format=fmt=yuv420p

[svp]
input-ipc-server=/tmp/mpvsocket     # Receives input from SVP
hr-seek-framedrop=no                # Fixes audio desync
watch-later-options-remove=vf       # Do not remember SVP's video filters
no-resume-playback

When SVP takes control of the video it pauses and never gets playing again

mpv stdout shows (pause) for a single sec, then proceeds normally, but the video stays frozen

[autoconvert] Converting nv12 -> yuv420p
AO: [pipewire] 48000Hz stereo 2ch floatp
VO: [gpu] 3840x2160 yuv420p

SVP has no option to control the video at all; it just says "playing whatever at 60fps"

 

Through amdgpu_top several modes are available, with [email protected] being the preferred

however after turning on/off the display, it reverts to 144hz

how can I make 160hz the default ? kde settings shows "A new output has been added. Settings have been reloaded" when this happens; and the previous 160hz is saved "for any display arrangement"
