Is it possible to exclude legacy x11 apps from system scaling ? (lemmy.ml)

There's one old game that works better by chosing "Scaled by the system"; however this make other x11 apps look slightly blurry. Is it possible to either choose "Apply scaling themselves" and exclude one app from it, or exclude every other app from "scaled by the system", so it only affect this one game?

Brightness resetting to 100% after powerdevil turns the screen off (lemmy.world)
 

title

before 6.3, powerdevil randomly did not answer to increase/decrease brightness after comming back fromm a screen off, and I got it fixed by running systemctl --user restart plasma-powerdevil.service

however now I get a somewhat different problem, the screen is always back at 100% brightness after a dimming and then screen off, although powerdevil is still responsive to increase/decrease brightness shortcut

it's not a laptop, and therefore there is only one power setting running on - AC - via DP

Has anyone else experienced this ?

Are there keyboard shortcuts to quick tile with padding like the Meta + T screen? (lemmy.world)
 

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 ?

Is it possible to run a script when a specific window is focused? (lemmy.world)
 

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?

Using RDP from Linux to Windows via Android and VPN in c/[email protected]
[–] [email protected] 2 points 9 months ago

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

Using RDP from Linux to Windows via Android and VPN (lemmy.world)
 

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 ?

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 ?

I'm using IPV6-able mirrors

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

How to right click with keyboard? in c/[email protected]
[–] [email protected] 2 points 1 year ago* (last edited 1 year ago)

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 ?

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

[–] [email protected] 5 points 1 year 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

Alsa multimedia inside namespace (lemmy.world)
 

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 ?

What PCI cards do you use ? (lemmy.world)
 

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?
