Set custom refresh rate in c/linux@lemmy.ml

In this guide author dumped edid from disaplay and then loaded it without any modifications. So after reloading edid you can choose any resolution? Or I understood something wrong?

Set custom refresh rate (lemmy.world)
 

Hello! I am on Fedora 40 KDE Edition (Wayland). I have monitor with two supported refresh rates (60, 50 Hz). How can I set custom refresh rate? I know, on Windows you can use CRU.

[–] user_naa@lemmy.world 2 points 1 month ago* (last edited 1 month ago) (2 children)

Thank you, it works! But I got weird behavior:

  1. User sddm also cannot execute poweroff (it is ok) but if I press shutdown button in sddm it will poweroff (not ok).
  2. If I press shut down in KDE Plasma I will get black screen and no sddm (I can restart it with systemctl restart sddm from tty and it will work again) How can I fix this bugs?
How to switch Xorg to llvmpipe in c/linux@lemmy.ml

I think this is for applications not for graphical server

They all operates some way through systemd, so if operation is disabled via policy you cannot bypass it.

sasha@fedora:~$ /sbin/halt
Call to Halt failed: Interactive authentication required.

Desiable shutdown for users (lemmy.world)
 

Hello! Halt on Linux is disabled for average user by default. It will try to request sudo/root password and if fails returns:

sasha@fedora:~$ systemctl halt
Call to Halt failed: Access denied

How can I make same behavior for poweroff action? I know it is possible somehow via PolicyKit rulle

How to switch Xorg to llvmpipe (lemmy.world)
 

Hello! I have a very old PC with intel i915 graphics, which doesn't correctly display KDE and shows a lot of bugs. I know it is possible to switch to software acceleration in X server. On NVdia I can pass nouveau.noaccel=1 to kernel. So how can I disable hardware acceleration here? Maybe this is possible via Xorg config?

Libvirt USB passthrought via port in c/linux@lemmy.ml
[–] user_naa@lemmy.world 1 points 2 months ago (1 children)

No, this is not possible. Virt-manager is just a GUI over libvirt. For now libvirt doesn't support USB passthrought by port id, only by device id (which changes on each plug) or vendor id.

Libvirt USB passthrought via port (lemmy.world)
 

Hello! I need to create a VM and passthrought some host USB port to it. Sadly libvirt doesn't support QEMU built-in feature to use -hostport argument (which was added 10 years ago...). I tried to add custom arguments to domain (qemu:commandline) but this didn't work. When I just run qemu-system-x86_64 -device host-usb,hostbus=X,hostport=Y -usb everything works well. It seems like libvirt restricts some QEMU actions. How can I fix this? OS: Debian 12

Death of Piped? (lemmy.world)
 

Last two weeks every time I use Piped I am getting error "Sign in to confirm you are not a bot". It happens on every instance and videos work very rarely. It seems like Google enforces you to log in if you try watch lot of videos from one IP. I hope this will not be end of Piped and there will be solution for this problem.

Upd. I got similar problem on Invidious recently

Is there any good alternative to parted, that I can use in scripts? Parted main problem is that it requires user confirmation one each action.
