I added new refresh rate for testing, but after enabling it I just get black screen.
How to fix this issue?
SDDM main process is running as root and ignores all policies. So only way is modifying SDDM source code(
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?
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.
Thank you, it works! But I got weird behavior:
- User sddm also cannot execute poweroff (it is ok) but if I press shutdown button in sddm it will poweroff (not ok).
- If I press shut down in KDE Plasma I will get black screen and no sddm (I can restart it with
systemctl restart sddmfrom tty and it will work again) How can I fix this bugs?
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.
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
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?
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.
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

Then I have the opposite question: why Apple won't open IPhones for side loading if it will feet more money?
If you're using an Intel chip look into GVT-g and consider running Arch from a VM, that'll be the closest thing to native.
I want to start clear Arch Wayland session on one my ttys and want to Arch have full direct hardware access.
The unfortunate thing about running an Arch container from a Debian host is that you're relying on an older kernel
I use latest Linux-libre on my Debian machine and everything works well.
If you are very, very lucky Arch will just work inside the container, but IME that's fairly rare as systemd often has breaking changes over several releases (and Arch tends to be at least several releases ahead of Debian.)
As I mentioned earlier I tried running Archbox. It is basically script to easy set up chroot. The main problem was that compositor couldn't connect to Wayland socket.
I installed WireGuard on my host and set this configuration /etc/wireguard/wg0.conf:

Upd. Fixed my changing server WireGuard IP to 10.0.1.1. 10.0.0.1 was already taken
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.
Hello! What is the best alternative to Telegram channels in Fediverse? I need platform where I can post messages in different topics and users can subscribe to them.
Hello! Is there any good FOSS Bitwarden Android app with Material You design? The official one is very ugly and laggy.
Upd: In latest updates native Bitwarden Android app is pretty good.
