Lately I've been getting an issue where out of nowhere the whole system just up and freezes, i can't click on anything or if I'm watching a video I can't pause it by pressing space bar. I checked the journalctl logs and it gave me this, but I have no idea what it means. My distro is Arch. Could anyone help me with this? I'd hate to switch to another distro or reinstall because of this, I already have everything set up just the way I like it and don't want to spend hours setting it all up again.

When I sshed into my server today, it said I had mail. I checked /var/mail/{myuser} and got a mail from caddy. The title was "SECURITY information for {hostname}". The message was this.

caddy : user NOT in sudoers ; PWD=/ ; USER=root ; COMMAND=/usr/bin/tee /usr/local/share/ca-certificates/Caddy_Local_Authority_-_2025_ECC_Root_31435960950297150297199787413716908247066220.crt

I'm still learning this self-hosting thing, I know enough to set stuff up but I still know barely anything about security, and the message looks kinda scary, so I would like to know what it means, thanks in advance. Note that I was messing around with Caddy and stuff yesterday, so maybe that has something to do with it, but I'm not sure.

Hi, I just moved to Niri. I turned on focus-follows-mouse on and turned max-scroll-amount to 100% in the config file. When I try to move to the next window by putting my cursor to the edge of the screen when the next window is a QT app, it doesn't work. Other apps work fine though, just QT ones. Could anyone help me? I tried searching this issue up but I couldn't find any info.

EDIT: Found the fix! Just had to add 1 to left and right in the struts section.

I don't know what to do. I've tried searching through google and all the answers don't seem to work. When I use Firefox (this is librewolf but it's the same on Firefox), games like Tetr.io or Friday Night Funkin lag real bad but they're buttery smooth on Chrome or Chromium. I have an iGPU and a "Cedar" AMD GPU according to lspci. Someone please help me, I don't wanna use Chromium just to get good performance. Please tell me if I need to provide more information.

I recently got a new Dell Inspiron 660s and it had Windows on it, I played around with Windows and eventually got around to putting Arch on it.

Now I've installed Arch on multiple systems but I'm no expert at Arch, I mainly like it because it's bleeding edge.

I opened Firefox on it and started to pull up Tetr.io and Friday Night Funkin - browser games, and it was noticably slower on Arch than it was on Windows.

According to Fastfetch, I have a "Radeon HD 5000/6000/7350/8350 Series" (???) and a "Xeon E3-1200 v2/3rd Gen Core processor Graphics Controller" (my iGPU i think)

What can I do to fix this? Please tell me if I need to provide more info.

I've been running my server without a firewall for quite some time now, I have a piped instance and snikket running on it. I've been meaning to get UFW on it but I've been too lazy to do so. Is it a necessary thing that I need to have or it's a huge security vulnerability? I can only SSH my server from only my local network and must use a VPN if I wanna SSH in outside so I'd say my server's pretty secure but not the furthest I could take it. Opinions please?
