Along with VRR over HDMI not being well supported, sometimes the monitors own EDID is a little buggy and Linux can't guarantee VRR will work properly.

I wrote a blog post a while ago on fixing EDIDs, but it was pretty much a guessing game on what to change: https://stevetech.me/posts/force-enable-vrr-edid

I've had to do that with both Samsung and MSI monitors so far. If you'd like to post your EDID, I could check it myself with what I know.

Epic!

I've never seen that on modern AMD stuff that uses radv, but I'm sure it's probably fine.

Yep!

Oh whoops yeah there is, run sudo update-grub.

But otherwise that config looks correct.

Cool, you're going to have to enable Sea Islands (CIK) support for amdgpu. You should just have to add radeon.cik_support=0 amdgpu.cik_support=1 to your kernel parameters. You're probably using GRUB so to do that you'll need to run sudo nano /etc/default/grub to edit it's config file, then add the above to the end of GRUB_CMDLINE_LINUX_DEFAULT (keep it in the quotes, but space seperated from the previous parameter). Then reboot and hopefully Vulkan works!

Alternatively, there's a section on the Arch Wiki for this, it should work fine for Mint too: https://wiki.archlinux.org/title/AMDGPU

Could you post the output of vulkaninfo including any errors that it might also print.

If it's not shown, what GPU do you have?

Also run lspci -k, is your GPU using amdgpu or the old radeon driver?

I think some people also use power_save=0 which would, but my understanding is 11n_disable=8 enables aggregating transmit packets together, which impacts latency but improves upload speed.

Do you have any FF extensions that might be interfering somehow?

I'm assuming it's a fresh install, so nothing of value was lost if the restore failed. But also I've heard attempting to delete things in /sys and /dev can brick your computer. So it's not a great idea.

Total Commander

I've started recommending Amaze, it's free, open source, and easy to use.

Although I still use Solid Explorer for myself, but only because I've paid for it and know how it works.

Both have SMB support, since copying files to and from my server is pretty much my only need for a file manager.

The HTTPS certs are designed to prevent MITMing, but if it's still a worry or the domain is blocked by DNS, you can manually find the IP and add it to your hosts file instead.

I'm not a radio engineer, but my understanding is you're just bouncing signals off the moon itself, there isn't a device that echos the signal back or anything. There are mirrors on the moon to reflect lasers back though.

A reverse proxy by itself doesn't do much security wise. You could possibly setup some sort of authentication, attempt blocking, and rate limiting (in the reverse proxy, don't trust the DVR), but it'll probably also break the DVR even more.

There's bots that port scan and specifically target all sorts of stuff, and DVRs are a very common target. With a VPN in the way, there's no way of knowing what's there. A VPN also shouldn't break the web UI.

I really wouldn't expose a DVR to the internet, and especially not RTSP, those sorts of things get brute forced all the time, and you can find websites full of hacked cameras.

What I would do is run a VPN server (maybe Wireguard) on your Pi, and VPN in when you want to look at your cameras.

It's probably blocked for whatever reason (maybe less than 90 days old?)

My work and Uni do the same thing, they don't do full SSL inspection, so most websites don't need a custom certificate authority; but if the SNI is blocked then they need a custom certificate to hijack and display a blocked message, most browsers will detect this as a MITM and display a not secure message instead.

Are you only using QEMU, or are you using some sort of wrapper around it? QEMU is quite advanced, if you aren't already, I'd recommend you use some sort of GUI like virt-manager or something.

Can you share your config?

Does it BSOD or just reboot after the Windows logo?

You might have to pass the drives through as IDE, Windows might not have the proper drivers for anything else. Once you can get it booting you can mount a blank drive as virtio, install the virtio drivers, and then change the OS drive to virtio.

Oh cool, I believe only 4bit colours are possible, you can use this table from Wikipedia and the escape sequence \e[<FG>m replacing<FG> with your chosen foreground colour. Also \e[0m to reset everything.

funny how we use the same font XD

Haha yeah! I noticed that too!

I think I just used regex look aheads and look behinds to insert the colours easily.

Edit: Oh you can change that actual TTY font to a bigger one, if the text is too small too.

You can do colours as well!

Most BIOS updates come with a firmware file and a .exe to flash it

Sadly in my case, iy doesn't.

I think they're saying the Windows update file will contain the firmware binary.

You can find Windows update files here: https://www.catalog.update.microsoft.com/Search.aspx?q=Acer

But you'll probably have to check each update and see if the "Supported Hardware IDs" match some sort of UUID in dmidecode. I'm not sure if those are supposed to match though.

Then there are some generic firmware update tools for Linux that might work, or might brick your laptop.

The unflipped version was also shared yesterday, for those who missed it: https://fedia.io/m/lemmyshitpost@lemmy.world/t/1017044
