please dump any small browsers you know about, i’d like to try them out

the two i can think of are emacs’s eww and links (text mode). eww has been surprisingly useful, even without js support and extremely barebones html rendering

this is eww:

and this is links:

sadly, neither is able to login to lemmy, but I was able to login to mastodon through brutaldon

Sorry for a rant against Windows in a linux community, though this feels like best place to rant.

I recently started work on Windows, and I expected everything to just work well. After all, that’s the point of Windows! It is the first-class citizen, where things work out-of-the-box.

Yet my experience wasn’t so great.

1. Printers, the bane of IT. HP has dedicated drivers to it, which they should support well. It should JUST work, right? Right?? No, it randomly fails to detect printers, says a printer is off, reports missing papers when it has enough, fails to print a normal document while being able to print test pages. It also seems like driver-OS communication is not quite great, as they often give different status.
2. While in a zoom meeting, I plugged in my earphone. Then, zoom froze. Really, how can plugging an earphone cause a freeze? Even quitting zoom and re-entering did not work. In the end, I had to turn my computer off and on again, and couldn’t use my earphone. It has been quite embarrassing and enraging experience. What a disruption from something which should work out-of-the-box…
3. PuTTY and WinSCP is way more clunky than ssh in terminal. I don’t like the GUI with decades old visual, with confusing settings here and there. Each app having separate terminal turns me off as well.
4. Windows 10 does have multiple virtual desktop support. Yet funnily enough, clipboard contents do not transfer across virtual desktops. Who thought this is a good idea??

Basically, hardware support is still hit-or-miss with Windows (I thought this was linux-only issue), and connection to linux server is not so stellar. How can people love these?

As things currently stand on my #KDE system, I have a login script which runs a while loop listening to d-bus events for system unlock and then restarts my #plasma-shell and plasma.power services, so that I don't lose the Desktop Environment or Keyboard control of Monitor brightness.

In another life, I would be trying to upstream fixes for these. But not in this life.

I finally got a Linux VM to run in Hyper-V on my Windows ARM laptop. The workaround is to only give the VM 1 CPU, any more and it runs significantly slower for each one added.

Pictured is a fresh install of Chimera Linux.

For context Autin (Github) is a shell history replacement that apparently provides a lot of extra functionality.

Has anyone used it? Im thinking of switching to it but Im worried about its impact on performance and if its worth it.

Here are the results for the community poll I ran last week, on #Linux desktop and WM customization.

The results were a bit surprising to me, and seem to indicate that while a lot of people take advantage of the various layout options, themes and icons don't get changed a lot:

Hello everyone :).

Trying to keep it short, cause after 2 days of troubleshooting I’m a bit tired and really confused on what happened here… Maybe it’s my lack of understanding about Legacy BIOS/UEFI/EFI/Bootloader/GRUB… But that was really an odd “issue” that resolved by itself?

Intro

My 15 years old laptop, an Asus N76V, is still going strong, though It’s purpose is not the same as a few years back. It’s working great as a mini-server to host docker containers, DNS server, firewall, wireguard tunnel…

Space left on my volume group (LVM) was getting tight so I decided to install a new Samsung 1TB SSD into it’s second slot. As easy as it is, I though this would not take more than 30 minutes…

Old SSD just vanished from boot option in bios.

After booting into BIOS to see if the new SSD is recognized, everything seems okay, however my primary SSD containing the Bootloader and system just vanished as boot option?? I was not to angry about it because if something strange had happened and everything got wiped for whatever reason, I still have my daily backups, so the troubleshooting begins…

Things I have tried so bring my primary SSD back as boot option in BIOS

Though my secondary and new SSD shows as boot option, it’s empty and has no Bootloader or system installed.

1. Change a lot of things in the BIOS

From AHCI to password protection and disable anti-theft, secure boot… I think I changed every option possible (related to SSD) in the BIOS and reverted back to default without my primary SSD showing again as boot option.

1. Clear CMOS

Opening the case and taking out the little battery to clear the CMOS had not effect at all either.

1. boot into Debian rescue mode, boot-repair, chroot session

From a Live session USB tried a few things in rescue mode and even in the Live session used the boot-repair tool and tried to manually fix the EFI/Bootloader in a chrooted environment, because Yes even if I couldn’t boot into my system my data was still there an safe !!

1. Disconnect new SSD, swap bay position.

Even when I removed the new SSD from it’s SATA connection or swaped SATA bay connections, the primary SSD didn’t showed back into the BIOS…

Guess I have to reinstall Debian on my new SSD?

So I gave up on trying to fix the Bootloader and primary SSD and just went for a fresh Debian install on my new SSD.

Nothing uncommon during the installation process except that during the partition all my volume groups and logical volumes from my primary SSD are visible, so I left them alone and created a new VG and LVs. I do as usual a LVM manual partioning with EXT4 filesystem with separate /boot partition, however I forgot to set the ESP partition (was getting a bit late and got a bit on my nerves…). Installation went without issues.

And then It came back…

So booting into my BIOS to see if my new SSD boot position is okay… Ohhhhh and what a surprise to see my primary SSD back as boot choice… however my new SSD isn’t there anymore (expected as I forgot to set an ESP partition… And Bootloader is from my primary SSD).

Booting into my system I’m greeted by the Bootloader? GRUB? With 2 choices

• My old linux OS
• My new linux OS

Some kind of relief and happy moment after 2 days…

Kinda curious what happens If set the /boot/EFI partition on secondary SSD

I got kinda confused on what happened here so to further confuse myself I reformatted and reinstalled Debian on the secondary disk with the correct /boot/EFI partition.

And I got even more confused… The boot priority in BIOS only shows the secondary SSD as boot option…!?

Questions

What happend here?

Why did my primary SSD (which had a proper Bootloader and clean system) disappeared as boot option in the BIOS as soon as I installed a new blank SSD and didn’t came back even when the new one was unplugged from SATA?

Why does my BIOS only shows 1 disk as possible boot device when both have proper Bootloader and system?

Does 1 external Bootloader suffice to make both system work?!

Not sure about the last qusstion… so maybe I’m looking more a less to sharpen my understanding of a Bootloader/EFI/UEFI/GRUB… And any hint to a good resource, book, eBook to get a better understanding is really appreciated :)

I know those are a lot of words (and I said I will keep it short…) but I think the context is important here, and I’m not able to express correctly my issue/thoughts without it.

Thanks in advance for those who beared with me and read the whole text and can hint me to the correct direction to a better understanding on what happened.

Playtron has made some waves in Linux gaming. They have lots of big names in Linux working on the project. Recently they were featured by Framework today in their presentation. However, I think it’s abundantly clear that anyone who cares about FOSS should stay far away from this.

I was intrigued by this as well some months ago. I even ignored when they blatantly lied about Valve/Steam locking down their OS to only play Steam games. So I gave it a try and installed it. On setup they wanted me to agree to a EULA. That was red flag #2. Never seen that before. Then they wanted me to agree to their privacy policy. It is a very typical corporate user-hostile privacy policy. Some highlights

Not many people have heard about secureblue, and I want to spread the word about it. secureblue provides hardened images for Fedora Atomic and CoreOS. It’s an operating system “for those whose first priority is using linux, and second priority is security.”

secureblue provides exploit mitigations and fixes for multiple security holes. This includes the addition of GrapheneOS’s hardened_malloc, their own hardened Chromium-based browser called Trivalent, USBGuard to protect against USB peripheral attacks, and plenty more.

secureblue has definitely matured a lot since I first started using it. Since then, it has become something that could reasonably be used as a daily driver. secureblue recognizes the need for usability alongside security.

If you already have Fedora Atomic (e.g. Secureblue, Kinoite, Sericea, etc.) or CoreOS installed on your system, you can easily rebase to secureblue. The install instructions are really easy to follow, and I had no issues installing it on any of my devices.

I’d love more people to know about secureblue, because it is fantastic if you want a secure desktop OS!

two types of #linux user

A meme showing two opposite experiences using Linux distributions, Arch and Linux Mint. The left panel shows a tired-looking person with dark circles under their eyes, representing an Arch Linux user. The text describes their experience as Arch Linux user: "Turn on computer at 8:45 a.m. Troubleshoot computer. Test. Customize. Tinker. Test a few programs. It's 3 A.M. Turn off computer. Go to sleep." The right panel shows a cheerful person representing a Linux Mint user. Their text reads: "Turn on computer at 8:45 a.m. Check updates in the GUI tool. Work/game/stream content. Turn off computer at 5:05 p.m. Go out to touch grass."
