Linux

Is it possible to use a reverse ssh tunnel to force all network connection on the remote host through the local host.

Essentially:

local -> ssh -> remote remote web request -> ssh tunnel -> local -> internet

I want the remote to make connections through the locals VPN without having to authenticate on the remote as well

Hopefully this makes sense

Hey, I hope someone can help me.

Problem:

When I wake my PC from suspend, my monitor is always set down to 30% brightness for some reason.

These are the brightness settings of the monitor itself, which can only be accessed via the monitor settings using the buttons on the monitor. I do not mean the brightness settings of my desktop environment. These are still set to 100%, even though the monitor is darker.

The problem also arises in a second case. When I lower the brightness in the brightness control of my DE, my monitor brightness is also lowered in the monitor settings down to 30% again. I can then no longer increase the brightness in the DE settings, because 100% in the DE now equals 30% in the monitor. So if I set the brightness to 50% in the DE for example, this is 50% of the 30% set in the monitor. So actually only 15% in real terms

I hope I was able to explain the problem clearly. Please ask if you don't understand something. It's really annoying because I need to turn up my screen brightness with the Buttons on the Monitor every single time I wake up my PC.

Technical data:

• Nobara Linux 41 (Based on Fedora)
• KDE Plasma 6.3.3
• Wayland
• Desktop PC. So a external monitor. Not a laptop monitor.
• I have a 2nd monitor on which this does not happen.

Seeing that DVD are slowly going end-of-live and that you can't buy a lot of my childhood favorites in german anymore and streams are compressed-to-death (and DRMed), i had a streak of preservia. Which is why i rip a bunch of discs from the library on Linux (yes, legally not ok, but morally just ease of access, i wouldn't sell them). Since it's only to watch them when nostalgia hits, i want them in a ready-to-watch format, chose AV1 webm for small size. My burner is LibreDrive-ok ootb, meaning makemkv goes automatically in that mode.

I have the discs for a limited time, so i used to use dvdbackup for DVD and later feed the folder to handbrake for conversion. Now i got a bunch of blu-ray:

• ripping one takes even longer; whole 25 hours; i don't have the time for the whole LotR series with bonus disks.
• makemkvcon backup needs only about 2 hours per disk, but the resulting folder is 80 GB big; i have only about 250 GB free space ** and the makemkv backup somehow has no audio streams, while handbrake does

While i write this, handbrake is loading the chapters (that alone needs more than 1 hour for blu-ray); i'm trying if a lossless FFV1 mkv conversion (for later re-conversion) takes less long.

Now:

• Any better approach?
• Any way to fix makemkv having no audio? (i could juggle with external disks) I think i have all libraries and the KEYDB.cfg.

Edit: nope, handbrake suddenly has unable to decrypt unit (AACS)

Qt 6.9 is here! This release brings exciting innovations, enhanced graphics performance, and new platform capabilities to help you build exceptional applications.

Highlighted improvements in Qt 6.9 include:

• Qt Graphs: Interactive 2D panning, zooming, and dynamic 3D graph injection. Printing support now available!
• Qt Quick: GPU-accelerated SVG animations and Variable Rate Shading for improved graphics performance.
• Qt Quick Controls: New context menu support enhances desktop integration and user experience.
• XR Enhancements: Haptic feedback added for creating richter immersive virtual interactions.

There has been discussions with-in the development circles regarding a potential integration of Web3 functionalities into the mainline kernel. Exploring the feasibility of incorporating features like decentralised application (dApp) support and smart contract execution directly into the kernel.

Early proposals suggest leveraging the NPUs in new processor families for secure on chain data validation within the kernel space. This means better fraud protection by validating signatures while booting up using the zk-SNARK cryptographic proof.

The developers at Linux Fundaytion notes that this plan requires extensive re-architecture of the codebase. They say that after this, Linux would only run supported systems with dedicated NPU and will simply refuse to boot on other systems, making a significant breakthrough in system security.

The timeline for the proposed changes have already been laid out. With chip manufactures already including dedicated NPUs, developers now have more freedom than ever. Linux communities have always welcomed Web3 technologies like NFT, dApp games etc. and with the kernel integration, Linux will be making a huge leap into the future. One developer put it aptly, "Imagine running my own ETH node directly within Linux kernel."

I have an x220, yes it is old but I prefer the keyboard and the repairability. Anyway, it has 1 x msata SSD (2TB Orico) and 1 x 2.5 inch SSD (2TB Samsung).

What I want:

• to take advantage of 2 drives.
• no windows. I go full Linux now.
• some forms of backup if system fails.

What I managed to do:

• /, swap and all system directories on the msata

• /home is dedicated to the entire 2.5 ssd.

• fully encrypted. I.e the msata has a LUKS partition that mounts /, swap and others. The 2.5 inch also has a LUKS partiton for /home. My /home is on its own, so if system fails or I need to distro hop, I can keep all of my data.

System runs fine but is this a good idea in the long run?

Should I have it the other way? Root and swap and systems on faster 2.5inch SSD. Home in the smaller msata?

What about everything on the faster 2.5 drive, then use the slower msata for backups? Since I have 2TB, I'm thinking partition the msata into 2 so I can do: Timeshift backup on one, and Borg backup for my personal files on the other?

So I recently built a new computer to replace my 7 year old one but I have noticed a strange problem with it.

When I boot up the computer and use it as normal it sits around 8-10 GiB of ram in use plus about another 9 GiB committed.

But when I suspend the computer then un-suspend it later the in use ram starts creeping up even if I have less running than I did when I originally booted the computer.

Last time this happened it went from 10 GiB all the way up to about 43 GiB in the space of a few hours.

If I reboot then things go back to normal behavior.

Anyone have any ideas about what I could look for to fix it?

I discovered GoboLinux not long ago and was disappointed to see it was no longer being maintained. It's exciting to see some folks are picking it back up again.

i want to test debian trixie (13) so i can report bugs and troubleshoot before the release later this year. i thought about simply installing trixie alongside my current bookworm installation, but that won't be my scenario when the time comes, since i've been updating my system instead of reinstalling it since debian jessie (8) and this time it won't be different. how can i clone my current system so i can simulate an update to trixie? do i simply create a new partition and copy my files over, then chroot to it and install grub?

Couldn't find a dedicated community for distro recommendations, I hope it's ok to ask here.

A couple of years ago my wife and I built a computer and gave it to a friend's kid. We put ElementaryOS on it since that seemed pretty fool-proof, but it appears to require a re-install to upgrade major versions so it has been stuck with an old glibc and because of that he can't play Factorio.

For his 13:th birthday we bought him a SSD so it would be a good time to reinstall Linux, but is there perhaps some better choice than ElementaryOS? They live quite far away so I can't easily pop over to fix his computer if something breaks, we don't spend enough time there for me to teach him to fix things himself, and he doesn't seem very interested in learning how computers/operatings systems work either.

• Hardware: Some old Intel CPU with 8GB DDR3 and a GTX1080
• Usage: Gaming through Steam+Proton, Lutris and browsing.
• Requirements: Games work, OS never breaks on updates. Doesn't need to be "kid proof", I don't think he touches any stuff he doesn't know what it does.

SOLVED - "Allow screen tearing" was ON and caused this issue.

I have some constant stuttering on my current setup. Every 4-5 seconds, almost like a hiccup, I drop about 100 ms worth of frames.

This has been persistent through several GPU driver updates and I'm tired of trying to troubleshoot it. I don't know what the exact cause is. Any ideas?

Also, related note, how easy is it to migrate from one distro to another? I am thinking about trying something else - maybe base Fedora or Arch - to hopefully have better performance.

The diversity of Linux distributions is one of its strengths, but it can also be challenging for app and game development. Where do we need more standards? For example, package management, graphics APIs, or other aspects of the ecosystem? Would such increased standards encourage broader adoption of the Linux ecosystem by developers?

Does anyone know how I can troubleshoot this?

I want my laptop display to not dim when the device is inactive. However, when I go into GNOME's settings and uncheck the option under Power Saving my choice is disregarded; the screen still dims. Is it being overridden somewhere?

Response to a recent claim that Ctrl+D in the terminal is like pressing Enter. It kind of is but it’s also misleading to say so without further explanation.

Hi all!

I recently installed Tuxedo OS with KDE and Wayland. I'm fairly new to Linux and, so far, the distro is great. With one caveat.

As far as power options go, everything works fine EXCEPT for Sleep. I can put the PC to sleep, but when I wake it up, I land on the login screen wallpaper with the login/password fields barely visible, as if frozen around the second frame of a fade-in animation.

Nothing works. The mouse cursor doesn't move, the keyboard doesn't do anything. The only way out of this state is to hold the power button until the PC shuts down and then turn it back on again.

I did some digging, but couldn't find a solution. Some threads mentioned modifying something in systemd, but those were from years ago, so I didn't want to risk that.

One fairly recent thread had a proposed solution of adding "mem_sleep_default=deep" to GRUB_CMDLINE_LINUX_DEFAULT in /etc/default/grub.

That didn't work for me, though.

I'd love to fix this, but I'm out of ideas. Any help welcome!

EDIT

Forgot it might be a driver issue, people were complaining about Nvidia gear!

I currently don't have a dedicated GPU. I only have Ryzen 7 7800X3D running on MSI B650 Gaming Plus WIFI ATX AM5 MoBo.
