I used s3sync in the past instead of rsync/fuse. It's not maintained now but it still works like a champ.

If I type it in by hand it works fine. So I think it has to do with the fact that I'm cutting+pasting from a web page.

Paste it into Notepad first, then copy it again. It looks like the terminal is pasting it as encoded text.

You can mount your file systems with the discard option. If you're using LVM as well you may have to update your lvm.conf file to allow discards to be passed to the underlying physical devices as well.

The frustrating thing about using the shell is copy-pasting commands or code in.. if it's anything longer than 100 chars, it gets really frustrating to get stuff across from webpages or code snippets etc. That's why I prefer VNC or a server GUI to be able to bulk-add text.. how do you guys get around that? Do you just add the code to a file on your local machine and transfer from there, or what?

What are you using to paste things? I never run not those problems with Putty.

Debian is easily the most boring Linux distro by a long shot but I don't think that's a bad thing. Debian Stable is actually super stable. The only problems I've ever had with it are when I've deliberately went out of my way to do something boneheaded, like back when I experimented with network mounting /usr.

I guess if you're actually going to be playing games you want to use backports or a distro that is more bleeding edge though.

I've been using Steam on an nvidia card (w/ binary drivers) on Debian Stable for a while now, works great! You'll want to use the Flatpak version of Steam but I've run into basically no issues including with performance monsters like Cyberpunk. I think the only backport package I have is btop cause it looks cool.

The 4090 doesn't have nvlink so if your ML tasks can be split memory-wise between a 4090 and 3090 in batches then that combo will be great; if you rely on the combined GPU memory of two 3090s though then you'll be out of luck.

Does anybody actually daily drive vanilla Gnome 3 besides the people who actively develop on the project? Just seems like a huge pile of bad design decisions

I wasn't sure what GUI I had previously installed in 2020 and accidentally installed Gnome 3 instead of KDE, but it was glaringly obvious when the start button went missing, as did the minimize/maximize buttons

I guess Cinnamon and Mint are the successors to Gnome 2

I just tried the latest Debian package of Gnome on a throwaway VM and... they literally removed the feature where the taskbar of the desktop shows multiple apps. Like, you have to now click Activities then click the window you want to switch to if you're using maximized or non-overlapping apps. What the gently caress?

And not only that, to get multiple running apps showing they walk you through installing a browser plugin that can in turn install Gnome shell extensions, goddamn. I feel like I'm being trolled.

Edit:

Look at all the empty space that could still be showing the running apps LOL.

Or press the windows/meta key. IIRC you can also start typing in that view to search for applications you want to launch, so the "win, start typing" muscle memory from windows works (albeit with very different visuals). It's kind of nice when you get used to it.

Yeah I know there's workarounds but I'm using i3 and just wanted a throwaway VM and didn't expect you know, the basic tenet of a taskbar to be different after a couple decades. Nested meta keys also aren't super fun so back to xfce4 for this task. It's still strange to me the most conservative DE is still so quick to drop basic functions like this.

The two main files to look at when troubleshooting VNC server issues are "xstartup" and the log file in the "~/.vnc" directory. xstartup has the commands to start when VNC starts, my XFCE4 one looks like this:

code:

xrdb "$HOME/.Xresources"
xsetroot -solid grey
export GDK_SCALE=1
dbus-launch xfce4-session

Can you paste yours, and take a look at the log file to see what failed?

Since you're mentioning it I may as well ask, is there a way in nixos using that configuration to specify versions or have some kind of lock file? I always see these configuration examples but a new machine built would have all different versions of those things and I'd like to have one captured snapshot (like a Gemfile.lock or whatever JS uses now)

Interesting! I do a bunch of contract work and keep each company's data in a different VM and it'd be super nice to build the VMs using this and be able to rollback whenever nvidia fucks up their drivers around ML stuff. This looks great, thanks!

Eh it is what it is. Right now under Debian things are pretty rock solid day to day on the CUDA side of things but the newer Windows drivers added this insane poo poo where they overflow GPU memory into system memory and I'm trying to get ahead of that appearing in the Linux driver. It's workaroundable but also, jesus christ the whole reason for using a GPU is because it's 1000x faster than the CPU, what an insane feature.

I'd love to use AMD or anything else if they stepped up their game but it's loving laughable at this point.

VVV very on-topic, goddamn

rsync doesn't have any caching but it definitely sounds like there is something weird with your case as it's quite a common usage.

I believe they're doing rsync on two local filesystems where checksumming will not happen at all in the first place.

Less Fat Luke: May 23, 2003; Exciting Lemon

That's interesting, TIL. And yeah as far as I know there's no delta transfers for local rsync, it should always do the full file.

I wonder if it could be something as simple as the Windows partition having the timestamps stored in the wrong timezone or something (related to Linux having the hardware clock in UTC versus Windows) but I have no idea at this point, sorry. Plus you said you've manually checked the timestamps in Linux so that should rule that out.

Any Synergy users here? First day of work today and somehow it was fully broken on my main machine (Fedora 39). Luckily I had the previous version's RPM lying around but I spent a long time today trying to figure out the issue, never did. Broken version is 3.0.78.1, working version 3.0.77.2. The only clues I found were references to gdm. The packages from Symless say they're for Fedora 38, did something change around gdm for 39?

I can't help with your specific problem but after a lot of bullshit with Synergy I switched to Input Leap and it's been working solid for like a year now between my Windows and Linux PCs.

Yeah same under Debian primarily; I need to use it for CUDA stuff but I also play a lot of games with the binary drivers on Debian, no real issues other than the usual Linux bullshit occasionally. That being said I would buy anything else if I didn't need it for work since their GPUs are so goddamned expensive.

I can suspend without a loving problem on Kubuntu. It's not my GPU at all, it's whatever was going on with EOS that didn't want to play along.

It boots up slower than EOS does, apt feels slower and it seems like I'll need to use whatever snaps are to get certain apps working, but it works for now. I'll take it.

I spent all day trying to figure out why my Debian install (and various live CDs) would *not* initialize a new AMD GPU correctly - installing backport kernels, firmware from the kernel git, custom building a kernel, a million different things. Eventually I found a setting in my BIOS named "BME DMA Mitigation" that immediately made it work even with the stock Debian stable kernel. Goddamnit computers.

Hm kinda seems like rasdaemon itself is crashing using it's own database; I would probably stop the daemon (systemctl stop rasdaemon) and clear out the db; on Debian it's /var/lib/rasdaemon/ras-mc_event.db and then start it again (systemctl start rasdaemon).

Also this kernel version chat made me remember to try a newer kernel on Debian 12 to get AMD p_states going so I went to 6.8.1 and it literally dropped my wall-power usage in half when idling - cores drop to 400mhz now instead of 1800mhz. Worked great for a few hours til I tried to launch a Steam game and of course ZFS is currently broken with that kernel, lol.

Edit: Also cool graph porn:

Double-edit: Turns out the "stable" 6.7.10 kernel is what I wanted, AMD p-states and a functional copy_file_range for ZFS.
