Upgraded Devuan no longer launches VLC when movie DVD inserted?

Linux Questions - Wed, 02/01/2023 - 19:37
I recently upgraded Devuan from release 3 to release 4 (chimaera, the latest release). If you're unfamiliar, Devuan is basically Debian without systemd.

In releases 1-3, whenever I inserted a video DVD into the optical drive, it automatically started VLC. While I can certainly start VLC from the applications menu manually, it was kind of nice to drop the DVD in the tray and have it start automatically.

Needless to say, now when I drop a DVD in and close the tray, the activity light flashes a few times, but nothing happens in terms of the movie playing. I've looked in control center under preferred applications and VLC is already set as the default multiplayer and video player. None of the things listed under startup applications appears to have anything to do with the optical drive or VLC. I posted a similar query on the VideoLan forum, but the answers I got indicated this didn't have anything to do with the features of VLC.

Happily, I can get movies to play, and better yet, the stability of VLC appears to be much improved.

I bet there's a setting somewhere that links putting a movie DVD in the optical drive with starting VLC, but I'm fresh out of ideas as to where that setting might be. Thanks in advance for any help you can provide.

Any libuvc users around?

Linux Questions - Wed, 02/01/2023 - 19:28
UVC is a standard for doing video over USB, if you look in ports/packages of your distribution you'll probably find it, it's also in Windows and I think Android. There's a FOSS Linux version of course at I've only been using Linux for 25 years or so, this beast is strange. I've had about as much luck reading the headers as the Doxygen documentation, but that's typical. It's mostly for video webcams apparently but it's also possible to get single frames out of it. Most people probably use it for simple webcams, I bought an Svbony SV205 camera for astronomical use, which is what a Chinese company made by mounting a Sony IMX179 sensor in a housing which fits into a telescope eyepiece tube. Normally you use a bigger telescope to gather more light, with this the promise is that you can combine many exposures. Of course the Earth is rotating so you need to call gettimeofday() for each and carefully overlay them, but I haven't gotten that far.

When I run the best program I can come up with it captures several images at different resolutions then crashes, usually a segfault. Trying to run gdb on the core file it seems to be multithreaded and I'm not sure how to debug that. I'm on a Raspberry Pi 3B with 4 cores so there's a thread for each core, but that comes from somewhere in the library, it's nothing I added. After it's done 1 - 20 or so images it crashes, maybe the Pi isn't fast enough, but really it doesn't need to hurry so crashing is silly. An image a minute could work as long as they overlay correctly. I store the images on the sd/hard drive.

Anyway, does anybody know of a forum where such things are commonly discussed? I don't find any mention of uvc here at all.

Should I change my scheduler?

Linux Questions - Wed, 02/01/2023 - 18:58
I just copied 4GB of data from one disk to another.

Whenever I do that, my machine becomes completely unresponsive until the data transfer task is done. I can't Alt+Tab to another application and do something else while the machine is copying.

I don't use any GUI applications for that. It's usually rsync, sometimes gcp.

I've been using Linux for 20 years and it hasn't always been that way. I used to be able to do other things while the machine was copying. Is there anything I can do to change this? Change my scheduler, maybe? I am currently using cfq.

Hello, LQ! routetehpacketz intro post

Linux Questions - Wed, 02/01/2023 - 17:55
Hey everyone,

I actually signed up for last year, but admittedly (and shamefully!) forgot I did. I look forward to becoming further acquainted with the community from this point on :)

I am an IT professional and have been in the field for nearly 16 years. My current role is primarily focused on networking, but I am unabashedly an "IT slut" � meaning I do it all.

I have experience with the more popular distros, and CentOS is usually my go-to. Typical Linux usage for me is deploying/maintaining server applications and Kali for Hack the Box. I do have some experience with KVM, but it is limited.

Slower Download Speed in Linuxmint 20.3 Than Windows or Mac

Linux Questions - Wed, 02/01/2023 - 17:54
Problem: Linuxmint download speed slower than on my 3 other machines
Please see attached files inxi.txt dmesg.txt iwconfig.txt, etc.
I'm using ExpressVPN, and I try to stay current, but as I mention below, I've had this problem for months; I just finally got around to looking for a solution. I use the VPN on all the different OS'
MTU is 1500 if you need to know. None of my browsers give me any errors,
***These dmesg errors just started recently, I've had the slow download speed for months.*** So I include them just to show there's nothing else.

I'm using Linuxmint 20.3 Cinnamon on one machine (tried LM21,and went back); also, I have a Macbook Pro Intel, and two other Windows laptops, one Windows 7, the other Windows 11. I forget the numbers, but will guess between 25-35% slower.
I use the same download helper called DownThemAll, an extension that I add to Firefox, Brave, Waterfox, Librewolf, Vivaldi, and MS Edge. I use Waterfox most of the time (at least for large iso downloads). But when I do large downloads from the same site with the different computers, the Linuxmint does not give me the same speed as measured by the DownloadThemAll (whether the machines are downloading concurrently or not). The Windows machines and the Macbook do pretty similar speeds which are faster than the Linuxmint.

What I've tried:
So I am wondering where to look. I've tried searching for various themes of "different download speeds windows linux", etc., and "slow download speed linux" but nothing seems to be the answer. I've looked for setting the MTU, but with several tests of ping, I don't see a problem. I have tried a Code: ping -s 4096 (yes I gave it a couple of addresses), and got no errors. Me thinkest I doth bark up the wrong tree. So I'm guessing it's something else. I wondered if it was some setting of my wlan0 that I would have to change in ethtool (which I couldn't figure out how to manipulate or which part of the nic to adjust, anyway). So am I even in the right ball park? What should I be looking for? Thanks.

You prefer Kubuntu tp Lubuntu versions of Ubuntu?

Linux Questions - Wed, 02/01/2023 - 17:33
Having used Linux since my first Red Hat versions, I have grown to love Kubuntu due to its proximity to Windows OS. Having converted Windows XP desktops to it, gifted users don't realize they are using a different operating system.

"Live" USBs not working

Linux Questions - Wed, 02/01/2023 - 16:16
I have been trying to use a live USB without success. My latest Live USB has Lubuntu. Nothing happens, even when I tried earlier USBs of other Ubuntu versions. I did the SHA256 test and the downloaded version is fine. I used Startup Disk Creator. Is there something I am doing wrong or not doing?

Thanks for any advice!

pet theory: IPV6 not worth enabling @HOME

Linux Questions - Wed, 02/01/2023 - 14:51
So I had an ipv4 "super server" years ago but couldn't afford the bills (my cable company port blocked it - wanted money to re-enable ports).

I recently booted this IPV4 it on a newish high speed cable-modem, used it lazily not upgrading to ipv6 a while. i'm lazy - did it 2 yrs before considering switching to ipv6.

I have (resources) on enabling IPV6, but they aren't well secure, poor really. For example: i have no kernel patch for "forcing kernel to ignore/deny ipv6 route changes" (route changes are absolutely not secure - they are terribly in-secure).

I find ipv4-to-ipv6 works VERY efficiently - xfer rate is good.

* so my modem does all the work and is fast.

* my @HOME network is secure in itself with IPV4 (ipv4 is far simpler to set up and mine is already set up!) My LAN does not leak on IPV6 because IPV4 is better than IPV6 in that respect.

QUESTION: Why should I use IPV6 @HOME. Sure in a data center I must use it to conserve ip's. But what good is it @HOME?

please comment

Time to GET real serious dedicating a full on PC build to LINUX

Linux Questions - Wed, 02/01/2023 - 14:13
I been tossing around for years but never actually done it.
I use linux in a VMworld daily (mostly LINUX MINT, to me i dont need all the eye candy, i just like the fact it works when i need it to) i have a laptop i do all my banking on with linux .. but NO real desktop to say.. (i use that laptop for trying various distros)

so I am really considering this for a dedicated FULL LINUX PC.. semi older build i have laying around. This will be mostly used for internet/banking/some videos/ some kind of NAS/ftp server perhaps(yes i still enjoy a good FTP server) a place to backup my windows machines.
perhaps i will reverse this process and vm windows onto this machine.
I want to start trying to use this as a daily driver and leave my winblows machine for gaming only.. as really thats all its good for.. well that and converting my old DVDs to ISOs or MPG files , but i should be able to do that with linux.

AMD FX8350
Gigabyte FX990-UD5 series board.
nvidia GTS 8800 (not looking to play heavy games)
5x 1 TB HDDs

any thoughts? Im not looking to win any races. this is a machine i have laying around that is doing nothing I upgraded from that to a Ryzen system for my gaming rig so this still has windows but i want to scrap that for a dedicated workstation
