Can't view videos in firefox: VA-API test failed
Whenever I try to view videos in Firefox in my trusty Thinkpad T61, Firefox just eats up the CPU but doesn't actually show the video. At startup I get the following message: [GFX1-]: vaapitest: VA-API test failed: failed to initialise VAAPI connection. So, IIUC the problem is that the hardware video decoder drivers aren't found for some reason. I checked my VA-related packages and they seem to be installed: # aptitude search '\' | grep '^i' i A i965-va-driver - VAAPI driver for Intel G45 & HD Graphics family i intel-media-va-driver - VAAPI driver for the Intel GEN8+ Graphics family i A libvdpau-va-gl1 - VDPAU driver with OpenGL/VAAPI backend i A mesa-va-drivers - Mesa VA-API video acceleration drivers i va-driver-all - API de Video Acceleration (VA) – métapaquet de pilotes i A vdpau-va-driver - VDPAU-based backend for VA API # I tried to install `intel-media-va-driver-non-free` to see if that's the problem, but it did not make any difference. I understand that my machine is fairly old, but it used to be able to play youtube videos just fine without eating all my CPU time (i.e. using hardware video decoding from its GM965/GL960 Intel integrated graphcs). Any idea what might be going on? Any hint how I could diagnose the problem? Stefan
Re: Seeking a Terminal Emulator on Debian for "Passthrough"Printing
Hello, On my technical side, I don't have insight into the contractual aspect or the costs involved. I'm not involved in the bidding and proposal writing phases either. My role comes into play after project maanger send me companies solutions to evaluate them from a purely technical and security standpoint. If the solutions pass our initial technical evaluation (performed by the systems teams), they are then passed on to more specialized functional teams for further testing. I wasn't familiar with the English acronym TANSTAAFL (There ain't no such thing as a free lunch), but I completely agree with it. My internal technical specification is to have an equivalent to the commercial product I have on my Wyse PC for testing. The decision to promote Putty was mine as a Linux enthusiast and advocate for open-source software. It performed well in testing, except for the passthrough printing aspect. The only cost I'm aware of is that of a proprietary product I mentioned earlier, which is available on their website: "AnzioWin starts at $150.00* per PC with quantity discounts beginning at 10 copies. Anzio Lite starts at $40.00* per PC with quantity discounts beginning with a license for 10 PCs." So, if we consider the cost of the more expensive version and assume we have 1000 PCs, it would range from $150,000 to $75,000 without any discounts. I won't disclose the exact number of our PCs, but let's say it falls within the range of 500 to 1000. I assume that with the simple cost of software plus the undisclosed maintenance cost paid annually, we could allocate a budget for open-source development that would benefit our company and, subsequently, the community, especially if the open-source product becomes part of the official product branch with included maintenance. What I can say is that I have management's approval for my interactions with the community and exploring potential open-source alternatives. However, there are no guarantees at this point, as I haven't yet produced concrete results in terms of an open-source alternative or engaged with the community for further development, budget allocation, and associated assurances. My approach might be naive or clumsy because I'm not familiar with the customs and practices in this business field. For the time being, our project management team prefers that the system team engages with the community to find something and intervenes later on in the negotiation and commercial aspects.

I've tried to be as precise as I can in the technical description. I understand I'm seeking help, but it's challenging for me to provide specific product names and details without violating the security guidelines I've agreed to in this project, which is critical for our company. I have previously mentioned that this is a Point of Sale (POS) system, consisting of the workstation (Wyse-type) that includes the terminal emulator and the receipt printer. This setup is used in the retail sector, primarily for sales transactions. I cannot disclose the names of commercial products in use because we are simultaneously evaluating various proprietary products in a competitive pre-sales phase. My role is strictly technical, focused on providing unbiased, pragmatic, and fact-based assessments of solutions, whether they are proprietary or open source. I always provide detailed arguments and references whenever possible. I must avoid any potential legal issues that could arise from disclosing sensitive information to any of the product vendors involved in the project. Additionally, I don't use the application myself, and I'm not familiar with its functional aspects. My knowledge is limited to the technical aspects of how things work, more like a black-box perspective. I can, for example, mention that this guide explaining passthrough mode (https://www.anzio.com/resources/guide-anzios-passthrough-printing) is a proprietary product that could potentially meet our requirements. I can cite it because, as of now, the project team hasn't initiated any commercial contact with this vendor during the pre-sales phase. However, the technical principles are well described in this resource: https://www.anzio.com/resources/printing-anzio in the Passthrough Printing + Aux Printing section, along with this additional resource: https://www.anzio.com/resources/using-aux-devices-anzio. The current emulator comes bundled with the Wyse-type workstation equipment; we don't have access to this software independently. From a practical standpoint, when it comes to printing, we simply select the Passthrough Printing option and choose the COM port. That's all there is to it, and it works this way. It's almost the same as in PuTTY, except here, we can choose a hardware port instead of a virtual printer. Regards, Thierry

Re: Seeking a Terminal Emulator on Debian for "Passthrough"Printing
Hello, >> On the Linux server, are there multiple users logging into this server via >> ssh and each of them needs to print to a local printer in the way you >> mention? Yes, there are indeed multiple users logging into the Linux server via SSH and each of them needs to print to a local printer specific to their Point of Sale (POS) activity. This is essential because it involves a POS station and a printer specifically designated for this business activity. >> Would one normally attach a printer physically to the server and your >> software talk directly to this locally attached device on the server? I am >> curious how, if you have multiple users logging in, the software would know >> which ssh session to use to communicate with the local physical printer. Indeed, it is possible to physically connect a printer to the server and the software could communicate directly with this device through a print spooler system. However, in the context of our Point of Sale (POS) environment, this approach doesn't make sense. The printer needs to be dedicated to the POS station, ensuring that the staff using the PC is as close as possible to our customers and that the printing occurs directly in front of them quickly and seamlessly. In the case of SSH sessions, each user connects to the server with their individual session streams. The printing flow is, therefore, directed through this session in a straightforward and secure manner (which is the essence of printing in passthrough mode). >> When you say ‘serial port’ as in com1:, are you referring to an old RS422 or >> RS232 serial port? Or is the device connected to a USB and has an >> association with com1 on the windows side? When I mention a "serial port" like com1:, I am indeed referring to a traditional RS422 or RS232 serial port. If the device is connected via USB and is associated with a virtual com1 port on the Windows side, it doesn't require any software modifications to handle printing in passthrough mode. From the perspective of the proprietary terminal emulator, the data flow goes through a COM port, whether it's physical or virtual. >> I recommend that you do not try and modify PuTTY or KiTTY or any of the ssh >> terminals. This will be hard to support and you may cause a security >> nightmare. We absolutely refrain from attempting to modify software such as PuTTY, KiTTY, or SSH terminal emulators ourselves. This is because it can be challenging to implement and may pose security risks. Therefore, we are actively seeking to engage with the teams behind these projects to explore potential solutions that align with our needs or we are considering proprietary alternatives >> A possible solution is to run some small glue program on both sides of the >> connection which uses a port forward tunnel.

I cannot say if this solution would be viable when dealing with multiple users simultaneously. I don't have the flexibility to alter the behavior of the application, and this introduces constraints that I must consider when searching for an open-source solution to meet my requirements. Of course, if I opt for proprietary solutions, I have a clear path to solving my problem. >> If you have multiple people logging into the server, you will need to find a >> way to multiply the printer port on the server.

Instead, the choice in this case would be to continue investing in a proprietary terminal solution, despite its cost, as it would provide more reassurance to the project team than the long-term expenses associated with maintaining this type of Windows development.

Don't get me wrong: I'm not criticising your decision process. I'm long enough in this business to know that technical processes are evolutory. You change a few things and keep most of the rest (because that "rest" is so overwhelmingly complex and huge that you have to). Which parts to keep and which to change is a tough decision which IMO has to be taken by the people involved. Things like "disruption" are, in my view,just empty marketing terms :-) So no, I don't believe your choice is misguided. Who am I to. I still believe you'll have an easier (technical) life if you separate the terminal and the "dispatching" process (now talking about UNIX processes) -- the latter might be minicom or something in its class, or something written in C, Python or Perl or whatever your folks are comfortable with. The fact that both have a separate address space is hidden in the "Linux box", which may well be a Raspi or something similar. But I'm aware that I might well be wrong: if one of us is wrong, then it's me :-) Cheers -- t signature.asc Description: PGP signature

We already utilize the TCP protocol for communication over Ethernet, as the transparent printing flow is encapsulated within the encrypted SSH stream.

The use of a terminal emulator in passthrough mode is tied to our existing infrastructure and the way our application was originally designed. Within the scope of the ongoing project, which involves migrating our application from Unix to Linux, it is not within the migration's scope to alter this particular aspect, as it is both critical and sensitive. While I have some leeway to propose technical enhancements and changes, this specific area is off-limits due to its significant impact on a crucial functional aspect from both a business perspective and certain certification standards under which our POS system is certified. >> By the way -- back then (TM), when terminals were real things, it was >> not unheard of that they came with an attached printer and some bar >> code scannery -- all handily multiplexed over the RS-232 (or something >> more monstruous), orchestrated via intricate escapery.

Regarding the use of Putty, it appears that in some cases, it can partially meet our needs by allowing interactions such as printing tickets and opening the cash drawer. However, i also mentioned that some other operations do not work. It is important to note that Putty is primarily designed as a terminal emulator and may not be equipped to meet all the specific requirements of our retail application. As for the evolution of Putty, it is understandable that the developer has not responded to our contact attempts, and we respect their decision to maintain the software according to their own criteria. I also pointed out that we have proprietary emulator solutions that come with integrated hardware offerings, such as Wyse-type client terminals or Android tablets. These solutions meet our needs and provide the necessary services at a given cost. I just to emphasize that the diversity of options, whether open source or proprietary, is a wealth, as it allows each company to find the solution that best suits its needs. Ultimately, our goal is to find the best solution for our retail application, taking into account hardware compatibility, required features, and associated costs. While we are open to exploring open-source solutions if they can meet our needs, we also value the reliability and support that proprietary solutions can provide. We will continue to evaluate all available options, ensuring that we choose the approach that best aligns with our business requirements and technical considerations. Regards, Thierry

Attempting to diagnose issues without all the facts is an exercise in

Putting a sector size 512/512 disk and a sector size 512/4096 disk into
the same mirror is unconventional. I suppose there are kernel
developers who could definitively explain the consequences, but I am not
one of them. The KISS solution is to use matching disks in RAID.

Yes, the challenge here is ideally to migrate the Windows-based workstation to Linux, provided that we have the necessary open-source emulator.

You suggest an interesting alternative by using the desktop sharing feature available with GNOME to interact with the application remotely. I was not aware of this particular use of the GNOME feature; I primarily knew it for remote control and screen sharing purposes. At this stage, I am not yet familiar enough with GNOME to provide a comprehensive opinion on this approach. However, I want to emphasize that within the scope of the mission I have been entrusted with, I do not have the authority to modify the server application's functionalities. I am subject to the constraints and decisions of the project team. Therefore, implementing this suggestion goes beyond the boundaries of my current responsibilities. >> In the original (proprietary) application, the dispatching functionality > > Dispatching functionality? > >> is integrated in the terminal emulator, so it is understandable that >> pheoebus phoebus wants to keep that structure in the replacement. In this project to migrate the application server from Unix to Linux, the primary objective was to maintain the stability and functionality of the server component, while the client side (the terminal) underwent an evaluation to explore open-source alternatives to the proprietary terminal emulator solution, all while preserving the existing functionality. > Well, I'd have to be quit a bit older to have experienced "real" > terminals like that.

This application does not run on a physical "real terminal" but on a terminal emulator, which is software running on a Windows-based workstation (Wyse). Currently, there are various hardware options available for this, including proprietary solutions with newer versions of Wyse and proprietary terminal emulators, as well as Android-based devices that can fulfill the task with proprietary emulators. However, as someone working with Linux and for whom open source and freedom have significance in my profession, I proposed to explore if there might be open-source solutions that can meet this requirement. If there are none available at this time, then so be it, but at least considering this option in our evaluation is an important step for us when it's feasible. Regards, Thierry

Re: Seeking a Terminal Emulator on Debian for "Passthrough" Printing
Hello, > Ok, and what's the problem? That the server wants to print to the > printer? That the application sends data to the "screen" (a terminal > emulator) instead of sending it to the printer? That it is necessary > to see the printer data displayed in a terminal emulator? The problem here revolves around the interaction between the terminal emulator, the application, and the printing process. The terminal emulator has a "printing passthrough" function, which means that depending on the user's interactions with the application, data can be displayed on the screen and, at times, passed through the terminal's passthrough mode to be printed on the physical printer. So, to address your questions specifically: 1. The server itself doesn't initiate printing; instead, it's the user on the workstation with the terminal emulator who wishes to print to their local printer. The application running on the server sends data to the user's screen (terminal emulator) and, when requested by the user, can be sent to the user's local physical printer connected to their workstation. 2. The application may send data to both the screen and the printer, depending on the specific user interactions and transaction requirements. The screen serves as a visual interface for the user, while the printer captures some of the data for hardcopy records. 3. It's necessary to have the option to selectively send certain data to the physical printer from the terminal emulator based on the user's choice, as it provides real-time feedback and visibility for the user during interactions with the application. However, not all data displayed on the screen needs to be sent to the printer, as it may include additional information or layout formatting relevant to the current screen content or user interactions. The display on the screen and the printing on the printer are designed to complement each other based on the specific transactional needs and the user's preferences. Regards, Thierry

I believe I have addressed these questions as accurately and honestly as possible in my previous response to Greg, while also incorporating the information we discussed earlier. Regards, Thierry I might point out in all this hand waving, that no one puts a contract out for bid, without specifying the performance required to do the job, which we aren't privileged to see. A description of what it must do, should not be a copyright probem as its is part and parcel of the "clean room" description the coders work from. That and what you might be willing to pay a competent programmer to do might sweeten the project enough for a free software developer to do. These people here are doing it to aid the free software environment, doing it for our thanks, but they like to be able to eat and pay the rent. like TANSTAAFL, it is not optional. The OP's choice is not to do that specification. If that spec is forthcoming, and doable with the tools we have you may pique someones interest. They in turn may contact you privately with an estimate/offer. But w/o that spec, so the coder knows for sure what it must do, circular without any solution will be this thread. We may even already have a POS system you could use. I know for a fact one of the local grocery stores here in this village of around 6000 is running something on linux in the checkout lanes, I saw it boot up after a power failure before the actual app was auto-started. What that app was, no one had been instructed as it was totally auto starting. Typical of the checkout lanes I suspect. FWIW that coder isn't me, my coding heyday was in the later 70's thru about 2002. Now I'm 89 and retired for 22 years, diabetic for 40 years, chest full of hardware, running on what some might call borrowed time.

Explain, please. Your Subject: header says "su su- sudo dont work". What does this MEAN? Please show us your attempts to USE each of these commands, and the results that you got. This means, run the commands in a terminal window, and then PASTE the contents of that terminal window into the body of your next email. Show us the shell prompt, the command as you typed it, and the full output. In other words, show us WHAT IS WRONG, or at least what appears wrong. In addition, please give basic background information -- what version of Debian you are running, what desktop environment if any, how you logged in (*especially* if it isn't just a "standard graphical login for your desktop environment"), and anything else you can think of that might be relevant. How does "rescue mode" factor into the problem? When you installed Debian, did you give a root password, or did you leave it blank? Finally, it would be helpful for you to run the "id" command (with no arguments), in the same terminal session as your failed su or sudo command(s), and include that command and its output in your paste.

Please tell us: exactly what rescue mode you were using exactly what the prompt was exactly what you typed exactly what the response was exactly what you want to have happen Unless you tell us all of these things in one email message, it will not be a good idea for any of us to try to help you.

It might be sensible to screenshot the setup you like. If you have similar problems in future it would help enormously to be able to show people the layout you like vv the one you get immediately after a reinstall. And, of course, write notes to yourself for EVERY change like this, so you can remember how you did it. -- Jeremy Nicoll - my opinions are my own.

Disk corruption and performance issue.
This is rather long - so if you're replying to just one bit, please consider trimming the parts that you're not responding to to make everybody's life a little bit better! Some time ago I wrote about a data corruption issue. I've still not managed to track it down but I have two new datapoints one (inspired but a recent thread) and I'm hoping someone will have ideas how I should move forward. By avoiding heavy disk load (and important tasks/jobs!) on the problem machine I've had no more data corruption. There are no errors/warnings anywhere. A part of me is suspecting a faulty SSD! I have new disks on order so I can replace the existing disks soon if that's what it will need to fix this. Inspired from the recent thread: On the server that has no issues: sda: Sector size (logical/physical): 512 bytes / 512 bytes sdb: Sector size (logical/physical): 512 bytes / 512 bytes These are then gpt partitioned, a small BIOS boot and EFI partition and then a big "Linux filesystem" partition that is part of a mdadm raid md0 : active raid1 sda3[3] sdb3[2] On the server that has performance issues and I get occasional data corruption (both reading and writing) under heavy (disk) load: sda: Sector size (logical/physical): 512 bytes / 512 bytes sdb: Sector size (logical/physical): 512 bytes / 4096 bytes I'm wondering if that physical sector size is the issue. All the partitions start on a 4k boundary but the big partition is not an exact multiple of 4k. Inside the raid is a LVM PV so I think everything is 4K aligned anyway except the filesystems themselves and the "heavy load" filesystem that triggered the issue uses 4k blocks. But I don't know if something somewhere has "padding" so that the actual data doesn't actually start on a 4k boundary on the disk. There are a LOT of partitions and filesystems in a complicated layered LVM setup so it will be easier for me to check with instructions than to try to provide the data for someone else to check - if someone can give me instructions to work out exactly where the data ends up on the disk. (all partitions are formatted with ext3) The remaining setup is identical The new disks are the same make and model as sdb in this server - I hope that's not a problem! The second datapoint. My VMs all use iscsi to provide their disk. Normally the vm runs on the same server as the iscsi target but today I did a kernel upgrade on a pair of vms (the one on the "problem" machine took about twice as long) and then "cross booted" them and purged the old kernel. I actually took timings here: Booted on the problem machine but physical disk still on the OK machine: real0m35.731s user0m5.291s sys 0m4.677s Booted on the good machine but physical disk still on the problem machine: real0m57.721s user0m5.446s sys 0m4.783s I was running these at the same time - which I think rules out cpu issues. (I've done other tests that also suggest that cpu/memory isn't the issue, it seems to be disk, cabling etc).

Hace poco actualicé a Debian 12 y ahora me salta una actualización de VisualCode desde el propio programa, pero no desde los repositorios. No es que necesite actualizar de la 1.85.1 a la 1.85.2 pero me planteo la siguiente pregunta. Si quisiera actualizar ese programa según la página del propio programa y sus propios lanzamientos ¿cómo podría hacerlo? ¿dpkg? ¿apt? Synaptic? ¿cómo afectaría eso a futuras actualizaciones del SO? ¿Seríais tan amables de facilitarme links para aprender acerca de las actualizaciones de paquetes fuera de las fuentes de la distribución y sus consecuencias? Muchas gracias y un saludo

Regardless of which grammar rules are right, wrong, or optional, the point of this is that parsing natural language text is *stupidly difficult*. A person who has to ask why "grep -c" doesn't count the number of commas in a single line of text probably isn't able to take on this quest. Any serious inquiries about natural language parsing should be directed to an appropriate artificial intelligence mailing list instead of this one.

I actually have a quarterly reminder for myself to review my various systems and take notes on changes. Installed packages, make sure config files are captured in source control, was I running any A/B experiments to see if I like a new font better than the old one, etc. While most of this I do as I go along, I find having a regular true-up is useful to make sure I didn't miss anything.

On mailinglists does mean meeting them half way, meet on common ground. Think "help those from whom you want help". For starters a Subject line that matches message body content. Good subject lines are a huge help with "What is it about?". Good subject lines also transmit "I have put effort in composing my email, you are invited to put in further effort". And yes, bad subject lines transmit "Minimal effort from my side, expecting minimal effort from your side" also "Here laziness, tell me what I can buy with it". The real challenge goes inside the email. Aim for "very good", settle for "good", stay away from "good enough" for others and stay away for "perfect" for yourself. Go for "interresting for all", avoid "I have a problem and you must help me". Ahd there is another import thing. Understand "world wide", understand the concept of time zones. People on this mailinglist are from across the globe, so from different time zones by definition. It means seeing much emails that were written while you were sleeping, it means you will be writing email for some that are sleeping. Do NOT assume that recievers does know what preciously has been written, so do not top post. Reply below precious text. Make it possible that your audience can read in the discussion order. When I see "top post", I think "the life form does not know to whom they are writing". And wonder "What else are they missing?". Groeten Geert Stappers -- Silence is hard to parse
