This does bring up two related points: 1. When you give time to help someone else it generally helps you too. In the sense that if you help out on this mailing list, trying to figure out how to help solve other people's problems, you learn about solutions that can be helpful to you as well. And you learn more about how systems work in general. If you maintain a package or write free software, it's generally packages or software that you yourself would find useful. When it comes to money, it often does not help you. Burning a live CD and mailing it to someone else, involves both time and money but doesn't help you. 2. In this specific scenario of live CD, there's an element of the saying, give someone a fish and you feed them for a day, teach them how to fish and you feed them for a lifetime. So you send this CD and they run or install the current version of the OS. Later on their system breaks down or they get a new one, or they want the next version of the OS, and what do they do then?

I have noticed similar behavior here, and the culprit seems to be firefox. If I ignore it things get sluggish, and then the machine starts to thrash, until the only recourse is the power switch. If I notice it in time, close firefox and restart it, the memory used after I do that is significantly less than it was before.

Hi Nitebirdz, For people quickly scanning through a lot of messages that they aren't heavily interested in, I suspect it was easy to overlook the crucial word "encrypted" in your first message. I know I didn't notice that until your second message, which used that word a few more times. I'm not really paying attention to the latest capabilites that the installer might have, or to what any other distros are doing, but when I have attempted this in the past it appeared to me that the Debian installer does not directly support installing a fresh installation into a previously created LUKS encrypted volume. However it is certainly "possible" with some complicated tricks, and if you are prepared to risk accidentally destroying the whole encrypted volume if you make a mistake. That's what happened to me the first time I tried it. But I have adequate backups and alternative machines, so that didn't bother me. It is possible to trick the installer into opening the existing encrypted volume. Then (with numerous fiddly steps and using great caution not to make a mistake) the installer can then install into a new partition inside that, in the usual way. However the installation it creates will be broken and likely not bootable. Because we have tricked the installer beyond what it understands, it makes many mistakes. There will be problems with grub, with the cryptsetup configuration, and with the initramfs. That all then needs to be fixed by rebooting into an alternative environment that has cryptsetup tools available. Maybe the installer rescue system is capable of doing that, but I'm not sure because ... The way I currently manage my machines (which are single-user, not servers) is that for convenience I always have a minimal bootable linux rescue system including the cryptsetup tools available on the disk in a small partition outside the encrypted volume, and I use this for that purpose (I also run the installer from there). But I expect it could be done with any other alternative boot method. So, being totally unaware of your level of skill and interest, I want to strike a balance in the information that I'm giving you here ... If you have adequate backups and are interested in learning more about how your system works, this could be a good project for doing that. Your desired end goal is possible. I spent time doing it and I'm happy I did that, because now all my stuff is configured and encrypted the way I want it, and that feels good. On the other hand, my reaching that goal involved developing the skills required. I don't have time to write out a detailed recipe for you on how to do it, and I don't remember all the detailed steps without some effort which I don't have time for. I can only offer occasional hints like this message. I can't guarantee that any hints given will be correct or will not cause catastropic data loss. There's probably no shortage of people arou

Installation on a Lenovo IdeaPad Yoga 13
I have a Lenovo IdeaPad Yoga 13, with a Realtek RTL8723A wifi/bluetooth adapter, and an Intel 3rd gen core processor graphics controller. I have firmware-11.2.0-amd64-netinst.iso from https://cdimage.debian.org/cdimage/unofficial/non-free/cd-including-firmware/11.2.0+nonfree/amd64/iso-cd/. I did find this report, https://wiki.debian.org/InstallingDebianOn/Lenovo/IdeaPad%20Yoga%2013%20(Wheezy). Has there been no progress on this hardware since? Should I get a USB-> Ethernet adapter for this beast? If so, is there one that d-i is known to support? Some issues: 1) The graphics are terrible. Both graphical and text mode are scrunched into the top third or so of the screen, with two copies across the top. They are damn near unreadable. 2) How do I tell it how to pre-seed? In booting I never get access to the boot command line. 3) The network device is never correctly detected, automatically or manually. I think it figures out that it is a Realtek, but doesn't go any further. I was unable to find the WiFi adapter in the manual selector, probably due to the atrocious graphics. I tried several 8723X drivers, but d-i didn't like any of them. I think the firmware package supports it, and I think the driver (8723au) is in the kernel.

The kernel selects the only appropriate hardware module (driver), which is provided with each individual kernel, automatically. The X systems are highly competent at selecting an appropriate display driver for Intel IGPs.

Plopping a disk from one PC into another is pretty routine here, not a big deal in most cases, but could be if you've set MODULES=dep instead of MODULES=most in /etc/initramfs-tools/initramfs.conf. Traditionally it's been necessary to restore most and rebuild initrd before the switch when going between AMD and Intel. I haven't tested in a while whether that's still true. IMO, NIC poses the biggest potential nuisance, if your new hardware is too new. If network works, other things are usually easily fixed, if they even broke. A quite new potential obstacle is newer Intel motherboard chipsets do not enable the UEFI BIOS to provide a CSM boot option. The B560 chipset in my Rocket Lake LGA1200 does not. According to Asus, all 500 series Intel chipsets are this way. If you put your disk with an MBR configuration in and it isn't recognized as bootable, this could be the reason, and a pain to correct. -- Evolution as taught in public schools is, like religion, based on faith, not based on science.

There are several reasons I'm not ready to do that: 1) Vivaldi is not open source. 2) It's based on Chrome, which empowers Google and its ability to control web standards. 3) I am worried about a web monoculture.

As I mentioned in another post, I do this occasionally, but I'm not sure how to interpret the results. I just killed firefox; I got back about 3.5 GB, but the system is still using about 4.8, and Xorg's usage hasn't changed: ~ 4436M / 3081M / 105M. Celejar

Fair enough, although the question then is why we enjoy giving of our time but not our money. I assume that a primary motive of many (I can't speak for anyone in particular, of course) who give of their time is a desire to help others, and the act of helping others is what provides enjoyment to them, so then the question is why they would not enjoy helping others with financial contributions.

I did use to have a root window constantly open and "Ctrl-a r" is still opening a 'sudo -i' window in tmux. The trouble with that is that I would tend to use the root console for non-root things. Besides, it's annoying to 'cd' in the non-root terminal in some deep directory structure only to find out you need root permissions to do what you actually needed to do when you got there. With sudo I'm incentivized to use non-root as much as possible, even if only because I'm too lazy to switch terminals or type 4 letters and a space ;) Kind regards, Andrei -- http://wiki.debian.org/FAQsFromDebianUser signature.asc Description: PGP signature

So it's only natural for your OS to try and put that memory to use. Any "free memory" is memory that could potentially be used for something more useful (IOW "free" = "wasted" in some sense). It's normal for memory use to increase over time, as your OS finds more things to put into it. That was my first intuition, too. There is even a classic website about this very topic: https://www.linuxatemyram.com/ HOWEVER, given that the OP mentions looking at the RSS sizes I think the classic "all memory used" issue is already ruled-out. The issue seems to be modern webbrowsers which could be considered OSes on their own already hence they also claim more resources whenever it is useful for them. Firefox takes just above 1600 MiB here with only six tabs open for four hours. Yet I am pretty sure it would take less were this a "lower-end" system e.g. fewer CPU cores would cause fewer processes to be spawned and hence the memory efficiency might be better in such cases.

You seem to have very limited internet usage. This is unlike many of us here. I keep my e-mail client and browser profiles (separate profiles for each multi-tab window, each profile has separate purpose also for security reasons) open 24/7.

To be honest, I'd be tempted to just use a standard Debian installer. If you have a machine which only has UEFI and refuses to boot a 64 bit Debian live at any point - at that point, you can look to say whether it's one of the outliers with a 32 bit BIOS and 64 bit CPU. There was a rash of netbooks a few years ago with 2GB RAM for just this reason they were sold with cut down 32 bit Windows versions. Hope this helps, all the very best, as ever, Andy C.

Memory leak
Hello, I seem to have a serious memory leak on my system (Lenovo W550s) - the memory usage seems to slowly but more or less steadily keep increasing. This is a more or less normal (I think) desktop installation of Sid, running Xfce4. Typical applications used are Firefox (currently with just one extension: uBlock Origin), LibreOffice Writer, Sylpheed, Xfce4 Terminal, and Liferea, all from the official repos. I used to have 8 GB on the system, and it would start to thrash at about 7+ GB usage. I recently ugrade to 16 GB; memory usage is currently over 8 GB, and it seems to be slowly but steadily increasing. I have never been able to wrap my head around linux memory usage reporting. htop currently reports about 8.13 GB used (up from about 8.03 when I began this email). I sorted the processes by PERCENT_MEM, and here are the leaders (VIRT / RES / SHR): A half dozen or so Xorg processes: 4340M / 2947M / 90948 Numerous 'firefox' processes: 5102M / 1068M / 369M. Some soffice.bin processes: 1096M / 301M / 128M. A bunch more '/usr/lib/firefox/firefox' processes: 27.2G / 213M / 88620. Some webkit processes: 100G / 212M / 143M. Some liferea processes: 84.3G / 198M / 112M A bunch *more* '/usr/lib/firefox/firefox' processes: 2835M / 186M / 127M And a bunch *more* '/usr/lib/firefox/firefox' processes: 2456M / 180M / 150M And then several more bunches of '/usr/lib/firefox/firefox' processes, with values of the same orders of magnitude to the preceeding ones. My understanding is that it's the RES and SHR values that are important, not the VIRT ones. I have the impression that the Xorg values are high. I saw recommendations to use xrestop to check things like pixmap usage. I don't really know much about this, but currently the total pixmap usage is about 360M, mostly used by a Writer process, and about 40M for Xfwm4 and 30M by Firefox. Any ideas? Celejar

The disk partitioning tool only shows the actual partitions, but no trace of the already existing encrypted volumes. See the screenshot attached. I'm testing this using QEMU. No matter what entry I select on that screen, it wants me to continue partitioning, and ends up destroying the previous setup. I cannot see a way to just get it to notice the already existing layout.

Fair points, certainly, although many people spend much time even on very minor packages, and on helping people with very niche questions, where their answers are really unlikely to help hundreds or thousands of people. > If you donate the money that you make in an hour to postage and > media for DVDs or USB sticks, somewhere between a fraction of a > person and a couple of hundred will be helped -- for an average > US income, about 2 USB sticks. > > Money is great, but it is needed in business-sized quantities. > Any individual person with skills makes the community better off by > answering questions and fixing bugs than they would by donating > the equivalent time in money. > > As a corollary, if you can spend a couple of hours convincing a > business that runs Debian to donate some money, that's probably > an excellent use of your time.

That's easy: time is much more effective than money in this context. If you answer a question on this mailing list, it is recorded and can be searched; hundreds or thousands of people can be helped. If you fix a bug in a major package, millions of people will be helped. If you donate the money that you make in an hour to postage and media for DVDs or USB sticks, somewhere between a fraction of a person and a couple of hundred will be helped -- for an average US income, about 2 USB sticks. Money is great, but it is needed in business-sized quantities. Any individual person with skills makes the community better off by answering questions and fixing bugs than they would by donating the equivalent time in money. As a corollary, if you can spend a couple of hours convincing a business that runs Debian to donate some money, that's probably an excellent use of your time. -dsr-

The relevant stat is the total data written specification. It's usually in "terabytes written". For a 1 TB SSD, 300TBW is bad. 600 is pretty bad. 1200 is okay for a desktop. 1800 is reasonable for some server applications. A Seagate Firecuda 520 specifies 1800. An XPG Gammix specifies 740. A Micron 9300 MAX is about 10,000. -dsr-

You might consider telling Windows to use UTC as well. For example here: https://feldspaten.org/2019/11/03/windows-10-clock-in-utc/

/etc/adjtime (setting the hardware clock to local time on Debian 11)
According to https://wiki.debian.org/DateTime There should be an /etc/adjtime file to configure the timezone for the hardware clock. I have no such file in my Debian 11 laptop. May I know if the file was removed and what was it replaced with? I just want to set the hardware clock to local time since this machine is shared with Windows and the clock is actually local time. Thanks in advance, and best regards.

Mine hangs because it's shutting down Firefox (Nightly from their website these days). Just as example, if I log out then log back in and run "ps aux|grep firefox" after logouts that take a long time, there will most likely be a long list of associated PIDs still in operation. If I try to launch Firefox at that moment, it will most likely fail with an advisement that a Firefox instance is already running. If I wait a few more seconds then try again, Firefox will FINALLY have shut down the rest of the way. It's been ages since I first realized that was occurring. It was an eye opener into that there's still a lot to learn about how operating systems and their packages work under the hood. :) Cindy :) -- Cindy-Sue Causey Talking Rock, Pickens County, Georgia, USA * runs with birdseed *

I've found that systemd takes down the network connections before it unmounts disks, so if I forget to unmount them before shutting down I get this delay. -- Tixy
