How well they run will depend on what you install. For comaprison, I built this system 12.5 years ago (Jan 2007). It's been upgraded numerous times since. The newest part is a 4 year old 500GB SATAII HD. The oldest, the 12 year old MB, an ASRock AM3. It has a Phenom II quad-core 3.0GHz CPU, 8GB DDR2(!) RAM. and a basic 2D, fanless GeForce 8400GS graphics card. It's currently running Stretch (sysvinit instead of systemd) with the Openbox window manager GUI (menus and single lxpanel). It runs Buster (LXDE desktop & systemd) quite well in Virtualbox 6.0 with 2GB RAM. So, it should run even better on the native hardware, but I'm not going to install it. However, that's another story. If you want better usability and performance with your old hardware avoid "heavy" desktops like KDE and GNOME. Stick with light one's -- LXDE or XFCE . . . OR . . . like I did, only a window manager. If performance is still not to your liking, try a lighterweight Debian-based OS like AntiX or something like Vector Linux. There are lots of linux distros designed for old hardware out there. Let us know how it goes. B

Re: August 10, 2019
The only way to know for sure is to boot into a live OS and see what works and what doesn't. Or install it and see. From my experience I'd say Linux supports everything except maybe stuff that uses TPM and some advanced/high end GPU functionality.

Re: August 10, 2019
You should check the debian documentation pages for hw support https://www.debian.org/releases/stable/amd64/ch02s01.en.html If some of your hardware is not mentioned there is a serious posibility that it wont be recognized from the OS. The most common firmware missing are graphic cards and wireless cards. Some are packaged in the non free repositories https://wiki.debian.org/SourcesList.

you can edit lightdm.conf/lightdm.conf

yes I did
below this header
#

find these lines
# autologin-user=
# autologin-user-timeout=0
uncomment the first and add the user name
uncomment the second line if you want autologin (no password)
Uncommenting that line won't change behaviour as the comments give what
the defaults are. If you set a value for autologin-user then that user
will be automatically logged in without asking for a password (this is
what I use). I believe setting autologin-user-timeout to a non-zero
value will delay that number of seconds giving the user chance to
cancel auto-login and select another user. I don't know if that matches
the behaviour Tom is looking for or if he always requires a password to
be entered.
correct, I also use autologin but only on single user systems.
forgot about setting the timeout, yes that works too.

No way José. I haven't actually insisted on that, but I've certainly thought it :-) Similarly, one of our local fuel stations has (or had) vouchers that say things like '10c per litre off every litre of fuel' - which also quickly gets into trouble if taken literally :-) Richard signature.asc Description: OpenPGP digital signature

Good day, In Debian 7, Mate desktop was not yet officially available IIRC, so the default greeter was most likely gdm3. I see in Debian 10 that Mate desktop depends on lightdm, which is different greeter. The default behaviour of lightdm is to hide available user logins on the machine, in order to avoid leaking this information in situations where the location of the machine is untrusted. > > you can edit lightdm.conf/lightdm.conf > Do you mean /etc/lightdm/lightdm.conf ? Pointing to this file was the right direction. However, on the variables side, may I suggest to search for the character string "greeter-hide-users" definition, uncomment it in place, and set its value to "False"? There is also something that has bitten my hand, as this was a bit different in previous Debian releases. In the new version of the default configuration file, the "[Seat:*]" paragraph header is commented, so just de-commenting the configuration option is not efficient any more, you also have to put the header back. In the end, the paragraph might look like: # blablabla [Seat:*] # blblbl # [...] greeter-hide-users = False # blblbl You may have to type in your login one last time, so that the greeter knows which one(s) to print.

May be it will help to explain what is the desired usage of the system as many mentioned SDD and HDD is not good to mix. In the case I would use the SDD for the operating system and not sensitive data that is written more often for example a scratch box. The HDDs you can put in RAID1 and probably now and then backup your configuration from the SDD, so that you can recover if the SDD fails. It is not likely but it happens more often than you can think.

And they do run Debian... I don't have that modern RPI, but usually there are ready images to use. Did you try one? I personally ended up using TFTP boot. The only thing I had to prepare was an old SD card to hold the boot loader. If the HDMI does not come up ... I don't know - this should be there IMO regardless of boot.

I have done RAID1 on mdadm; I believe mdadm can do JBOD, See mdadm(8). If this is a new install, you should be able to achieve either or both via the Debian Installer by selecting manual partitioning. But, as others have said, two HDD's and one SDD in JBOD (or RAID) is not optimal. Without specifics such as anticipated usage, data storage requirements, drive makes and models, available drive bays, HBA/ motherboard makes, models, and available ports, etc., it is difficult to make recommendations. In general, I put boot, swap, and root on one small SSD and put bulk data on RAID large HDD's. David

RPI boot problem (some OT)
I know this isn't the best place to talk about Raspberry Pis, but there are people here who are familiar with them, and probably people who can point me to the correct place. And they do run Debian... My 2G RPi4 arrived yesterday, and it doesn't boot, not all the way anyway. The red power led goes on, the green 'disk' activity led flashes, it displays the square rainbow flash image, but doesn't go any farther than that (the green led stays on). The rainbow display stays on forever, as far as I can tell. I've already tried: Loading a known working 3+ Buster -- did nothing; no surprise. But that chip was built from the same Buster NOOBS file as the one I prepared for the 4. Replacing the SD chip -- no difference. Reloading the SD chip -- no difference in the boot process. When I went to gparted to repartition the chip, it looked like it had begun some of the Raspian partitioning. But it hadn't finished; there was a huge area that was still available. Downloading and installing a different NOOBS file (lite instead of full) -- no difference. Looking for help on the RPi website -- very little help; they talked about a new bootloader and told me how to see if I needed it. I didn't (the green led comes on and blinks). And I already knew how to plug in the HDMI cable :-) Looked for help anywhere on the web -- lots of other RPi4 boot problems discussed, but not mine. Giving it an hour or so to cogitate and go on to the next step -- the rainbow was still on the monitor, but the green led had gone out. This is not the first 'Pi I've loaded a Raspian OS into (the 2 was the first), and I followed the same procedures I always have. It is, however, the first time I've had any trouble at all. The 'Pi seems OK to me -- it does display that flash screen, and that takes working some CPU cycles and some working RAM. I don't think the software's bad -- it seems to do quite a bit of stuff trying to boot. I'm at a loss. A solution/suggestion or a URL would be greatly appreciated. -- Glenn English

I think that having the entire machine set to UTC for all users is unusual, but if that's what you want, then it's unlikely that you don't have root access. Assuming that is so, then the normal course of action is: $ sudo /usr/sbin/dpkg-reconfigure tzdata and then select "None of the above". This will give you a list of GMT-based timezones as well as UTC. (If you care about the difference between them, or TAI and the business of leap seconds, then you've more reading to do.) The debian-installer tries to keep things a little simpler, and guide the majority of people towards typical choices. If you're desparate to get the timezone altered earlier in your installation process, you could always do it manually: try switching to VC2 and editing the file /target/etc/timezone to the string UTC (the alternatives are simply the names of the files in /usr/share/zoneinfo, including subdirectories). Obviously wait until the file exists. (I've not tried this so I don't know when that is.) Cheers, David.

Re: history/history.db files appearing
Thank you, David, Judah Richardson, and Richard Hector, for your suggestions; unfortunately, the appearance of the history.db files remains a mystery. > Do you have some kind of backup, sync, or versioning application > running? I have a daily cron job that runs rsync to copy my home directory to a backup disk. That's been running for several years without any changes.

Nothing in /etc or /var; most are in my home directory (and now also the backup disk to which it's been rsynced), mostly in directories where I've edited text files, although there is also one in a Videos directory on a different mounted drive. There is also one in /tmp. Not counting the backups, there are 13 of these files, appearing at a handful of times between Jul 22 and Aug 8.

I was under the impression that airline pilots were paid enough to buy two-zone wristwatches, but perhaps the threatened strikes are an indication that they don't think they are.

That sounds like a combination of trying to drive it at a non-native resolution (blurriness) and a bordering-on-bad cable (small black lines). I would start with a new cable, and then checking /var/log/Xorg* to see if the monitoring is giving a proper EDID resolution block (and that the driver is using it). > A friend of mine offered to give me a MSI GeForce GT 710 graphics card > for free.

That card is old enough to work reliably with Nouveau, so most of it will be: apt install xserver-xorg-video-nouveau making sure you don't have anything conflicting in /etc/X11/xorg.conf or the configuration subdirectories and rebooting. You may need to tell your machine's BIOS to select one card over the other, and so you may need to switch which card the monitor is plugged into along the way. -dsr-

You might try running a script that takes a snapshot of ps output every minute (just processes owned by you) and then reconciling the timestamps on the .db files with what you were running at the time.

"Expensive" is a dimensional term, like length and time. "Cheap" is in a different category, like shortness. A 6-inch nail is twice as long as a 3-inch nail, but one doesn't say the latter is twice as short. But if someone asked for a nail twice as short as this (holding up a 6-inch nail), you might assume they were a non-native speaker of English, or you might notice you're almost twice as tall as they are: ie it's a child. (And it would be polite to offer them a 3-inch nail. Learning all the categories takes time, and some people might have slightly different boundaries.) It's pretty obvious that Reco's meaning for cheapness was meant to be understood as a reciprocal cost and not as a discount. It might be a legitimate idiom in some parts; who knows. One hears stories of pedants insisting they be paid to carry goods out of the shop because they were labelled "10x cheaper". No way José. Cheers, David.

Buster Mate: how to set default user nae
In an older version of debian (7 or so) I had my system set so the login
screen would show my user name as the default.
That went away after some version upgrade or reinstall and I've silently
grumbled about it ever since (especially when I inadvertently flash part of
my password as my muscle memory has me entering it in the blank user name
slot!).
I have tried searching for the solution but so far have found nothing.
I have also tried "find ~/.config -exec grep -i user {} \; -print " and
found nothing that seemed worth a deeper look.
Can anyone help me?
Thanks.
Best regards,

Re: installing Debian 10 to 3 hdds as one big system
Le 10/08/2019 à 13:03, Pavel Vlček a écrit : I have computer with 3 hdds. One is ssd, 2 others are hdd. I want to install Debian 10 to all 3 disks as one big system. What do you mean by "one big system" ? One big filesystem ? Why ? What to use, raid or lvm? If you are concerned with performance, do not mix SSD and HDD in an LVM group or a RAID array (except RAID 1 with --write-mostly as already mentionned). If you are concerned with disk fault tolerance, use RAID with redundancy (not RAID "linear" or RAID 0). Note that you can set up LVM on top of RAID.

What to use, raid or lvm? Personally I would use the three devices as a RAID-10 which would result in half the capacity of the total (768G) and you could withstand the loss of any one device. You could instead do RAID-5 but I do not like parity RAIDs. In this case that would give you 2 devices worth of capacity and again any one device could fail. It won't perform as well as RAID-10. Other options that include redundancy would be btrfs or zfs. I would not do the redundancy in LVM. If not using btrfs or zfs, I would use LVM afterwards on the RAID device for management purposes. You can do all of this (except zfs) in the Debian installer. There is an MD feature called "write-mostly" which you can set on devices to tell the kernel that no reads should go to these devices unless absolutely necessary. The usual use of this is in mixed rotational and flash setups to try to encourage reads to come from the much faster flash devices. This could be of real benefit to you but sadly it doesn't work with anything except RAID-1. Other interesting approaches could be: - RAID-1 of the rotational devices then use the SSD in lvmcache. In writethrough mode it is safe to lose the (non-redundant) cache device: https://manpages.debian.org/buster/lvm2/lvmcache.7.en.html - RAID-1 of the rotational devices then bcache on the SSD: https://bcache.evilpiepirate.org/ Personally I don't find bcache mature enough and while lvmcache I did find to be safe, I didn't find that it improved performance that much, probably not enough to dedicate a third of my total capacity to it. If performance was my overriding concern I might actually do a 3-way RAID-1 with the two HDDs set to write-mostly. Only 512G capacity, can lose any two devices, good read performance. > I know, how to create the lvm with textual installer, > but I have problem expanding it to next two hdds, /dev/sda and sdb I would not do this, but… # Mark the new device as an LVM PV # pvcreate /dev/sda # Extend your current volume group to use the new PV # vgextend /dev/your_vg_name /dev/sda At this point you have added the capacity of /dev/sda to the existing volume group, but all your existing logical volumes still reside on the original PV alone. You can now convert them to have their extents mirrored: # lvconvert -m1 /dev/your_vg_name/some_lv The mirrored extents will be on /dev/sda because that is the only PV with free extents. If you already added /dev/sdb then the extents could be mirrored there instead. If you want to specify where the mirrored extents should go then you can do so by appending the PV device path to the above lvconvert command. You can instead/also stripe, using the --stripes option to lvconvert (or lvcreate, for new LVs). In this setup there would be no redundancy though, which is too bad for me to consider. Not doing anything special would leave your LVs being allocated sequentially from whichever PV has capacity, in this setup resulting in no redundancy and max performance of one device, so that would be the worst setup.

So something or the systen files is/are potentially split between ssd and hdd and you don't know where to get it from? Sounds like a "no idea" performance-wise. If you had 3 SSDs or 3 HDDs, ok, but.. If you want that "big space" and not care about data security if one fsailed I'd do system on a partition on the SSD and then do LVM on the rest of the SSD+the HDDs. Then you at least have the system on the SSD completely. (And you know LVM does nothing for security if one of your disk fails?). If you can live with "just" 512 GB home I'd say: system on the SSD (although some "waste" of diskspace...), RAID1 for the two HDDs mounted on /home for data security if one disk fails (of course doesn't save a backup for rm actions or so..)

A non expert or even an expert would choose his time zone. I think time ago in the time zone selection window the GMT/UTC existed as possible selection. Also after installation once can adjust the time zone anyway.

In fact I would do it the other way around. initial price x 1xtime x+(1*x) 2xtimes x+(2*x) this gives x=150 The problem is in the comparison - when you read the characteristics of the devices, there are couple of differences that can not be neglected, but I agree 400 is too much. I think fair price for such a device would be in 200-300 range, what we also see for the Lynksis router.

It seems to me like you are confusing the hardware clock (the internal clock of the computer, if it has one), the system clock (the clock of the operating system) and the timezone (translating the system clock to the clock shown to users)[1]. On linux the system clock is always set to UTC. The time(stamps) shown to the user are translated on the fly depending on the system or user's timezone. In practice this means there is global timezone set by the administrator (usually during install, but can be changed with 'dpkg-reconfigure tzdata') and users may also chose their own timezone as they prefer (think SSH server with users from all over the world). See for example the output of: $ ls -l /etc/issue vs $ TZ=UTC ls -l /etc/issue Unless you set your timezone to UTC during the install those two would show different timestamps. Depending on whether you are booting some other OS that uses local also clock internally (e.g. Windows) from the same hardware it might be necessary to set the hardware clock to the local time of the timezone you want displayed in that other OS. What problem are you trying to solve by having the timestamps of the initial installation be in UTC (which they are anyway)? [1] It certainly doesn't help that the installer is calling both system and hardware clock "system clock".

That was all that patents were ever intended to do: give the originator
a period of monopoly over that particular implementation of his idea.
It never covered different implementations.
That was in exchange for the inventor freely showing the world
('patent') how his device worked, precisely so that others could use
it later. It was never intended to grant a monopoly for half a working
lifetime, it was intended to discourage producers from keeping a
manufacturing process secret, which of course they have always been
entitled to do.
Closed-source code is secret anyway, definitely *not* patent, and ideas
cannot be patented, so the whole business is simply a demonstration of
the power of Microsoft, just as Disney dominates US copyright law.

Sorry, this usage grates with me. $amount cheaper that $price means subtract $amount from $price $x times $price means multiply $price by $x so "2 times cheaper (than $450)" is: $450 - (2 x $450) = -$450. signature.asc Description: OpenPGP digital signature

Twenty is too long. That would work against inventors as instead of buying useful patents companies would just wait 5 years and then use it without any charge.

The non expert lives somewhere relative to UTC, why should I use UTC. AFAIK it is always UTC in the background adding or substracting the timezone and perhaps summer time and other specifics. I do not want to calculate each time on top of UTC, what the time is.

Check with lsof. Any clues from what directories they appear in? Are they in home directories? /etc tree? /var tree? If you're familiar with sqlite (or even sql, and can google the specifics), you could dig around inside and see if you can get any clues that way.

Here's some output from a buster installation on acer. As it was my first, I kept the typescript. ... Thanks, David. For some reason on my first installation attempt, the menu hung and did not allow me to select ADVANCE OPTIONS -> EXPERT INSTALL. This is a notebook; I may have pressed two keys at one accidentally. But on a subsequent attempt, I was able to select EXPERT INSTALL, and that allows me to specify UTC. So for this installation, the issue is resolved. But I still think that even the non-expert should be allowed, if not strongly encouraged, to use UTC.
