Do in a running vim :set mouse-=a and check whether you get better copy+paste behavior.

copy/paste in vim (in terminal)
Hi all, This often annoys me, but usually not to the point of posting about it. I used to be able to use my mouse to select/paste 'normally' (for X), when using vim in a terminal. More recently (a few years?), it doesn't seem to work. If I'm using gvim, it's fine. If I'm using anything else in a terminal, it's fine. Actually I think I can paste _into_ vim in a terminal, but have to use the menus to do it, rather than just middle-click. Any tips on getting the old behaviour back? Or reasons/tips why I shouldn't, and what to do instead? I'm using xfce4-terminal, and this generally only applies when I'm editing on a remote server, or editing as root - otherwise I usually use gvim. Thanks, Richard

Both these sound rather hardware-ish to me. I hope Albretch hasn't zapped something with static when making the modifications. Take a look at this reference. The user suspected the keyboard and even replaced it twice without fixing the problem. It turned out that the connection between the keyboard ribbon and the mobo was bad. So Albretch might want to reseat some of the connectors. I hope Eugen's Dell laptop is simpler to open up than the Lenovo I'm typing on, if that's the course of action chosen. https://www.dell.com/community/Laptops-General-Read-Only/XPS-M1330-laptop-keyboard-bottom-row-enter-spacebar-not-working/td-p/5163670 Cheers, David.

I just can't see the point in complicating this more than I have to. $ cat /etc/cron.daily/send-hotmail #!/bin/sh [ -x /root/.cron/send-hotmail.sh ] || exit 0 /root/.cron/send-hotmail.sh $ cat /root/.cron/send-hotmail.sh #!/bin/sh mailx -s 'ZZZ---ZZZ' myfreeacco...@hotmail.co.uk < /etc/mailname $ … sends my home's IP address each day to a location I can read from anywhere. Naturally it breaks the Subject line's "third-party server" condition, but judging from others' comments, this appears to be a matter mainly of semantics, calling servers "peers". Some might say that having to register for an email account (if you haven't already got one) is just the same as registering at one of these free dynamic DNS services. Having looked at them, I would beg to differ; and I've had a much greater and varied use out of this free email account than I would get from the dDNS service. I'm also not interested in using DHT services (which must also run on "third-party servers/peers"). Cheers, David.

For most laptops, the data "target" is going to be directories in /home//, and for people who don't separate /home from /, that's going to be the / partition.

That's what I would call the idea (from the other thread) of putting a laptop's /home on an external drive, RAID or not.

Cada sucursal actuaba de forma independiente, al final del día sistema enviaba reporte de ventas e inventario al servidor central el cual procedía a cuadrar y contabilizar todo. Incuso este sistema cuando inicio era manual, había que enviar el reporte por fax a contabilidad y ahí se cuadraba todo.

He hecho pruebas con mount.cifs y funciona perfectamente, pero sólo desde una cuenta de root. No me interesa meter a ninguno de esos usuarios al grupo sudoers, pues sólo quiero que puedan montar y desmontar esos recursos y no tengan más privilegios. ¿Alguna idea de si es posible y cómo podría proceder?

Marco has a man page (online here [1]). In a typical [censored] style, Marco has no config file: its config is woven into the dumpster fire^H^H^H^H^H^H^H^H^H^H^H^H^H gconf database. As to which config items there are relevant and what effect they have, the man page implicitly seems to have the words "good luck". But perhaps, just perhaps, you manage to find there how title bar fonts and colouring. My favourite hypotheses are those two: Marco is using a font to render those titles which it somehow can't display or it is displaying things fine, but with the same foreground and background colours. But I'm more than willing to take a third hypothesis into my collection :) Cheers [1] https://manpages.debian.org/buster/marco/x-window-manager.1.en.html - t signature.asc Description: Digital signature

The only other necessity is the ability to use the "Dvorak Classic" keymap (which differs from the Dvorak ANSI map offered by the installer).

It's near impossible to predict how your usage will evolve so almost certainly one or more of these will fill while others remain near empty. If you want to do this, use LVM and pick minimal capacities for all Definitely. If you really want to have separate file systems for all those mount points (and maybe even if you only have a few separate ones), use LVM. Instead of having your mount points' file systems directly on real disk partitions, which are harder to re-size, sometimes needing time-consuming copying to empty space on a disk, you'd have your file systems on virtual partitions (LVM logical volumes) that can be re-sized easily. (LVM uses the real disk partitions as LVM physical volumes, from which space can be allocated to the LVM logical volumes. One suggestion: When you set things up, learn how to extend a logical volume and enlarge its contained file system and then write down instructions/reminders for yourself. When you run out of space in some file system in the middle of doing something else (likely months down the road), you probably won't remember the LVM details you haven't thought about since you set things up. (I have my file systems set up on LVM logical volumes, the LVM physical volumes set up on RAID arrays, and the RAID arrays set up on pairs of partitions on my two disks. Having detailed instructions, for, e.g., enlarging a file system and for replacing a failed disk, already written down saved a lot of time and headaches and avoided mistakes.) Daniel the above, leaving the majority unallocated. You can then grow logical volumes as needed and the problem goes away. Cheers, Andy

If going back to i386 is an option for you, the department of workarounds has an option. I could install with the i386 non-free bullseye iso from https://cdimage.debian.org/cdimage/unofficial/non-free/cd-including-firmware/bullseye_di_alpha2/i386/iso-cd/ Basically that forces a BIOS mode installation, but be aware grub2 also in BIOS mode does not boot on this device. So what I did was just before the installer asks for your confirmation to reboot I switched to the shell on tty and did roughly the following: mount -o bind /sys /target/sys mount -o bind /dev /target/dev mount -o bind /proc /target/proc chroot /target /bin/bash apt install grub-legacy dpkg --purge grub-pc grub-pc-bin grub2-common update-grub grub-install /dev/sda exit & reboot. That basically replaces the known to not work grub2 with the old grub which already worked in the past. Did not yet move on from here. So in my bug that is so far two bugs: a) the touchpad does not work in the graphical installer b) grub2 does not work in EFI and BIOS mode You can probably afterwards also install an amd64 kernel image so you have a i386 userland with at least a 64bit kernel running. For the sake of random testing I also tried Ubuntu 20.04 and Fedora 32 and in both cases the grub2 efi installation fails as well. Quite sure that is a general issue between the UEFI on this device and grub2 which for some unknown reason worked or was workaround in the old grub. Not sure if that helps you to move on in any direction with this device. Sven

No scancodes for some buttons
I've got a very odd wireless keyboard. It look like TV remote, but is an actual keyboard inside. Some buttons work perfectly (VolumeUp, VolumeDown), some are not. I've dug into this topic, and found that there is a set of buttons which does not produce both scancodes and input events (scancodes in console ignores them, evtest ignores them). As the last effort I used usmon kernel module and Wireshark, and I found that 'silent' keys are actually cause the same number of USB events as working ones. The problem is that I have no idea how to read wireshark/usb output. I've started from 'working keys' and I can't understand a thing. What is URB? How to read dump if I can't find a 'button code' (for working keys) in the dump? Can someone help me with 101 on usb keyboards? Some kind of high-level overview with terminology, etc...

I hesitate to suggest what I'm going to suggest -- so I'd suggest you wait until you hear any responses from people that can suggest either a software fix or a software test. (Oh, see last line, maybe try plugging in an external keyboard (if that is possible) and see if you have the same problem.) I suspect it is a hardware problem, and what I would do is get the manual for the laptop and look into how hard it might be to clean the keyboard. You might try blowing out (or vacuuming) the keyboard (with canned air or a vacuum cleaner / blower with tools with small orifices). But if that doesn't work, and no one has a better suggestion, I'd look into trying to disassemble the keyboard to some extent and examining it and trying to clean it. I used to do this often with desktop keyboards, I guess I've been better lately at keeping them clean. Laptop keyboards can be much more difficult to dis- and re-assemble and keep them working. Hmm, one test I can think of -- try plugging in an external keyboard and see if you have the same problems (if there is a USB port (or other port for an external keyboard).

Just recently I discovered that a keyboard doesn't do anything when I hit one of these keys (german qwertz layout): qwer uiop 789+ They are all on the same row and I believe something broke inside the keyboard (I remember vaguely it having let fall down off the desk).

Some keys on the keyboard do not work
Hi, I have a Dell Latitude 5580 laptop, and have been a happy debian unstable user for 20 years. I have a very weird problem with its builtin keyboard which slows down my work significantly (ctrl-c, ctrl-x, ENTER etc. do not work): Since several months ago some keys on my keyboard do not work, in all the applications (e.g. gnome-terminal, emacs, thundebird, firefox). When I press on them, very often nothing happens (usually, I press on them for 10 seconds to make appear the character), sometimes the key appears twice, and sometimes it works flawlessly. When it works, it works for several minutes or several hours; similarly, when it does not work, it does not for several minutes or hours or days. I use very often suspend/resume, I also use xmodmap and awesome window manager, but I suppose this is irrelevant. The problematic keys are found on the last row: xcvm,. (but zbn work) and the bottom keys (ctrl, alt, window, however space works always correctly), plus ENTER key. I have always thought that it is a X problem which will get fixed. Interesting, a few days ago I noticed that on grub I have the same problem: c and ENTER did not work. So now I wonder if it is not a hardware problem, however sometimes it works for a long time! I have looked at Xorg.0.log, without seeing anything wrong. How can I track down where the problem is, and fix it? Thanks, Eugen

[...] Given that evidence, my guess is that the window manager is somehow botching the title bar dispay. Either it tries to use some non-existent font, or it's writing with the same background and foreground colour or something. Have you tried another "classic" X program? For example xmag or xeyes? This may be a hint -- either your window manager is specifically treating xterm in a special way, or the decorations of all "classic" X programs fail in the same way. Cheers [1] Of course it cannot actually "set" the title. It just can ask politely the window manager to do it. - t signature.asc Description: Digital signature
Re: Qt5 & SQLite
Hola, aparte de lo que te han comentado los compañeros de la lista queria añadir lo siguiente: si necesitas mostrar graficos 2D/3D tambien tienes la libreria SDL SDL es "solo" para graficos 2D, pero si tienes cierta habilidad puedes simular las 3D. Solo comentartelo, por si en algun caso te puede interesar dicha opcion. Un saludo

Aplicación en local o a través de red mediante cliente servidor? MariaDB/Mysql en local encuentro que no funciona fluído, puede que sea idea mía. Postgresql un cañon, quizás para lo que quieras hacer. Podrías revisar Firebird embebido o cliente servidor pero en local, Firebird es mucho más que sqlite.
