Hello:
... don't understand this part:
I don't have one of these HP multi-things so I'm relying on what you can tell me.
I avoid anything multi, better to do just one thing and do it right.
I still use a ca. 1996 Umax S-6E, works great.
How is this device connected to you box?
Try installing simple-scan and see if it detects the scanner.
[root@devuan]# apt install simple-scanIf not, is there something called HP Toolbox installed along with HPLIP?
Does it have the option to install a Fax Printer?
If not, install it and see if it works.
Also check this thread, I think the solution may be there among many posters who had the same issue.
Cheers,
A.
Hello:
... Xsane Image scanner won't recognize it.
Open a terminal and run the groups command to see what you are a member of:
user@devuan:~$ groupsIf I recall correctly, you have to be a member of the scanner group to be able to use one.
If you are not a member of the scanner group, open a terminal, become root and add yourself to it:
[root@devuan ~]# adduser [userID] scannerLog out and back in again and run the groups command to see if it worked.
Here's a link to a page by HP (!) for troubleshooting the scanner in the 8025.

Hello:
While running/checking updates today, I have seen that my installation contains a 31MB firmware-amd-graphics package.
But ...
I do not have any AMD hardware in my box and don't plan to get any.
My hardware may be dated but it works perfectly well. 8^° !
According to Synaptic, both Removal and Complete removal will drag along the firmware-linux and firmware-linux-nonfree, both of which are meta-packages.
Between the three of these packages, it's roughly 83MB.
No big deal, but what for?
I think the only hardware that would need firmware would be Intel chipset with integrated e1000 and the Atheros wireless dongle which I am not using.
Could I remove these three packages without wreaking havok?
TIA,
A.
Hello:
... disable the Data Validation of LibreCalc?
It's not Data Validation, it is something else that these DHs enable by default, à la Microsoft Office.
Incredible that they have not learned anything from their nemesis' shortcomings ...
This is yet another feature called, not surpringly, autoreplace.
To answer my question: one turns off autoreplace by going to the menu bar, selecting Tools > AutoCorrect Options...
You then click on the Options tab and uncheck the "Use replacement table".
My apologies for the noise.

Hello:
I'm slowly starting to loathe LibreOffice almost as much as MSOffice, which I had always used till I finally moved to a Linux environment, not without a lot of grief and getting used to.
I'll make it quick as this is dangerously off-topic:
Does anyone know how to disable the Data Validation of LibreCalc?
This POS application keeps putting a number I do not want to put in a cell but I have not been able to find a way to get rid of this feature.
I'm working on a very long and complicated 20+ year monthly expense expense sheet which I have to keep up to date and I want to be able to audit it myself.
I do not trust LO to do anything but sum up columns the same way I did not trust MSO.

Hello:
why is there a sudoers file under /home/?
Absolutely embarrased cannot describe how I feel.
My only excuse is not having had my café au lait when I posted. 8^*
Of course it should not be there.
And the original is exactly where it should be:
groucho@devuan:~$ locate sudoers

Somehow got created in /home/groucho, it is empty.

Hello:
I make scheduled back-ups via a cron job running BackInTime.
Works well enough and has saved me from a couple of disasters.
But ever since I generated a sudoers file, I started to get an error message:

But I never wanted BackInTime to run as root so I left things as they were but there has to be a solution to this.
My user is part of the all the relevant groups ie: adm lp mail dialout fax cdrom floppy tape sudo backup staff lpadmin and has read and write access to the drive/folders where the back-up is stored by BackInTime.
Maybe a sudoers entry?
Any ideas?

I think it probably does not.

The nvidia-legacy 340.xx is the last driver with updates from Nvidia and has suffered very little change in the past years.
The cards it is for are no longer manufactured or supported, hence the 'legacy'.

Hello:
... install nvidia-driver on devuan (ascii or beowulf), especially for older cards?
Yes it is.
--->
Before posting, it is good practise to do a forum search to see if the question you need an answer to has already been posted.
For example, I'd say your question has been answered here.
Also, posting in two places asking for a solution regarding the same problem like you did here is not a good idea.
Both posts are related to the same problem ie: installation of nvidia drivers in Devuan ascii / Beowulf.
<---
I had an apparently unsolvable problem with the installation of nvidia drivers in Beowulf, specifically drivers for my twin Quadro FX 580 video cards which need to use the 340xx-legacy (340.108) proprietary drivers.
Do give the whole thread a good read, it is worthwhile information.
The solution came from HevyDevy (post #21) who after analysing the problem took the time to figure out how to install the drivers without the errors I was getting.
I followed his instructions and the problem was gone.

Hello:
Either check ~/.xsession-errors ...
Spot on! 8^D
(thunar:2500): Gdk-ERROR **: 16:08:14.176: The program 'thunar' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadWindow (invalid Window parameter)'.
(Details: serial 18413 error_code 3 request_code 141 (Composite) minor_code 8) <---- here it is
(Note to programmers: normally, X errors are reported asynchronously;
that is, you will receive the error a while after causing it.
To debug your program, run it with the GDK_SYNCHRONIZE environment
variable to change this behavior. You can then get a meaningful
backtrace from your debugger if you break on the gdk_x_error() function.)Commenting the compton & line in /home/groucho/.config/openbox/autostart solved the problem.
So it seems that there will be no compositing for me in Beowulf+Openbox.
But the .xsession-errors file is absolutely huge, Way over the 6000 line scollback I've set in terminal so I cleared it with :> and will start to check all that.
Thanks for your input.

Hello:
As I want to rid myself of Xfce, at the moment my Beowulf installation's desktop runs on Openbox with Tint2 and Compton.
There seems to be a problem with 'drag and drop' which I have found happens in Thunar and Palemoon.
eg:
In Thunar, when dragging a folder or file ... when I put the mouse pointer on the file, press left-button and as I try to move/drag it, Thunar shuts down instantly but mouse and tint2 works. ie: I can restart Palemoon.
In Palemoon, if I try to drag a site from the address bar, it shuts down, mouse will not drop down menus and tint2 goes down.
Only way out is to Ctrl-Alt-Bksp to exit and log-in again.
I can drag open windows from one end of my triple screen layout to the other.
Everything is updated/upgraded and no dependencies are missing.
Any idea as to what may be happening here?
Thanks in advance,

Hello:
... patch to eudev so that only root and members of the kvm group can edit the node ...
Please correct me if I am wrong ...
Am I to understand that the Alpine distribution has issued a patch that basically backpedals on what Poettering so stubbornly pushed through?
And that in doing so, the line in dmesg complaining about group 'kvm' not being found is then not generated by the system?
TIA
A.
Hello:
No, the kvm group is one of the kernel developers' ideas.
You are quite right, I did not express myself correctly.
I should have written: ... seems that setting the /dev/kdm to world-read-write was ...
... allows users to access hardware virtualisation (via /dev/kvm) if they are a member of the group.
Why not do it when installing qemu-kvm?
Not a question that I bring up for I would have not known of its existence if I had not looked at my dmesg, which I always do.
It was so out of place that a maintainer actually filed it as a bug. (see the thread I linked to)
... Alpine system creates the group when the qemu package is installed ...
Yes, as it should (if it needs it, obviously).
Right?
... why is a random error message so important?
Because ...
... it is there?
... people who know much more than I have made what seems to be a strong case against it being there/generated?
... the (seemingly valid) arguments against this were railroaded by Poettering?
Isn't that how systemd came to be?
You may or may not agree with me, but it is not so much what is there but how it got to be there.
... ignoring it is a definite option ...
... creating the kvm group manually would be better than editing ...
I agree.
Should I create a 'kvm' group to get rid of the dmesg line?
Thanks so much for your input.
Cheers,
A.
Hello:
... hotplug event generated when the "kvm subsystem" ...
... by the hotplug handler (aka udev/eudev) via that "rule"
... to create the device node "/dev/kvm" with the particular permissions and group.
I think I got the right idea. =^)
... same actions by hand ...:
# mknod /dev/kvm c 10 232 <- this was also done in ascii # chmod 0666 /dev/kvm <- not this # chgrp kvm /dev/kvm <- not this
Commenting out the rule ...
... absence of the device node
... not the sub system itself ...
Just commenting out chmod 0666 /dev/kvm and chgrp kvm /dev/kvm (reported as a bug in the thread I linked to) should suffice.
... until there's some software needing it ...
From what I have read (not nearly enough) it seems that it is something used solely by the qemu-kvm package.
eg: I run a couple of VMs via VirtualBox in my ascii installation
groucho@devuan:~$ uname -a
Linux devuan 4.9.0-13-amd64 #1 SMP Debian 4.9.228-1 (2020-07-05) x86_64 GNU/Linux
groucho@devuan:~$ The node is there: (the cpu-checker package does not seem to be in the ascii repository)
~$ ls /dev/kvm
/dev/kvm
~$ I don't have a 'kvm' group:
~$ grep kvm /etc/group
~$ ... ideal modularization principle, the device node would rather be created as needed by that software ...
Yes, under the modularization principles that governed Debian development and maintenance from the start, crap like this would never have happened.
Nor would a thread as the one I linked to even existed.
That's where we are.
Thanks a lot for your input.
Cheers,

Hello:
Hi
What about "apt purge qemu-kvm".
... get rid of configuration files of all previously installed ...
I don't think that would have any effect.
The qemu-kvm package was never installed and I think what is happening is not because of configuration file from the qemu-kvm installation.
~# apt purge qemu-kvm

~# Normally, the qemu-kvm package would set up a 'kvm' group and set up user r+w access to /dev/kvm.
For reasons that do not seem at all clear, this has changed in Beowulf.
Like ralph.ronnquist points out, now the system has a default udev rule (set up at OS install time and overwritten on every update) that wants to set /dev/kvm to world-read-write.
I expect that it also wants a 'kvm' group and not finding it, prints out the result in dmesg.
At least that is how I understand it, corrections welcome. =-)

Hello:
... surgery of /lib/udev/rules.d/50-udev-default.rules might be sufficient ...
Right.
I'll try that.
But ...
The file starts like this:
# do not edit this file, it will be overwritten on update# The static_node is required on s390x and ppc (they are using MODULE_ALIAS)
KERNEL=="kvm", GROUP="kvm", MODE="0666", OPTIONS+="static_node=kvm"Is this ^^ the line?
I guess I could comment out the whole line, see what happens and remember when an update comes along.
Q: isn't s390x a 64bit IBM mainframe and PPC PowerPC?
ie: need a diiferent kernel than the one (amd64) we're using?
If so, what valid motive is there for this 'kvm' group thing?
I'm not a maintainer, coder or even an advanced user but I get a bad feeling when I see things like these being done in this manner ie: just because.
From reading the thread I linked to I cannot but suspect that, coming from systemd's creator, there may be something else behind this.
But then that's just me.
Thanks for your input.
A.
Hello:
I'll have a read.
But you know I have a thing for cats. 8^D
Do you have QEMU installed?
No.
... the qemu-kvm package creates that system group.
Yes, but if I'm not installing qemu ...
Does that [VMWare] use KVM for hardware virtualisation?
Apparently not.
From what I make from the thread linked below, only the qemu package uses it.
I found a bug report from 2017 with respect to this here -> https://github.com/systemd/systemd/issues/6360
It would seem that PR #5597 introduced a rule for /dev/kvm in Debian unstable, the result of which is the line in dmesg and someone filed the bug report.
This now causes a journal error.
systemd-udevd: Specified group 'kvm' unknownin any place where it doesn't exist. That could be initrds, non-x86 systems (which don't have this concept) or simply machines which don't have QEMU installed, where it doesn't make sense to create the group. "kvm" is not at all a generally useful and LSB defined standard group, so creating it everywhere seems like a waste.
What the OP wrote makes (to me) a lot of sense, more so if we take into account that there seem to be no applications which would need a system generated 'kvm' group save the qemu package.
The thread is really worth a read.
It seems this 'kvm' group was another one of Poettering's brilliant ideas.
And as such, it was shoved through in the usual fashion:
Anyway, I am very sure that /dev/kvm should be considered a standard system concept now, sharedby apps, and generic enough to be set up by systemd properly. I hope this makes some sense, and will close this now...
There you have it.
That's how we got a systemd-udevd: Specified group 'kvm' unknown line in dmesg.
@Poettering: no [asshole], it does not make any sense.
Cheers,
A.
Hello:
While trawling log files to fine tune my new Beowulf, I found this in my dmesg output:
--- snip ---
[ 14.484174] udevd[395]: specified group 'kvm' unknown
--- snip ---Quite so, the group 'kvm' does not exist ...
~$ cat /etc/group | grep -i kvm
~$ ... so I guess it is unknown.
I have seen some chatter on the web with respect to this but as it seems (?) Poettering is involved, I decided to ask here.
ie: people argued against and he argued for.
I installed cpu-checker and ran it ...
~# kvm-ok
INFO: /dev/kvm exists
KVM acceleration can be used
~#... confirming that /dev/kdm is there.
Why?
I run my VMs with VMWare but have not installed it yet.
Why does the kernel/system generate /dev/kvm and but does not also generate a 'kvm' group, maybe just empty?
Should I create a 'kvm' group to get rid of the dmesg line?
Thanks in advance,
A.
Hello:
... installer includes Recommends by default.
I see.
Not so 'bare-bones' as I expected a net-install to be.

alt-F1 to get back to the installer.
Thanks for the heads-up, good to know.
I'm not doing installations so often, but I'll keep it in mind.
On the other hand, maybe it would be easier to make a list of the Recommends included in the net-install and a script to purge them when the installation is finished and you are logged in as root for the first time.
