How to call custom scripts from selections in konsole/dolphin

0

I use Kubuntu. In other to optimize some workflows I'd like to do two different (but related) things.

select some files in dolphin, right click on them, and have a custom menu option that calls a script of mine with the filenames as parameters.
select some text in konsole, right click it, and have a custom menu option that calls a script of mine with the selected text as parameter.

I hope those things are doable, I know how to write the scripts, but I have no idea how to do the right-click option thing.

Where has en_SE gone in 21.10?

2

I had a Kubuntu system (actually many) set up with en_SE.UTF-8 because it's the only locale that has: english, metric, YYYY/MM/DD and a few other non-stupid things. It was working great.

Then this morning I upgraded to 21.10 and this locale is gone. I used locale-gen and looked in some config files and there's no trace of it anywhere. So has it been renamed or do I need to generate it somehow ?

Switch user in Kubuntu gives black screen

0

I've had trouble with switch user for the last 2 years at least. For a long time the option was gone because of some deep regression. Now that it's back, it doesn't work. Activating 'Switch user' gives a black screen (no mouse).

What causes my laptop to wake up randomly?

1

My kubuntu laptop very often (always?) wakes up when I disconnect it from its dock (a USB-C connector to a dock with external monitor, network cable and not much else). It also seems to wake up at other times but I haven't been able to reproduce. I first thought it was kalarm causing the wakeups (I can hear the alarm messages), but the wake option is disabled and I haven't been able to reproduce. And after it woke up in my bag, it won't go back to sleep, so it's boiling hot and it drains the battery. If I put it to sleep on the desk and leave it there, it stays suspended.

It's a very recent model, up to date BIOS, with a fresh kubuntu install:

From the syslog I can't identify what caused the wakeup:

No more 'switch user' from sddm

7

I've searched extensively and there are many mentions of this problem but it seems only a few disparate users have had it over the last few months. But the 3 Kubuntu systems I upgraded to 20.10 all have it now, so I'm surprised it's not a critical bug with already a solution.

Description:

'switch user' is gone from the K / Leave menu
'Switch user' is gone from SDDM lock screen (you can only re-enter your own locked session). Shutdown / reboot is also gone from lock screen.
Maybe unrelated: when logging out some users (always the same ones), I get a black screen (for others I go back to a normal sddm screen with user selection). This is not related to the kde_settings.conf / MinimumUid issue

Out systems are family-shared, so it's really annoying. If the lock screen is on, the system has to be forcefully rebooted for another user to use it, with all the disk corruption risks involved.

Here's the result on one of the 3 systems. I don't see any smoking gun in it:

2021 update: after the upgrade to kubuntu 21.10, it finally worked as expected for a few weeks... until some update thrashed that. Now using the Switch User option leads to a black screen you can't recover from. I can still use Ctrl-Alt-F2 to kill and restart plasma, but it's bad. Will post more when I have time to gather data.

Impossible to select glossy paper when printing

1

I have a cheap Canon PIXMA Ip2880 printer. I tried to print a pic on glossy paper from Linux, but impossible to select either "Glossy photo paper" or "Photo Paper Plus Glossy II" in the page setup tab of the print popup. No matter what size print I try (I'm on A4 paper), it won't print and blink 11 times, which means "Paper type and paper size settings are incorrect". If I select "plain paper" it works.

Now, are there paper specific sizes that are allowed ? If so, which ones. And otherwise, how do I print on A4 glossy paper ?!? Thanks

High load average but low CPU from top

2

I'm trying to track down repetitive hangs on an oldish laptop (10yo, 4Gb of mem, 2 cores, Kubuntu 18.04) It now happens several times a day with moderate use (<10 tabs open in firefox, a bunch of other progs, nothing huge).

Sometimes I get a OOM but in most cases the user interface crawls to a halt for one to 30 minutes before things go back to normal. This is a recent occurrence (last 2 months). In most cases there's nothing in dmesg or syslog.

I've been trying to diagnose it without success, but one thing I've noticed with htop is that the load average jumps to 30 or more while the cumulative CPU usage stays below 10% and the memory usage (Mem+Swap) stays well below 4Gb.

1st question: how can the load average be so different from the CPU usage ? 2nd question: what else can I do? Can I run some stress programs and hope to get meaningful info?

[Edit] Still waiting for the next crash, but I notice that swapiness is at 0. Shouldn't it be 60 by default ?

Taking an action after connecting a USB-to-Ethernet adapter

4

When I connect a USB-to-Ethernet adapter (that has been previously used), I receive a MAC address, and then if there's something connected on the other end I receive also an IP address (192.168.1.1 in my case, configured in static in NetworkManager). On the other end there are various instruments that wait for the DHCP server running on that PC to give them an IP.

The problem is that the DHCP server refuses to start if the subnet is not found, so it cannot be launched before the connection is up. How can I do systemctl restart isc-dhcp-server.service after I receive the IP 192.168.1.1 from NetworkManager ?

I thought of using a udev rule with ATTR{address}=="f0:1f:af:3d:6c:e7" RUN+="systemctl restart isc-dhcp-server.service" but it runs before the IP is assigned. Is there a udev option I can use or do I have to use another method via systemd or NetworkManager or other ?

Mysterious KDE hang and/or restart

1

I use Kubuntu and it's been working fine for years, but in the past few months I either have regular (every few days) screen hangs where nothing responds for a few seconds to tens of seconds, or I get kicked back to the login prompt losing all my running programs (hardly better than a full reboot). I believe this is info related to those crashes (from syslog):

RDP via ssh stopped working

1

I run a headless VM (an old WinXP) on a Ubuntu server. I haven't used it in a while, and I just started it but it won't connect via ssh tunnel.

I start the VM on the server like this:

client $ ssh -CYL 3389:localhost:3389 dargaud@server
server $ VBoxManage startvm "OldXP" --type headless
server $ VBoxManage list runningvms
"OldXP" {ebb9b585-84b3-4057-8fc7-e3a43735abcd}
server $ VBoxManage list -l runningvms
...
VRDE: enabled (Address 0.0.0.0, Ports 3389, MultiConn: on, ReuseSingleConn: off, Authentication type: null)

Then I try to start rdp:

client $ krdc rdp://localhost:3389

The above starts an grey X11 window on the remote server, with a decoration-less firefox running in it.

client $ rdesktop localhost

The above opens a [login to xrdp] remote box asking for module, username and password.

I feel like the Windows VM is not listening on RDP anymore, but the status above seems to give the right configuration, and also:

If I kill the VM, there are no more listeners on 3389, so it's not a conflict.

How to reset kmail?

5

There must be some corruption to my message store (pop3) as kmail keeps crashing and hanging. I followed the following info to try and reset kmail: https://docs.kde.org/stable5/en/pim/kmail/clean-start-after-a-failed-migration.html but after point (3) all it did was clean up akonadi, all the messages are still in kmail, and it still crashes and/or hangs.

How do I also remove the messages for a fresh 'factory' start ? Is it enough to remove the folder holding them (~/.local/share/local-mail/) ?

Migrating from kmail to thunderbird

2

I like the kmail interface, but I've had problems with it for years and in the last few days it has become unusable: it keeps locking up or crashing and there's no solution on the 'net. I won't go into details as I'm sick of it.

I tried reseting its settings (https://forum.kde.org/viewtopic.php?f=20&t=97754) to no avail. I want to move Thunderbird, but I haven't found a way to import the messages/accounts/filters: In Thunderbid the [Tools][Import] then [Next] brings me to an empty window with only [Cancel]. From kmail I managed to export everything to a zip export file, but I don't know what to do with it.

I searched for import add-ons for thunderbird without success. I've read some messages that say to move the /cur/ directories manually but that's only for the messages, right ? Any advice ?

Compose key problem on one KDE system

2

I have several Kubuntu systems, configured the same way, where I have enabled the compose key (I write in multiple languages), but the upgrade to 15.10 on one of those systems broke my compose key.

Specifically it still works in Firefox, Thunderbird (but sometimes with a lag, if I type too fast it won't work).

It doesn't work in Kate, Konsole, OpenOffice, Dolphin, System Monitor... Specifically if I try to compose 2 characters, it will sometimes display both and sometimes swallow the 1st one, never composing them.

How to make KDE remember your opened windows across sessions?

6

This used to work on Kubuntu 14, 13, etc... but since the upgrade to Kubuntu 15.04, after I login only some of my windows re-open automatically. And some of those that do are not in the position I left them. And they are all on the first desktop (I use 4). Even those set to [All desktop].

Also the Konsole reopens with only one tab and it's forgotten the last path.

So, I've checked that:

[Restore previous session] is set in [System Settings][Startup and shutdown][Desktop session], I even did it manually
there isn't any funny business in the windows [More actions][Special windows settings][Size and position]

Am I missing some option, or is there a bug somewhere ? The fact that they all end up on the 1st desktop leads me to think of the latter.

kubuntu 15.04 upgrade: many problems

2

I'll just toss here a list of problems I have with the recent upgrade to kubuntu 15.04

I'll accept that all my settings are gone because of the change of framework 4 to 5 (it would have been nice to get a big fat warning about it, or better an update/transfer method), but during the upgrade process I was asked if I wanted to keep LightDM or use the new SDDM. I chose the former, but still the latter was installed and causes problems (how do I switch between them ?)

In particular I now cannot unlock a locked screen: after I type my password, it blacks out briefly then comes back to the login screen. I can't start a new session either. After I reboot I get a crash screen about a sddm-greeter crash. Also there's no [Off]/[Reboot] buttons on the login screen.

Once logged in, if I try to log out or reboot I get plenty of crash window for various kde and sddm components and can't cleanly logout/reboot.

Something else very annoying: there's no more console in Ctrl-Alt-F2 and others. Just a black screen. Typing login/passwd blind doesn't work.

Cat/baby keyboard protection

2

is there a way to automatically lock the keyboard (preferably without locking the computer) when several keys are pressed together or held for long, similar to a cat walking on the keyboard or a baby having a fit at your lack of attention towards him...?

I know I can have a shortcut key to start the screensaver, but I'd rather the screen stayed on while I wrestle the little monster to the ground...

How to perform a HP BIOS upgrade with only Ubuntu?

17

I have a HP Spectre XT netbook. The installed BIOS is F14 and the latest one on their website is F26. I'd like to do an upgrade but they only provide a Windows executable. I tried booting with FreeDOS (using the Ultimate Boot CD), but the executable won't run in DOS, only Windows. I don't want to install Windows anywhere (I don't have it, I replaced it off the system disk with Ubuntu). So how can I upgrade with only Ubuntu installed on my system ? I haven't tried Wine, does it work for that purpose ?

Why is it being held ? What is holding it ? Note: other custom usb cards work fine. This one is old though, so could it be a USB1/1.1/2 issue ? I disabled USB 2.0 EHCI temporarily in my VM, but no change.

More info:

$ sudo udevadm info -q path -n /dev/bus/usb/002/029

Udevadm info starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.
