Chromium is installed as a snap. When it's running, how do I kill the process from command line? Like killall or pkill. This didn't work:
sudo snap stop chromium
error: snap "chromium" has no services
With two USB sound cards (presonus audiobox and behringer xenyx q802) I have crackling sound after the kernel was updated to 5.13.0-37. Tried on three different machines with Ubuntu 20.04 and 21.10. Audio output from onboard audio is ok. Output from USB sound card has irregular peaks (faster than every second).
I found this:
Upgrading to 5.13.0-37-generic breaks audio with external audio card
which is very interesting, but doesn't tell what to do to get it working again. I have no older kernels I could revert to. Any suggestions?
I mean, these were updates also for a LTS version that are not supposed to break a working system?
From Scribus 1.4.2 on, Scribus should find previously installed dictionaries while installing and be able to use them. With version 1.5.5 from the repository this doesn't seem to work. Although different dictionaries have been installed via LibreOffice, the option from the menu "Extras/Check Spelling" only shows "English (US)". Furthermore I can't find an option within Scribus to install additional dictionaries.
I use three installations on three computers, all of them Ubuntu 20.04. On one of them I can select from all installed dictionaries, on the two others there's only "English (US)".
Hunspell is not installed on any of the three.
apt-cache policy hunspell
hunspell:
Installed: (none)
What am I missing here?
I want to install a HP DesignJet Z6100 (not Z6100PS) on Ubuntu 20.04
The driver provided by hplip is for the postscript version of the printer: Z6100PS. If I use it, the printer replies "error 61:01 - wrong file format". Probably the driver sends postscript data.
I tried to install a ppd file I found online at the University of Delaware. Now the printer shows up as "DesignJet Z6100" (not Z6100PS), but trying to print I get the same error.
According to wikipedia a ppd should show up here /usr/share/ppd/ or there /usr/share/cups/model/
but there is nothing new.
Wikipedia also states
CUPS uses PPD drivers for all of its PostScript printers, and has even extended the concept to allow for PostScript printing to non-PostScript printing devices, by directing output through a CUPS filter.
So I figured it might be possible to use that printer on Linux even if there is no driver. Is it? How do you make a ppd? Anything concerning groups and permissions? (user is in lpadmin)
what I also tried:
lpinfo -v: does see it:
network dnssd://HP%20Designjet%20Z6100%2042in%20Photo%20%5B9D6B69%5D._pdl-datastream._tcp.local
I can access the printer via the web interface.
But: HP Device Manager doesn't detect it via Ethernet. Printer has no USB.
In Ubuntu settings, there are options for the handling of removable media, for example to select what happens if one puts a CD into its drive. Inside there's a list of different software to choose from. Some programs installed as snap do show up, others don't. fre:ac isn't in the list. Is there a way to select it for starting automatically on CD-in-drive?
I have a cifs/smb share mounted in fstab.
With Libreoffice: when attempting to open an *.odt from there it takes a good minute to happen. A *.doc opens instantanously, as does an *.odt from a local drive.
Kubuntu 19.10
Has anyone experienced the same and maybe resolved it?
On professionally pressed Audio-CDs the ISRC (International Standard Recording Code) identifies any recorded track with 12 digits (like this: ATP811301008) It's usually not part of the CD-Text that contains artist, title etc. One can read it with cd-info (part of libcdio-utils)
The data from CD-Text is used by Rhythmbox, Sound Juicer or k3b to fill the ID3 tags (or they get the data from cddb or MusicBrainz or something).
Is there any software in ubuntu repositories to achieve that?
I'm running Ubuntu 18.04 on a Surface Pro 2, and nearly everything works out of the box.
But: the single most annoying thing is a notification about something not working with the touchpad. It appears most of the time I click on left or right touchpad button.
This is the notification. It's being displayed for 2 seconds.
With 16.04, a similar notification was shown as one of those bubbles in the upper right corner, it wasn't that much in the way then. In fact the touchpad is working mostly. Right click doesn't work in shell. Hä?
Does anybody have an idea how to get rid of this, or better still, make the touchpad work? Thank you.
If I install software as a flatpak app, to use it I have to start it from the shell like this flatpak run org.name.appname
How do I add an icon for that to ubuntu dock? I can make a script like that:
#!/bin/bash
flatpak run org.audacityteam.Audacity
but then, how do I add this shell script to dock?
with Ubuntu 14.04 and 16.04 it was easy to send hpgl data to my Roland vinyl cutter. I connected the plotter via usb, let cups install the plotter automatically, chose "raw queue" and sent the data from the inkscape extension "inkcut 1.0".
With Ubuntu 17.10 and CUPS 2.2.4 there is now "raw queue" printing option any more. I've tried several others like text only, pcl and what not, but with no success. The communication with the plotter works, but with "text only" it cuts the vinyl to random slices - that's what it looks like to me. Other than that I get various errors on the plotter.
I know that Inkcut 1.0 is really old, but I don't know of any alternatives. Does anybody have an idea how to send hpgl paths with a recent cups, ideally from a gui like inkcut?
Many thanks, especially because the vinyl-cutting-on-linux-community seems not to be that big.
With Ubuntu 17.10 (artful aardvark):
when trying to calibrate my monitor with my datacolor spyder 3 calibration tool using the settings - devices - color manager, after I am told to hang the instrument on the screen and start calibrating I get something like
an internal error occurred that could not be recovered - remove calibration device
does anbybody know what to do here? Thanks. minyves
EDIT:
Found it! It worked after
apt-get install colord-sensor-argyll
