Brother HL-L2350DW | Linux | Ubuntu base

I'm using this printer under Ubuntu (Kubuntu) 18.10.

I've tried installing it via Ubuntu itself (USB connection > Let Ubuntu/Printer find the recommended driver, and use that). Sometimes it have printed, but most of the time not. Was able to print a few pages from Thunderbird and Kate (.txt) yesterday, but then not print a .pdf from Okular. And now it's completely dead again.

The printer throws me error messages like:

• Rendering page 3. (In Printer settings/queue)
• Processing page 2. (In Printer settings/queue)
• Sending to printer (In Printer settings/queue)
• Unable to add document to print job. (In Printer settings/queue)
• Out of memory. (On printer LCD)

I've tried both the Local Printer (USB) and Network Printer, where I've tried all drivers pertaining to the printer, as suggested by Ubuntu and those I've found myself:

• Recommended Drivers > Brother HL-L2350DW series, driverless, cups-filters 1.21.3
• Brother > HLL2350DW for CUPS (en)
• Generic Text-Only Printer (en)

I've even tried to install the drivers from Brother's website (.deb package).

§ dpkg -l | grep Brother

ii  printer-driver-brlaser    4-1         amd64        printer driver for (some) Brother laser printers
ii  printer-driver-ptouch     1.4.2-3     amd64        printer driver Brother P-touch label printers

Further, I have to log in* on the CUPS interface for my printer.

Depending on the connection type you are using (USB or Network), follow one of the steps below.

(for USB Connection)

1. Open a web browser and go to "http://localhost:631/printers".

2. Check if the Device URI of your printer is "usb://Brother/(your printer's model name)"

   • If the device URI is different from the example above, please go to "Modify Printer" of your printer to select proper device and driver.
   • If your printer is not listed on "http://localhost:631/printers", please go to "http://localhost:631/admin" and click "Add printer" and select proper device and driver.

In here I can't find anywhere to check, and/or correct, the Device URI.

Any ideas or similar experiences? This is gettin really frustrating, to put it mildly.

*Log-in information is the same as your user account on your PC. I.e. Finally stumbled upon that information when writing this here post, so this here is for anyone scratching their heads bloody over log-in info, as I did.

Is there an "easy" way of changing the label/name/mount of a LUKS encrypted HDD, and at the same time have it mount at a Label name in /media/user/ ?

Atm I have my disk listed twice in Dolhpin:

1. 3,6 TiB Encrypted Drive
2. 3,6 TiB Hard Drive)

and mounted under a name like

(/media/user/)g976g98j-34f6-45hg-45g342346

The disk is at

sdb ---sdb1 ---luks-da123qwe-123asd-123zxc-123qwerty /media/user/123qwe-123asd-123zxc-123qwerty

TL;DR:

• LUKS encrypted HDD.
• Name it (e.g. Label)
• Have it mount at /media/user/Label instead of /random-alpha-numeric
• Have it show in Dolphin as Label
• A way not involving having to muck about with things that'll kill my system :/ Looking at you, fstab.

System: Kubuntu 17.10

PS:

By some stroke of luck, I have previously been able to get another drive to remember the label I put in during formatting (KDE Partition Manager). It mounts at /media/user/Label and is shown as such in Dolphin. Alas, I have no idea how I managed it. Lots or re-formatting, labeling, rebooting, etc. I suspect it's actually some sort of bug...

Trying to install VeraCrypt on a new install og Kubuntu 17.10. However I'm having some trouble.

Running the veracrypt-1.21-setup-gui-x64 file (double click -> execute), extracted from archive (verified sha512 and GPG), produce this output in the terminal it opens:

Verifying archive integrity...  100%   All good.
Uncompressing VeraCrypt 1.21 Installer  100%  
Unknown option 'caption'.
Press Return to close this window...

Tried instead running the file in bash (from some article "how to install VC)

sudo bash veracrypt-1.21-setup-gui-x64 

Produced this:

-------------> ~/Downloads/veracrypt-1.21-setup 
USER - > sudo bash veracrypt-1.20-setup-gui-x64 
Verifying archive integrity...  100%   All good.
Uncompressing VeraCrypt 1.20 Installer  100%  
QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-root'
QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-root'
Unknown option 'caption'.

I also tried install veracrypt-1.20, if the fault was with 1.21, but no luck.

I have no idea what any of that means. On 17.04 I installed VC no problem.

Has it something to do with me installing Flatpak (for Steam)? XDG rings a bell as some "older" name for Flatpak, iirc.

Any ideas as to what's wrong here?

I found a Sourceforuge thread about the same issue, but no answers.

I just installed Kubuntu 17.10 (reinstall, from 17.04), keeping my old /home, but formatting/reinstall to /boot and /

When it started up after installing, I noticed the sound icon in tray being the "speaker + red line", indicating no sound. Systray Sound Icon > Dropdown say:

no output or input devices found

In Settings, I can't change anything related to audio since the system claims there's nothing there. Settings > Multimedia > Audio Volume. No ouput/input device found.

Strangely enough, Spotify and VLC is making sounds. But not Firefox, not Pillars of Eternity (Steam (Flatpak)). And nothing show up in settings. Those pics were taken while playing music in Spotify.

If I open Volume Control (Menu > Multimedia > PulseAudio Volume Control), I get a box displaying the following message:

Connection to PulseAudio failed. Automatic retry in 5s. In this case this is likely because PULSE_SERVER in the Environment/X11 Root Window Properties or default-server in client.conf is misconfigures. The situation can also arise when PulseAudio crashed and left stale details in the X11 Root Window. If this is the case, then PulseAudio should autospawn again, or if this is not configured you should run start-pulseaudio-x11 manually.

These was no countdown (5s), but the window did blink twice to something to the effect of "trying to connect to PulseAudio". Nothing happend after that.

I tried start-pulseaudio-x11. Output:

Connection failure: Connection refused
pa_context_connect() failed: Connection refused

My sound device is connected via standard Jack (normal speakers). No HDMI or anything. Two monitors connected via DP. Had no problems with it on 17.04.

I tried the following, from an old question: mv ~/.pulse ~/.pulse_backup

Result: mv: cannot stat '/home/USER/.pulse': No such file or directory

TL;DR: Audio doesn't work after installing Kubuntu 17.10 (/home from 17.04). No settings available in audio Settings. Sound from VLC and Spotify, but not Firefox, game/steam. Error message say PulseAudio failed.
