#StackBounty: #linux #ubuntu #sftp #sublime-text-3 #lubuntu SublimeText fails to save file over sftp after apparent timeout

Bounty: 50

I am running lubuntu in a VirtualBox. In my file manager (PCManFM-Qt) I navigate to

sftp://myusername@myremotehost:/mydirectory

and open myfile.txt with SublimeText. I can edit and save this file without problems.

However, after some time passes (or for example after putting the machine to sleep), whenever I try to save I am greeted with the error:

Unable to save /run/user/1000/gvfs/sftp:host=myremotehost,user=myusername/mydirectory/myfile.txt
Error: No such file or directory

which does not seem to go away until after I restart the entire system. I cannot even re-open the file or any other file from the remote host into SublimeText; instead SublimeText just opens a blank file called "sftp".

I can still open these files with any other text editor on my system (such as gedit and notepadqq) so the problem seems to be with SublimeText.

Is there a fix for this?

#StackBounty: #boot #lubuntu boot stuck on "load/save rf kill switch status"

Bounty: 50

I recently tried to install lubuntu on an old computer. After a successful install I installed updates however and restarted. But when the computer booted again I saw only a black screen.

After following the instructions here:
My computer boots to a black screen, what options do I have to fix it?
I edited grub menu to start OS with nomodeset.

The problem is that now while booting the computer is stuck on
[OK] started load/save RF kill switch status

The computer is an inspiron mini 1018

Any ideas?

#StackBounty: #usb #android #usb-storage #lubuntu Lost USB access to my Samsung GS6 phone

Bounty: 50

All other devices on my Lubuntu 20.04LTS system hotplug fine, with a message asking if I want to open the device in my file manager. However, as of yesterday, I have lost this when I plug in my Android Samsung GS6 phones. Normally, I’m prompted to "Allow" the connection (on the phone) then if I select "Yes" it will open the file manager prompt. Now, all that happens (on two phones) is that the "charging" indicator comes on.

I have tried the following things and identified that this is an issue with the Lubuntu 20.04LTS system:

  1. Tried phone 1 with different cable (no dice).
  2. Tried phone 2 with same cable (no dice).
  3. Tried phone 2 with different cable (no dice).
  4. Plugged in USB flash drive (works fine).
  5. Plugged phones into Lubuntu 20.04LTS laptop (works fine).
  6. Turned off system (as opposed to reboot) and restarted (no dice).
  7. Tried dialing *#0808# and selecting (then reselecting) MTP – ADB
  8. Ran "lsusb" and can see the phone is recognized: "Bus 001 Device 017: ID 04e8:6860 Samsung Electronics Co., Ltd Galaxy series, misc. (MTP mode)"
  9. Here is the appropriate "dmesg" output:
[45269.216369] usb 1-11: new high-speed USB device number 18 using xhci_hcd
[45269.366168] usb 1-11: New USB device found, idVendor=04e8, idProduct=6860, bcdDevice= 4.00
[45269.366173] usb 1-11: New USB device strings: Mfr=1, Product=2, SerialNumber=3

[45269.366182] usb 1-11: SerialNumber: 04157df4a262a410

I have a feeling that either a recent update (the system has been updating frequently) OR my own fiddling while trying to get a USB connection to a DSLR. (Installed v4l2loopback, gphoto2, etc.) I would greatly appreciate any help in getting this working again.

#StackBounty: #lubuntu #display #brightness #redshift #f.lux F.lux or redshift and lubuntu issues

Bounty: 50

I’m a noob. Putting this out there right away. Using Lubuntu 19

I want a blue light filter. So I’ve installed f.lux, but when I adjusted the brightness on my laptop it toggles or flashes between the screen without f.lux and then back to f.lux as I increased or lowered brightness. So I uninstalled f.lux and reinstalled it. Now it doesn’t work at all.

As for Redshift, when I change the brightness it automatically just switches back to the brightness level that redshift has assigned. This is quite different then how it acts on other operating systems where you can lower or increase the brightness yet keep the effect of redshift–which is all I want. Can anyone help, or should I just install Ubuntu?

#StackBounty: #networking #drivers #wireless #lubuntu #20.04 Lubuntu 20.04 wifi intermittent problem

Bounty: 50

I have an issue with the wifi in a HP 15-db0598sa that I’ve installed lubuntu 20.04 on.

Pinging google.com gives typical output of the form:

where the ping varies from ~10ms (as on my other machines) up to > 1000 ms, with the odd ping (about 24% packet loss) dropped (such as between 172 and 175 and 179 and 181 above).

The output of lspci -knn | grep Net -A3 is as follows:

I have disabled IPv6 on the dhcp as in this answer: https://askubuntu.com/a/1180403/489692

In furtherance to DESGUA’s answer, I changed /etc/dhcp/dhclient.conf. More specifically, I deleted line 18:

dhcp6.name-servers, dhcp6.domain-search, dhcp6.fqdn, dhcp6.sntp-servers,

I eventually disconnected wifi and reconnected.

and that ameliorated some issues, but the ping is still intermittently ~10ms and >1000ms.

Are there any other configuration settings I could use to improve the stability of the connection (besides using wired networking – this laptop will be in a different room to the router so this is possible, but I’d prefer to use the wireless).

To add: I’ve got an older machine using Ubuntu 18.04 in the same location, and the ping there is fine:

EDIT: I have tried installing the driver here (for RTL8723DE) https://github.com/lwfinger/rtlwifi_new/tree/extended
and the output of lspci -knn | grep Net -A3 remains:

so it looks like the new drive hasn’t installed. I’m at a complete loss now

#StackBounty: #lubuntu #language #spell-checking #abiword Add Spellcheck Dictionary to Abiword 3.0

Bounty: 50

I am working on Lubuntu 14.04 with Abiword 3.0.0 and with the pre-installed version only the spell-check for English came along. I can switch to other languages within the program, but then the spell-checking isn’t working.

I checked different forums, but didn’t find a straightforward solution. I downloaded the ispell “hash” files (+encoding file) for French and German. But now I don’t know where (in which folder location) to put them or how to use or properly install them. The location info from this help page doesn’t seem to correspond anymore (http://www.abisource.com/help/en-US/info/infospelling.html)

But maybe that’s also not the way to go and I can achieve spell-checking of these languages in a different way. How could this be solved?

#StackBounty: #server #lubuntu #suspend #power-management #amd-processor System refuses to suspend

Bounty: 100

Lubuntu 18.04 (lxde) here, upon AMD Epyc 7282. Kernel 4.15.
The system is stable and works flawlessly, but id does refuse to suspend.

If I try to suspend it, the screen blanks, but the system does not power off.

At this point, if I hit a key or move the mouse, nothing happens. If I hit the power button, the system “wakes up”, presenting the login screen, and then all the applications as I left them.

Hibernation is absent alltogether.

Note that Epyc Rome is not affected by the notorious RDRAND bug which affects Ryzen 3000 and causes problems with suspend to ram.

EDIT: I used the system for days with high load, and can confirm rock stability, but if I leave it blanking the monitor, there is no way to wake it up.. One has to connect via ssh and reset the system.

Can you help me?

#StackBounty: #lubuntu #bluetooth #18.10 #lxqt Bluetooth connection (Bluez) not working after logout (works after restart)

Bounty: 50

I use LXQT in Lubuntu 18.10 and I have a problem with keeping the Bluetooth-speaker connected to the laptop after logging out and in. It works fine after reboot though.

So, I have a solution that always works: rebooting – OR: reinstalling bluez:

sudo apt-get install --reinstall bluez

and that always works!

In any case, when my problem happens, the bluetooth is never blocked.

If I reboot or reinstall bluez there is no need to remove and add again the device, setting it to “Audio sink” is enough.


When this happens, after logging out and in:

  • The speaker is listed by blueman-manager, setting to ‘Audio Sink’ brings the error Protocol Not available.

Which aspect in the normal operation of bluez – one that is available at system startup as well as by reinstalling the package – could be lost by restarting the session? – And how to avoid that loss?


UPDATE/EDIT by the OP:

[I am the OP. At some point I have deleted my account and then I came back with the same id.] I want to add that this is a Lubuntu-LXQt-specific problem. I have seen this problem in many Ubuntu and Ubuntu-based distros before 18.04, but in none since 18.x. Since 18.04 it is fixed excepting in Lubuntu-LXQt.
