No desktop notification when changing volume via keyboard

Konjad

When I change volume level via keyboard multimedia keys the volume changes, however there is no notification that actually shows it, so if I don’t listen to anything at that moment I have no idea how much the volume changed, which is annoying and I keep changing it constantly because I don’t know how much I already changed it. I’d like a notification, a bar like when you change brightness for example.

There has been a bug report on this for years, first reported in 2012. It appears that nothing has been done since then:

https://bugs.launchpad.net/ubuntu/+source/lubuntu-meta/+bug/1005542

You could add to the report that it affects you.

4 years… yeah, Linux software has a great support from its own developers 🙄

Is there any workaround? Different software that works?

Dennis N

If you are willing to switch to a different Ubuntu “flavor” then you would have the notifications. As an example, I use Xubuntu, have a multimedia keyboard, and the dedicated volume up/down and mute keys show a volume level popup notification when used.

You could try installing xfce4-notifyd. It works in Lubuntu.

It’s a bug in Unity with a dual, or multi-head set-up: https://bugs.launchpad.net/ubuntu/+source/unity/+bug/1602901

Automatic kernal updates no longer come

Wadcutter

I’m baffled by the Linux kernals.

My wife and I both run Ubuntu 12.04 on desktop computers. We both get regular OS, application and security updates, but my computer also receives automatic Linux kernal updates, but her computer has stopped receiving them. I’m currently at 3.2.0.98 while she has stalled at 3.2.0.94.

Even before her kernal updates (upgrades?) stopped coming, she always lagged receiving them by several days behind my receipt of them. Don’t know why.

I’m a bit wary of messing with kernals, so I would like to find some solid info on how to get her back on track for receiving the updates regularly before I start tweaking things. She did receive 3.2.0.95 a few months ago, but it was somehow corrupted and her graphics were out of whack. I restored her to 3.2.0.94 and that is where she has been ever since.

Searching other posts for info before adding my request make me wonder if I should be careful about what I am asking for. There seems to be a history of all kinds of mischief being caused by the automatic kernal updates. Maybe I should leave her computer alone (since it’s working fine) and instead try to disable the kernal updates on mine? Dunno.

Thank you.

If it ain’t broke , don’t fix it. Is good advice.

Have you ever heard of phased updates? This explains it.

https://wiki.ubuntu.com/PhasedUpdates

I have 2 installs of 16.04 development version on the same machine and they both have a different kernel version. It is strange but true.

Giving an entirely new version of any widely used software program to our entire user base all at once is unnecessarily fraught with peril.

Instead, let’s employ a phased update strategy wherein we provide the updated software to an ever-expanding set of random users. This pool of users will be grown as our confidence of that software update grows, fed by realtime information from the crash database and other potential sources.

This process will be developed in tandem with the efforts to increase testing of packages in -proposed so that we have more confidence in the updates we are pushing out. This process will add to that the ability to pull an update before a large number of users encounter it.

If a kernel upgrade seems to break the system we can go into Advanced options for Ubuntu at the Grub boot menu and select an previous kernel. And then there might be an update a few days later that fixes the problem. There is no need to remove the new kernel.

If you run

sudo apt-get update
sudo apt-get upgrade

You may see a list of packages being held back. It may include a kernel upgrade. These packages are held back for a reason but they will be installed eventually.

Regards

Wadcutter

Thanks for your time to explain things. It makes perfect sense. Something interrupted the download of kernal ver 95 and, I believe, corrupted it. The next time she booted, the graphics were frozen into a very low resolution. I did what you mention by going back into Grub and rolling her back to ver 94. I did, however, delete 95 because I though it now had bugs in it caused by the interrupted download. No further updates have come since then (Approx November 20, 2015). i tried what you suggested above, but it only needed to upgrade rsync–no mention of kernals. I think we are OK with things the way they are. We will probably both be upgrading to a more recent version of Ubuntu soon and that will probably take care of this (and create a whole host of new issues to deal with) Thanks, again.

How do I get rid of “Network/Browse Network” in the left side pane of caja?

894532185610544562

I don’t get it, why is there windows settings when I have my network already configured in NM? I’ve been in caja’s settings and I can’t seem to find a way to uncheck it. For the mate panels however, in the “advanced mate menu” you can change it by going into its preferences -> places -> unchecking network. And that gets rid of the location in the menu…it’s still showing in caja view.

Display not working

skinner927

I have a remote machine running 14.04.1 Desktop x64 kernel 3.19.0-51-generic. Everything’s updated as far as apt is concerned.

Recently the display has stopped working. I do have automatic updates so perhaps an update screwed something up, but it could be a hardware failure, I’m unsure how to determine either.
This is a kiosk machine at my parents house (it’s a picture frame) and they’re only going to make things worse if I try to get them to open the box so I have to do everything remotely (plus I’m 5 hours away).

I can ssh into the box. I’ve tried VNC with vino and I only get a blank screen. I’ve since turned it off for fear it could be creating it’s own issues.

From photos they’ve sent it seem the screen is completely off. No backlight. I don’t know if there’s blinking cursor in the corner because the picture frame cuts of the top and bottom of the screen (neat, I know).

They’re telling me they only get the BIOS POST and then the screen goes black. So it doesn’t appear to be a hardware failure.

~/.xsession-errors is empty

I tired installing xbacklight to see if the backlight was the issue. xbacklight says: Cannot open display “”

Most screen related programs are spitting out similar. I cant seem to find where to start with this issue. How do I, I guess, attempt to reattach a screen? Not sure that’s the correct terminology.

Here’s output from lshw. It seems the screen is identified, but possibly not being used? Any ideas? I can run anything you’d like. Thanks in advance!

Thumbnails when uploading photos

bab5470

I frequently upload photos to various sites. I’ve noticed since switching from windows to ubuntu the file browser in my web browser doesn’t allow me to preview a thumbnail of each photo.

I can only see one preview at a time. For example here’s Opera on Linux:

270992

And here’s Opera on Windows:

270991

Notice that I can see multiple large thumbnails at once so I can more easily select which photo I want to upload from a group of photos.

Is there some way to enable this functionality on ubuntu? Maybe a different web browser or a different file manager?

Thanks,
Brad

clock applet on panel does not show weather

iokara08

Hello Ubuntu users,

I am using Ubuntu 16.04 64 bit. During the last 20 days I have noticed that the clock applet on my top panel does not showing the weather. Does anyone know a solution?

have a nice afternoon.
——
ian-weisser

Clock applet showing the weather is not installed by default.
So when you installed it, what was it’s name in Software Center?

iokara08

Hi ian-weisser, I haven’t installed any additional application, I just set my location under ”locations” in the ”Clock applet” which is located by default at the right side of my top panel in Ubuntu Mate desktop.

The issue remains but I will mark this thread as solved since I found out that I can use ”My-Weather-Indicator” which I installed through Ubuntu software center and it works fine.

Thank you for your reply.

ian-weisser

“Ubuntu Mate Desktop” is different from “Ubuntu 16.04 64 bit”
The latter does not have any weather app installed by default.

Glad you found a solution that works for you.
Next time, you will get better and faster useful help if the description of your system is accurate.

XRDP – Can’t launch System Monitor, Chrome or Vuze(Azureus)

spiritofcat

I’ve been running 12.04 for a number of years, using it as a torrent downloading and media server machine, serving a bunch of external hard drives to my local network to be accessed by windows machines and android devices.

I’ve just installed XRDP in the hope of being able to operate the machine remotely. I’ve followed guides on Griffon’s IT Library, and managed to be able to connect on Unity, xfce4, or lxde.
However, while I can connect and operate most programs normally, I can’t get System Monitor, Chrome or Vuze to launch in any of them.
Firefox works, and Thunderbird works, but Chrome is my preferred browser, and it’s not much use as a torrent downloading machine if I can’t access Vuze.

Any ideas?

Don’t know if this has any impact on the situation, but the computer is still logged in and running both Vuze and Chrome locally. Perhaps they can’t be run in two different sessions at the same time?

Is there a way to connect to the existing session on that machine instead of starting a new one for XRDP?

Edit: Just checked on the computer physically and I found a whole heap of chrome windows open, and system monitor too.
Looks like my attempts to launch worked, but they appeared on the physical session, not the remote one…?

Tried logging out and leaving the computer sitting at the login prompt, then connecting with XRDP and that seems to have solved the problem.

I’d really like to be able to keep that computer logged in though, and access the same session remotely. Is that possible?

Edit: Looks like vino might offer the functionality I’m looking for.
I’m about to follow the tutorial here: http://ubuntuwiki.net/index.php/Xrdp,_installing

Edit: Yep, Vino does the job! Problem solved.

16.04 kde applications have no icons in fluxbox

Wellconnected

Dear all,
I’m using kde5 in 16.04 and trying to go back to my nice old fluxbox setup.
I’m surprised to see that kde apps (korganizer/doplhin) run from fluxbox have practically no icons,
whereas gtk apps seem to be fine.

Any ideas where to start debugging this?

Thanks,

Hardware Stats for DE

Blackbug

Is there any application which can log the hardware stats for the DE. I want to compare the stats esp. cpu, battery drain, fan usage, ram for a session and then can generate some kind of graphs and compare with other DE’s.

I know psensor but it doesn’t record battery drain. I am not sure if any such app though.
——
mastablasta

why would fans speed be depndent on DE?

htop for CPU, RAM

powerstat, powertop for battery
http://askubuntu.com/questions/73904/how-do-i-monitor-power-consumption

note that the problem with so many apps is that they each measure in a different way. IMO if you take a terminal app (that doesn’t actually depend on gtk, qt etc.) and use it in all DE you should get comparable results.

there are also services for server that can run and logs status. so you can see changes over time. for example like collectd

have a look at this comprehensive list if you can find something good. most will not do the battery usage. :
