unable to modify top bar transaparency using activities configurator extension

acetech

The transparency of top bar in my Gnome shell 3.18.2 cant be varied through the activities configurator (version 44) gnome shell extension. There is no effect of the transparency slider on the transparency of the panel.
My system configuration is ubuntu gnome 16.04 LTS, with arc theme. The screen shots are attached for easy reference.

I have a different theme and it works fine for me on 16.04 + 3.18.4 + solid background colour. You might try upgrading gnome-shell and/or contacting the author if it’s conflicting with a particular theme, or it may just be that the transparency doesn’t work with background images.

acetech

Thank you. It works with the default theme, yes the transparency level varies. seems the problem is with Arc theme. But still with the option override user theme it doesn’t works with arc theme. Is it the problem with the theme or with the gnome-shell extension. Any workarounds to make it work with arc theme.

Use expo plugin …

When i drag something around on the screen, it doesn’t seem to refresh as you can see.. does the same with shift switcher.. if i goto a blank desktop, i have flickering on the edges of what-ever is on the desktop beside it, like overlapping etc..

Tired the normal compiz settings, unredirect etc… refresh rates etc.. zero difference.. any ideas.?

I’m seeing things as you describe with other apps and dual monitors with the same Nvidia Driver with nvidia-364 I did not see as much.
Just my 2 cents worth.

Plasma_NZ

Irony is… i was previously using NVIDIA-Linux-x86_64-361.42 – after reboot this issue appeared… only after not being able to fix it did i install NVIDIA-Linux-x86_64-367.27
where the problem still persists… removed compiz and all config files etc… same problem still.. so it was something between current kernel and previous where the problem started..

Plasma_NZ

effectively broken my desktop lol.. pushing 3 screens and 3 xsessions.. should never update.. lol

QDR06VV9

Yikes!! I am sorry to hear that.
By the way I may have some good news to ease your pain
Release: 15.04
Codename: vivid is no longer supported see this: https://wiki.ubuntu.com/Releases

Plasma_NZ

i have 15.10 – that has its own huge set of issues when using 3 xsessions across 3 screens… far more than 15.04… this single-screen supports killing ubuntu.
login loop that cannot be fixed when pushing 3 xsessions, keyboard across 3 xsessions – xev input for second k/m doesnt work properly etc.. list goes on lol – biggest issue is dpi on 3rd xsession thats different resolution that cant be changed cause xandr is blind to them and with no keyboard focus to other xsession results in unconfigurable..

QDR06VV9

My best OS I have run in quite a few Version’s is 14.04…smooth as cheese cake, everything just works well.
But that said everyone’s mileage may vary.
Yakkety is shaping up pretty nicely, but not relevant here.

Plasma_NZ

yeah, this is running flawlessly apart from this clipping issue… driving me mental lol.. if someones got a fix or patch or solution.. sing out..! lol

CantankRus

Did you use the Proprietary GPU Drivers ppa which can update other applications other than
the nvidia driver.
I only update the driver from this ppa.

Plasma_NZ

I use the ones provided by nvidia because with my setups they work best….. its a issue with the expo/wall plugin with something else…. changes have only happened with last kernel/files updates.. its not my drivers..

Just like to point out rickus… i made a new profile… everything runs smoothly…. untill i used tweak-tool to disable desktop icons/short-cuts – when i turned them off, instant pollution as the pic in original post showed… turned it back on… problem goes… dunno if this helps your case.. just something strange i thought..

Can you show the actual tweak tool settings you changed?

Can you show the actual tweak tool settings you changed?

It was gnome-tweak-tool – desktop – icons on desktop – set to on

If i set it to off, it cause huge clipping resulting in a kick back to login-screen

*.desktop file in Unity

ELMIT

I have a program: CAT.jar for which I made a C.A.T.desktop file:

[Desktop Entry]
Type=Application
Name=C.A.T.
Comment=C.A.T. Cryptocurrency Automatic Trader
Exec=java /home/ronald/C.A.T./CAT.jar
Icon=/home/ronald/C.A.T./cat-xxl.png
Terminal=false
Categories=Trading;Office;

I put C.A.T.desktop into the directory /home/ronald/C.A.T./

While the Exec statement is startable in a terminal, a click on that file in nautilus will not do anything.

What am I doing wrong?
——
CantankRus

Try as the Exec…

/usr/bin/java -jar ‘/home/ronald/C.A.T./CAT.jar’
Is the desktop file executable?

PS: .desktop files placed in ~/.local/share/applications will show in application menus like the unity dash.

ELMIT

I got one step further. When I click now on the destop icon I get:

The application launcher โ€œC.A.T.desktopโ€ has not been marked as trusted. If you do not know the source of this file, launching it may be unsafe.

chmod +x C.A.T.desktop helped ๐Ÿ˜‰

Recommended Way to Bring Back All System Tray Icons in Ubuntu 16

What’s the recommended way to bring back all system tray icons(whitelist) in Ubuntu 16 as separate icons not included in a dropdown?

What’s the recommended way to bring back all system tray icons(whitelist) in Ubuntu 16 as separate icons not included in a dropdown?
you may want to put your query into some sort of context/example as on the face it makes no sense..
systray/application icons are separate icons per app (no dropdown there) & work by clicking on to expose options (certainly a dropdown there

dannymichel

Notice skype and foobar on the top right system tray?
I had to install an app that allowed me to see them because Ubuntu hides them by default. I dont like how that app puts them in a dropdown. I’d rather something modify the default hiding behavior Ubuntu has for some really really odd reason has implemented.

Ubuntu moved to application indicators a couple of years ago & for the most part apps have created them in lieu of their systray icons.
I probably wouldn’t expect that from wine programs & a few others.

In that case to get individual icons you’d need to re-enable systray icons in the unity source & re-build the packages.
The change in source is quite simple, change 1 line of code & disable 1 compile time test. this is the patch I use here to do such in 16.04 –

You should try Gnome Shell, it has a beautiful way of showing those icons on a small auto-hide tray at the bottom of the screen. The rest of it is very elegant too (yes, I’m biased).

Battery Manager does not work.

I recently installed Xubuntu on my Surface 3. After ironing out most of the problems that come with installing on Microsoft’s tablet, I noticed that the xfce power manager doesn’t seem to recognize the battery. It always shows that it’s running on AC power, and it only shows a white plug for it’s notification tray icon. Is there a fix for this or should would I need to install another battery monitor.

Launcher advanced customization

I would like to remove the little shadow on the top of the launcher, between the dash and the title bar. On the folder /usr/share/unity/icons there is not an image for this. Compiz config settings manager and unity tweak tool don’t seem to have this option. That’s the only thing that remains for having a completely flat theme.

I mistakenly purged gsettings-desktop-schemas; how can I recover?

watchpocket

Here’s how things went from bad to worse:

I wanted to remove an item (an icon) on the Unity-greeter top panel. (The greeter is the only Unity thing I use). So I made some changes in one of the Unity-greeter config files, or lightdm config files (I forget which). This left me in low-graphics mode.

Then, I stupidly and quite mistakenly ran this command:

sudo apt-get purge gsettings-desktop-schemas && apt-get install gsettings-desktop-schemas

Then I watched tons of things being purged. Then I had no online connectivity, and still don’t, from my Ubuntu Mate 14.04 drive. I (also stupidly) appear to have no backup of my 14.04.

I can — from my Ubuntu Mate 16.04 disk — mount the drive that has 14.04 on it and access it that way. My question:

How can I:

(a) get back online;

(b) recover gsettings-desktop-schemas;

and (c) get lightdm/unity-greeter running back in graphics mode?

Would it make any sense for me to try to copy my 16.04 (or 12.04) “gsettings-desktop-schemas” over to the 14.04 system? (though I don’t know where to look for it).

I really seem to have wandered into no-man’s-land, & need to get on the right path. Any help appreciated.

Try checking /var/log/apt/history.log, it may hold some details. I am not sure if it will list all, like in CantankRus’ simulation, or just the package you removed. Hopefully that file will show some useful detail.

When you say “reinstall” — you mean reinstall the large group of programs that were purged, correct? Or do you mean reinstall a fresh Ubuntu Mate 14.04?

You can reinstall while keeping your home partition data.
Choose not to format in the installer.
Note your login name,computer name and login password and use the same when reinstalling.
The terminal prompt shows this.

So for anyone else who might accidentally do what I did here, I got things back under control this way:

After I’d entered the command that you should never invoke ( sudo purge gsettings-desktop-schemas ),

I got out of a black screen and onto the raw busybox command-prompt with . I logged in with username & password, then issued the following commands:
ifconfig -a
sudo dhclient eth0
That got my network connection working again. Then:

sudo apt-get install gsettings-desktop-schemas The latter command installed most, but not all, of what I needed.

So I opened /var/log/dpkg.log, weeded through it and found every single app, applet and library that had been purged, and painstakingly re-installed them all one by one.

Though most of them got installed with the sudo apt-get install gsettings-desktop-schemas command, I had no way of knowing which did or didn’t until I went to install them individually. Several important apps that I’d lost were only restored with the command to install that particular item. When I re-booted, I was more or less back to normal.

This all took about two-and-a-half hours.

Oh mother, tell your children
not to do what I have done

Thanks everyone who helped.

Different Wallpapers in Different Workspaces.. Why Not?

liberatio-spero

Hi Guys,

As a relatively inexperienced user I’m starting to find my way around 16.04.

It’s a very nice experience, but the only slightly annoying thing I’ve encountered so far is that while you can have 4 different work spaces to flick between, you can’t (natively) have different wall papers for each one (as a visual reminder as to which screen you are on).

Searching through the forums it seems this is common to most releases, not just 16.04, and a fix exists if you don’t mind downloading “tweaking” software and then not being able to have desktop icons ever again. I’m not really sure that’s a path I want to go down..

Does anyone else find this frustrating? Is there a reason it has never been changed (ie, technically somehow difficult to program or nobody else give a frig apart from me) ?

Is there a way to share requests/suggestions like this with the development teams? (like a Ubuntu “comments box”).. it would be a really great feature to have!

Depends on what you are using as a desktop environment. XFCE desktop allows different backgrounds (wallpaper images or solid color) on different workspaces.

mcduck

I’d assume the main reason is simply that the workspaces are handled by the window manager, while desktop (with it’s icons and wallpaper) is handled by the file manager (or something else), and there’s no standard mechanism for the two to talk about which virtual desktop you are looking at. This is also why you don’t get different desktop icons on different virtual desktops.

The only simple way around that is tighter integration between the window manager and whatever is dealing with the desktop (which some desktop environments have done), but doing so would also mean that you wouldn’t be able to switch those components to something else as easily.

For example I remember Compiz (the window manager) having a plugin for drawing different wallpapers for each desktop. However it wouldn’t be able to swap what the file manager (Nautilus or whatever you were using) was drawing on the desktop, and would only be able to draw a custom background image *behind* the file manager’s desktop window. Which basically meant that you had to switch off your file manager’s desktop to see the custom wallpapers, and so you lost the support for desktop icons and right-click menu…

edit: Also, Ubuntu uses Gnome’s file manager, Nautilus, and Gnome devs aren’t exactly known for their willingness to add new features… ๐Ÿ˜‰

liberatio-spero

I’m using the standard Ubuntu environment (Unity I guess).

Thanks for the detailed explanation.. I guess it’s a little more complex to incorporate than I imagined.

Too bad though.. hopefully it will appear in some future release.

Otherwise.. great user experience so far, thanks to all you guys here working on Ubuntu that keep this project going ๐Ÿ™‚

Hello and welcome, I have seen a few post on this topic but never try it my self you might find this post helpful http://askubuntu.com/questions/75998/is-it-possible-to-have-a-different-background-for-each-workspace I was trying to see if 16.04 would be on the list but it might be because it’s so new it’s worth a look

CantankRus

The process is fairly simple.
Install the compiz-plugins and compizconfig-settings-manager packages.
The compiz-plugins are not officially supported and a few of them don’t work.
The wallpaper plugin works in Xenial.
compizconfig-settings-manager allows you to configure compiz plugins.

Using the terminal….

sudo apt install compiz-plugins compizconfig-settings-manager

In the dash search for ccsm and open.
Enable the wallpaper plugin and set your 4 workspace pictures.
269339

You must also enable the JPEG and PNG plugins in “image loading”.
269340

As you stated earlier you won’t have desktop icons but with the unity dash and launcher you don’t need
to clutter your desktop with icons.

I use this script to randomly change the 4 desktops at a set interval.
It has been edited to keep workspace1 at the same image so you instantly know where you are.

Ubuntu 16.04 gdk-pixbuf issue “Unrecognized image file format”

bla-

Hello everyone,
I’m struggling with a gdk-pixbuf issue. Unity will segfault on start, I can manually start xfwm4. But GTK applications either crash or start without icons and many error messages such as “Gtk-WARNING **: Error loading theme icon ‘gtk-convert’ for stock: Unrecognized image file format”. Looking at the syslog reveal error messages such as “Oct 25 10:14:23 xxxxx gnome-session[29961]: (nm-applet:30339): Gtk-WARNING **: Error loading image ‘file:///usr/share/themes/Ambiance/gtk-3.0/assets/entry.png’: Unrecognized image file format
Oct 25 10:14:23 xxxxx gnome-session[29961]: (nm-applet:30339): Gtk-WARNING **: Error loading image ‘file:///usr/share/themes/Ambiance/gtk-3.0/assets/entry-disabled.png’: Unrecognized image file format”

The files are there and valid pngs. SVGs also do not work. I tried to reinstall gdk-pixbuf,libpng* but it didn’t help. I also tried to update the mime database and regenerate gdk-pixbuffer loaders.cache.
Any hint what might be wrong or how to debug this?
Thanks!
Jan

No real clue but if you’re mixing DE’s then generally a poor idea. Just to see what’s this report?

dpkg -l | grep libglib

I’m not mixing desktop enviroments, I normally run regular unity. Running xfwm4 was just a quick test to check if x is completely broken or if it is just unity.

Here is the output from dpkg:

Issue solved. Missing read permissions in /usr/share/mime. Was likely caused by a buggy closed source installer
