Abiword constant flicking at the top of the screen.


Hello all,

I’ve installed Lubuntu 16.04 on an old computer and noticed that when I load up abiword I get constant flickering at the top of the screen. This only happens when Abiword is open, nothing else in Lubuntu is affected. Has anyone else seen this, if so, is there a fix for it?

Thanks in advance!!

Ubuntu 14 LTS – Terminal occasionally doesn’t flush most recent lines


This is a weird problem I’ve been having for a while now, occasionally I will type something in Ubuntu like a command to git and I don’t see all the lines of output immediately. In other words it looks like the process has hanged but that’s never the case. Instead what has happened is the output isn’t appearing in the terminal, like it isn’t flushed. git is just one example it happens randomly with different commands.

For example right now I’m bisecting in git, and I typed that I bisect was bad so I see
$ git bisect bad
Bisecting: 13 revisions left to test after this (roughly 4 steps)

But it doesn’t show the actual text that comes after that even though the command is already done, it just appears to hang. So I can hit enter and it will show me whatever wasn’t flushed. That should be unnecessary though. Any ideas?

Problem with XRDP – possible memory leak?


Hello, i have a problem which i’m trying to resolve during the past few days without any success. I’m using Ubuntu 14.04 on my home server. The server has 16gb of ram. I am using it mainly as a Kodi player (attached to my TV), so the main desktop environment which is on all the time is the Kodi player. For the rest – maintenance etc – I connect to the server through XRDP connection from my laptop (running windows 7) or from my desktop pc (running windows 10). Recently i noticed that something is eating up all the available memory. After checking it turned out that the X11RDP session is taking up to 12-13gb of ram – an incredible amount! After a restart X11RDP is taking about 100mb of ram, but after a few days it eventually fills up all the available memory, which forces me to restart the server to be able to use it. Can someone help me to identify the problem?

firefox error messages on kubuntu 16.04


Firefox sometimes locks up completly for minutes and often outputs lots of error messages. I am not sure the issues are related, but I do observe repeated error messages like the following appaearing in the console from which I started firefox:

(plugin-container:5056): GLib-GIO-ERROR **: Settings schema ‘com.canonical.desktop.interface’ is not installed

[32258] WARNING: pipe error (69): Connection reset by peer: file /build/firefox-01C0AB/firefox-46.0+build5/ipc/chromium/src/chrome/common/ipc_channel_posix.cc, line 459

Does anybody know what I can do about these error message?

I think that the “locking up” issue may be related to pages containing flash. Not sure however because firefox does issue any warning about unsupported plugins.

Unity, 16.04, menu change in top panel is slowwww


I’ve been a gnome-shell user for years, but am strongly considering switching to Unity. All was looking good…but…

If I have 2 or more full-size windows running, and switch between the two, the top panel is VERY slow in updating the menu to the new window that’s on top. As in 5-10 seconds, or more. Seems odd.


A quick update.

The top panel shows the correct menu when:
– I switch windows using alt-tab
– I switch windows by selecting the top window via clicking on the icon in the launcher
– if I set window behavior to “appearance->behavior=in menu bar”

So it appears, my problem only occurs when using a hot-corner to view and select a particular window.
Still, I love using a hot-corner to select a window, and can’t come to using Unity if I can’t find a fix for this.

It’s extremely frustrating to have a full size window on top, and not have access to its menu!


Anyone? This is kind of a show stopper for me for Unity. I can move a window to the top, work in it for 10s of seconds, put my mouse over the panel, and the panel will STILL show the menu for the previous window.

Settings are :
Under Settings/Appearance
-Show the menus for a window: In the window’s title bar (this is needed because I use GIMP, and GIMP doesn’t seem integrated into Unity)
-Menus Visibility: Always displayed
Under Window Manager/Additional
-Focus Mode: Mouse

Such a basic thing to ask Unity to do..show the right window menu!


Can’t replicate your problem but there were a few reported issues with menus during the 16.04 development cycle.

May be worth looking at this thread.. http://ubuntuforums.org/showthread.php?t=2319736

PS. Right clicking in the GIMP image window will give you access to the menus, not a solution, just offering as a workaround.


Thanks for trying to replicate!

If I set menus for a window to ‘in the menu bar’ and menus visibility to ‘display on mouse hovering’, all works as it should. Setting GIMP to single window mode makes that work ok too…..
All windows managers / desktops have their nuances I guess. 🙂

Gnome 3.20 PPA ?


Gnome just announced the public availability of Gnome 3.20 beta. Their official release date is March 23.
I know I can build it, but I was wondering if there is a PPA for Gnome 3.20?
Frogs Hair

The Gnome3 team PPA is up to 3.18 . Ubuntu is usually behind the latest Gnome version due to release dates, so a Gnome 3.20 PPA will likely show up after 16.04 is released.

Evolution “mail received” sound


I’m running a couple of different systems, one based on Ubuntu Precise uses Evolution 3.2.3. When mail comes in, I get an audible notification. On my newer system, running a distribution based on Ubuntu Xenial, the installed version of Evolution is and I get no audible notification when mail is received. I’d like to turn this feature on in the newer system. How can this be done?

I’ts all done with evolution-plugins.


Have you gone through the configuration of the plugin ?

Edit > Plugins > Configuration.


Yes. As I note above, I solved the problem myself. The Evolution plugins weren’t loaded.


Ah ok, sorry 🙂

Misread post two as meaning something else. Glad you sussed it.

No problem 🙂 Thanks for writing back with the fix anyway/

Plasma calendar weekend highlight


Can’t get a calendar widget to display weekends (Sat+Sun) in a different manner than workdays. I’d like to have an alternative background color or highlight days in any other way (digit color, border etc).
Holidays and current day are highlighted well (via borders).

Here is the default Digital Clock / Calendar look (same as mine):

Desktop Menus Broken On Upgrade From 14.04 -> 16.04



I upgraded my desktop running Ubuntu + LXDE (Lubuntu session) tonight and it seems to have broken my menus. The menu button is empty (other than the Logout and Run entries) and if I try to add a launcher button to the panel it fails to generate an application list. I also tried running Alacarte to edit the menus but get the following error:

/usr/share/alacarte/Alacarte/MainWindow.py:22: PyGIWarning: GMenu was imported without specifying a version first. Use gi.require_version(‘GMenu’, ‘3.0’) before import to ensure that the right version gets loaded.

If I login with a test user things seem to work fine, so it seems to just be a problem with something in my user settings. Does anyone know how to diagnose this other than “delete .local and .config and start from scratch”?

Just replying to myself in case anyone else runs into this issue. The problem seems to be that the desktop menus changed from the l- prefix to lxde-. To fix it edit ~/.config/lxsession/Lubuntu/desktop.conf and change menu_prefix=l- to menu_prefix=lxde- in the [Environment] block.
