I've noticed that apt estimates the upgrade to take 48.1MB more space on upgrading from 62.0.3202.94-0ubuntu0.16.04.1317 to 63.0.3239.84-0ubuntu0.16.04.1. I've skimmed through apt changelog chromium-browser and don't see anything that's described as taking much more space. Is there a quick way to see what files changed with apt or anyone who knows or will find the reason?

$ apt list --upgradable
chromium-browser/xenial-updates,xenial-security 63.0.3239.84-0ubuntu0.16.04.1 amd64 [upgradable from: 62.0.3202.94-0ubuntu0.16.04.1317]

I've tried to install the latest Intel Graphics but it fails to find i915-4.3.3-4.2.0-dkms. Is their GPG key expired or wrong or is that a problem on my side somehow?

For a while now when I switch between two user sessions the inactive one in some cases will stop executing GUI processes. This way I'm forced waiting for another session to load and can't do something in another one, because if I switch and return after a while it's still on the same point. The software affected includes rsync, rdiff-backup, KDE background processes, Steam launched in Openbox session (even downloading stops) and at least some games. VLC is not affected, at least it skips to needed time after I switch back, but for a moment I can see old frame and time in it's window.

What process is responsible for such behaviour? Can I reconfigure it somehow?

Update: Memory and Swap Usage

Some additional context: The irony is I suggested this exact behaviour on the old brainstorm.ubuntu.com (now defunct).

I want to execute a script on headphones disconnect but I resent the idea of constant polling of the status when there is already some code executed when it's changed.

I've installed intel-microcode=2.20140913.1ubuntu2 but I'm still getting 2014-05-29 loaded according to

dmesg | head -n1

Do I have to use iucode-tool?

I've installed ubuntu-sdk and it depends among others on mediascanner2.0. I generally despise all such scanners/trackers and I'd like to disable it. But I can't find a way.

The config is in /usr/share/upstart/sessions/mediascanner-2.0.conf

All the info about TLP on the surface looks more like advertisement and marketing to me, I can't see any detailed comparison to default configurations. What are the precise differences compared to default (K/L)Ubuntu installs under the hood, are they really effective?

Update: And if they really are, why aren't they a part of a default config?

apt-get install build-essential:i386 doesn't work at all:

The following packages have unmet dependencies:
 build-essential:i386 : Depends: gcc:i386 (>= 4:4.4.3) but it is not going to be installed
                        Depends: g++:i386 (>= 4:4.4.3) but it is not going to be installed

Note the 14.04 tag. Answers on Trouble compiling a 32 bit binary on a 64 bit machine are outdated. Also, there are no ./configure script to use the Compile 32 bit on 64 bitsystem answer.

I'm trying to complite DFHack from quietust branch: https://github.com/quietust/dfhack/

apt-get install gcc-multilib g++-multilib removed the

CMake Error at depends/protobuf/CMakeLists.txt:60 (MESSAGE):
  Could not find a working hash map implementation.  Please install GCC >=
  4.4, and all necessary 32-bit C++ development libraries.

message, but

-- Could NOT find Threads (missing:  Threads_FOUND) 
Can't locate XML/LibXML.pm in @INC (you may need to install the XML::LibXML module) (@INC contains: /etc/perl /usr/local/lib/perl/5.18.2 /usr/local/share/perl/5.18.2 /usr/lib/perl5 /usr/share/perl5 /usr/lib/perl/5.18 /usr/share/perl/5.18 /usr/local/lib/site_perl .) at xml/list.pl line 6.

is still there. Do I have to manually seek all i386 build-essential the dependencies?

I just tried installing Intel(R) Graphics Installer 1.0.5 for Linux* from https://01.org/linuxgraphics/downloads and it installed ttf-ancient-fonts. Any ideas on why do they need it?

Related forum topic is https://01.org/linuxgraphics/node/331 but I don't want to register there yet.

I've deleted ~/.macromedia and ~/.adobe contents and after a restart chromium can't detect flash plugin. It works just fine in Firefox

I have only "Chromoting Viewer" on chrome://plugins/

chromium-browser 34.0.1847.116-0ubuntu2
adobe-flashplugin 11.2.202.350-0trusty1

I have profile-sync-daemon active (tried stopping it, of course) and broken PolicyKit as in NetworkManager broken after upgrade to Kubuntu Saucy

Does the detection depend on PolicyKit? What else can I do?

There are no examples in the manual and every file I've tried needs some geometry.

$ xkbcomp /usr/share/X11/xkb/symbols/ua tmp/ua.xkm

$ xkbprint tmp/ua.xkm
Cannot open "tmp/ua.xkm" to read geometry

$ xkbprint /usr/share/X11/xkb/symbols/ua
Error: Couldn't read geometry from XKM file "/usr/share/X11/xkb/symbols/ua"
Exiting

I have this message in syslog and dmesg output:

r8169 0000:03:00.0: can't disable ASPM; OS doesn't have ASPM control

Is it a configuration problem or hardware issue?

Over time I gathered more than 10 launchpad bug reports that were reported with apport, initially marked as private and never responded to.

There was one I've discussed additionally on IRC and that's the only one I can remember being processed.

What should I do with them? How can I make sure they don't contain anything really private before making those bugs public?

There is a keyboard with ' key broken. I've remapped it to the Wake button with xmodmap but that affects only X session, how can I achieve this for TTYs?

Note: editing keymap files directly is not the best option since I want the system to be upgradeable.

I've checked the wiki but Xorg is not even mentioned there.

Is there a DE-independent utility to show all windows beside each other in more lightweight DEs like Openbox, LXDE or Xfce?

Something like this:

I've added the Qt5 Daily repository, installed the qt5-meta-full and added /opt/qt5/bin/qmake to Qt Versions. Now I get

:-1: error: Unknown module(s) in QT: declarative

Is it possible yet to use Qt5 with Qt Creator?

I'm trying to add vte widget in my application and the examples I've found use .fork_command() to execute a command in that widget. But according to

http://developer.gnome.org/vte/0.26/VteTerminal.html#vte-terminal-fork-command

it was deprecated and it's recommended to use fork_command_full(). Which needs eight mandatory arguments. Haven't they heard the "defaults" word? I've been able to construct lines that work somehow:

pty_flags = vte.PtyFlags(0)
terminal.fork_command_full(pty_flags, "/home/int", ("/bin/bash", ), "", 0, None, None)

Yes, I know about the enums, I just hope that I'm doing this completely wrong and there is a much easier way. Do you know any?

P.S. I'm using quickly with the default ubuntu-application template.

P.P.S. The import line is from gi.repository import Vte as vte

My friend had problems with touchscreen (they are gone after two reboots) after her sister used her laptop and when I tried to help I didn't find a way to identify /dev/input/* files. One way I've found was to grep in $ dmesg (/var/log/kern.log) but it doesn't work for me.

Does any standard method exist?

I've read the Upstart features and it says nothing about concurrency. I also read old advices to set CONCURRENCY value in the /etc/init.d/rc But there is a comment:

Specify method used to enable concurrent init.d scripts. Valid options are 'none', 'startpar' and 'makefile'. To enable the concurrent boot option, the init.d script order must allow for concurrency. This is not the case with the default boot sequence in Debian as of 2008-01-20. Before enabling concurrency, one need to check the sequence values of all boot scripts, and make sure only scripts that can be started in parallel have the same sequence number, and that a scripts dependencies have a earlier sequence number. See the insserv package for a away to reorder the boot automatically to allow this.

And the CONCURRENCY is set to none.

insserv is installed in my Ubuntu 11.04. But is it used?

My system is already amazingly fast because it's on the SSD. But I'd like to know if it uses all cores during boot.
