I have a multi-button mouse. I can change the order of the buttons, for example so the left swaps with the right, using:
xinput set-button-map "Mouse Name" 3 2 1 4
When I press the 4th button once, I want it to be interpreted as a double click on the left button.
What's the modern way to achieve that?
Is there any way to see or configure Ubuntu's Power Delivery options?
One of my USB-C chargers doesn't provide sufficient power to my laptop.
I've tried different PD USB-C cables of different lengths. They all exhibit the same issue, but only on this specific laptop.
I can run:
$ upower -i /org/freedesktop/UPower/devices/battery_BAT0
To see how long the battery will take to charge, but I can't see how much power is being delivered.
Is there any way to see or configure what my laptop is negotiating?
I've recently upgraded to 17.10. When I try to browse to a website, or ping a domain it fails saying the site cannot be resolved.
network-admin shows the contents of /etc/resolv.conf to be nameserver: 127.0.0.53
If I change that to 8.8.8.8 or 208.67.222.222 then everything works. Until I reboot.
Upon reboot or resume, the nameserver is reset to 127.0.0.53.
How do I permanently set the nameserver to something that works?
For systemd fans, if I run systemd-resolve --status I get
Link 3 (wlo1)
Current Scopes: LLMNR/IPv4 LLMNR/IPv6
LLMNR setting: yes
MulticastDNS setting: no
DNSSEC setting: no
DNSSEC supported: no
If I follow the advice at this question - DNS keeps resetting after reboot. Ubuntu 17.10 - DNS still fails to resolve.
How do I compile opus-tools to use Opus 1.2.1?
I've manually installed the latest version of Opus
wget https://archive.mozilla.org/pub/opus/opus-1.2.1.tar.gz
tar -xzf opus-1.2.1.tar.gz
cd opus-1.2.1
./configure
make
sudo make install
That completes without error and, I assume, means the 1.2.1 library is now installed.
I then try to compile opus tools:
wget https://archive.mozilla.org/pub/opus/opus-tools-0.1.10.tar.gz
tar -xzf opus-tools-0.1.10.tar.gz
cd opus-tools-0.1.10
./configure
make
I now have opusenc and the other tools compiled in that directory. However, when I run ./opusenc --version I see
opusenc opus-tools 0.1.10 (using libopus 1.1.2)
What magic command to I need to use in order to get opusenc compiled with 1.2.1?
I have a zip which contains files with very long names.
If I try to extract on the command line, I get the error "File name too long".
If I use the graphical archive manager it will not extract the files and it will not let me rename them. The same problem occurs if I mount the archive.
I can extract and rename files individually using:
unzip -p -c example.zip "long file name.ogg" > shortname.ogg
This is impractical with lots of files.
Is there a tool which will truncate filenames as they are extracted?
I have a Bluetooth "Camera Shutter" dongle. It emulates a Bluetooth keyboard. I've paired successfully, but I want to change how the buttons behave.
Currently, they're mapped to 123 (Volume Up) and 36 (Enter).
I'd like to change their mappings - but only for this Bluetooth keyboard. I want my laptop's keyboard to be unaffected.
My end goal is to have a Python program run when one of the keys is pressed.
Some things I found which didn't work:
setxkbmap.xkb seems to remap keys on all keyboards.xinput can remap mouse buttons but not keyboard keys.I want to press "Volume Up" on my external keyboard and have a command run - without interfering with my internal keyboard's "Volume Up" key.
Any ideas? Ubuntu 14.04.4 LTS. Thanks.
Is there any way to get Unicode Fitzpatrick Skin Tone modifiers working in Ubuntu?
For example, using U+1F3FD ( ? - http://graphemica.com/%F0%9F%8F%BD ) I should be able to modify the skin tone of an emoji.
So ?? should render as something like 
- instead, I see ? ?
I've installed Microsoft's seguiemj.ttf as recommended but the colour changes don't seem to work - even in Firefox.
I have a Universal 3D File - but I cannot find any way to view or convert it in Linux.
Here's what I've tried:
If the file is embedded in a PDF, I can view it using Adobe Reader 9 - but there's no way to export it.
Ideally I'd like to be able to convert it to STL - but any common 3D format would do.
Has anyone found or built a converter?
I need libav version 10 or higher. I'm running Ubuntu 14.0.3. I have versions 9.18-6 installed.
Looking at https://libav.org/download/ - I see some source files I could try to compile - but I'd rather not mess around with that.
Is there a PPA or .deb for the latest version?
I'm trying to mount a remote WebDAV (OwnCloud) using https on my Ubuntu 12.04 machine.
I run this command and it prompts me for a username and password
sudo mount -t davfs -o uid=ne,gid=users https://example/owncloud/remote.php/webdav/ /mount/remote
I then get the error
/sbin/mount.davfs: Mounting failed. SSL handshake failed: SSL error: sslv3 alert handshake failure
Other machines (including Android) are able to connect to the WebDAVS correctly.
How can I prevent this error? The certificate is signed by CloudFlare, if that makes a difference - but that doesn't seem to cause a problem for any other systems accessing the OwnCloud instance.

I've tried updating to the latest libneon but that hasn't made a difference.
Since upgrading to the latest OpenSSL, I now get a different error
SSL handshake failed: SSL alert received: Handshake failed
As suggested elsewhere, running openssl s_client -host example.com -port 443 -ssl3 returns:
Verify return code: 0 (ok)
I've compiled and installed libneon 30.1
./configure --prefix=/usr --enable-shared --with-ssl=openssl --disable-static
but the error persists.
I have a CD image which is in .cdr format. (Please note, it's not the same as a Corel Draw image - which also uses the .CDR extension).
Is there any way to open it on Ubuntu? I don't have a local CD drive - I just want to extract the contents to my HDD.
It won't open with Brasero, I can't mount it, nor extract it from the file manager.
Is there any way to convert it to a standard ISO?
I'm trying to compile some software on Ubuntu 12.04 (64 bit). It fails with this error.
checking for make... /usr/bin/make
configure: tested: whether version of /usr/bin/make is 3.82+
configure: ===INF=== Installed version of make is not 3.82+:
make: *** No targets specified and no makefile found. Stop.
Checking
$ make --version
GNU Make 3.81
This program built for x86_64-pc-linux-gnu
I downloaded 3.82 from http://ftp.gnu.org/gnu/make/ ... then ran:
./configure
sudo make install
make --version
GNU Make 3.82
But, I'm still getting the above error message.
Is there any way I can ensure this is the only version of make on my system? Or a way I can install a higher version of make 3.X?
I've installed Gnome Flashback (Compiz) because I need window control buttons on the right hand side.
Really, the only thing I'm missing is a dash / lens. I'd like to be able to press the "Super" key, type "firef", hit enter, and have Firefox launch.
Is there any plugin I can use?
I read that Unity 2D could do this - but it doesn't seem to be included in 14.04
Is it possible to view 3D models with PDF documents?
There are a number of PDFs which contain detailed 3D models such as this example: http://www.carare.eu/eng/content/download/2718/21413/version/1/file/Macellum_at_Pompeii.pdf
The models are viewable in Windows and OSX but I can't find any way to view them in Ubuntu.
I've tried evince but it doesn't work.
I'm running Ubuntu 12.04 on a MacBook air - everything works fine, apart from the fact that the screen dims after 60 seconds of activity. Is there any way to stop this?
My computer is on mains power. If I stop using the machine, after 30 seconds the keyboard backlight turns off (that's fine). After a minute, the screen dims by about 50% - this is annoying, especially when watching a video or reading a long page of text.
My "brightness and lock" settings seem fine:
I've tried
gsettings set org.gnome.settings-daemon.plugins.power idle-dim-time 600
But that doesn't make a difference - it still dims after 60 seconds, no matter what value I set it to.
I've also used gconf-editor but I don't appear to have /apps/gnome-power-manager/backlight
I'm not using Unity - just the standard Gnome desktop.
Is there any way to change this behaviour? I never want my screen to dim. I'm quite happy controlling it manually with the F1 and F2 keys.
EDIT
No - Caffeine doesn't work. The screen still dims.
No - changing the DPMS doesn't work.
No - Editing stuff in dconf doesn't work.
No - I don't have any other power manager software installed.
