We just bought a Lenovo ThinkPad E570 (which is supposed to have the Intel 8265 for wireless). This laptop was bought in part because it is certified to run Ubuntu and as such to me at least it would make sense for things to work out of the box... but no such luck.

First, I installed Ubuntu 17.10 and after installation realised Wi-Fi was not working. I also tried Ubuntu 16.04 from a USB drive since that is the version of Ubuntu it is certified for, but no luck there either.

The wireless chip is not detected by lshw (or even lspci by the looks of it), ip link does not show a wireless interface, and the iwlwifi kernel module is not loaded at boot (I can load this myself using modprobe iwlwifi but this does not make Wi-Fi work). I think it is a combined Wi-Fi/Bluetooth chip, and Bluetooth does appear to work (or at least Bluetooth shows up in Gnome and rfkill list).

modinfo iwlwifi | grep 8265 shows me a file ending in -34 is supposedly loaded but only a file ending in -33 (and some other lower numbers) is present in /lib/firmware, if that helps).

I have also installed the Linux 4.14.9 kernel in an attempt to get things to work, but this did not resolve the issue either.

Update

I just noticed that the laptop does not have an Intel wireless chip at all, but in fact has a Realtek one... which means that the specs presented on the product page of the shop I bought this laptop at were not accurate... Sigh. Same problem stands, however, just with a crappier wireless chip.

Our stereo installation supports, according to the box, streaming over AirPlay (although the normal RAOP stuff doesn't seem to work on it. I think it's something called Airport Express), DLNA and Windows Media Sharing.

On Ubuntu, it seems almost impossible to get this thing to work, while on Windows it's possible with iTunes and Airfoil.

What I've tried, and what went wrong

• Airplay: Streaming over PulseAudio
  • Music players refuse to play. Status changes to playing, but the search bar thingy and the position counter don't progress. No sound comes out of either the stereo installation or the computer. I've also tried to manually create a "Sink" (?) using pactl load-module module-raop-sink server=192.168.1.32. The result was the same.
• Airplay: Stream2IP
  • I'm guessing this uses the same backend as the Pulseaudio thing, or perhaps even does exactly the same. It says it's connected, but exactly the same happens as did with the previous method. The stereo installation doesn't even recognise any kind of connection. It just continues playing what it's already playing.
• DLNA: Stream2IP
  • When I go to Media Server on the stereo installation, it sees RobinJ: Root. Music, Browse Files, ... all go on to a screen saying <Empty>.
• DLNA: Serviio
  • This actually seems to work fine. The free version is limited, and it's not open source, but at least it allows me basic streaming features. However, what I'd prefer is for audio from a specific applicattion, or if possible the whole system, to get streamed to the stereo installation. Rather than me having to browse through menu's on the stereo to choose a song.
• Windows Media Sharing: Nothing
  • I have no idea how to do this on Ubuntu.

Does anyone have any suggestions? Don't just close this as an "Exact duplicate", because if I haven't found an answer after looking for half a year, I think it's safe to assume that the answer is not yet on this website.

I'm running Ubuntu 13.04, but I don't mind switching to 12.04 or 12.10, or even en different distro, if it'll work there.

I can't get Quickly to upload my project into my PPA. I've set up my PGP key and used it so sign the code of conduct, and the PPA exists. I don't know what other usefull information I can supply.

quickly tutorial Result: An empty Yelp window with the XML file opened in gedit.

yelp /usr/share/quickly/templates/ubuntu-application/help/tutorial.xml --> Exactly the same problem.

Worked fine a few days ago.

Manually changing the file association of XML files to Yelp (which I actually don't want to do, because all other XML files should open in gedit), and then running the command again gets my system into an infinite loop.

I'm having some trouble with Python, again. I created a project using Quickly, and it created a preferences dialog for me. I am now trying to build up the preferences dialog, but I always get some error pointing me at a piece of code Quickly generated itself.

The pangolin has struck again. The bug of the day for today is Ubuntu taking away my permissions on my Data partition (NTFS). One moment everything worked fine, the next moment I couldn't chmod anything anymore. chown throws no errors or warnings at all, but nothing has changed either. chmod keeps saying Operation not permitted.

I've been messing around with /etc/fstab as suggested by other answers on AskUbuntu, but none of them seem to have the desired effect.

This is my current line:

UUID=25D7D681409A96B7 /media/Data     ntfs    defaults,umask=000,gid=46,permissions,users,auto,exec 0       0

For reference, this is the original one:

UUID=25D7D681409A96B7 /media/Data     ntfs    defaults,umask=007,gid=46 0       0

(right after the problem started occuring)

What do I need to do so I am the owner of my own hard drive again? I want to be able to just use chmod and chown (without sudo) without being told that some mysterious alien has taken over control of my Data partition.

I can still read and write, but execution permissions seem to be the problem.

--

I already figured out the execution permissions problem. The bounty's for the one who can tell me how I can set myself as owner of the data on that partition.

Currently, when my button's label gets more characters, its container boxes resize horizontally, and push away the other containers next to it. I don't want this behaviour.
How do I give my boxes a fixed width, so that they don't get resized anymore when their child widgets get bigger?

Not sure if this is a bug or just a very annoying feature, but I can't get an image to appear on any of my buttons in Glade Designer.

Is there some property I need to change in order to force it to display the image?

I just installed the Plex media server from the Ubuntu Software Center, and opened the web interface. I wanted to start by adding a collection. When it gave me a file browser, I wanted to go to /home/robin/Videos. /home is as far as I got. It showed robin, with an arrow in front of it, but when I tried to expand the directory tree it was empty. The same happened when trying to access /media/Data. For me it's quite useless like this, as all of my media files are inside those 2 directories.

Help would be much appreciated.

My first guess seemed to be a correct one; It is, as always, a permissions problem. How do I give plex access to my home folder without also giving other users access to it? My home folder is encrypted by the way, so that'll probably complicate things a little.

robin@RobinJ:~$ sudo -u plex bash
[sudo] password for robin: 
bash: /home/robin/.bashrc: Permission denied
plex@RobinJ:~$ ls -al
ls: cannot open directory .: Permission denied
plex@RobinJ:~$ cd /home

bash: cd: robin: Permission denied
plex@RobinJ:/home$ ls -al robin
ls: cannot open directory robin: Permission denied

I needed GPartEd to format a MicroSD card (don't trust Disk Utility too much as more problems seem to occur with hard drives and memory cards I formatted with it, than with the ones I formatted wth GPartEd), and almost got a heart attack... There's a damaged partition on my new hard drive (a bit more than 2 months old)!
Luckily it was only my SWAP partition, but still...

I'd like to know a few things...

• How to rule out the possibility of hardware failure.
• How this can happen if the problem's not hardware-related.
  • I only installed Linux once on this computer (waited for Ubuntu 12.04 to get released), so it's not a SWAP partition that remains from an earlier installation.
• What can be the cause of physical hard drive damage.
  • The computer hasn't fallen of a desk or anything...
• How to prevent this in future, if at all possible.
• Additional: Whether it's normal that reading (and writing as well, I think) speed drops significantly over a minute time; and if it's not, what are some possible ways to analyse/fix the issue?

No problem if you can't answer all of my questions.

Information

It's a read-only benchmark.
The partition labeled Windows holds a Windows 7 installation I'm supposed to need some time for school, and I used before Ubuntu 12.04 got released. I have booted it up a few times after Ubuntu 12.04 was installed (I don't know whether Windows' disk check can do any harm to Linux partitions, but it always seems to run a checkdisk after I changed my partition table layout with a Linux application like GPartEd).
/dev/sda7 is the SWAP partition I'm talking about.

I guess my best option now is just try to boot a Live CD and format /dev/sda7 again? It won't format it from my installed Ubuntu system.

I'm trying to make an app to switch your XFCE4-Panel's layout between 3 layouts. I applied those layouts and copied the XML file where Xfconf stores its configuration for the panel.
The general idea was that I could just remove the old file and copy over the new one. Only, that didn't work out so well. Something appears to be preventing me from changing the XML files without the use of xfconf-query. I could just reset the panels every time, let the script set the values to how they should be, and restart the panel, but the configuration files are a bit big to do all that (I'm also experiencing a few problems with the content of the panel when using xfconf-query).

So basically I want to know if there's a way to just apply the configuration of the whole XML file. Whether it's by killing some processes and quickly copying the files over, or by using something that automatically parses the XML file and sets all the values with xfconf-query. I'm using Python (combined with Bash) if someone knows some kind of class that can do it.

I'm trying to customize a LiveCD, but I can't manage to fit it on a normal CD. So I investigated, and came across a few files of which I don't know if it's safe to remove them.

Maybe you can help me there?
I don't care if the files get recreated every time, as I remove them just before I start packing everything into a new ISO. So it'll still save me some space.

The files:

• /var/cache/apt-xapian-index/index.1/postlist.DB
  • This file seems pretty useless to me, and it keeps growing every time. It's now at a 38MB, while I could have sworn it was only 27MB the last time I checked.
• /var/cache/apt-xapian-index/index.1/termlist.DB
  • Same story as postlist.DB.
• The files in /var/lib/apt/lists/
  • Seems to me that those are cached files which get automatically recreated when you run apt-get update, is this correct? I don't really dare to remove them unless I'm sure in case I break something. All those files together are about 50MB.
• /boot/initrd.img-3.0.0-12-generic
  • I'm not at all sure of this one... But doesn't this file get automatically created when the user installs the system to his hard drive? I thought the initrd.lz file in the casper directory inside the ISO already contained the initrd stuff to boot the liveCD.
• /var/cache/debconf/templates.dat
  • Doesn't this automatically get recreated when some runs apt-get update?
• The rest of the files inside /var/cache/apt-xapian-index/index.1
  • Aren't they all cache files which automatically get recreated?

You don't have to tell me about all the files in one answer. But if you know one or more of them, I'd be grateful if you told me.

In Windows my dad used to have a program called MP3 Tunes. I have tried running it with Wine, and it worked. But strange things kept happening to the program, so it's not a reliable way to play music.

Basically I just want to have 2 players (in a single window) with these features:

• Preloading tracks in a player without immediately starting them.
• Fading from one track to the other.
• A timer on each player.

These features are also desired, but not required:

• Microphone input.
• Prelistening before loading a song in a player (through a seperate sound card).
• Pitch/Tempo control.
• Just being able to browse folders in the filesystem (without things like a music library).

Here are some screenshots of the program to clarify what I'm looking for:

I am having problems with Adobe Flash in Ubuntu, what are my options?

My MP3 player plays files in the order they have been placed onto the filesystem. Now it seems to Nautilus copies files in some random order, so when listening to an audio book or something I get all the chapters in random order, wich isn't so great when your on a bicycle so you can't take your MP3 player out of your pocket to find the right one. When using mc (Midnight Commander) most files are copies in alphabetical order, and that's the way I want it to happen.

So is there...

• any way to tell Nautilus to copy files and folders in alphabetical order?
• a program wich can sort the files and folders in alphabetical order directly on the filesystem?

Additional information:

• Elementary OS 0.1 Jupiter (based on Ubuntu 10.10)
• 64-bits
• Copying music over from an NTFS filesystem to a strangely formed FAT32 filesystem on the MP3 player.

I have only used my external hard drive once, wich was with my previous Ubuntu installation (11.04), on the same laptop. I have created 2 partitions, FAT32 and EXT4. Now I needed to get some data from my external hard drive and IT WOULD NOT LET ME. No matter what I do in Nautilus, it will not do a thing with it. It is NOT corrupted. When I do mount /dev/sdb1 /media/sdb1 in a terminal, it said Permissions denied... (SO IT WON'T ALLOW ME TO ACCESS MY OWN DATA??). When mounting it as root, it works, but I don't want to. Things should simply work, normal users don't want to dive into a command line and go edit text files to do a simple action like mounting an external hard drive, and neither do I. When mounting it as root, by the way, and running sudo chown robin /media/sdb1 it even sais Permission denied, while I am running the command as root! Frankly, I'm getting sick of things like this. Any way to fix this for once and forever? No solutions please that I'll have to apply every time I reinstall Ubuntu on my laptop or anything like that. I am a user, I want to use. Not dive into command lines and text files for the simplest possible actions.

--Edit--
Just to clarify, I've got no problems with typing a few commands in a terminal windows, as long as that solved the problem permanently. I don't want to have to go through a mess like this on every computer or every time I reinstall my OS.

I know there something called fancontrol, that enables you to control the speed of your system's ventilation. I'd like to let my fans spin a bit faster as my laptop is heating up very easilly. All tutorials and stuff I've found are for old versions of Ubuntu and don't seem to be working anymore.

Can anyone explain to me or give me a good link on how I can get it working on Ubuntu? Something different with the same effect is also fine.

I just booted up my laptop and opened up my webbrowser. I went to OMG! Ubuntu!, and wanted to scroll as I always do, with the right side of my laptop's touchpad... It did not work... I went to the Control Center to check if the option was still enabled... And after going through all of the options in the Control Center, I must come to a conclusion... The option has been removed!

Can anyone tell me why this usefull function has been removed and how to turn it back on again somehow? Preferably just having the option back and working in the correct dialog. This one option made touchpad navigation 10 times easier in Ubuntu than it was in Windows... and now it appears they have removed it...

PLEASE!!! I BEG YOU!!!! *cough*

2 reboots fixed it for some strange reason...

I installed Ubuntu 11.04 on 2 laptops today. One of a friend, and one of my own. Both have NVidia graphics cards.

This went the same on both computers. When you login the first time you get a message wich is basically telling you to install the NVidia drivers.

However, when I restarted after installing the new driver on my friend's laptop, Unity just worked.

When I installed the drivers on my laptop, and rebooted, it just booted straight back into the Ubuntu Classic desktop environment.

In the sessions list at the login screen, there are the following items: Ubuntu, Ubuntu Classic, Ubuntu Classic (no effects), User defined, Recovery console. I haven't touched this setting, as it seems to me that Ubuntu should be correct.
Appart from that when I login I still get the Ubuntu Classic environment (without the message telling me that Unity couldn't be started) When I run compiz --replace manually, I get the Unity interface... but it instantly freezes.

So why doesn't it start the Unity interface? My graphics card is an Nvidia Quadro NVS 110M, wich has always worked fluently with Compiz Fusion.

For some reason, I've got some graphical issues sometimes. Mostly with AbiWord, LibreOffice (and OpenOffice.org), and Wine applications. I've added some screenshots below t oclarify a bit. This is not a problem that recently popped up. As a matter of fact, I've always had it since Ubuntu 8.10, and there never came an update to fix it. I'm currently using Linux Mint 10 (based upon Ubuntu 10.10), but as I already said, that doesn't really say much as I'va also had this problem with Linux Mint 8, Ubuntu 8.10, Ubuntu 9.04, Ubuntu 9.10 and Ubuntu 10.04. It was never a big problem, as I rarely used any text processing programs. But recently, I'm starting to use them more and more, and it's really annoying being unable to work because of this problem. When I first open an application, everything looks normal, then after a while (when I highlight, click, ... an item) they'll suddenly screw up. This also happens when I move or resize the window. Sometimes when this happens, I can just minimize the window, and when i restore it, sometimes it will be gone (for a few seconds at least) or it will have changed positions. I'm using the nvidia-current graphics card driver. But I have also always had this problem on my old computer, wich used... I think nvidia-96.

Screenshots (I've done the blur myself, so that's not the issue, the problem is that blue crap)
