For some reason, Ambiance and Radiance themese (including Communitheme from PPA) appear broken in Ubuntu 18.04.
My installation is from when 18.04 was released and everything looked and worked fine until now.
Right now Ambiance theme looks like this;
Here's how settings window looks (notice the scrollbar on hover);
I tried reinstall light-themes as well as ubuntu-desktop package, but it doesn't help.
I have Ubuntu GNOME 17.04 installed along side Windows 10 on my HP Pavilion 15 AU113TX laptop. Sometimes when I switch to Ubuntu from Windows, I get distorted audio from left earphone while listening to anything.
This issue is intermittent as sometimes audio comes out just fine right after I booted to Ubuntu, however it starts causing problems again if I put Ubuntu to sleep and wake it up after couple of hours. On Windows 10, however, audio works perfectly even after reboots from Ubuntu or after waking up from sleep.
While I'm tagging 17.04 with the question, this issue occurred Ubuntu 16.10 as well, I haven't tried 16.04 though, since it originally shipped with Kernel 4.4 which doesn't have very good support for Kaby Lake chipset (which my laptop has).
I did go through Ubuntu's Audio Troubleshoot Guide but it didn't fix my problem. There are 3 related questions;
Unfortunately, none of those questions mention dual boot scenario and neither the solution they propose fix the problem.

I have recently bought HP Pavilion 15 AU113TX laptop, which comes with Intel Core i5 7200U Kaby Lake processor, I have installed Ubuntu GNOME 16.04.1 on it, and it is unable to detect WiFi adapter.
Upon running lspci -nnk | grep -A2, I'm getting following information about adapter.
028005:00.0 Network controller [0280]: Intel Corporation Device [8086:24fb] (rev 10)
DeviceName: Intel Dual BandWireless-AC 3168 802.11 ac 1x1 WiFi + BT 4.0 Combo Adapter
Subsystem: Intel Corporation Device [8086:2110]
But running rfkill list all, I see following output (WiFi missing there).
0: hci0: Bluetooth
Soft blocked: no
Hard blocked: no
And here's the output for dmesg | grep iwl.

Please note that this laptop is dual booted with Windows 10 Home, and WiFi is working fine there.
Now, I don't know if this adapter is supported by 4.4 kernel that Ubuntu 16.04 ships with, or it requires manual fix, as my laptop doesn't have hardware switch to turn on/off WiFi. Also, this being a combo adapter for both WiFi and Bluetooth, I can use Bluetooth just fine. Ethernet works too.
After searching around Intel® Dual Band Wireless-AC 3168 I found this page which suggests that support for this Wireless Adapter was added starting Kernel v4.6, and since 16.04 has Kernel 4.4, I tried two things.
1) Upgrade Kernel
I manually installed 4.7.3 from kernel.ubuntu.com, and booted into it but WiFi still remains undetected.
2) Loading firmware for this adapter version (3168).
I searched for .ucode files for this adapter and found it on OpenELEC's GitHub. So I copied iwlwifi-3168-21.ucode and iwlwifi-3168-22.ucode files to /lib/firmware/ and rebooted, but still no luck.
Update
This seems to be a linux-firmware related bug, and I have filed the report on Launchpad. However, workaround given by Jeremy31 seems to fix WiFi under Kernel 4.7.4, but it breaks Bluetooth which was working fine with Stock Kernel 4.4.0-38. I'm still looking for a proper fix which doesn't cause any regressions (I'm fine with upgrading to newer stable Kernel release).
I'm running Ubuntu 14.10, and for the past couple of days, I'm facing graphics stuttering all over Unity, which mainly affects text and various parts of Unity (refer to screenshot).
And this particularly happens when I'm using several apps simultaneously like, Chrome (latest), multiple tabs open in Terminal (running node-http-server). And only way I can fix it is by rebooting or by logging out (i.e. resetting Unity session).
Note that it is 5 year old laptop with 3 GB of RAM, 2.0 Ghz dual-core Intel processor, 512 MB of swap memory (using swapfile mounted as Swap memory in /), with only Intel on-board graphics.
What could be the possible cause? as I'm suspecting it is possibly due to low swap memory but this never occurred to me on 14.04.
Every time I try to open Ubuntu's (any version, since from 8.04 with which I started) default wallpaper, named warty-final-ubuntu.png, I get an error:
I reported this as a bug more than a year ago but it is still unresolved. Also I don't get why the default wallpaper is still named as warty-final-ubuntu.png instead of having actual code name prefix to which the wallpaper belongs eg. precise-final-ubuntu.png and so on.
I'm using USB 3G Dongle for Internet. Previously I was using Tata Docomo (India) as provider, and the Internet was working fine. Now I've changed to BSNL, but I'm unable to connect to the Internet on Ubuntu. However, I've checked access point settings and other configuration which are required for BSNL, and it is working fine with same Dongle on Windows 7. Also, I'm able to connect Internet with other providers on Ubuntu, but problem persists only with Ubuntu. The access point for BSNL in my region is bsnlnet. In fact I configure the Dongle with BSNL using default Network Configuration wizard that pops up when USB Dongle is attached.
When Dongle is attached and configured with BSNL, I can see network strength in Messaging menu, in Mobile Broadband category, of Ubuntu (note: my network icon still shows "not connected" status). And when I try to use the connection that I've created, it fails to connect. So far, I tried using Sakis3g script that I came up with while wandering over this issue on other forums, it didn't worked either. I also made sure that there are no special configuration made for BSNL on my Windows 7 installation, and still it is working fine there, the problem is only with Ubuntu.
How can I fix it?
Update:
While I was unable to fix the issue in Ubuntu 11.10, it still exists in 12.04 too. I hope someone finds a solution and posts it, as I want to become full time Ubuntu user but only way to connect internet in Ubuntu for now is to use other provider.
And I bet the problem has something to do with providers network band-type. Since both Tata Docomo and BSNL operate on different GSM band, while in Windows, Huawei Mobile partner manages this and I can use any GSM provider to connect with Internet, I guess this is not happening with Ubuntu, and I can only use Tata Docomo and other providers which operate on same band.
A friend is having desktop with on-board nVidia graphics (Its an asus motherboard without discrete GPU). I've made clean install of Ubuntu 11.10 and than installed GNOME shell. And I had following issues.
So I installed "recommended" nVidia drivers from Additional Drivers utility. After installation and reboot, I got
But GNOME shell performance got sloppy and animations were not smooth, and viewing Activities overview looked like shell is freezed.
So I uninstalled the drivers, and reverted back to Nouveau, but I was surprized that shell top panel looks fine even after removal of drivers, and even shell animations are smooth and perfect. But again I have screen alignment improper and portion of desktop was outside screen area at monitor's native resolution.
So I opened Displays and changed the resolution to 1280x720 (which is not the resolution I have for the same system in its Windows 7 installation, 1366x768).
But at this resolution with no nVidia drivers installed. I have all the issues solved acccept a new one. The desktop looks little bit hazy and fonts look like little blurred. I know this usually happens when you switch to the resolution lower than the recommended. But looking at the issues I've faced with proprietary drivers, this is the best working state I've attained for the system.
Note: I also tried installing updated nvidia-current package from ppa:ubuntu-x-swat/x-updates and that also didn't worked and at some point (may be due to my mistake) made system unbootable to Ubuntu, so I got is back to working by purging the ppa and deleting xorg.conf file that the driver utility created.

How to customize live Ubuntu CD?
Ubuntu 11.10 release is just round the corner, and for the first time, I need to remaster the original LiveCD as per my (including most of the colleagues) needs. I'm totally new to remastering Live ISOs and all I know is that I've just "heard" about remastersys which can be used to do this.
Below are the things I'll tweak with original ISO.
I'm not bothered about increased size of ISO due to above bloat that I add.
So, these are my needs, I can do all sorts of customizations but don't know how to include that in ISO, and that's where remastering comes into the picture. So where should I start from?
Note: I'm not bound to use only Remastersys, any other similar app will also do for me as long as it accomplishes above requirements.
After using both Ubuntu 11.04 (for Unity) and Fedora 15 (for GNOME 3), I've reverted back to Ubuntu 10.10 for its better classic gnome experience, and have no plans to upgrade until Oneiric releases (for its Unity and GNOME 3 compatibility altogether), and since 10.10 is older now, the VLC media player in its official repository is way to old, and I'm looking for PPA that provides latest stable VLC in Maverick.
So far, I've tried ppa:ferramroberto/vlc and ppa:n-muench/vlc PPAs, and both say that they have VLC 1.1.10 in the repositories, but after adding the PPA and updating the package information, I do not see updated version of VLC in synaptic, also, running sudo apt-get install vlc mozilla-plugin-vlc shows dependency issues and prevents installing anything. So, what's going wrong? other working PPA suggestions are welcome. Compiling the latest version of VLC manually, or using Lucid-Bleed PPA (which is available for 10.04 only but is known to work in 10.10 as well) would be my last option.
Thanks.
I'm using Artha Dictionary, and all I want to do is hide its icon from the notification area without loosing its functionality (i.e. Ctrl+W to bring up the meaning of selected word and show the same using NotifyOSD.). The only reason why I want to do it is, Artha's icon is not monochrome and hence doesn't integrate well with rest of the icons showing in the panel.
While using Unity, the icon is not shown and I still get proper notifications of word meanings I look up, the icon appears on panel in the classic mode. Removing Notification Area from the panel also removes Artha's functionality. If icon cannot be hidden, I'll prefer to have a monochrome icon for Artha that looks perfect on panel.
After considering all the risks of using GNOME 3 in Ubuntu 11.04, I installed GNOME 3 via PPA. Fortunately, my system is working fine after the installation, but following are three issues which I want to fix.
Also, I wanted to know that how can I make Ubuntu 11.04 completely stock GNOME 3, including all the default applications that it is using.
After using Macbuntu 10.10 theme for a while, I uninstalled it using supplied uninstall.sh file, and now Nautilus icon is missing, and none of the icon theme is showing it. I also found that the launcher of Nautilus i.e. nautilus-browser.desktop is missing in /usr/share/applications/ folder. Now icon looks like that of binary file's icon instead of Nautilus'.
How can I revert this icon back to normal...
