I don't have KDE installed right now to test. As I remember with Kubuntu 15.04, KDE was creating two files to override GTK theme settings. GTK2: ~/.gtkrc-2.0 GTK3: ~/.config/gtk-3.0/settings.ini As they are two separate file you can change them differently. But you may need to change them to read-only so KDE config tool will not able to change them. ...

You can edit the configuration file directly, but you may have to install lightdm-gtk-greeter (if not already installed). Go to the terminal and type: sudo apt-get install lightdm-gtk-greeter Then edit the configuration file: sudo nano /etc/lightdm/lightdm-gtk-greeter.conf or if you prefer to use a GUI text editor, sudo -i kate /etc/lightdm/lightdm-...

Those packages are available in the repositories, though in newer versions sudo apt install libgnutls-dev libgnutls-dev:i386 Will install the packages you need.

Error E: The value 'wily' is invalid for APT::Default-Release as such a release is not available in the sources occured during repositories reconfiguration. It was caused by content of /etc/apt/apt.conf where wily was set instead of xenial. I changed this file's content to APT::Default-Release "xenial"; and next upgrade attempt finished successfully.

Inspired by http://askubuntu.com/a/504402/458355 I created /etc/lightdm/lightdm.conf with the following content: [SeatDefaults] user-session=plasma-kde Now login works. For the record: The file ~/.dmrc containes the line Session=kde-plasma-kf5 However, changing this line to Session=plasma was ignored by lightdm.

Try to rename the file and then reopen it again. For me it happened when i tried to highlight a line, the whole file suddenly turned blank white. I renamed the file and reopened it and it displayed the pages normally again, but unfortunately without the highlighting... i don't think that Okular can handle such large files, mine was 90MBs

Yes, KNode has been removed as it was using old code and no one has volunteered to keep it up to date. Thunderbird has support for usenet. Source: http://www.aegiap.eu/kdeblog/2015/08/kdepim-5-0/

This was due to bug-report #1576455 "SRU KDE-language-packages-mismatch". Even though it took a longer while, the subject should have been settled by now. The packages were stuck quite a while in the "proposed-queue". It's not the dutch language alone, but any language was affected. So the packages should arrive now via normal updates. Even during ...

There is a much simpler way to achieve the upgrade: 1st goto -> Software Sources -> Updates There is a field that allows the system to check for new versions: LTS only / any / never. Select "any" LTS will only be available with 16.04.1 Just remember to set it back to LTs before Oct.2016 if it's not in your nature to go in sync with every new release of (K)...

Try to remove .kde;.gconf;.config hidden in your home folder. Press Ctrl-H to show them and then relogin. Remember every time you log into KDE Plasma, it will automatically restore these folders, which are required for KDE to work, so before you logout of KDE, delete them again if you want to use unity after that.

A better way would be to copy the contents of /usr/share/kde4/apps/solid/actions/ to /usr/share/solid/action instead then issuing the command : kbuildsycoca5 --noincremental Once this is done, go to system settings and look into the device actions. Doing it this way makes a reboot or logout/login unnecessary.

First of all, group IDs (GID) below 1000 are used by the system and other no-login groups and usually not as primary group for normal user accounts. You should give your user a GID above 1000, ideally the same number as its user ID (UID). Second, file system ownership is bound to user/group IDs, not names. Therefore changing your account's UID and GID will ...

Just keep your Lubuntu installation and add the KDE packages. No need for a second installation or anything else. Be aware - all those thousand Ubuntu-distributions basically use just different default packages - thats all. Therefor if you want another desktop environment, install the related packages and that's it. The following command should be enough ...

I tried the same command with this other path: /lib/x86_64-linux-gnu/libresolv.so.2 And now it works. Hope it will be useful for someone! (I still don't know why I have this lib repeated so much, I suppose they are different compilations, for 32, 64 bits, aren't they?)

Consider changing the partition to ext4; if your system is all Ubuntu there is no reason to put up with the overhead associated with using an ntfs file system.
