LXQt 0.9

LXQt 0.9, the lightweight desktop environment (merge between LXDE and Razor-qt), was released this Sunday. The new release drops Qt4 and now requires Qt5.

Besides enforcing Qt5, LXQt 0.9 comes a new LXQt Frost theme, lots of UI and internal polishing and several new features. See the official release note.

Install / Upgrade LXQt 0.9 in Ubuntu:

For (L)Ubuntu 14.04, (L)Ubuntu 14.10, and upcoming (L)Ubuntu 15.04 users, LXQt 0.9 has been made into PPA. Just follow below steps to install or upgrade it.

1. Open terminal from the Dash or by pressing Ctrl+Alt+T on keyboard. When it opens, run command to add lubuntu daily build PPA:

sudo add-apt-repository -y ppa:lubuntu-dev/lubuntu-daily

2. After that, update system package cache and install LXQt by running below two commands one by one:

sudo apt-get update

sudo apt-get install lxqt-metapackage lxqt-panel openbox

Once the installation finished, log out and log in back with “LXQt Desktop” session and enjoy!
