Ulteo Open Virtual Desktop
Ulteo Application System (Ulteo AS) was a Debian/Ubuntu-based Linux distribution created by Gaël Duval, the original founder of Mandrake Linux (now Mandriva Linux) and co-founder of MandrakeSoft (now Mandriva). It was a hybrid, network-oriented and mostly automatic computing system that ships with hundreds of applications and innovative features. The basic version of the Ulteo AS provides a choice of applications for daily use, such as Firefox, Thunderbird, OpenOffice.org, etc., but can be easily extended with a set of applications from the Ulteo panel. It also provides document and panel content synchronisation capabilities between a local installation of Ulteo AS and Ulteo Open Virtual Desktop.

Q4OS is a lightweight Linux distribution based on Debian. The distribution's latest release is Q4OS 3.8 which is available in two desktop editions: KDE Plasma and Trinity. "Q4OS Centaurus is based on Debian Buster 10 and Plasma 5.14, optionally Trinity 14.0.6, desktop environment, and it's available for 64-bit and 32-bit/i686 PAE computers, as well as for older i386 systems without PAE extension. We are working hard to bring it for ARM devices too. One of the Q4OS specific goals is the ability to have Plasma and Trinity desktop alongside each other installed. Users can switch back and forth between more advanced Plasma or efficient Trinity desktop. Both desktops can independently coexist side by side and don't interfere with each other. Plasma is being the logical primary choice for most of users, so it's considered to be the default option, which is also obvious from the Q4OS downloads site. Q4OS 3.8 will receive five years of security updates. Further details can be found in the project's release announcement.

Distribution Release: Q4OS 4.6 |
|
Q4OS is a lightweight, Debian-based distribution featuring the KDE Plasma and Trinity desktops. The project's latest version is Q4OS 4.6 which is based on Debian 11 "Bullseye". One of the project's aims is to allow both desktops to be installed alongside each other, a rare feature given the shared history of the two desktops. "Q4OS Gemini is based on Debian Bullseye 11 and Plasma 5.20, optionally Trinity 14.0.10 desktop environment, and it's available for 64bit/x64 and 32bit/i686pae computers, as well as for older i386 systems without PAE extension. We are working hard to bring it for ARM devices as well. Desktop profiler, an exclusive Q4OS tool, has custom profiles support now, so a user can export the current desktop status snapshot, modify it and even create customized profiles on his own. Any profile is importable, so a user can import and apply it later on another hardware, getting a unique possibility of easy installation and configuration of the pre-defined set of applications and packages at once. In other words, a user easily gets a fresh operating system installation configured and ready to work with a minimal post installation effort. In addition, each desktop environment may keep its own applications profiles." Additional information can be found in the project's release announcement.
