I ordered Lx 3.0.1 from OSDisc and gave it a try. I must admit the Live disk was a _very_ slow boot on this I-7 quad-core which has 16Gig of RAM.
What pushed me to look at non-YABU (Yet Another uBUntu) distros is that YABUs are horribly broken right now. They do not correctly identify or work with Doro 626 and a great many other cell phones.
Once the live edition of OpenMandriva Lx 3.0.1 booted, I plugged my phone in and bing! it was recognized as a storage device. I could copy pictures from it. So, I opted to install.
Note: Whoever decided to do monitor spanning for the install shouldn't have made that decision. The dialogs for install pop up in the "center" of the spanned monitors making several inches out of their middle unreadable _and_ it doesn't correctly identify which monitor is left/right so the left side of the dialog is on the far right of the right monitor while the right side of the dialog is on the far left of the left monitor.
Other than that annoyance the install seemed to proceed without a hitch, then I tried to boot and it booted to a black screen.
Like most people running Linux I have an NVIDIA video card so the CUDA core can be used by BOINC. I suspect the install opted to use the Nouveau driver without giving me the option to install the NVIDIA specific driver. This driver doesn't work with the latest KDE, according to the OpenSUSE Tumbleweed install, they pop up a warning about it.
Are there plans to fix the Lx install so a user has the option to install the proprietary driver?
