Yesterday I saw that Openmandriva Lx 3.03 was released.
The version that I had installed on my laptop was 3.0. I tried 3.1 and 3.2 but they simply would not launch properly and it was until much later that I found a way to circumvent the problem.
I gave this new version a try and I can happily report that:
1. This version is considerably faster.
2. It launches without any problems.
3. Despite the fact that the Openmandriva GRUB 2 replaced my existing Mageia GRUB 2, Mageia now does not have to run the check that makes the system wait for 1:40 before starting.
In addition, Steam works perfectly and Openmandriva picked up my Epson scanner/printer perfectly, too.
