In a computer club, I installed several times LM7.2 RC1 (dated 12 october), and I always encountered the same problem of bad configuration of X : video cards are Matrox Mystique and S3 Virge II DX, which are not detected. In the first case there were also a misconfiguration of X config files (no entry for monitor ?), preventing the correct launch of X, although the choice for install was 'recommanded', leading to an automatic install. At last I managed to make X work, but a beginner would feel completely lost, surely. So I hope that before the release of 7.2 final, the install process will have been tried on a large number of PC. My experience until now shows install problems at least half the time with RC1. I am sorry not to be more precise in bug reporting, but I just wanted to point out this, hoping that mandrakesoft people have enough PC to try out, among them some a bit old.
