Hello guys! I'm a Linux newbie and I'm having a little problem.
I do a clean install of Mandrake 10.1 Official. On the setup, I choose the Radeon(fglrx) driver, configure the two "heads" of my graphics card (a Sapphire ATi Radeon 9000 Atlantis Pro 128 Mb), select monitor, etc.. Then computer reboots, enters Mandrake without any problem. If I restart the computer, it will restart without any problem too. The problem comes when I completely shutdown my entire system. I do the shutdown, and when I start my machine again and start Linux, after the loading screen, the computer freezes just before the login screen appears. The strange in all this is that, if I hit the reset button, go to Windows XP, reboot and go to Linux, it is all ok again. I'm temporarily using the Radeon(fglrx) driver with Xinerama extension and it doesn't have this problem, but I would like to use 3D Hardware Acceleration, so I could play Unreal Tournament 2003 and emulate some of mine Windows games, to see if they run better. Please help me!

Thank you for your atention;

have you enabled POSIX Shared Memory on your system?
perform the following as root:

1. Add the following line to /etc/fstab (if it isn't there already): tmpfs /dev/shm tmpfs defaults 0 0
2. Mount shared memory as follows: mount /dev/shm
3. Issue the following command to check that it mounted properly: mount | grep "shm"

If the mount was successful, then the following output (or similar) should appear:
tmpfs on /dev/shm type tmpfs (rw)
