Xorg.0.log

Video card: ATI Technologies Inc Radeon RV100 QY [Radeon 7000/VE]
Monitor: Samsung SyncMaster 750s

Monitor in stand-by 

video: http://it.youtube.com/watch?v=hr7p6WXLCQk

xorg.conf in gutsy don't work setting right monitor frequency and/or modelines...

Feisty (Ubuntu 7.04) works very good (with ati/radeon driver 3d working...)

Does the monitor work ok on the other port?  Could you try the ati driver in git master?
Comment 2 Guido Iodice 2008-06-20 03:46:35 UTC 
@alex: there isn't other port... only 1 vga

Do you mean there is only one physical port total or that there is only one VGA port?  According to your log your card has 3 ports: VGA, DVI, and S-video.
Comment 4 Guido Iodice 2008-06-20 08:10:32 UTC 
Yes, but monitor has only VGA port. So I can connect it to card only by VGA port.
Comment 5 Alex Deucher 2008-06-28 17:32:26 UTC 
Any chance you could try the recently release 6.9.0 version of the driver?
