Xfree, ati and monitor

Hi, i have a problem getting X to work. Asked from some newsgroups and got an advice to post here. Yast2 probed all my hardware correctly: ATI Radeon 7500, Samsung syncmaster 500b, but after typing 'startx' i get the following error: (EE) Screen(s) found, but none have a usable configuration. Fatal server error: no screens found I have made many modifications to XF86Config file, but nothing seems to help. in case you can help me, here are addresses for nessesary files: www.hot.ee/lauriesk/XF86Config www.hot.ee/lauriesk/XFree86.0.log thank you Lauri
