I had nearly the same problem with a fresh installation of Intrepid and fglrx from the repositories and with the current version available at the amd/ati site. My grafic card is a HD3450.
The driver did work immediately after installation by only restarting gdm but did hang after reboot. I didn't much typing so i didn't see any kernel panics. I only tried to get into another console and to kill X which doesn't work and did a hard reset to reboot the machine into rescue mode. I finally managed to get fglrx back into life without reinstalling by overwriting the file /etc/ati/amdpcsdb with /etc/ati/amdpcsdb.default. I traced back my steps after installing the driver and what i did just before the final reboot and found that aticccle caused the problem which i used to position and resize the visible screen image. I was able to reproduce the failure by using aticccle the named way but changing the TV output (just for testing, a TV is connected) from the default setting to PAL-B didn't cause a problem. May be this information fits to this problem (I'm not quite shure) and is of any use. regards M.Baehr -- fglrx versions newer than 8.543 cause system hang and panic https://bugs.launchpad.net/bugs/314600 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
