I have done a clean install of Fedora 8 and done the updates too. I am running a HP nx9420 which has an ATI x1600 video card with the Livna drivers. When the machine is left idle for about 20 minutes or longer the keyboard and mouse stop functioning in X. I can switch to command line (i.e. ctrl-alt F1) and the keyboard works great. The Xorg.0.log shows the following errors. (EE) fglrx(1): [DRI] Locking deadlock. Already locked with context 164288964, trying to lock with context 2. (EE) fglrx(1): [DRI] Unlocking inconsistency: Context 164288964 trying to unlock lock held by context 2 (EE) fglrx(1): [DRI] Locking deadlock. Already locked with context 164288964, trying to lock with context 2. Is anyone else having this issue or know how to solve this? Or am I missing the point here and this is not the cause of the problem. No other errors show in the logs that I can find. Thanks in advance Richard
