Thanks for your quick reply. Unfortunately, the email got stuck in a spam filter that's why I reply so late.

I wasn't able to get rid of by changing tvtime configuration options, so I thought the best way would be to upgrade the driver to 2.0, which fixed *that* problem. > Could you test the old > hardware with the new > driver, to test whether it's the driver version > change creating a > slowdown? Nope, doesn't seem to be related to the driver change. >30% X CPU usage with 1.7.4. > Also, could you try 2.2 instead of 2.0? If > that doesn't work, > try 2.1. Same thing (I was already looking pretty often if there's a new driver version and jumped on each new version) > It's also possible that the driver's just not as > good on 965 and Q35 as > on 945.

Or does that need to be fixed in the driver? Do you think I should contact the driver developers or file a bug report for the driver? BTW, to rule out any other interference from other pieces of software (e.g., OpenBox) I did start only X and tvtime, still the same problem. > Thanks, > Donnie > -- > [email protected] mailing list > > ____________________________________________________________________________________ Looking for last minute shopping deals?
