Sounds reasonable, if this is the system log.

When I was playing with qemu, I ended up throwing in all the potential drivers, to see which was best for me. That caused me to look at the Xorg logs more than I normally bother. I saw that Xorg identifies something about the hardware, produces an ordered list of drivers, and then tries to load them all, in order, before apparently using the highest-priority driver which both loads and works (for some definition of works - perhaps it only tries to open them, dunno). At the moment, I am on my netbook and Xorg decides to try the following "autoconfigured driver"s : 0. intel 1. intel (fortunately, it only loads it once) 2. modesetting (I enable kms) 3. fbdev 4. vesa Of these, only the intel driver is present, so I get a few lines of output for the missing drivers, and then all the normal output from the intel driver. I will be surprised if vesa and fb are tried before intel, and if they are then I suppose that the messages might be interesting. OTOH, I recall that it took me a few cycles of looking at the log, and then changing what was available, before I really started to understand it, and I wonder if you have perhaps mistaken what it is telling you? By adding a conf entry, you force it to try only the specified driver. I do not think that saving perhaps 20 lines in the Xorg log is worth the trouble ;) > I don't have an ATI video card, but we probably need to revisit the section > in Xorg Drivers labelled 'Glamor Acceleration'.

And for nouveau, I believe someone said glamor was for the latest hardware. So, what sort of change did you have in mind ? ĸen -- Nanny Ogg usually went to bed early. After all, she was an old lady.
