I'm not running Compiz, but I have been having similarly sluggish behaviour from most tasks which require screen refreshes - moving windows, scrolling documents or text, etc. OpenGL is using hardware rendering. I posted a message about it yesterday with the subject "F10 display problems". I have a few other issues with X that I reported there, I'd be interested in knowing if you see any of them. They are: - switching to a console (such as Ctrl-Alt-F2) and back makes OpenGL switch from hardware rendering to software rendering (this is the most reproducible issue - it always happens - the next two I cannot reproduce on demand, but seem to happen at random) - sometimes, when switching to a console, instead of the console I see a what looks like a corrupted copy of my desktop (though I cannot interact with it at all). Switching back to the desktop is fine, but the consoles all seem to stay that way until I reboot. - occasionally, X dies completely - my screen goes black, and several seconds latter the gdm login screen comes up. > (II) intel(0): Attempting memory allocation with tiled buffers. > (EE) intel(0): Failed to set tiling on front buffer: rejected by kernel > (EE) intel(0): Failed to set tiling on back buffer: rejected by kernel > (EE) intel(0): Failed to set tiling on depth buffer: rejected by kernel > (II) intel(0): Tiled allocation successful. > > (II) intel(0): EDID for output TMDS-1 > (II) intel(0): EDID for output TV > (EE) intel(0): underrun on pipe B! > (II) intel(0): EDID for output VGA > (II) intel(0): EDID for output LVDS > I don't get any of those. The only errors I have are: (EE) Unable to locate/open config file ... (EE) open /dev/fb0: No such file or directory and yep, I do seem to be missing a xorg.conf, odd that I didn't notice that before. Who is responsible for generating xorg.conf on F10? I used to know for early Fedora releases... The log file does report the default configuration that it is using, it picks the "ati" driver. F9 used "radeon".
