Hi. I just noticed that conflict
sudo apt-get -t unstable install xlibmesa-gl1-dri-trunk Reading Package Lists... Done Building Dependency Tree... Done The following packages will be REMOVED: libsdl-mixer1.2-dev libsdl-ttf1.2-dev libsdl1.2-dev libsmpeg-dev xlibmesa-dev xlibmesa-gl xlibmesa-gl-dev xlibmesa-glu-dev The following NEW packages will be installed: xlibmesa-gl1-dri-trunk 0 upgraded, 1 newly installed, 8 to remove and 1 not upgraded. Need to get 0B/1913kB of archives. After unpacking 4301kB disk space will be freed. Do you want to continue? [Y/n] And while we are at it, I now get a blank screen when switching back to console... it even does not go on again when switching back to X... all that helps is putting the machine to sleep and back or reboot. Soeren. PS: You've won the bet. The scrolling speed thing in 2.6. *is* a schedulers issue...
