Public bug reported:
When running the 6.10 Edgy Eft or 7.04 Feisty Fawn LiveCD's, the
graphical performance is unusable and very slow. With a Nvidia GeForce
7800GTX, performing things such as mouse-wheel scrolling in Firefox
results in a delayed re-draw of the screen. (a line runs down the screen
drawing the new content) This simple scroll of a few lines takes a total
of a half second or more generally and can be considered unacceptable.
This bug is obviously the fault of the Vesa drivers on the LiveCD and is
carried over when the OS is installed and booted on the HDD with the
default Vesa drivers. When installing the nvidia-glx package and
changing graphics driver in /etc/X11/xorg/xorg.conf, the graphical
performance is fine.
