I haven't been able to switch to the VESA driver. When I make an /etc/X11/xorg.conf file to do that, I get this error in my /var/log/Xorg.*.log:
[ 21.764] (EE) VESA: Kernel modesetting driver in use, refusing to load
However, I noticed the emacs problem doesn't seem to occur as the root user. So I deleted several .* files and directories (settings files and dirs) in my home directory. After I logged out and logged back in, I no longer have the emacs display problem. Unfortunately, I didn't delete them one at a time. I have a back up of them. I'll let you know if I find the one that caused a problem.
