Firstly you will have to fix the problem of the system booting into a
'lo-res' mode. You should be using the nvidia driver. If there is an
/etc/X11/xorg.conf file, you can check that the proper driver is set to
load. If there is no xorg.conf, read the /var/log/Xorg.0.log file, to
see that was used and loaded.
You may need to add 'rdblacklist=nouveau' to the kernel line in
grub.conf to get that driver out of the way. I have no idea how nvidia
drivers are installed under ubuntu, but I assume the proper driver files
exist in the repos. (ie. you can use apt-get install nvidia or somesuch).
Read /usr/share/doc/NVIDIA-GLX/README.txt at Appendix E, concerning Dots
You may have to force a proper DPI setting. This is an overall setting,
not directly related to the point size.
If your desktop is messed up, then it this that needs to be fixed. (and
only then fiddle with the font size settings in the desktop settings
area...been there, it was not pretty...)
When all that is correct (at it is not clear that things *outside* of
myth are correct), then you can look at myth itself.
I had the same problem, and it turned out to be the DPI setting. It was
REALLY hard to install when you couldn't read the prompts!!
