I finally got the time to try to upgrade my home desktop, and I have run into the issue of not being able to read the fonts in the gui installer. They are so small as to be illegible. I have tried passing the boot parameters: gui vga=XXX, but once X comes up, this does not seem to affect anything. I have also tried the text installer, but am unable to select mountpoints when I use it.
Any thoughts about what to try next?
