How do you determine what text-mode resolutions are available with a graphics card? I have been using uvesafb to get higher resolutions, but framebuffer TTY display is very slow, so I'd like to try sticking to text mode.
Edit: Related to this, I did find a utility called svgatextmode, which allows setting the graphics card to arbitrary text-mode resolutions. However, the documentation in the source package explains that it requires drivers for the specific chipset. The program has not been developed for several years, so newer hardware is not supported. The original author advises using the framebuffer instead.
