What kernel module is being used here versus on the installed system?
The issue may lie in there.

Assuming they are the same, running `modinfo` against the kernel module
(i.e. `modinfo -p sis_agp`) should give a whole list of available
settings. Check to see if there are differences. If there are, set the
installed system to match the live system. It's possible something has
changed since 18.04 was released.

If you can't solve the issue with the above, you can always add a
resolution with `xrandr`, throw it into a script, and make sure it
autostarts. This is covered on [AskUbuntu][1] but basically:

 2. Use the results of the above after "Modeline" to make a new mode:
`xrandr --newmode MODELINE`
 3. Add the mode: `xrandr --addmode DEVICE MODENAME` where you can
figure out DEVICE from running `xrandr | grep connected` and MODENAME is
the quoted portion at the beginning of the modeline
 4. Put 2 and 3 in $HOME/.xprofile and it will be loaded at start
