What kernel module is being used here versus on the installed system?<br>
The issue may lie in there.<br>
<br>
Assuming they are the same, running `modinfo` against the kernel module<br>
(i.e. `modinfo -p sis_agp`) should give a whole list of available<br>
settings. Check to see if there are differences. If there are, set the<br>
installed system to match the live system. It's possible something has<br>
changed since 18.04 was released.<br></blockquote><div><br></div><div>OK, I'm not familiar with this sort of thing. How do I change the installed system to match the live system?
