Public bug reported:
Firstly, my apology for a relatively inexact bug report but i'll try to
mention the important factors.
After purchasing another 4gb memory for my ubuntu desktop, the BIOS
identified the memory correctly. Ubuntu showed only 4gb memory. Since
the PC had Ubuntu installed pre-memory-upgrade, it was using the generic
kernel which was by default correct for a 4gb PC.
To get my new memory recognized in ubuntu, i had to google a fix to
this, which was a nicely documented ubuntu howto and the fix was a one-
line command to get the PAE version of the kernel activated. A reboot
later, the memory issue was fixed.
I would like Ubuntu, somewhere near the end of the startup process, to
automatically check for the scenario "if the PC is using the generic
kernel, but BIOS memory is over 4gb, to pop-up a suggestion to activate
PAE"
In line with making "things just work" this should be relatively simple
to implement but would assure end users are not left alone to try to fix
similar issues. At least Ubuntu 12.04 LTS did not pick up on this
automatically.
Does anyone second this?
Is the proposed modification sensible and doable?
