I got an external monitor to work, but still no luck with just the laptop. I retried the Intel Linux graphics driver installer but changed my system info to look like 14.10 to get any kind of driver (fails if using 15.04). It says libopenvg1-mesa is missing from whatever repo it is trying to download from. So, I found it somewhere else and installed it. Didn't help the installer at all. So, I guess my laptop is a desktop now. Kinda sucks since the older MacBooks get hot enough that I've replaced my battery twice due to swelling. But since primarily using Ubuntu, I've had no battery problems. It just turns itself off if too hot. Fun fact.

NAME

       bestups - Driver for Best Power / SOLA (Phoenixtec protocol) UPS equipment

NOTE

       This  man  page	only  documents  the hardware-specific features of the bestups driver.	For information about the core driver, see nutups-
       drv(8).

SUPPORTED HARDWARE

       bestups was designed to monitor Best Power UPS hardware like the Fortress, Fortress Telecom, and Patriot Pro.  It also recognizes and  sup-
       ports SOLA units such as the 520 and 620.

       Other  UPS hardware using the Phoenixtec protocol should also work, but they will generate a warning since their battery information is not
       known.

       This driver does not support some older Best/SOLA units.  Try the bestfort driver if this one does not detect your UPS.

EXTRA ARGUMENTS

       This driver does not support any extra settings in the ups.conf(5).

BUGS

       The battery percentage is derived from the voltage data that the UPS returns, since the UPS doesn't return that value  directly.   On  some
       hardware,  the charge will remain at 100% for a long time and then drops quickly shortly before the battery runs out.  You can confirm from
       the BATTVOLT readings that this is a problem with the UPS and not this driver.

       Similarly, the float from the charger in some models forces the battery charge percentage back up to 100% immedately  after  the  UPS  goes
       back on-line, so you can't tell when it is really recharged.

       Finally,  some  models  give one value for the battery's nominal voltage and yet actually have a nominal voltage slightly below that.  This
       leads to things such as the perpetual 98.7% charge on the author's Fortress 750, even when it's been charging for weeks.
