Issue 1 with Precise

Hi O. Sinclair,

I have a somewhat similar laptop: Gateway AMD Turion 64 and ATI Radeon
Xpress 200M 5955 PCIe graphics. No dual vidoe. I initially found it
would not install 12.04 at all due to what I can only describe as an
error in the install routines. Installation stopped and froze when it
could not find a driver for the built in Broadcom wireless card, even
when the wired internet was connected. The solution was to use the
alternate installer and make some changes to the grub scripts when
first time booting, made permanent after the first successful boot.

To return to your question: my laptop is using the generic VGA drivers
and has a speed of less than 60 FPS. Not very impressive. The
"Additional Drivers" utility finds nothing. I tried using the ATI
proprietary drivers but they didn't work. Apparently some ATI cards
are just not supported by the manufacturer, admittedly they are old,
but still worked well in 11.10. The problem may lie with the
people, but I guess you can't expect 6 year old hardware to go on
forever. The ATI fgrlx drivers just won't work for such systems as
yours and mine.
