Re: Beta 1: Tweak for old Intel graphics

 

The UXA tweak works in my Toshiba too,

http://www.toshiba.se/laptops/satellite-pro/c850/satellite-pro-c850-19w/

with Intel i5 and built-in graphics

Intel 3rd Gen Core processor Graphics Controller (rev 09) (prog-if
00[VGA controller])

Would it be safe to have it as default, or could the UXA tweak do any
harm for some version of Intel graphics? Maybe the entry in

/etc/X11/xorg.conf

could be more specific, so that it will be used only for old Intel graphics?

Best regards
Nio
