Re: [Libreboot] VGA Output Slow With GNOME

[Joshua Bowren]

There seems to be a old bug report for this on gnome's bug tracking 
system https://bugzilla.gnome.org/show_bug.cgi?id=650994, however this 
report is from 2011 and still open. It seems to effect older intel GPUs. 
Reading through the comments, it might be that old intel GPUs do not 
support high resolution texture sizes, which causes gnome to fall back 
to software rendering while plugged in. Gnome's software acceleration 
was supposed to improve by the time fallback mode was removed, but it 
still seems too slow.

Unfortunately the last comment seems to be from January of 2013, they 
might have temporarily given up on this issue. Perhaps it is better to 
just use a different desktop environment for using external displays. 
Weird since Denis said KDE seems to work fine. I would think KDE would 
be even more resource demanding than gnome.
