- add patch to unblacklist llvmpipe
I've unblacklisted llvmpipe like Fedora has done for a few releases. In
some cases I noticed my normal driver not working (reason unknown), so
in case GNOME is sometimes slow, check if it isn't rendering using
llvmpipe.
On my system, running mga2, unblacklisting llvmpipe (so as to use
regular gnome3, instead of classic/fallback mode) makes all display
in regular gnome3 run extremely slow.
This includes the virtual console, or scrolling in gedit, neither of
which has any need for accelerated display.
It must be that llvmpipe is used for all display, even when
acceleration isn't indicated.
Hmm, that is not good. I'll test for a few days, otherwise I'll revert.
What is reported in System Settings → Details under Graphics? llvmpipe
or something else?
It says
"Carte graphique Gallium 0.4 on llvmpipe (LLVM 0x300)"
Strangely enough, I have now uninstalled llvmpipe and am running gnome3
in fallback/classic mode.
But it said the same thing before uninstalling.
I guess that the message is only set/reset under regular gnome.
I don't think classic mode was slow with llvmpipe installed, but
uninstalled it since llvmpipe was in the libllvm-devel package (version
3.0 on mga2), which is huge (1 G in size).
The equivalent package on fedora is apparently llvm-devel.
(I uninstalled it to leave more space on /.)
BTW, regular gnome3 might well be called "tablet mode". A lot of
extensions have been developped to revert to a display more like
gnome2.
I am not using a tablet and suggest you first try it on a tablet.
My wife has a tablet-like android computer. The default regular gnome3
has the same appearance (and awkwardness to quickly access applications).
Sorry, but don't have access to a tablet powerful enough to run gnome3.
I looked at a number of extensions, and it was surprising how many were
oriented to bringing back a more gnome2-like (and/or less tablet-like)
appearance.
So there are already solutions for most of the appearance problems.
(And if necessary, I'll modify some to regain a convenient environment.)
I'm surprised at the performance problems of llvmpipe. Although my cpu
is 32-bit and 64-bit is recommended, it does have the recommended sse2
function.
See http://www.mesa3d.org/llvmpipe.html
(It has taken me ages to get gnome3 -- classic -- in a usable state.
Next to regain access to svn.)
