Dear Stefan, Yes "Wheezy" under GNOME-2, and "Jessie" under GNOME-3
I see, it has to do with graphics after all. X.Org's XAA and EXA are 2D accelerators, right? My PC mainboard manual states it has got on-chip AGP 2D/3D. "Wheezy" performs well with XAA, that is not maintained upstream any longer. Many thanks so far. -- Tomas Kral <thomas.k...@email.cz> On Mon, 2016-05-16 at 10:12 -0400, Stefan Monnier wrote: > > "Jessie" is not generally very responsive compared to "Wheezy", display > > update and mouse tracking is very very slow. > > Could it be that your wheezy install did not use Gnome-3 and that you're > now using the standard Gnome-3 desktop (which presumes existence of 3D > GPU acceleration) on a system whose graphics card either has no 3D > abilities (or whose 3D abilities are not supported by the X.org driver)? > > If so, try some other desktop: Gnome classic (not sure if it relies on > 3D hardware as well, tho), Mate (a derivative of Gnome-2), xfce, ... > > > Stefan >
