I don't know what exactly cause slowdown, it appears to be a regression.I am seeing a slow gnome-shell in rawhide (up to date, as of today) as well on this ATI card: RV370 5B64 [FireGL V3100 (PCIE)] (rev 80) gnome-shell and X are taking each, 100% or one CPU core. It turned out glxinfo says at some line: OpenGL renderer string: Gallium 0.4 on llvmpipe (LLVM 0x301) which means I am running the (slow) software render. The reason is that the r300 driver couldn't be loaded b/c my user doesn't have the rights to open /dev/dri/card0: $ getfacl /dev/dri/card0 getfacl : suppression du premier « / » des noms de chemins absolus # file: dev/dri/card0 # owner: root # group: video user::rw- group::rw- mask::rw- other::--- I should have my user in there, as ajax says in https://bugzilla.redhat.com/show_bug.cgi?id=745316. I am running this rawhide box using init 3 (/lib/systemd/system/multi-user.target) as the default init level, and I am running the desktop by doing: xinit /dev/gnome-session So somewhere something is failing to make my user be properly acl'd onto the /dev/dri/card0 device, and I have no idea what I should do to have it fixed. Anyone has got an idea? Note that running the fallback mode by doing xinit /dev/gnome-session --session=gnome-fallback works fine. For now I have just added my user into the video group to have the r300 driver be loaded properly.
