Occasionally the GPU hangs under normal usage. I don't know which version to specify since there are so many version among the xorg packages, possibly xorg-x11-server-Xorg-1.14.4-11.fc20.x86_64 Here is the relevant section of the journal: Jul 31 21:29:48 worklap gnome-session[1360]: [3373:3373:0731/212948:ERROR:desktop_window_tree_host_x11.cc(1330)] Not implemented reached in void views::DesktopWindowTreeHostX11::MapWindow(ui::WindowShowState) Jul 31 21:29:51 worklap gnome-session[1360]: [3373:3403:0731/212951:ERROR:raw_channel_posix.cc(139)] recvmsg: Connection reset by peer Jul 31 21:29:51 worklap gnome-session[1360]: [3373:3403:0731/212951:ERROR:channel.cc(297)] RawChannel fatal error (type 1) Jul 31 21:30:08 worklap gnome-session[1360]: [3373:3403:0731/213008:ERROR:raw_channel_posix.cc(139)] recvmsg: Connection reset by peer Jul 31 21:30:08 worklap gnome-session[1360]: [3373:3403:0731/213008:ERROR:channel.cc(297)] RawChannel fatal error (type 1) Jul 31 21:30:39 worklap kernel: [drm] stuck on render ring Jul 31 21:30:39 worklap kernel: [drm] stuck on blitter ring Jul 31 21:30:39 worklap kernel: [drm] GPU HANG: ecode 0:0xf4e9fffe, in Xorg [772], reason: Ring hung, action: reset Jul 31 21:30:39 worklap kernel: [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.

Strange, restarting X fixed it. I hadn't tried that before. The last time this happened, even hibernating and resuming didn't fix it.
