[Bug 1033899] New: No V-SYNC (Desktop Tearing) with Intel Sandy Bridge using default fbdev. (GNOME Wayland & Xorg)
http://bugzilla.opensuse.org/show_bug.cgi?id=1033899 Bug ID: 1033899 Summary: No V-SYNC (Desktop Tearing) with Intel Sandy Bridge using default fbdev. (GNOME Wayland & Xorg) Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: x86-64 OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: X11 3rd Party Driver Assignee: xorg-maintainer-bugs@forge.provo.novell.com Reporter: hdavolt@gmail.com QA Contact: sndirsch@suse.com Found By: --- Blocker: --- GNOME 3.24 Tearing (no VSYNC) is noticeable on Sandy Bridge (HD 3000), especially when moving/resizing windows. This happens in both Wayland and X Sessions. Installing XF86-video-intel (and dependencies) resolves the problem. Since intel driver is deprecated(?), using the fbdev driver should produced desirable results. -- You are receiving this mail because: You are on the CC list for the bug.

Hmm. Fallback to software rendering. :-(
With modesetting, that's normal when we don't have GLAMOR, since the modesetting DDX uses GLAMOR not only for 2D, but also as glue code for 3D support. -- You are receiving this mail because: You are on the CC list for the bug.

It's strange to see GLAMOR failing to init, maybe something is wrong with either of the kernel/Mesa/Xorg... Also, what about "sudo lspci -nn" ? -- You are receiving this mail because: You are on the CC list for the bug.
