** No longer affects: compiz (Ubuntu) -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1414320 Title: Unity(7) freezes completely after Kernel update (3.18.0.9.9) on intel GMA-965 (Vivid) Status in linux package in Ubuntu: Incomplete Bug description: After I update the kernel to 3.18.0.9.9, Unity freezes few minutes after login on Vivid. This happens for any compiz based session like gnome-flashback(compiz). I tried booting with both the systemd & upstart from boot menu, but the outcome did not change. Ctrl+Alt+F1 or Alt+SysRq does not work after freeze. Just before the freeze syslog prints following error: ---------------------------------------------------------------------- Jan 24 20:50:26 Compaq-610 kernel: [ 114.028185] WARNING: CPU: 1 PID: 0 at /build/buildd/linux-3.18.0/drivers/gpu/drm/i915/intel_display.c:9916 intel_check_page_flip+0xa7/0xb0 [i915]() Jan 24 20:50:26 Compaq-610 kernel: [ 114.028189] Kicking stuck page flip: queued at 16782129, now 16782130 & Compaq-610 kernel: [ 588.815146] gnome-system-lo[2937]: segfault at 14 ip b6c1f4c3 sp bff19e70 error 4 in libglib-2.0.so.0.4303. ----------------------------------------------------------------------- I have attached the complete syslog.txt & xorg.txt (http://paste.ubuntu.com/9852608/) for the session.
