--------------- nvidia-graphics-drivers-331 (331.20-0ubuntu0.0.2) precise-proposed; urgency=medium [ Shih-Yuan Lee (FourDollars) ] * debian/nvidia_supported, debian/rules: - Add subsystem ID parsing support for LP: #1255813. [ Alberto Milone ] * debian/dkms_nvidia/patches/register-VT-switch-requirements.patch: - Make sure to call pm_vt_switch_{required,unregister}(), so that the kernel knows that the driver requires a vt switch at suspend/resume time. This resolves a corruption issue on resume from S3 (LP: #1210077). Thanks to NVIDIA for the patch. * debian/dkms_nvidia_uvm/patches/buildfix_kernel_3.12.patch, debian/dkms_nvidia/patches/buildfix_kernel_3.13.patch: - Add support for Linux 3.13 (LP: #1294163). -- Alberto Milone <alberto.mil...@canonical.com> Thu, 20 Mar 2014 11:50:12 +0100 ** Changed in: nvidia-graphics-drivers-331 (Ubuntu Precise) Status: Fix Committed => Fix Released -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to nvidia-graphics-drivers-331-updates in Ubuntu.

Switching to a VT and back to X can potentially solve freeze issues, but corruption may result. [Test Case] Suspend/Resume many times with nvidia graphics and see if the problem happens. [Regression Potential] This is already in Trusty. -- Perform regular suspend, either from system menu or close laptop lid, when system resuming from suspend, it will freeze. Switch to VT and back to X can solve freeze issue, but the screen are gabled and some character rendering are strange, however whole system can perform usual task. found affected graphics: gf108m gf117m gk107glm To manage notifications about this bug go to: https://bugs.launchpad.net/hwe-next/+bug/1210077/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
