[ Test Case ] Requires a GeForce 6150SE or similar integrated GPU from nVidia. Problem manifests immediately on login. [ Regression Potential ] The fix involves a specific hardware blacklist. Anticipated regressions include fixed support for the specific hard in future nVidia driver releases and potentially additional unidentified hardware affected by this bug needing to be added to the blacklist. Note that there is a manual workaround to the problem consisting of disabling the X11 Sync feature through CCSM. [ Other Info ] This fix was cherry-picked from the Ubuntu "Vivid Vervet" development release where it has been in regular use for some weeks.
