Everything is noticeably slower :streaming video, moving windows around in the desktop, playing steam games is impossible now and any other kind of game. Searched everywhere for a solution. Will probably revert back to fresh 14.04 install since there seems to be no immediate remedy. keep getting msg: Your system is providing 3D via software rendering rather than hardware rendering. This is a compatibility mode which should display 3D graphics properly but the performance may be very poor. If the problem you're reporting is related to graphics performance, your real question may be why X didn't use hardware acceleration for your system tried several things but could not fix thus far. There didn't appear to be a standard answer for this anywhere. I'm using an older AMD gpu but that shouldn't break everything when it worked well before. I wasn't using proprietary but rather the open source drivers that are supposed to be default.
