For me, the situation has significantly improved with the latest Ubuntu 16.04: for "normal" operation, I no longer need "nouveau.config=NvMSI=0" as kernel boot parameter.
I still see that things are not yet perfect: * moving the mouse over the window top bar occasionally shows a black and white pattern in this bar (which disappears, once the mouse has completely left the window). * recently, I had a freeze again after a long time without freezing -- opening a large utf-8 encoded "csv" file with a (wrong) "utf-16" BOM in "libreoffice calc" (leading to lots of nonsense characters). Thus, while the problem is not yet fixed completely, there has been significant improvements (at least for my card). Maybe, the improvements result from a side effect of having used the Nvidia proprietary driver in the meantime. I have seen a report reporting something like "nouveau gives problems - switching to Nvidia; Nvidia gives problems - switching back to nouveau - nouveau problems have disappeared". I have no idea how something like that could be possible - but my case looks similar. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-nouveau in Ubuntu. https://bugs.launchpad.net/bugs/1649566 Title: xserver-xorg-video-nouveau: X freeze To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-nouveau/+bug/1649566/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
