Responses to your previous questions: 1) It may take a bit of time before I can make the tests with the current Ubuntu version. And, I fear that such tests might not be reliable: after the temporary use of the NVidia driver I could use the "nouveau" driver for some time even without the special boot parameter "nouveau.config=NvMSI=0" - only after some months, new freezes occurred. I have the feeling that the problem (now) arises non-deterministically -- likely dependent on environment factors such as temperature and/or humidity. While freezes are now rather rare for me, I often observe that the top bars of my windows (usually black) are drawn in an irregular black/white pattern (similar to the freeze pattern) when I move the mouse pointer over the bar. I have the feeling that this is related to the freeze problem.
2) I had no crashes in Ubuntu 12.04 - without any kernel boot parameters. But, I am not sure that under 12.04, I was already using the "nouveau" driver. Earlier Ubuntu versions have been using another standard driver for NVidia cards (likely "nv") and I can no longer remember which Ubuntu version has switched to "nouveau". I myself did not actively switch to "nouveau". 3) I could use the NVidia driver for some time under Ubuntu 16.04. But, its use is unstable in the sense that an Ubuntu update can render it dysfunctional (apparently, a post installation step has problems to properly integrate the NVidia driver) and it is very nasty to fix things up afterwards (I must use a different driver and then reinstall the NVidia driver via "system administration"). I therefore switched back to "nouveau". -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1649566 Title: [GeForce 7025 / nForce 630a] System freeze To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+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
