Hi Christopher, I spent 2 or 3 16-hour days trying to bisect this bug every-which way. I eventually punted, and just bought a newer graphics card -- they're cheap -- a few hundred $$ and that "fixed" the problem.
Summary: the old card works great under ubuntu 12.04 but has issues, as described above, under 14.04 My debug efforts centered on doing a git-bisect of the kernel git sources. Somewhere early in the kernel-3.0 series, the card works fine. Somwhere a bit before linux 3.13, the card either would not run X11 at all (and hose the tty as well) or x11 would come up for a few hours, and then hit the TTM messages. I reported the git bisects (two of them, one for each bug) to the nouveau folks, but did not get impression that they were able to do anything about it. -- 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/1406401 Title: Nouveau TTM Failed to find memory space for buffer To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1406401/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : [email protected] Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
