este resolveu o problema para mim:
Apparently the only solution at the moment is to downgrade to the previous driver version (304.131).
You can find the 304.131 drivers for Ubuntu this way:
- go to https://launchpad.net/ubuntu/+source/nvidia-graphics-drivers-304/+publishinghistory
- look for the version you need, and click on the version number
- on the next page, look under "Builds" for your Ubuntu release, then click on the
amd64
ori386
link behind the release name- on the next page, look under "Built files" for the .deb file starting with "nvidia-304_304.131". Download that file.
- open a terminal and run
sudo dpkg -i *path-to-downloaded-.deb-file*
to install the downloaded version
mais tarde, basta bloquear a versão do pacote: sudo apt-mark hold nvidia-304
. Quando a nvidia consertar seu driver, não esqueça de desbloquear o pacote: sudo apt-mark unhold nvidia-304
