This affects me too. I'm using 10.10, 460 GTX. However I found that nouveau kernel module is still loaded on boot even if nvidia proprietary driver is installed and activated. When I blacklisted nouveau the issue looks to be fixed.
Disabling nouveau is described here ftp://download.nvidia.com/XFree86/Linux-x86_64/260.19.12/README/commonproblems.html It is needed to create /etc/modprobe.d/disable-nouveau.conf file with the following two lines added: blacklist nouveau options nouveau modeset=0 After doing this I didn't meet this issue for 3 days. -- X with nvidia takes 3 minutes to load https://bugs.launchpad.net/bugs/657106 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
