I'm newbie in Ubuntu desktop - I used Gentoo before. But when I installed nvidia drivers, this file has been created:
me@ubuntu-vbi:~$ cat /etc/modprobe.d/options #Fix for nvidia flickering - (K)ubuntu 9.04 and 9.10 options nvidia NVreg_RegistryDwords='PerfLevelSrc=0x2222' options nvidia NVreg_Mobile=1 So I thing, that the same problem was in prior versions and /etc/modprobe.d/options solves problem. But I can't confirm if it really works in older version of Ubuntu. In Gentoo this options works. If you delete options in Gentoo, symptoms of my problem are the same. Screen is flickering and freezing. With options in Gentoo no freezing, no flickering. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1251042 Title: Ubuntu gnome freeze after start - nvidia drivers Status in “linux” package in Ubuntu: Confirmed Bug description: Nouveau is unstable - sometimes is freezing, i tried to use current proprietary drivers.
