Tom Winterhalder, as the latest version of the driver in the repository
is also the latest one available from nvidia.com, the bug you are
reporting is an upstream one. Could you please report this to them via
https://help.ubuntu.com/community/BinaryDriverHowto/Nvidia#Reporting_an_upstream_bug
?
As well, could you please comment to if using nouveau offers a
WORAKROUND?
** Summary changed:
- Flickering with Ubuntu 14.04 and nvidia card reappeared
+ 10de:0cbc Flickering with Ubuntu 14.04
** Description changed:
- As requested in Bug #1310633 I'm opening a new bug.
-
With a previous version of Ubuntu I already had this flickering. With
additional options for the kernel module I was able to fix the
flickering.
options nvidia NVreg_RegistryDwords="PerfLevelSrc=0x2222" NVreg_Mobile=3
NVreg_ModifyDeviceFiles=0
With version 14.04 and the nvidia-331 (331.38-0ubuntu7) driver the
flickering reappeared although the line is still present in
options.conf.
Using modprobe --resolve-alias nvidia I found the correct driver module
name which in my case is nvidia_331. Changing the module name in
options.conf to nvidia_331 X doesn't start anymore. Removing the
NVreg_ModifyDeviceFiles option X is starting again, but does not solve
the issue.
