Hi,
I have problem on my dell laptop e6410 with internal screen since update to 313.18 and 310.32.
On 313.09 and 310.19 everything was ok.

Screen flickering like on a very low refresh but xrandr show 60 Hz.
Flickering only internal screen. External screen via DisplayPort is ok.

How to reproduce:

→ After update drivers I reboot system (kernel 3.7.4).
Internal screen is ok.
→ When I reboot system and plug in external monitor I enable second screen via xrandr command or nvidia-settings. I used option TwinView and Separate X server too.
→ external screen is ok, internal screen flickering.
disable and enable internal screen
->still that same.
reboot computer to bios or windows
→ screen still flickering. (windows show 60Hz)
disable computer, remove main battery and from mainboard
→ screen still flickering.

Now I’m calling to service … ;) They said me that I should try use old drivers.

so, installing 310.19
→ still flickering
enable external screen, disable internal screen, enable internal screen,
→ everything is ok.

Please explain me what drivers do because I cant understand it.

PS. When I switch on 310.32 between screens Xorg randomly crash.

  1. Post the logs from nvidia-bugreport script.
  2. Downgrade drivers to 304 series, this “fixes” resyncs/flickering on my setup. See here : Repeated monitor flickering/resync with 310.xx driver on Quantal amd64 - Linux - NVIDIA Developer Forums
