Severe screen flashing on 7.4M0

mekul · 09-06-2013, 06:14 AM

Hi,

Since installing 7.4M0, my second screen has been flashing black, as well as going blurry all the time. I have a laptop + 2nd monitor plugged into a Toshiba dynadock U3.0. I did a clean install for 7.4 driver.

This setup was not flashing on 7.3, but I was having consistent network dropouts on 7.3 so that's why I updated. As far as I can tell the network is better, but screen flashing is very bad.

Any thoughts?

Log attached.

No issues when I ran compatibility check.

Also the network issue is still happening - consistent dropouts throughout the day.

If I use the wifi instead of the dock's connection, there are no dropouts at all.

Hi,

Thanks for the info - I've raised this internally for further investigation.

Are the ethernet dropouts random or do they occur after a specific event?

Thanks,
James

The dropouts seem random, happens probably 10 times day that I notice, could happen more often.

Another odd thing I noticed is that my second monitor does not 'sleep' any more when I remove my laptop overnight. It used to go to sleep after the laptop was disconnected.
