Ubuntu 16.04 flashing

dr_torch · 05-24-2016, 04:45 PM

Hello everyone.

I am using the new driver on 16.04. Install goes fine but after I reboot I get the login screen and after I login it seems to detect the second monitor but then I get some sort of seizure inducing flashing and then a black screen with only the cursor.

You have to do CTRL+ALT+F1 to get a console to reboot.

I tried plugging in the dock after boot up, but the same thing happens. Everything works fine in Windows.

It is an Aluratek USB 3.0 dock and I have it connected to a DVI monitor. The laptop is connected to the dock and to another external monitor via HDMI.

The strange thing is, it was working last week, and I do not recall changing anything.

Can someone point me in the direction of a log file that may help me out?

Thanks.

Ok, so somewhat of an update:

I resolved the issue by removing unity and installing ubuntu-gnome-desktop.

Everything works ok, but I have mouse artifacts left on both of the screens. Any suggestions to fix this would be appreciated.

Thanks!
