I can also confirm what was written above.

[Bug 1634451] Re: Screen flickers when booting ubuntu 16.10 on USB stick
It was not quite correct what I said about flickering stopping only when
mouse moves. It also stops when something is output continuously to the
terminal window. For example, running the following command in gnome-
terminal window:
perl -MTime::HiRes -E '$i=0;while (1) { $i++; Time::HiRes::sleep( 0.2 );
say "Hello $i" }'
causes the flickering to stop. However, if I increase the sleep delay
between writes to the terminal from 0.2 to 0.3 seconds, flickering
starts again. So the output must be continuous for the flickering to
stop.

I have the same problem. I installed a fresh Ubuntu 16.10 on my Lenovo Edge540 laptop. Screen starts flickering during installation from USB and only stops when the mouse is moving. Very annoying.

I just tried the latest daily image. The flickering is still there. Additional information: 1. I tried connecting a secondary monitor via HDMI. The 2nd monitor does not flicker. 2. When the mouse pointer is moving, the primary monitor does not flicker. 3. When the web browser is loading, the primary monitor does not flicker. However, while the mouse is idle, the mouse pointer jitters. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1634451 Title: Screen flickers when booting ubuntu 16.10 on USB stick To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1634451/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
