Weird pixelated white border. Ubuntu Xenial (16.04) [duplicate]
Solution 1:
The culprit is the new version of the NVidia driver. Reverting to 375 doesn't work because IMHO it has also been updated (minor version) and/or its dependencies are a mix of several versions. Anyway:
- Remove the PPA. On my computer I deleted the file
/etc/apt/sources.list.d/graphics-drivers-ubuntu-ppa-xenial.listpointing to the repositorydeb http://ppa.launchpad.net/graphics-drivers/ppa/ubuntu xenial main - Remove all the installed NVidia packages, i.e.
nvidia-*. On my computer I deleted several packages withapt remove nvidia-361 nvidia-375 nvidia-378 - Update the packages list with
apt update - Install the last official version (i.e. 367) with
apt install nvidia-367
As a side note, I'm always amazed how updates regularly break Ubuntu...
Solution 2:
Its' not a solution per se, but it helps to get the white borders removed.
We just need to restart the Unity, by using the following command -
unity --replace,
which will restart the Desktop Manager, but will keep are current Session intact.
So no logout/login needed, just call the above command whenever these NVIDIA drivers create your screen unusable.
EDIT-
Have tried this solution only on Ubuntu, so I guess most of the Debian Distro's will work here, but not sure about any other Linux Distro.
UPDATE
Above Solution was a temporary one... As it is true that latest drivers of NVIDIA breaks Ubuntu... I guess u should try the solution in the following link - Strange artifacts along window borders
As nvidia-367 updates itself automatically to nvidia-375, we need to get a stable nvidia-370, which doesn't update itself. This solved my issue, but I am still not convinced, as I still get screen tearing when watching a high-res video...
Solution 3:
Updating the Nvidia driver to 384.69 solved the issue for me.
In "Software and Updates" open "Additional drivers" tab an there should be "nvidia-384" option available. Select->Apply Changes->Restart
