This occurs because starting from Ubuntu 16.04.2 Ubuntu has enabled HWE Stacks.

Removing hwe packages and installing the correct packages fix the issue

sudo apt remove  xserver-xorg-core-hwe-16.04 #Also remove all the dependencies
sudo apt install ubuntu-desktop xorg xserver-xorg-core #Also install the required dependencies

[Alfro]

Added to docs: teltek/Galicaster-doc@deb3723#diff-49c5a355562dd7a106f2a2311f67b878R17

[rubenrua]

Well done.

[ppettit]

i've struggled with this before and had to enable hwe to get newer hardware working - suggesting to remove it might cause issues?

[Alfro]

@ppettit In which hardware did you have these issues? Maybe we should consider adding a disclaimer with that.

Also, when we release the next bugfix version (2.0.1 Edit: 2.0.2), removing hwe should not be necessary, so I think we could safely remove it from the docs at that point.

Edit: I mean't the version

[dpeite]

Actually this bug it's fixed in the branch 2.0.x and will be in the next release 2.0.2 and not in 2.0.1 like @Alfro said.

[silviabf]

After a fresh installation of galicaster 2.0.2 removing hwe is not necessary, and default profile works correctly. I close this issue.
