Xorg 1.20 HWE for 18.04 breaks dosbox mouse capture


Just a heads-up for DosBox users on 18.04's original graphics stack wanting to upgrade to the HWE version: Xorg 1.20 has a bug which breaks mouse-capture in DosBox, making many games unplayable as a result (see https://www.vogons.org/viewtopic.php?f=31&t=62703).

Upgrading to the HWE kernel is fine, but Xorg should be left alone until a newer release is available in the HWE stack.

Downgrade instructions if you already upgraded:

sudo apt install xserver-xorg-core 
sudo apt install ubuntu-mate-desktop xserver-xorg


I had issues with my Optimus graphic card (nvidia-prime). Basically, I could not get pass the login screen (black screen or freezes with lightdm).

So, same as you. Hwe is a no go for me
