Within a few minutes of trying out the emulator it seems to freeze my desktop (running Ubuntu 20.04). After this happened I noticed however that desktop apps such as browsers playing clips were still working. Even my caps lock key made a sound (although it did not change the keyboard light indicator).
At first, I thought this was likely due to hardware and hax and the like. I wasn't able to change this in the bios but eventually I learned to just try a couple of devices that allowed software emulator, such as the Nexus 6.
However even with this, the 'freezes' continued. As I noirmally use a KVM devioce to share keyboard and mouse and screen between my pcs, I then tried plugging in a different keyboard directly into the specific desktop I am using (i.e. not thru the KVM switch) and it worked! For a while... but then it also froze. Then I continued on, using a small mobile keyboard device that includes a small track pad and so far this has kept working.
My suspicion so far is that, given I am using an Android Emulator, somehow the emulator is 'stealing focus' or grabbing control or something like like for my keyboard / mouse.
The same happened with my mouse, initially stopped working through the KVM switch setup that I have. Then a direct USB plugin wireless mouse worked even though the KVM connected one had stopped working. Then this second mouse stopped working and I was down the the small keyboard approach which has a little trackpad that kept working.
Question: How to stop the emulator taking my keyboard and mouse focus effectively freezing my existing external devices.
Note: The issue is about my desktop keyboard, NOT the emulator keyboard, i.e. when it freezes my whole desktop in not accessible through its keyboard and mouse.
The best solution is to change your driver to the proprietary Nvidia driver. You could do it in
then reboot and the problem should be solved.
Note:
In some cases changing the nouveau driver to NVidia might freeze Ubuntu at boot (before login screen) for some users.
