Hello, I have been using Qubes OS on a Purism Librem Laptop for the last year and a half and I think it is great - I could never go back to using a regular os afterwards.
But I think it still has some issues with stability and maybe even security in extreme cases.
One problem is that mouse and keyboard gets “stuck” sometimes. It happens like this:
-the ps/2 laptop keyboard stops responding at all, no key press is being registered by the os.
-the mouse is being “pulled” to the lower right (sometimes upper right) corner of the screen and no matter how hard I try to control it with the (ps/2) trackpad it still gets pulled back to the corner of the screen.
-os is not frozen, I can still click with the mouse but I can only move the pointer with great difficulty before it gets pulled back.
-I tryed restarting sys-usb vm or keep it powered down at all times but the problem still persists.
-only fix is to power down the laptop and restart the os.
1)Could this be an attack? Could a restricted vm move the mouse pointer forcefully and also lock the keyboard or is it a hardware issue caused by the librem laptop?
2)Is there any way I could reset the ps/2 devices somehow to regain controll over the imput?
3)Is there any way to debug the problem? I can’t seem to find anything in the logs.
Is anyone having similar issues or knows how to debug them?
System: Purism Librem 13 Laptop v3 with disabled the Intel Management engine and coreboot BIOS.
OS: Qubes OS 4.1 (R4.1) Xen 4.14.4
