+
I run Ubuntu 19.04 on Dell inspiron 7000 2-in-1.
After a fresh install the touchpad doesn't work, the touchscreen doesn't
work, when the laptop doesn't recover after a suspend to RAM, it boots
only with noapic option. The laptop is very recent, I think the hardware
is not supported well. But I would like your advice, perhaps I can do
something to get a working setup.
