Hello!
Bit of a newbie to the forum here. A few months ago, I received an Acer Aspire 3 laptop and have been attempting to setup dual-boot with Windows 10 and Debian on it.
Before the X Window System would load, however, and to the fix the Ethernet & WiFi issues, I had to boot with "nomodeset" to get to a console in order to install firmware-linux, firmware-realtek and firmware-iwlwifi.
Once I finally got up and running, I would get continuous crashes while running video and other issues related to sleep/hibernation. I eventually gave up looking for solutions to these problems and thought I'd wait until Debian 10 was released and start from scratch.
From a clean install of Debian 10, X is now very broken. Clicking on the file manager, the frame of the window loads and then maybe 3 minutes later, the folder icons appear. If I try to move or close the window, it's delayed for several more minutes. After a few more minutes, the lock screen will appear but it is not possible to log back in and the screen just goes black after clicking the mouse, forcing me to reboot (which I must do with the power button because "sudo reboot" in the ctrl-alt-f1 console doesn't work either. And yes, I disabled 'turn on fast startup' in Windows).
I assume this is just more of the same - "linux amd video drivers, blah, blah, blah" - but that, combined with the buggy UEFI (I've installed the latest BIOS update from Acer released last month), the sleep/hibernation/reboot issues and other firmware problems has lead me to the tl;dr version: this laptop is not suitable for Debian.
