Review of Linux Compatibility

The Lenovo A740 is a 27 inch Desktop PC and was successfully tested under Ubuntu 16.04.1 LTS with Linux kernel version 4.4.0-51-generic.

The Lenovo A740 requires the boot option “acpi=noirq” for its kernel, i.e. /etc/default/grub needs

GRUB_CMDLINE_LINUX=”noprompt persistent acpi=noirq”

to boot and reboot.

The internal WiFi works when using the driver from https://github.com/lwfinger/rtl8723au.

    Hi,

    I’ve been trying to install linux in my Lenovo A740 (the same model you’re reviewing), but unsuccessfully. I’ve tinkered with UEFI settings and I’ve been able to boot from a USB with Ubuntu 16.04 and select the option to install. It starts but then fails with the message “unable to find any live system”.

    Did you face the same problem when installing? Do you know how to solve it or at least could you give me a pointer to a solution?

    Thanks!

    • Sam says:

      Struggling with the same issue. I was able to successfully boot a live USB stick with Ubuntu 14.something, but nothing else.
