    Hi, new to Linux and Elementary OS, recently installed on both my desktop and laptop. Desktop installation smooth and performance perfect. Laptop installation had issues, kept failing. Eventually got it to work (I think the acpi = off worked) but the graphics performance is poor. (I think wifi may be poor as well - seems very intermitent).. There is a noticeable lag when moving things around the screen, a lot of screen tearing, choppy animations, videos play poorly in 1080p full screen, and also some visual defects eg in the photo, here the cursor was still. This is chromium but the issue seems to be widespread across apps. The laptop is the following:

    Asus UX305CA
    m3 0.90 Ghz dual core
    8GB ram
    Intel Sky Lake Integrated Graphics

    *-display
    description: VGA compatible controller
    product: Sky Lake Integrated Graphics
    vendor: Intel Corporation
    physical id: 2
    bus info: pci@0000:00:02.0
    version: 07
    width: 64 bits
    clock: 33MHz
    capabilities: pciexpress msi pm vga_controller bus_master cap_list rom
    configuration: driver=i915 latency=0
    resources: irq:124 memory:de000000-deffffff memory:c0000000-cfffffff ioport:f000(size=64) memory:c0000-dffff


    The display is 3200 x 1800 so I have had to adjust scaling, and I have also installed tweaks and a different theme...

    I didn't have any graphics issues on windows 10 prior to installing eOS

    Any help much appreicated !

    Try with
    Code (Text):
    sudo nano
    /etc/X11/xorg.conf.d/20-intel-graphics.conf
     
    add following:

    Section "Device"
    Identifier "Intel Graphics"
    Driver "intel"
    Option "TripleBuffer" "true"
    Option "TearFree" "true"
    Option "DRI" "false"
    EndSection


    <ctrl>+<o> : save
    <ctrl>+<x>: exit

    reboot.

    ØYou could also try the latest mesa driver: https://www.omgubuntu.co.uk/2017/11/install-mesa-17-2-ubuntu

    Thank you for your response. Not sure if I did it wrong.. when I went into nano and tried to open that file it said no such file exists so I created one with the settings you mention.. and it made the problem a lot worse!! Everything became very glitchy and laggy. I looked online and tried playing with some other options eg "DRI" "true" but not much luck ... and more advice? thank you!

    I don't have more advise other than updating mesa driver (intel driver) or wait for eos Juno gets released. I'm a nvidia guy, I only run nvidia cards so my knowledge regarding intel is very small.
