Ubuntu on the Acer Aspire E15 (E5-571G-51TH)

Having failed the 3rd repair attempt at the Thinkpad E540 [1] I gave up and bought the next best laptop from the nearby store that somehow is usable for programming. Behold: the Acter Inspire E15. 8GB RAM, i5, matte screen (1920×1080). It worked out of the box with the SSD transplant from the old Lenovo, so the Aspire gets a check for Ubuntu 14.04 LTS compatibility.

[update 2015-07-01] There is a serious problem with rendering text [2], I’m currently looking into it. Fixing requires creating the file /usr/share/X11/xorg.conf.d/20-intel.conf:

Section "Device"
        Identifier "Intel Graphics"
        Driver "intel"
        Option "AccelMethod" "uxa"
        Option "DRI" "true"
        Option "TearFree" "true"

The E15 is another laptop with a hybrid Intel/nvidia graphics system. The bad news is that I couldn’t get bumblebee running so far, so I can’t use the nvidia card. The good news is that the default Intel graphics system is fast enough to play Civilization V at the maximum resolution and the laptop stays pleasantly cool. So, in a weird way, that’s quite an improvement over my previous laptops.
