The Acer TravelMate B115-M is available in various configurations. According to my retailer, my system's full model name is "Acer TravelMate B115-M-41RQ"; I can't find this exact model name listed on Acer's website, but it does show a Acer Travelmate B115-M NX.VA1EG.002 with mostly matching specifications.

The computer has no DVD drive, so to install openSUSE 13.2 I used an external USB drive. I had YaST completely wipe and repartition the hard drive, but apart from this used all the default settings. The installation appeared to complete successfully, but upon restarting, the computer didn't recognize the hard drive as bootable, giving me a message to the effect of "No bootable devices found".
The problem turned out to be that the hard disk had the
set. This flag prevents the computer's UEFI system from scanning the
disk for EFI boot partitions. (See openSUSE Bug
932033.) I have
no idea whether the flag was already there when I got the machine, or
whether it's something the openSUSE installer added, but in any case it
shouldn't be there for a successful UEFI boot.
If you encounter this problem, you can fix it by using the openSUSE
installation disk to boot into Rescue Mode and then use
# parted /dev/sda (parted) disk_set pmbr_boot off (parted) quit
Most components and features work out of the box. Here is a description of some components with special considerations, or which I have not yet gotten to work.
The touchpad does not have separate left and right buttons; instead you can left click by pressing the lower left corner of the touchpad, and right click by pressing the lower right corner. It is not possible to press both corners at the same time, which means that the usual way of simulating a middle click (i.e., the third mouse button) does not work.
However, there is another way of producing left, right, and middle clicks which works out of the box:
This behaviour can be customized in KDE using the "Input devices" module of the Control Center.
Contrary to reports I have seen online for other GNU/Linux distributions, on openSUSE 13.2 most of the special Fn+key combinations (including the Fn+Left and Fn+Right combinations for adjusting the display brightness) work out of the box. The only exception I've discovered so far is Fn+F3, which is supposed to disable wireless—this doesn't work, though I can still disable wireless on the command line or using the KDE network manager plasmoid.
To set up a keyboard shortcut for toggling wireless (i.e., airplane mode), create a script with the following contents:
1 2 3 4 5 6 7 8 9
#!/bin/bash wifi="$(nmcli r wifi)" if [ "$wifi" = "enabled" ]; then nmcli r wifi off else nmcli r wifi on fi
Make sure you set the script as executable. You can then create a menu entry for this script in your desktop environment and bind a shortcut key combination to it. Unfortunately, it's not possible to use Fn+F3, or any other Fn combination, as the keyboard shortcut; this is most likely a problem with the keyboard driver used by the kernel. (See this discussion on the X.Org bug tracker for details.) I used Meta+F3 (where "Meta" is the key with the Windows logo).
