The first beta of the elementary OS Freya became available not so long time ago, and I’ve decided to give it a try. It replaced Ubuntu on my HP notebook, and the result was altogether positive, especially for a software which is in the beta phase.
There was one annoying problem though: although I have no secondary display connected, it got automatically enabled. I could disable it in the control panel, but after the reboot, it got enabled again. The result of this was a flickering mouse cursor, which could escape to the wast invisible area where the secondary display supposed to be.
To be fair, I had a problem of this nature in Ubuntu too though there, once I disabled it, the setting sticked through reboots.
To overcome this on elementary OS, I’ve created
xorg.confg file and set the secondary display to be ignored.
First, I’ve grabbed a display ID:
$ xrandr | grep " connected"
In my case the ID was
/etc/X11/xorg.cong file, with the following content:
Section "Monitor": Identifier "LVDS-1-1" Option "Ignore" "true" EndSection
After this, as it would be expected, the secondary display completely disappeared from the control panel.
