1.1 Desired screen resolution not detected

Related bug: https://bugzilla.redhat.com/show_bug.cgi?id=1339930

Manually add a resolution:

$ cvt 1366 768
# 1368x768 59.88 Hz (CVT) hsync: 47.79 kHz; pclk: 85.25 MHz
Modeline "1368x768_60.00"   85.25  1368 1440 1576 1784  768 771 781 798 -hsync +vsync
$ xrandr --newmode "1368x768_60.00"   85.25  1368 1440 1576 1784  768 771 781 798 -hsync +vsync
$ xrandr --addmode eDP-1 1368x768_60.00
$ xrandr --output eDP-1 --mode 1368x768_60.00

To add an undetected resolution permanently, create a configuration file /etc/X11/xorg.conf.d/10-monitor.conf:

Section "Monitor"
    Identifier "eDP-1"
    Modeline "1368x768_60.00"   85.25  1368 1440 1576 1784  768 771 781 798 -hsync +vsync
    Option "PreferredMode" "1368x768_60.00"
EndSection

Section "Screen"
    Identifier "Primary Screen"
    Monitor "eDP-1"
    DefaultDepth 24
    SubSection "Display"
        Modes "1368x768_60.00"
    EndSubSection
EndSection

Section "Device"
    Identifier "Primary Device"
    Driver "intel"
EndSection

2.1 tint2 not working for Wayland windows

Related bugs:

• https://gitlab.com/o9000/tint2/issues/609
• https://gitlab.com/o9000/tint2/issues/627

Workaround: Don’t run GNOME on Wayland yet.

3.1 Tracker is a CPU (and disk) hog

Terminate all running Tracker processes:

$ tracker daemon -t

Disable Tracker processes on startup and clean its cache:

$ cd ~/.config/autostart
$ cp -v /etc/xdg/autostart/tracker-* ./
$ for FILE in tracker-*.desktop ; do echo Hidden=true >> $FILE; done
$ rm -rf ~/.cache/tracker ~/.local/share/tracker

Furthermore, change all relevant lines in tracker-*.desktop to something like

X-GNOME-Autostart-enabled=false

However, tracker-store seems tenacious and will start on next boot anyway.
