After a good experience with Fedora Core 8, and a reasonable experience with Fedora Core 11, I decided to install Fedora Core 12 on my Chembook laptop.
In summary, while FC8 and FC11 worked out of the box, FC12 failed to provide me with sound. I discovered later that the KDE mixer had set the center volume to mute. Once I unset that, I had sound.
Other than that, it worked pretty well.
RedHat Linux was the first distro I ever worked with, and I got very used to KDE. After that I moved onto Fedora, always using KDE, and have not felt any need to change. However, KDE 4 seems over-designed.
I ran a final backup of my data to an external USB drive, and then performed a full installation from the FC12 i386 DVD (but without installing the gnome desktop manager). I completely formatted the drive during the process. Once the installation completed, the first thing I did was to restore my data to the laptop.
There were some specific issues I needed to fix before I was happy with FC12.
Monitor resolution and xrandr
I normally have an LCD monitor connected to my laptop, and when it is connected I don’t use the laptop screen i.e. I don’t use it in a dual-head mode. So I wanted FC12 to automatically disable the LVDS display — but only when the monitor was connected. I tried selecting this option System Settings -> Display, but the settings never stuck.
I had come across something similar with FC11, so I resorted to manually invoking xrandr at the startup of X:
[philip@localhost xdm]$ tail -n 14 /etc/X11/xdm/Xsetup_0
# Force the screen to a resolution my Compaq Q2159 supports -- but only if it
# is connected.
/usr/bin/xrandr | grep "$EXTERNAL_OUTPUT connected"
if [ $? -eq 0 ]; then
/usr/bin/xrandr --output $INTERNAL_OUTPUT --same-as $EXTERNAL_OUTPUT
/usr/bin/xrandr --output $INTERNAL_OUTPUT --off
# Fedora 12 sets the right resolution
#/usr/bin/xrandr --output $EXTERNAL_OUTPUT --mode $MODE --rate $RATE
Keyboard shortcuts and xbindkeys
khotkeys allows you to override the default key bindings in KDE (e.g. F5 to refresh) and set your own custom actions. For example I always use F5 to launch a shell. Well, khotkeys is completely broken in FC12 — it simply doesn’t work and the keys always retain their default binding.
I needed a replacement so I came across xbindeys. This is a great tool which works exactly as promised. FC12 didn’t install it by default, but you can install it like so:
yum install xbindkeys
Once installed, a particularly useful option is
This pops up a window, allowing you to press a key. xbindkeys will then spit out the code for that key, which you can then add to its configuration file, along with the desired command.
To autostart it, I simply added it to System Settings -> Advanced -> Autostart.
The system tray
This was, by far, the most annoying problem.
When FC12 first ran, the System Tray was OK. It showed the Volume control, as well as the NetworkManager applet. But somehow I removed the NetworkManager applet from the tray, and could not get it back. Furthermore, I could not add any other icons to the tray. Even setting the Visibility preferences for all icons to “Always Visible” made no difference.
This seems to be a bug — I came across other reports on the web about this. After about an hour I gave up, dropped to run level 3, and moved my KDE configuration directory out of the way:
mv ~/.kde/shared/config ~/.kde/shared/config.orig
I then restarted KDE by going back to run level 5. KDE then regenerated this directory. I had to redo my KDE settings, but the tray was back to normal.
The kernel configuration file is here.
