THIS PAGE IS STILL INCOMPLETE

Intro

After two years with FC3 I decided it would be time for a fresh install.

Download

I downloaded FC6 the day it went public via the Bittorrent link (as everyone knows, the website went down immediately before the public release). Took me an overnight download at roughly 120 kBit/sec, not fast, but it worked.

Basic install

Basic installation of Fedora Core is painless. I decided to get rid of the tangled mess that was my FC3 installation and did a backup of my /home directories and manually installed files (most of them conveniently stored in a top-level-folder called /tuxprog).

I did not format the hard-disk, but deleted just everything I did not need any longer (old system files).

To do so, boot from the FC6-DVD, enter

linux rescue

at the prompt, select your keyboard, do NOT mount the existing system, but do so manually afterwards with

mkdir /mnt/sda2
mount /dev/sda2 /mnt/sda2

(or whatever the partition is named, where you main system resides). The reason for this is, that the rescue system mounts the partition in a way that prohibits deletion of the /sys and /selinux directories.

Delete everything except the stuff you want to keep (with one external backup I always have two copies of my home files in this way, nice if your backup-disk decides to die the day you do the update). The alternative would be to have a second backup of course (I don't have that).

Reboot and do a normal install. Do NOT repartition the disk, but reuse the existing partitions. Select repositories and packages as appropriate.

Tweaking

As usual, some things did not work, most annoyingly the heavily advertised AIGLX based eye-candy. Below is an installation instruction for nVidia + Compiz which worked for me. After fumbling around with the new system for some time, I became convinced, that 3D-effects are a "bit" immature, and should be switched of (see below for details).

nVidia beta drivers

I followed the description on [1] to install the latest prepackaged nVidia beta drivers from livna.org, which worked fine.

Steps

Enable the livna repository
Enable livna-testing to get the unstable nvidia 1.0-9626 driver for FC6
Restart (unloading and reloading of the kernel module might help as well)

Commmands

>$ sudo rpm -ivh http://rpm.livna.org/livna-release-6.rpm
>$ sudo rpm --import http://rpm.livna.org/RPM-LIVNA-GPG-KEY
>$ yum install kmod-nvidia --enablerepo=livna-testing

In theory, now you can click on "Enable desktop effects" and things should work (wobbly windows, desktop cube, expose-like effects if you move your mouse to the upper right corner).

If not, read on:

My nVidia driver complained about

Q. My X server fails to start, and my X log file contains the error:
   
   (EE) NVIDIA(0): The interrupt for NVIDIA graphics device PCI:x:x:x
   (EE) NVIDIA(0):      appears to be edge-triggered. Please see the COMMON
   (EE) NVIDIA(0):      PROBLEMS section in the README for additional
   information.

fortunately this could be fixed by adding noapic to the kernel start arguments as advised in the README.txt file accompanying the nVidia driver. X started again. Still, enabling desktop effects did not work.

Add further parameters to /etc/X11/xorg.conf

- In Device

Option	    "AddARGBGLXVisuals" "True"

- and

Section "Extensions"

   Option "Composite" "Enable"

EndSection

at the end of the xorg.conf

Still no effects.

Doing a manual

>$ compiz --replace &

gave

compiz: No sync extension

According to a post on [2], this can be fixed by adding this to your Module section of xorg.conf:

SubSection "extmod"
Option "omit xfree86-dga" # don't initialise the DGA extension
EndSubSection

See http://rpm.livna.org/rlowiki/Packages/xorg-x11-drv-nvidia if you still run into trouble (should not be the case now).

Compiz problems

Compiz seems to be unstable, at least FC6 hung and had to be reset while starting totem once. In addition, I found, that OpenGL games tend to stutter, an effect, which has been reported by others as well.

Another anoyance is, that -after fideling around with xorg.conf settings, compiz refused to draw window-borders (again).

This could be fixed the hard way by simply deleting the compiz-preference in

rm -rf  .gconf/apps/compiz/

FC6 does not store session details by default (i.e. leaving for example a terminal open on log off would not open that terminal on next login at the same position and size again). This could be reenabled, but led to a black screen with a mouse-cursor on next login. Fun.

This could only be fixed by deleting the .gconf and .gconfd preferences.

So much for this, I will give it a try, but mostly I think I will stay with the default 2D-manager, which is rock-stable until the bugs have been ironed out.

CD-RW/DVD+-RW

FC3 had issues with my Plextor-PX712A, which would have been solved with the new FC6 install -or so I hoped.

You can imagine my joy, when I found out, that this was not the case. Still problems detecting DVDs (DVD-R and DVD-RW are detected most of the time though). I guess I will reopen that f*cking bug report on the FC6 bugzilla.

Video

I installed the standard totem and totem plugin for Firefox, but until now totem only managed to crash Firefox reproducibly or hang the entire system. Let's see what the sollution is here...

My opinion

Green! Very green. There has been a reason why they had to delay that release several times. And they should have delayed it even further I guess. At least Gnome has some new features FC3 was lacking and -if you disable compiz- the system seems to be on par with my old FC3 installation.
