Followup. This morning's updates brought the missing kernel in, and I
installed it. I now have two kernels of what apprear to be the same
major, minor and patch numbers on my system:
kernel-2.6.19-1.2911.6.4.fc6.i686
kernel-2.6.19-1.2911.fc6.i686
Huh?
I went ahead with the normal stuff to get the driver enabled. Running
glxgears indicated that the system now runs slower than it did before
I installed the driver. Again, Huh?
I finally rebooted. On the way up, the system locked up. I rebooted
again. The system came up, and glxgears reports speeds ranging between
500 and 1000 fps, not exactly a steady rate. However, GoogleEarth now
works at a reasonable rate.
Even though glxgears is not a benchmarking tool, you should let it sit
and it will eventually give a steady framerate. If there are problems
in 3D acceleration with a closed source driver from a third party
repository then those problems should be addressed with the proper
people. Fedora in general really has no say in these matters.
* Why is a reboot necessary to install a driver module? Why are two
reboots necessary to install a driver module? This is not Windows.
A reboot is typically not necessary to install a module. However if
that module is linked to a specific kernel version, then you must be
booted into *that* specific kernel to use (load) it. Since there is no
way to restart a kernel, any kernel update will require a reboot to
start that kernel.
Some kernel modules don't work well being inserted into and removed
from the running kernel. Some can't be removed at all once inserted
without a reboot. Considering you are using a propreitary closed
source kernel module and with the limited information you provided, it
is hard to say whether or not all of your reboots were entirely
necessary.
* Why do I need what appears to be two different installations of the
same kernel on my system?
These are 2 different kernels:
kernel-2.6.19-1.2911.fc6 was released Feb 13 (based on 2.6.19.3)
kernel-2.6.19-1.2911.6.4.fc6 was released Mar 2 (based on 2.6.19.5)
You don't need both of them. You 'yum' installed them. Typically more
than 1 kernel is left when using yum like this. Eventually old kernels
get removed.
I'm getting irritated at Fedora being a bit too bleeding edge for my
taste. I have work to do, and can't afford the time I spend farting
around with this stuff. Maybe I should join Mr. Raymond over at
Ubuntu.
It would appear from your previous email that the livna repository had
already synced and recompiled to 2.6.19-1.2911.6.4. Apparently the
particular fedora mirror you were using was out of sync. There will
always be lags in syncing mirrors.
I like Ubuntu. It is a fine distribution. If it better suits your
needs, by all means, please do use it.
