Navigation by keyboard in nautilus on Fedora 18 ( Gnome 3.6 )

In the former Gnome releases of Nautilus, I was used to use "backspace" to go up a directory.

When typing a name in a nautilus window, the visible items are narrowed
down to suitable names/folders.

After selecting wit the cursor keys and pressing <enter>, the directory is changed.

But I didn't know how to go one directory up with the keyboard. Now, I found a hint in an ubuntu forum.

The key's are <alt>-<cursor up/down/left/right>.

Something different, I have to become comfortable with, but it works.

Improving start performance of apps in Fedora 18 with the preload service

Last week I have red somewhere, to improve startup performance of
often used applications by installing preload and starting the service.

The last few days I've seen that the service is starting apps a lot faster.

yum install preload 

systemctl start preload

systemctl status preload
preload.service - LSB: Adaptive readahead daemon
      Loaded: loaded (/etc/rc.d/init.d/preload)
      Active: active (running) since Fri 2013-02-08 22:15:57 CET; 22min ago
     Process: 1280 ExecStart=/etc/rc.d/init.d/preload start (code=exited, status=0/SUCCESS)
      CGroup: name=systemd:/system/preload.service
          └─1296 /usr/sbin/preload --verbose 1

Updated to LibreOffice 4.0 in my Fedora 18

This week LibreOffice release version 4.0.

After downloading, the archive can be extracted.

I uninstalled the 3.6 version, which I installed manually by

for d in `rpm -q -a | grep libre`; do
rpm -e --nodeps $d

After this the installation worked with

sudo yum install *.rpm
cd desktop-integration
sudo yum install *freedesktop*.rpm

Update Fedora 18 to kernel 3.7.6 let fail to install NVidia 310.32 driver

Today I updated my Fedora 18 system and the update installed kernel 3.7.6
into the system.

After rebooting, I have to install the NVidia driver again. The current version is 310.32.

But the install-Script fails to recoginze the kernel sources.

I found a hint here, what the problem could be.

After extracting the NVidia-Driver with

./NVIDIA-Linux-x86_64-310.32 -x

cd NVIDIA-Linux-x86_64-310.32/kernel/

vi conftest.sh 

Search for PATCHLEVEL on line 1702, I commented some lines:

1705                 #if [ -n "$PATCHLEVEL" -a $PATCHLEVEL -ge 6 \
1706                  #       -a -n "$SUBLEVEL" -a $SUBLEVEL -le 5 ]; then
1707                     SELECTED_MAKEFILE=Makefile.kbuild
1708                     RET=0
1709                 #fi

as shown here.

After this


installs the driver and a reboot starts the NVidia driver again and shows the
Gnome3 Desktop.
