Google Earth

I installed the x86_64 version of the Google Earth rpm. It did however not work:

$ google-earth /usr/bin/google-earth: ./googleearth-bin: /lib/ld-lsb.so.3: bad ELF interpreter: No such file or directory

Turns out the provided binary is in fact not 64-bit:

$ file /opt/google/earth/free/googleearth-bin /opt/google/earth/free/googleearth-bin: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.15, stripped

Installing the package redhat-lsb.i686 fixed it:

yum install redhat-lsb.i686

Power Saving – This helps a lot on laptop batteries!

Add the following lines to /etc/rc.d/rc.local

modprobe cpufreq_powersave
cpufreq-selector -g powersave

Add to the desktop panel (top bar)

CPU Frequency Scaling Monitor

Install Xine to play DVDs

Create/edit /etc/yum.repos.d/atrpms.repo

Enjoy

Requires: libvpx.so.1()(64bit)

If you get the error message:

Error: Package: libavcodec53-0.10-54.el6.x86_64 (atrpms)
           Requires: libvpx.so.1()(64bit)
 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

You did not set up the repo file correctly above

Install hangs on “Scanning storage” when using a SSD drive

I added irqpoll kernel parameters on boot and everything is now fine. Make sure you modify grub after you install Centos to make sure that parameter is kept.

I installed vbetool by downloading vbetool-1.2.2-1.fc12.src.rpm and rebuilding it. vbetool does not come with Centos 6.

You will need EPEL to build vbetool (see above Additional Package Sources)

To install

su -
(download vbetool srpm)
(install EPEL)
yum -y groupinstall "development tools"
rpm -Uvh vbetool-1.2.2-1.fc12.src.rpm
yum -y install zlib-devel libx86-devel libpciaccess-devel
cd ~/rpmbuild/SPECS
rpmbuild -ba vbetool.spec
cd ~/rpmbuild/RPMS/x86_64
rpm -Uvh vbetool-1.2.2-1.el6.x86_64.rpm

reboot computer (although, logging off and logging back on may do the trick)

Broadcom Wireless Card

reference: http://elrepo.org/tiki/wl-kmod

You cannot compile http://www.broadcom.com/support/802.11/linux_sta.php on Centos 6.3. You get all sorts of interesting errors. The following does work.

1) Install needed tools/packages:

# yum groupinstall 'Development Tools'
# yum install redhat-lsb
# yum install kernel-devel-$(uname -r)

2) As a regular user (not as root), configure a build tree and minimal .rpmmacros:

$ mkdir -p ~/rpmbuild/{BUILD,RPMS,SPECS,SOURCES,SRPMS}
$ echo -e "%_topdir $(echo $HOME)/rpmbuild\n%dist .el$(lsb_release -s -r|cut -d"." -f1).local" >> ~/.rpmmacros

3) Download wl-kmod*nosrc.rpm

For EL5: http://elrepo.org/linux/elrepo/el5/SRPMS/wl-kmod-5_100_82_112-3.el5.elrepo.nosrc.rpm
For EL6.2 and earlier: http://elrepo.org/linux/elrepo/el6/SRPMS/wl-kmod-5_100_82_112-3.el6.elrepo.nosrc.rpm
For EL6.3 and later: http://elrepo.org/linux/elrepo/el6/SRPMS/wl-kmod-5_100_82_112-4.el6.elrepo.nosrc.rpm

4) Download the Broadcom driver matching your architecture (i.e., 32-bit vs 64-bit):

From: http://www.broadcom.com/support/802.11/linux_sta.php (external link)
to: ~/rpmbuild/SOURCES/
5) Build kmod-wl as a regular user (not as root):

$ rpmbuild --rebuild --target=`uname -m` --define 'packager <your-name>' /<path-to-nosrc.rpm>/wl-kmod*nosrc.rpm
...
Wrote: /home/<user>/rpmbuild/RPMS/x86_64/kmod-wl-<version>.x86_64.rpm
...
+ exit 0
(Note: The rpmbuild option --target=`uname -m` is only required for EL5 32-bit builds.)

6) If ndiswrapper is installed and is no longer needed, then remove it:

    # yum remove \*ndiswrapper\*

7) Install kmod-wl:

  # rpm -Uvh /<path-to-rpm>/kmod-wl*rpm
  OR
  # yum --nogpgcheck localinstall /<path-to-rpm>/kmod-wl*rpm

8) Reboot or to start wireless now:

8a) EL5:

  • Works immediately after installation without intervention

8b) EL6:

    # modprobe -r b43 b43legacy ssb wl lib80211
    # modprobe lib80211_crypt_tkip
    # modprobe wl

9) Store kmod-wl*rpm for safe keeping
10) Optional – Remove build tree (and the kmod-wl binary you just built): (I would leave it in case you update the kernel)

  $ rm -rf ~/rpmbuild
