Eliminate gtk warnings

Friday, July 22, 2016 12:42 pm

The following post helped me out a lot this morning:


When executing the vmware workstation bundle, the following gtk2 errors are displayed:

Extracting VMware Installer…done.
Gtk-Message: Failed to load module “pk-gtk-module”: libpk-gtk-module.so: cannot open shared object file: No such file or directory
Gtk-Message: Failed to load module “canberra-gtk-module”: libcanberra-gtk-module.so: cannot open shared object file: No such file or directory


Create a gtk2 configuration file and reload libraries.

~]# echo “/usr/lib64/gtk-2.0/modules” > /etc/ld.so.conf.d/gtk2.conf

~]# ldconfig


The installer should run without gtk2 errors.

Intel Graphics for CentOS 6

Thursday, October 15, 2015 3:09 pm

Recently, I started seeing error messages regarding many bad sectors in the hard drive in my HP laptop. After looking at various websites I determined that it wouldn’t be a bad idea to purchase a new hard drive as opposed to trying to fix this issue with disk utilities. 

After purchasing and installing the new hard drive, I had to install CentOS again. One thing I quickly noticed is that the default Installer did not seem to work so I tried “Install with basic video driver”. Long story short, after doing the install with the basic video driver I had to do 2 things to enable CentOS to use the Intel graphics card.  

1. Edit the /etc/X11/xorg.conf file replacing the word “vesa” with “intel”
2. Edit the /boot/grub/menu.lst file by removing the word “nomodeset”
