One of the main driver things that I have to install is the video card. My laptop has a discrete video card. Without installing the driver, the graphics seem to work pretty well, but with the driver, I get a very noticeable improvement in power consumption. After installing the driver, the battery lasts significantly longer. Also, glxspheres does a nice job of showing the graphics performance difference with and without the acceleration.
I originally published this script on my PeopleSoft Blog, but since it is as much Linux related, I thought it should go here, too.
The problem was that I was trying to install the Oracle Database via SSH using the GUI installer. The sudo command was breaking my X11 forwarding.
I found the answer on the “Bag of Tricks” blog:
Here’s my version:
if [ -z "$user" ]; then
displayNum=`echo $DISPLAY | sed -e ‘s/^.*://’ -e ‘s/\.*//’`
echo "Display # = $displayNum"
cookie=`xauth list | grep ":$displayNum"`
echo "Cookie = $cookie"
cookiename=`echo $cookie | sed ‘s/\s*MIT-MAGIC.*$//’`
echo "Cookie Name: $cookiename"
echo "user = $user"
sudo -u $user bash -c "xauth list; xauth add $cookie; bash; xauth remove $cookiename"
