I’ve had a number of major issues with Ubuntu 17.10 (Artful Aardvark). I thought I would catalog them and I’ll update as I find out more. Please comment if you find solutions!
Ubuntu 12.10 and Discrete Video Card
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.
Sudo Plus X11 Forwarding
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:
Bag of Tricks: x forwarding and sudo for oracle installs
Here’s my version:
#!/bin/sh user=$1 if [ -z "$user" ]; then user=<default user> fi 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"
