Some ASUS UL80VT Problem Solved

When i bought this laptop (ASUS UL80VT), i never thought it would have problem with Linux, mostly about the dual VGA Card. The brightness key combination didn't work also (it worked out of the box on my previous ACER laptop).

Thanks to Ubuntu team and also member of asus-ul30 mailing list who work together to collect DSDT from other people who have hybrid graphic cards as well and analyze them, i now able to set my brightness and disable NVidia card temporarily to boot my battery life much longer than before.

To set the brightness, you can just use xbacklight command from xbacklight package, included on Slackware's default package on x/ directory. I used this two scripts on my laptop
#!/bin/sh
xbacklight -inc 10


#!/bin/sh
xbacklight -dec 10

Give them light-up and light-down and put them on some place on your PATH. I used /usr/local/bin, since it's my own scripts. Don't forget to give execute permission by running chmod +x /usr/local/bin/light-*. To make it easier for you to change the brightness settings, i made a shortcut using KDE's Input Keys so that i don't have to open a terminal.

To set the default brightness everytime i started my KDE, i used this script
#!/bin/sh
LCD_DEFAULT=10
LCD_STEP=10
case $1 in
default) xbacklight -set $LCD_DEFAULT;;
up) xbacklight -inc $LCD_STEP;;
down) xbacklight -dec $LCD_STEP;;
*) xbacklight -set $LCD_DEFAULT;;
esac


About switching off the NVidia card, you can see the script on this blog.

With these problems solved, the only things that bother me is how to use NVidia card instead of Intel. I wanted to enjoy the beautiful KDE effects on my laptop. I'm waiting for that moment to come Gym

Running Rsync Via Proxy

One way to get the latest Slackware updates is by running rsync to syncronize your local repository and the main repository that hold the Slackware packages. Eric Hameleers has provided a great script called rsync_current.sh and how i modified this tool has been discussed on my previous post. In general, it works, except for one problem, when your computer is connecting to the Internet through a proxy.

My workstation at my office is connected to the Internet through a proxy, so i can't use normal rsync to work normally. I browsed the web and i found this site which tells us about how we should modify our squid configuration to allow rsync connection from any computer from our local networks. I asked my sysadmin to try this script. He agreed and he updated the squid configuration on the proxy.

Next, i need to update my environment variable RSYNC_PROXY to the host of the proxy and also the port. Let's say you are running a proxy on 192.168.1.1 and port 8080, then you need to run …

NVidia Legacy Unix Driver Update

NVidia has released an updated legacy drivers to support X.Org 1.19 with ABI 23. It has been mentioned in the UNIX drivers, but you can directly find the drivers from the links below:
NVidia 304.134 (x86x86_64)NVidia 340.101 (x86, x86_64) I have tested the 304.134 driver and it's working great here. I can finally remove x from my /etc/slackpkg/blacklist file since it's a showstopper for me.
Aside from legacy driver, NVidia has also released their latest driver 375.26 (x86, x86_64), which brings support for newer cards and also many new features (including X.Org 1.19 with ABI 23 support).
