855resolution

1280x768

Linux (Ubuntu)

Averatec 1050

02/17/2006

Here is how I was able to get the 1280x768 resolution to wok on my Averatec 1050 running Ubuntu Linux. I am not very good at Linux so it was a hassle for me to figure this out ... so I am hoping this will help at least one person out there.

Step one:

Download the 855resolution tar file: http://perso.wanadoo.fr/apoirier/

(Thank you Mr. Poirier!!!!)

unzip, untar, make, make install

Follow his instructions to replace one of your unused modelines with 1280x768 (or what ever resolution you are shooting for). Here is an example. Typing '855resolution -l' gives your modes. In my case the 3c line was NOT 1280x768 like it shows here:

Mode 7d : 1280x768, 16 bits/pixel

Mode 7e : 1280x768, 32 bits/pixel

To get that 3c line to read my desired 1280x768, one uses the command:

855resolution 3c 1280 768

The problem is that this modification only holds until you reboot. So, you have to run this command each and every time you reboot. Create a script called 855start that contains the following single line:

855resolution 3c 1280 768

Now put this script in /etc/init.d and chmod +x it. For some reason, I next ran:

update-rc.d 855start defaults 80

Now, 855start will run when you reboot ... but will it run at the right time. This is where the sage advice of “wildcard” comes in. See his post at http://ubuntuforums.org/showthread.php?t=24923

This was huge for me. Following his instructions, cd to /etc/rc.d. type dir. Find SXX855start where XX is a two digit number. Find also SYYgdm. You have have XX < YY. For me, my XX was 80 (because of the update-rc.d command I ran) and my YY was 13. That is, I had S80855start and S13gdm. I also had no numbers S06--- to S10---. So, doing as wildcard did, I copied S80855start to S09855start.

Almost there ...

Just need to modify xorg.conf. Here is mine.

In case you need the 855resolution that I used, here is mine ...

sha1sum is;
