I had a broken hdd in my laptop 2 days ago. It made me to decide to find another hdd and install my Linux Backbox into it. Something made me worry, I forgot how to set the monitor to the appropriate setting. Then I had to browse the google once more. Here is what I looked for : sis671 driver for my 64bit Backbox.

I manage to find them. Cause I still keep those two in my own repo driver. I copy them to

#sudo cp sis671.la  /usr/lib/xorg/modules/driver
#sudo cp sis671.so  /usr/lib/xorg/modules/driver

Then Everything not goin right. I still have the 480×600 resolution. Then I went to grub setting at boot. I put vga=791 to force the display resolution up. It worked. But I didn’t satisfied, it should not be stop at 1024×768. Before this I manage to have 1280×768. Just I forgot how.

Then Googling again and find out about edid.bin. Actually just a blind guess, cause the source said it was used for nvida driver not my sis671. But what the hell. And sorry source, I forgot to write down your address. I tried to search you again in my history chrome but hell, that’s a lot of them so naaaaaaaa I’ll find you later.

According to the source I copied the edid.bin file to /root. Cause it goes to a reference in xorg.conf. And I also copied the xorg.conf but I modified myself cause it is not nvidia but sis. I will use sis671 driver that I copied earlier.

 

Here is my xorg.conf

Then Reboot.

Oh pay attention to the modeline line in the xorg. I change the original one to my setting. The how to get the modeline is through this command.

#cvt 1280 768

The result will be like this :

# 1280×768 59.87 Hz (CVT) hsync: 47.78 kHz; pclk: 79.50 MHz
Modeline “1280x768_60.00” 79.50 1280 1344 1472 1664 768 771 781 798 -hsync +vsync

Copy and put the result into the xorg.conf. Then reboot again. And my laptop is fine now.

Oh just for the record, not for publishing reason, I didn’t get paid anyway from the manufacturer, I use Axioo Neon MNC 215p.
