screen is off vertically by a number of pixels


Hi guys,

I am completely a newbie to linux. Having recently installed puppy linux (pup431) on my sony pcg-c1mah laptop with a monitor of 1280x600, I am absolutely in love with it. It is so fast and smooth. However, there is one problem, the screen position is shifted up vertically, off by a few pixels (30 maybe). This makes most of the application partially off the screen, which is really annoying.
Previously, I was able to install xubuntu (8.04) on it without any problem. The screen was perfectly positioned. It was the speed reason I decided to go for puppy linux. If xubuntu was able to set the screen correctly, why puppy linux can not. I will be really appreciated if anyone can help me with this. Thanks in advance.

Jason

Try xvidtune
I had to use it on my old monitor. My win95 partition was fine but my slackware partition was way left.
Open a terminal in x and run xvidtune. It will give you a modeline you need to add to xorg.conf.
It is way easier than I make it sound. Google xvidtune and you will find examples.

Thanks for the reply.
I tried the xvidtune, however, it didn't allow me to change anything, such as pressing the test button, it gives me an error saying "You have requested a modeline that is not possible or supported by your hardware configuration.". Then, I tried to change edit /etc/X11/xorg.conf manually. Whatever I put into the file, nothing takes effect. Every time, I restart X it sticks with its original setting and screen problem persists. Any more advice?

Cheers
Jason

Have you tried generating a modeline with the `gtf' program?

Another thing to check is the HorizSync and VertRefresh lines in the Monitor section. The wrong values here can cause the correct resolution to not be available
