How to change screen resolution

[Triadi Krisnawan]

Hi Doc,
 
Thanks for the info.
I think I could take off the first posibility because it was working fine before with higher resolution 4 weeks ago. But after I rebooted the machine went to lower resolution (1024x768) and started flickering. So the KVM might not be the problem.
 
I will try to use the gft command. I am assuming that this command can run in any terminal right?
And also which are the two lines to be copy?
Are they : 
1280x1024 @ 60.00 Hz (GTF) hsync: 63.60 kHz; pclk: 108.88 MHz
Modeline "1280x1024_60.00" 108.88 1280 1360 1496 1712 1024 1025

Or 
Modeline "1280x1024_60.00" 108.88 1280 1360 1496 1712 1024 1025
1028 1060 -HSync +Vsync
 
Thanks Doc,
Triadi
