Set proper resolution for monitor


Hello, Everyone:

I have been searching around online for a solution to my monitor resolution problem, but I see some answers that work for some, and other answers that may or may not work for others, and I fear that if I begin trying to tinker around with something with any/all of these answers, I will screw something up. Hence, I come to this forum with a new thread and ask basically the same question I have seen elsewhere online, i.e.--my monitor is a 20" HP S2031 capable of 1600 X 900 resolution, which I would like to set it to. However, that resolution is not available in the list whereby I may set it to that resolution. Will someone help me by walking me through the proper change to the proper file in order for my monitor to render the proper resolution, please?

Much thanks,
theAdmiral

What gpu are you on and which driver handles it?
For the first part look in
Code:
lspci | grep VGA
and for the second one in
Code:
lspci -k
under the card found previously.

For instance
Code:
01:00.0 VGA compatible controller: NVIDIA Corporation G70 [GeForce 7800 GTX] (rev a1)
	Subsystem: XFX Pine Group Inc. Device 2180
	Kernel driver in use: nvidia

john@debian:~$ lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation Sandy Bridge Integrated Graphics Controller (rev 09)
And for the second one, I couldn't find a "kernel driver in use", probably 'cuz I didn't know what to look for. So I posted the entire output:

Well, it seems you are using the vesa driver for your gpu, which means limited capabilities.
Are you on debian stable? If so, please move to testing or unstable so as to get a newer xorg and kernel (and a newer intel driver as a result) which will support your gpu.

I have an 8-DVD package of Debian 6.0.6 (stable, I assume) that I ordered from ShopLinuxOnline. I recently installed it and updated the OS to 6.0.7. Does moving "to testing" mean I have to install a different version? Or can I perform this by command line? What does it mean to "move to testing"? Why is it called "testing"? Is it any less stable (performance-wise) that "stable"?

If the answers to these questions lend themselves to the installation of an OS that is no more likely to crash than "stable", then how do I "move to testing"? At this time I would rather give some time to consider reinstalling than jump straight to installing "testing", and instead put up with the annoyingly odd resolution for now.

Thanks again for your continued help.

Hi,

I think you can stick with stable if you use a newer kernel from backports (for many people it's best to avoid run testing and/or unstable). See for example

HTH,

Evo2.
