Acer P191W - Screen Resolution Problem

Hi Folks,

I am new to this forum and would very much appreciate some assistance with a problem I am experiencing. I’ve just made the move from Windows Vista back to Linux after about a three year break from it and I am having trouble configuring the correct screen res for my wide screen monitor.

Some basic info:

System: openSUSE 11.2
KDE: 4.3.5 (KDE 4.3.5)
Monitor: Acer P191W 1400x900
Graphics Card: NVIDIA geforce 6100 nforce 430

Everything appears stretched, wider than it should be. At first I couldn’t figure out how to change the screen res in Control Panel as it’s missing the Monitor option to amend anything. After some reading on another thread I managed to access it as su , sax2. It detects the correct Monitor Model but does not offer 1400x900 as a res option. I also tried selecting LCD instead of a make and then selected 1440x900 as there is no 1400 option but this doesn’t help things either.

I am a complete rookie so any help at all will be great. I thought it might perhaps be a driver issue as when windows are moved on the screen or if I scroll down a web page such as this it leaves ‘artifacts’. Has anyone else experienced similar problems?

Cheers,
James

Since you note you are new to openSUSE, you could start off reading this guide … In particular post#3: openSUSE Graphic Card Practical Theory Guide for Users - openSUSE Forums

can you also advise us as to what graphic driver you are using? Post#14 gives some guidance there (in particular look inside the file /var/log/Xorg.0.log ). I’m trying to find an easier way to determine this, but this far I have not found a reliable easier way.

Thank you for the fast reply. I will go and have a proper read of the thread you posted a link to in just a moment as it looks very interesting and is exactly the kind of thing I’ve been looking for all day.

First though, in answer to your question - After looking at ‘Xorg.0.log’ and ‘Xorg.conf’ it appears the Graphics Driver is ‘Vesa’ -

I’m trying to figure out if it’s better to try a different driver or maybe have a go at editing Xorg.conf as I have read of others managing to correct the resolution that way. The display besides being stretched wider than it should be also has other issues like videos appear very blue, text is not sharp etc

You should be able to do much better than just using the “vesa” driver.

I confess I am not familiar with the geforce 6100 nforce 430, but I would hope it is supported by the “nv” driver. It may also be supported by the proprietary “nvidia” driver. If you need any pointers on how to proceed after having read post#3 in the openSUSE Graphic card practical card theory guide please advise.
