(solved) Wrong Screen Resolution

Hello,

Yesterday evening I installed opensuse 10.3 on my laptop (ASUS M3N). It detected my intel 855GM graphics card and I configured it with a resolution of 1400x1050. No problems, everything worked fine.

This morning I changed my monitor from "LCD1400x1050@60HZ" to "LCD1400x1050@70HZ". Don't ask me why, I regret I did it. Since then my monitor is stuck at a resolution of 1368x768. No matter what resolution I choose, it doesn't change.

I tried changing my monitor back, selecting an LCD monitor with a lower resolution and setting it to 800x600. Nothing helps, it is completely stuck at 1368x768. I also removed the modlines for this resolution from my xorg.conf, no effect.

At the moment I'm considering a new clean install of opensuse, because I know it will work then. But this will cost me another few hours. Is there any solution to this problem?

Thanks in advance!

manually edit xorg.conf

xorg.conf I think may be located at

/etc/X11/xorg.conf

and there will be a Screen resolution line with a number of resolutionss to choose from. The first one in the list (all on one line) is the default and the rest will be options you can choose from.

You may have to log in as root to open/change/save the file.

Also, maybe try reducing the refresh rate (70Mhz -> 60MHz). It may not like the refresh rate and so drops to the first on the list (in xorg.conf) that it can happily run.

Hi,

Thanks for the response. I spent several hours trying to edit xorg.conf, without any success. The error in in Xorg.0.log was that "vrefresh out of range". Changing refresh rates didn't work either (have to admit I'm no expert on doing these things). Only result was a resolution of 1152x768 or something like that.

Finally I decided to do a new clean install, because I hadn't done any configuring yet. Took me two more hours, but now everything is back to normal: 1400x1050. Also made a backup of my xorg.conf this time

But thanks again for the suggestions!

Too bad you didn't also backup the bad xorg.conf to compare and see what, if anything, changed.
