Description Zsolt Sági 2008-11-07 16:00:25 UTC

Starting from openSUSE 10.3 (if I remember correctly) openSUSEs misdetect the resolution of my Compaq nc6320 notebook. It's 1400x1050, but newer openSUSEs recognize it as a smaller resolution display, so I have to change it manually after the installation. Older openSUSEs and for example the BackTrack3 distribution can correcltly identify it. I don't know what information you need, so I attach my current (SaX2 generated, 1400x1050 resolution) xorg.conf.

And older xorg.conf

I don't think the detection has changed. With older distributions automatic configuration was not available or at least not the default, so you simply adjusted the resolution already during installation.

Please add the output of 'hwinfo --monitor' and also attach /var/log/Xorg.0.log with the initial configuration on 11.1.

Monitor not detected. Resolution according to kernel framebuffer resolution.

Use SaX2 to configure your resolution.

Comment 8 Zsolt Sági 2008-11-20 16:13:45 UTC

I installed openSUSE 11.1-Beta5, and now the resolution is correct (1400x1050). However, I installed it a different way now: at the beginning of the installation, I chose automatic setup instead of manual.

BTW, my driver is Randr capable, so this bug may be different from bug 440973.

In addition to this, I've tested the fn+F7 display changing function, and it worked, with a slight difference: I had to use fn+F4, but this may be normal, since that's the display changing keycombination of my notebook. The only little problem wast that the external VGA display's ratio was 16:9 (not 4:3 like that of the builtin LCD panel), and the image was distorted on the VGA display because I was unable to set different resolutions for the two displays (but I don't consider it a problem).
