New xorg not detecting resolution correctly

Hi

I updated to the latest xorg:
https://www.archlinux.org/news/xorg-ser … available/

but now it doesn't correctly detect the resolution of my monitor.

Ouptut from xrandr:
$ xrandr
Screen 0: minimum 64 x 64, current 1024 x 768, maximum 16384 x 16384
VGA-0 connected 1024x768+0+0 0mm x 0mm
   1024x768      60.00*+  60.00*
   1600x1200     60.00 
   1440x1050     60.00 
   1280x960      60.00 
   800x600       60.00 
   640x480       60.00 

Previously I did not have to manually configure X. X autodetected the correct resolution.

I am running arch on vbox. I have the guest modules installed and I reinstalled them after updating X.

Re: New xorg not detecting resolution correctly

You reinstalled them?

I take it you didn't install them from the repository then. Do that and see if it helps.

Re: New xorg not detecting resolution correctly

Then I'm not sure why that resolution is selected. I've seen a similar issue with Qemu/KVM, but haven't really done much else than manually specifying the desired resolution.

Re: New xorg not detecting resolution correctly

Ok I think it has something to do with my window manager. I was running xmonad when I posted the output from xrandr above. However if I run gnome I get this:

 $ xrandr
Screen 0: minimum 64 x 64, current 1920 x 1080, maximum 16384 x 16384
VGA-0 connected primary 1920x1080+0+0 0mm x 0mm
   1920x1080     60.00*+
   1600x1200     60.00  
   1440x1050     60.00  
   1280x960      60.00  
   1024x768      60.00  
   800x600       60.00  
   640x480       60.00  

I didn't know that the window manager affected xrandr's output.
