Xorg with Intel integrated Graphics: High resolution not default

Hi,

since I upgraded to the latest kernel and graphics (xorg-server{,common}, libdrm, libgl, mesa, intel-dri, xf86-video-intel) the autodetection and configuration of the highest resolution in X stopped working.

I don't use a custom xorg.conf, and until yesterday the resolution after starting X would be automagically 1920x1200 - the highest resolution supported by my monitor which is also what I want.
With the new packages installed I sit at 1024x786. The higher resolutions are still supported and selectable by e.g. xrandr.

Is this a known problem?
I suspect that this is some kernel problem, as I first downgraded all the graphic packages, which did not help. Downgrading the kernel package + reboot helped though.

Kind regards
Julian

Re: Xorg with Intel integrated Graphics: High resolution not default

All I can say is that the resolution is still good here after the update and a reboot. I'm using Xfce (4.6) but I don't think it matters since I think the resolution is set to 1920x1200 before X is launched...

I do have a xorg.conf, but after removing the comments, it looks like:

Section "Screen"
   Identifier   "Screen 1"
EndSection

I've got a Core i3 (DRI driver: i965) and my monitor is plugged via HDMI.

Edit: clarified that everything _works_ here .

Re: Xorg with Intel integrated Graphics: High resolution not default

I have an integrated intel graphics card too and haven't noticed any issue besides some strange warning messages in /var/log/errors.log after I updated today. I also updated the kernel, and had no issues with X and don't use an xorg.conf.

Re: Xorg with Intel integrated Graphics: High resolution not default

I haven't found any warnings or errors in the logs.

Chipset: Intel NM10
Intel Atom D510 with integrated Intel Graphics Media Accelerator 3150.

I now upgraded again and use a xorg.conf, which works as before:

Section "Monitor"
    Identifier      "External VGA"
    Modeline        "1920x1080_60.00"  172.80  1920 2040 2248 2576  1080 1081 1084 1118  -HSync +Vsync
    Option          "PreferredMode" "1920x1080_60.00"
EndSection
Section "Device"
    Identifier      "Intel"
    Driver          "intel"
EndSection
Section "Screen"
    Identifier      "Primary Screen"

    EndSubSection
EndSection

Re: Xorg with Intel integrated Graphics: High resolution not default

Hi there.
I've got the same problem with my D510 computer. I don't use an xorg configuration file.

xrandr shows me two video interfaces : LVDS1 and VGA1. I don't remember seeing LVDS1 on this computer before. The motherboard has one VGA port and no other visible display port.

LVDS1 is the interface with the wrong resolutions :
Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 4096 x 4096
LVDS1 connected (normal left inverted right x axis y axis)
   1280x800       58.1 +
...
VGA1 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 510mm x 287mm
   1920x1080      60.0*+
...

xfce display configuration also reports two screen, one named "portable", french for "laptop", and the other one is my real screen. As i recalled it showed only one screen before this update.
By disabling the first screen the resolution is ok once in xfce.

I've just started my analyse of the problem and I'll come back if I found more informations.
