intel 945 gme; intel driver and external displays

ealin · October 16, 2008, 10:39am

Hi,
I try to connect an external display (1440x900) to a laptop (dell inspiron 640m) with intel 945 GME, intel driver and opensuse 11 64 bit.
Up to know I used as a workaround the i810 driver + profiles. (two different xorg.conf files).
Now I decided to try the intel driver.
So I launch Sax2 I configure the display for the right resolution I test it, save it and reboot.
Of course the things do not work by itself decides that 1024x768 is better for him.
Here is the xrandr output

TV disconnected (normal left inverted right x axis y axis)

If I manually set the resolution wit xrandr things seem to be perfect

The xserver is started by kdm4

Any thought about?

there is also an annoying side effect. The display flickers too.

Found a kind of solution

in /etc/sysconfig/displaymanager

look for

Type: string

Default: “1024x768_60 64.11 1024 1080 1184 1344 768 769 772 795 -HSync +Vsync”

Mode to use for laptops for DISPLAYMANAGER_RANDR_MODE_* on laptops only,

when the according variable is set to “auto”.

(RANDR 1.2 compatible drivers only).

and set
DISPLAYMANAGER_RANDR_MODE_auto=""

This seems to cure both the strange resolution + the flicker.
