Debian Wheezy install on D525MW

No problems with installation but cannot set video mode to native resolution of my monitor (1680X1050).

It's unclear why there are 2 devices listed – LAPTOP & MONITOR but the maximum settings are only 1280X800 or 1024X768 respectively. Both are devices are set ON to use?

I know the GMA3150 video chip on the D525MW can display 1680X1050 resolution because it does so under win XP.

Is there a synaptic package/driver that needs to loaded or what?

Thanks.

Hi

What video modes does the output of xrandr list?
(xrandr > xrandr.txt and attach the xrandr.txt produced)

You may need to install it, can't remember if in base install.

Xrandr reports:

Screen 0: minimum 320 x 200, current 1024 x 768, maximum 4096 x 4096
LVDS1 connected 1024x768+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
1280x800 58.1 +
1024x768 60.0*
800x600 60.3 56.2
640x480 59.9
VGA1 connected 1024x768+0+0 (normal left inverted right x axis y axis) 0mm x 0mm

800x600 60.3 56.2
848x480 60.0
640x480 59.9

I'm using the VGA output.

The following video related packages are installed:

libxrandr-dev
libxrandr2
x11=xserver-utils

i965-va-driver
libva-x11-1
libva1
xserver-xorg-video-740
xserver-xorg-video-intel

It looks like the driver can do more resolution (4096 x 4096) but the listed modes top out at 1024 x 768?

Thanks

I have a D525 working with Wheezy as a media server connected to my TV.

It can do 1980x1080 (ie full HDMI-ish) using the on board chip, but I had to set the modes.

Google using cvt and xrandr.

cvt will get you a modeline string for your desired resolution and monitor frequency
www.x.org/archive/X11R7.5/doc/man/man1/cvt.1.html

eg cvt 1680 1050 60

You can then set that mode and select it using xrandr

This gives a tutorial

There are plenty more

OK, that sure got me on the right path. I was able to use that information to set my mode. Most of the info about keeping the setting persistent does not seem applicable to the Xfce desktop.

Searching around turned up mostly confusion on how to do it with Xfce early in the boot process. I finally just added a script to session start-up as a workaround.

Many thanks …
