monitor resolution on soni vaio Z suse 12.1

English Hardware
#1

Hi everybody
this is my first post here, and I wonder wether this is the right fprum, ot ‘laptop’ could be more appropriate

I have just got my new sony vaio Z and installed opensuse 12.11

After some work, thanks to all who posted useful infos, I finally have a working system … but for one thing

The resolution of the laptop screen is fixed to 1600x900 and I cannot change it from the system setting panel. Nor I found any other way to change it.
I use the laptop for work, and travel a lot making presentations. Such resolution is totally not compatible with projectors, and I’ obliged
to give presentations disabling the internal screen and … looking at the large screen in the room (which can be very unconfortable, as I
cannot face the audience)

I wonder if there exist a way to downgrade the resolution when I branch a projector, as I did with my (very old) dell laptop with suse 10.2
I should add that I am a total zero in hardware related issues. From the various posts on simlar topics, I just understood to run xrandr, and this is the output of it

Screen 0: minimum 320 x 200, current 3280 x 1050, maximum 8192 x 8192
eDP1 connected 1600x900+1680+0 (normal left inverted right x axis y axis) 291mm x 164mm
1600x900 59.9*+ 40.0
HDMI1 disconnected (normal left inverted right x axis y axis)
DP1 disconnected (normal left inverted right x axis y axis)

Thanks for any help

You xrandr output suggests lower resolutions are not available for your display (which is why no other options will exist via System Settings). However it should be possible to add the required display resolutions as necessary by manually editing a couple of Xorg config files, if you feel comfortable doing that.

Can you provide info about your graphics card and driver?

/usr/sbin/hwinfo --gfxcard

Hi Deano, sorry for my late reply

I am willing to give a try through the Xorg config files. Not much to loose (if I back up everything before…)

Here is the output of hwinfo

deano_ferrari: i too am having the same issue as biancag except mine is a 720p television. 1920x1080 and 720x480 are my only options for this display in system settings. i’d like to use its native resolution at 1280x720. any assistance would be greatly appreciated. here is my /usr/sbin/hwinfo --gfxcard output.

many thanks in advance! :slight_smile:

You might both like to try this approach, using xrandr to add the required undetected display modes. One does have to be careful about generating compatible modelines for the particular display device concerned, but it does allow one to experiment and quickly switch dynamically (without restarting the X-sever)

https://wiki.archlinux.org/index.php/Xrandr

Once you have a working modeline, it can be used to create a minimal xorg.conf to make it persistent, or add the relevant sections to the newer corresponding config files in the /etc/X11/xorg.conf.d/ directory.

thanks deano_ferrari
I had tried something similar, but missing the page you have pointed me at, I had not succeeded in using the correct sintax

I just tried, and it seems to work
THAT’S GREAT!!!

I just have to exactly understand which are the resolution(s) I might be interested in (I must connect a projector for that),
and then it’s done

Thanks a lot for your help
