Hi All,

I tweak my H-P Spectre Ultrabook to no end! Recently, I have been playing with screen resolution, or better put, trying to change it.

I should mention that I am using the latest Backbox Linux), with all the updates.

If I run "xrandr" I get:


adler@adler-HP-Spectre-XT-Ultrabook-PC:~$ xrandr
Screen 0: minimum 320 x 200, current 1366 x 768, maximum 8192 x 8192
LVDS1 connected 1366x768+0+0 (normal left inverted right x axis y axis) 309mm x 174mm
1366x768 60.0*+ 40.0
1360x768 59.8 60.0
1024x768 60.0
800x600 60.3 56.2
640x480 59.9
VGA1 disconnected (normal left inverted right x axis y axis)
HDMI1 disconnected (normal left inverted right x axis y axis)
DP1 disconnected (normal left inverted right x axis y axis)
adler@adler-HP-Spectre-XT-Ultrabook-PC:~$



I see that I should be able to take my screen resolution to my desired 1920x1080 level (I think).

When I use cvt, with my desired, screen resolution I do generate a modeline:


adler@adler-HP-Spectre-XT-Ultrabook-PC:~$ cvt 1920 1080 60
# 1920x1080 59.96 Hz (CVT 2.07M9) hsync: 67.16 kHz; pclk: 173.00 MHz
Modeline "1920x1080_60.00" 173.00 1920 2048 2248 2576 1080 1083 1088 1120 -hsync +vsync
adler@adler-HP-Spectre-XT-Ultrabook-PC:~$



I have tried numerous xrandr terminal commands, looked through my xorg.conf file, but see nothing where I can change my screen from the stated resolutions. Nor, can I find where my presently available choices live. Also, I have been Googling like crazy!

My graphics card is:


adler@adler-HP-Spectre-XT-Ultrabook-PC:~$ lspci |grep VGA
00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09)
adler@adler-HP-Spectre-XT-Ultrabook-PC:~$ xrandr



Any help would be appreciated.

Hi,

Personally i don't use command line to set screen resolution for long time. Why? Because we can do that from BBox menu and settings. If you are using BBox from virtual machine (vmware etc..) you need to install vmware tools if you want you resolution to stay same after every reboot.

2nd scenario is after hard disk install, and when standard menu>settings options don't give us solution. We can install xrander and play with settings. And last one is to play with manual settings. That is up to you and your.

Have fun.

Yes, try to follow ZEROF suggestions.
Also, did you look around for some tutorial about specifying custom screen resolutions? Try this or this.
You may need to edit your Xorg.conf, so the best choice is having a look to the manual: man xorg.conf.

Hope you'll solve!
Bye.

ZEROF + b4d_bl0ck,

Thanks for the replies. I am not running BB from a Virtual Machine, have been trying to use Xrandr commands to change my settings, plus have been looking at my xorg.conf file. All without any success.

Concerning my xorg.conf file I don't see any screen resolution settings. BB does show in Settings > Desktop a total of 5 to pick from. They are listed in my first post. Here you can also see xrandr tells me I should be able to have a screen resolution of 8192 x 8192! I would be very, very happy with 1920x1080.

My xorg.conf file looks like this:

From what I have read xorg.conf may not be the file to configure.

I'll keep looking, and thanks again for those replies.

Adler,
did you read the links i posted?
You can see the resolution is specified in the Display SubSection of the Screen section of the xorg.conf.
Please, play around with the manual page of xorg.conf. Or maybe try if there are better drivers for your graphics card.

Have fun!

you can't have the highest and custom resolution when you are using VESA drivers. This is a generic linux driver that makes functioning any of video card in case of major problems and it has limited choices in resolutions. Your video card is NOT configured.

So first thing you should do is to configure your video card by installing the proper drivers. then you will see that it will appear the parameters you are looking for.
