Debian squeeze: How to change screen resolution?
 

Hi All,

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

My apologizes in advance if I have landed in the wrong place, but I have been Googling for days. I should mention that I am using a varient of UBUNTU 12.04 LTS (Backbox Linux), with the XFCE DM.

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.

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.
