Hi, I'm having a little problem, and I couldn't find the answer in other post I've read.

I have an Acer Laptop with an ATI Radeon HD 3200 on-board graphic card.

The best resolution for the notebook is 1366x768, since any other looks blured.

The issue:

I have a brand new ASUS N76 with newly installed 12.10. HDMI port is not recognized by Ubuntu while working perfectly well with Windows 8. xrandr does not even show as known connector :

Output of xrandr

Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 8192 x 8192 LVDS1 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 382mm x 215mm 1920x1080 60.0*+ 59.9 4

Whenever I come to work I type

xrandr --auto xrandr --output VGA1 --right-of LVDS1

This gets my second display working, however now I get

xrandr: cannot find crtc for output VGA1

For reference here is the output of xrandr,

[ubuntu] Dual Monitor Woes 41 weeks 6 days ago

Hi,

I'm running into an issue when trying to set up my dual monitors with 12.04. I'm using Unity with Lightdm, and my second monitor (with desired 1920x1080 resolution) is only 640X480! Also, the second monitor is completely white with a black x for a cursor.

Today I was trying to connect my second monitor to my notebook.

I get the following output when I run xrandr:
