Lenovo X201 external monitor resolution issue

Hi,

I'm having issues connecting my Lenovo X201 through the docking station -> display port -> Dell 3011.  The native resolution for the monitor is 2560x1600.  However, I currently can only set the resolution to 1920x1080 (ugly!) as any high resolution results in the monitor entering power save mode.

I'm using xrandr to set the video mode in my .xinitrc (running dwm).  This creates a good Xinerama config for dwm.

I'm currently using the line

xrandr --output DP1 --mode 1920x1080 --above LVDS1

to set my resolution.  When I change to --auto or --mode 2560x1600, or 1920x1200 etc I get the blank screen on the external monitor.  I'm using the xf86-video-intel-sna driver package (I tried the -uxa as well to no avail).

Any hints?

Re: Lenovo X201 external monitor resolution issue

does your video card support resolutions greater than 1920x1080??

lspci | grep VGA

Yes, it will do the 2560x1600 + laptop monitor in Windows 7 just fine.

Re: Lenovo X201 external monitor resolution issue

I was able to get it by having arandr help generate the config, here's the solution that worked for me:

xrandr --output HDMI1 --off --output LVDS1 --auto --right-of DP1 --output DP1 --pos 0x0 --rotate normal --auto --output VGA1 --off
