X61s with Slackware - Multiple Monitor with Dock

[techflavor]

Hey all --

I just received my x301 so I'm now converting my x61s (with dock) into a completely Slackware based linux machine (being used for IT security, penetration/vulnerability testing, monitoring, etc.)

I would like to use my x61s LCD as the primary monitor with an external monitor with an extended desktop (not mirrored).

I have everything working just fine; however, I'm having some minor issues with multiple monitor support in Slackware.

I'm almost positive I have xorg.conf configured correctly as I got it from another guy who is running Slackware on his x61s (with multi monitor support). You may find his blog post on the installation at: http://dotdideriksen.blogspot.com/2008/ ... -x61s.html I have also left two comments on his post but will also be posting them here in hopes for some additional help.

Whenever I startx with the external monitor plugged into the dock, both monitors come on with the display mirrored. The external monitor is setup to its correct resolution (1280x1024); however, the x61s LCD is not being set to its 1024x768 (it looks like it is being set at a much higher reso.. probably 1280x1024). If I startx without the external monitor plugged in, the LCD comes up with the correct resolution (1024x768). When I run xrandr it shows the VGA is connected at 1280x1024 and LVDS is connected at 1024x768.

So I then tried it a little different. I unplugged the external monitor, performed startx, the laptop LCD came up with its proper resolution. I then plugged in the external monitor to VGA and did a manual xrandr command to see if it would send the display to the external:

Code: Select all

xrandr --output VGA-0 --mode 1280x1024 --left-of LVDS

It did not work... it didn't complain about the command (only if I did --output VGA would it complain.. it only liked VGA-0). However, xrandr still showed that VGA was connected.

You can find a copy of the xorg.conf and other specifics I'm using by navigating to the above URL mentioned.

I would really appreciate any input.

Thanks in advanced.

EDIT -- and it would be nice if anyone was running Slackware 12 and had a good copy of xorg.conf configured for multi-monitor support to upload to the forum for others to use
