X, Laptop, Mulitple Displays
Hey folks -
I've been beating my head against my desk trying to figure out this X configuration. Hardware: IBM Thinkpad with ATI Mobility FireGL T2. The LCD on the laptop is capable of 1600x1200. I have a monitor that's capable of 2048x1536.
What I'd like to do is have the X server start in 2048x1536 resolution, regardless of whether the monitor's attached. Ideally, this'll make a desktop that's too large for the LCD to display, but it can still scroll around. Using xrandr, I can resize the display back down to 1600x1200 if I don't have a monitor attached. Elsewise, it runs at 2048x1536.
Confused yet? :-) I had this working perfectly on my previous Thinkpad. But this new one's giving me a heck of a time. Using the MonitorLayout option (CRT, LVDS) in the video card section, I'm able to get the server to display 2048x1536 to the monitor. But the LCD is completely disabled. If I reverse the two, then the monitor is 'stuck' at 1600x1200, at 60Hz (bleah!)
I could easily set this up as a dual-head type thing, but that's not what I'm after. I don't want to scroll from one display to the next. The idea here is to use the laptop as a workstation while it's docked (with the LCD closed.) Then when I'm on the go, use it as a laptop.
If you guys have any pointers, ideas, etc, I'd appreciate it. I can include any config files you want to see, but I'll bet by now they're wrong. :-)
