Linux driver
Use Driver "radeon" in the xorg.conf file - it works at least for xorg 6.8.2, maybe older versions too.
ThinkPad LCD
Display on the internal LCD works as long as you set the monitor settings correct.
External VGA port
There are known problems. The driver from ATI turns off the switching between internal and external port.
Workarounds
- Don't use the ATI driver if you want to use this feature - use the VESA driver instead.
- Start X without an external monitor, and then connect the external monitor. Both displays will be active, and cannot be switched off until you exit X. To have a reasona ble refresh rate on the external monitor (the default is the LCD's 50Hz), use the following in /etc/X11/xorg.conf:
External VGA port
There are known problems. The driver from ATI turns off the switching between internal and external port.
Workarounds:
- Use the "vesa" driver built into X.org instead of the ATI or "radeon" drivers. This loses acceleration and some capabilities.
- Start X without an external monitor, and then connect the external monitor. Both displays will be active, and cannot be switched off until you exit X. Note that if the external monitor is connected when X starts, the LCD will be deactivated and you will need to restart X. To have a reasonable refresh rate on the external monitor (the default is the LCD's 50Hz), use the following in /etc/X11/xorg.conf:
