What resolution are the monitors you are using (both the internal LCD and external monitor)?
The "Virtual 2048 2048" line is not meant to be copied verbatim. It is meant to be the size of your virtual desktop. For instance I have a 1400x1050 LCD on my Thnkpad, and if I connect it to my 1680x1050 external LCD, I need it to be, "Virtual 3080 1050" for both displays to function correctly. Additionally I need to setup modes for each monitor. Look in the xrandr man page for a list of ways to set modes (--mode, --newmode, --rmmode, --addmode, --delmode). --mode can be used to set a mode from the file, while the latter four can be used to set modes dynamically. Additionally your displays may or may not be named LVDS or VGA-0, so please check "xrandr -q" for such info. As for the pattern you observed in the first paragraph (blanking before GDM), I believe that this behavior is because X.org takes over the display responsibilities at that point. If you still can't get it, attach your xorg.conf and the output of xrandr -q and I'll try to help you from there. -- open source ati driver in hardy can't do external monitor on laptop https://bugs.launchpad.net/bugs/222905 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
