It has a NVIDIA Quadro FX 3800M built in. I did a fresh install out of the box on a clean system with Ubuntu 10.04 64-bit. As long as I am using the internal laptops monitor everything is fine and runs very fast and stable. But if I connect an external monitor via the docking stations DVI I receive a blank screen with a non-blinking cursor in the upper left. X does start but it is not visible (starting sound is heard). Also the console windows can be accessed and used. As I have found, forcing xorg.conf to throw an error, for example with a statement anywhere in xorg.conf like "ForceError 1" which is not parsable, X will come up with an error saying something like "Syntax Error", "X running in low resolution", and then asks what I want to do. Please note that now _this_ happens in a graphical display! I answer "run X with low settings for this time", X says "restarting" and then everything is perfect and as fast and stable as with the internal monitor. X does _not_ run in low resolution, it runs perfect just as with the internal monitor - if X has thrown an error during init. Otherwise it is gone. Seems like X does some preliminary initialization if it encounters an error in the xorg.conf which nouveau has missed. But if X has correct config data it assumes all necessary inits have already been made and nouveau displays its screen somewhere in nirvana... X is reported to be running on screen 0 (which would be correct), but the display actually is in nowhere-land. I have searched for many days now but could not find a solution, for example an additional init-command to be placed in xorg.conf. Though I can live with it easily (have to press OK twice when starting, after that no problems at all) this took me a long long time to get Linux installed, and it might arise from some deeper problem not so easily to be circumvented by some other user. So I decided to report this problem. If you need any additional info please let me know. Have a good time, best regards, Michael PS: NVIDIA proprietary drivers don't run at all on my system. They crash (very early in the boot process requiring a reinstall/restore) whether internal or external monitor is used. Using VESA of course isn't really an alternative but this runs without any problems. I didn't try NV yet and don't really want to (since this is a deep system operation hard to clean up and I have found a circumvent working very good). -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug.
