I made another experience which could give more clues (I kept the same xorg.conf file and always without battery installed):
1- shutdown, unplugged everything for 1 minute, plugged the AC 2- powered it on, xorg desktop boots fine, glxgears during 30 minutes and other 3D apps without lock 3- safely reboot via KDE 4- xorg desktop boots fine again, run glxgears during 30 minutes and other 3D apps without lock 5- safely shutdown via KDE for 1 minute 6- powered it on, xorg is only a black screen, hear start-up sound 7- pressing the laptop power button to safely shutdown, the laptop shutdown completely by itself 8- let the laptop cool for about 1 hour but WITH AC adaptor still CONNECTED! 9- all laptop seems at the room temperature 10- powered it on, strange, xorg desktop boots fine and run glxgears without lock 11- safely shutdown via KDE for 10 minutes 12- powered it on, xorg is only a black screen, hear start-up sound, seems not freezing With this experience, we could think that there is an overheating problem or some persistence in a chipset memory (AGP, BIOS, video...) that is "cleaned" with time or with complete power down. Maybe I am completely wrong... or maybe not. -- [agp] X.org does not initialize screen on IBM T20, T21, T22 https://bugs.launchpad.net/bugs/33617 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
