I now think that the freeze issue might come from a hardware problem : I made a test that worked well : - I removed the overclocking of my CPU (so that the CPU uses its normal speed). The overclocking was stable for years, but one never knows. My graphic card is not overclocked - I reduced the screen resolution to 1024x768 (instead of 1600x1200) - I used the DVI output instead of the VGA output (with the same flat screen)
This time, the youtube video was stable. The reduced CPU speed made it choppy, but at least the machine did not freeze. That makes me think it could be "simply" related to the overclocking. Why did the freeze not happen when not using the proprietary nvidia driver? Maybe because the open-source driver does not use some hardware acceleration. Maybe in this case the AGP port draws more current or something similar. Why did the freeze happen only after the upgrade to karmic? Maybe a coincidence (even if I would find it surprising). Maybe the recent versions of the nvidia driver and/or the flash plugin make use of a feature that was not used before, and that leads to the problems with overclocking I only can make assumptions, but at least I have a workaround -- Freezes with nvidia-glx-185 or -190 after upgrade from jaunty to karmic https://bugs.launchpad.net/bugs/486837 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
