For what it's worth I have the same symptoms on a Dell Inspiron 6000 series laptop. It's got an ATI x300 Radeon Mobility, so it's as far as I can tell not limited to Intel graphics. It uses the open-source ATI driver (since when I ask it to look for proprietary drivers it says none is available).
With desktop effects enabled X freezes after about 2-3 minutes. It freezes after about 1 minute if I use it, 2-3 if I just let it idle. Turn off desktop effects and everythings peachy. -- [i945] [i945] (UXA) Intel Corporation 82945G/GZ Integrated Graphics Controller [8086:2772] (rev 02) freezes https://bugs.launchpad.net/bugs/445056 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
