After paying attention to how my computer boots, I've finally found a consistent relationship. If I boot my computer from battery power alone without AC, my GPU & the Ubuntu splash screen load on startup. However, if I start my laptop on AC power, with or without the battery connected, it seems to be random luck if the GPU does load, and most of the time it doesn't.
Whether peripherals or wireless are active doesn't seem to matter. I've gone ahead and added a kernel-acpi tag because power management seems to be involved somehow. ** Tags added: kernel-acpi -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1009312 Title: GPU loads unreliably, possible kernel timeout To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1009312/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
