[Bug 683775] Re: Natty Alpha 1, i915 has blank screen after boot
I have 3 distros : 1 Natty and 1 Maverick on my internal disk and 1 Natty on an external Usb disk, all 64 bits. Andy's modification helped to boot both Natty, however with better results for my internal Natty (roughly 50% success for warm boots, and 25% for cold ones) than for my external one (maybe 20% for warm boots, and 10% for cold one). Each Natyy has its own swap. A few days ago, I had to boot Maverick (no problem booting), and this then both Natties refuse to boot (I may have since run up to 20 tries on each one). Internal Natty's kernel : Linux 2.6.38-11-generic USB Natty's kernel : Linux 2.6.38-8-generic Maverik's kernel : Linux 2.6.35-22-generic The situation is getting very frustrating, as my Maverik is not complete : does not run WIfi and has no sound. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/683775 Title: Natty Alpha 1, i915 has blank screen after boot To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/683775/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

The bug seems to me not to have been fixed. It takes me up to 6 to 8 tries before any successfull cold boot. I made the modification suggested by Andy in comment #10. Maybe 1 success for every 8 to 10 tries. I don't know whether it still makes sense to test the kernel linked at in comment #14.

I think this is probably the same bug? After clean install from the iso - 64bit desktop downloaded yesterday, it booted into the Unity desktop which seemed to run very slowly and finally stopped responding. On re- boot, the panels had disappeared, and I couldn't make anything happen. I got the startup sound, and the background with an active mouse cursor, but that was all. The only way I got into it again was to boot in recovery mode, and switch to low definition. Once in, I changed the boot to the gnome desktop and it works just fine. I tried putting a root terminal and Nautilus on the desktop and switching back to Unity. The icons failed to appear, so I couldn't find a way of looking around.

As Tim indicates there is an element of a race to this issue. On my test system and upgraded (Maverick - Natty) system the issue was not reproducible in 20 reboots. I scratch installed from the same Natty image and the issue was instantly reproducible. In testing removing the ureadahead pack seems to render the machine bootable for the next boot. All of this tends to indicate that this is indeed a boot race. It is reminicent of the framebuffer open races we experienced in Maverick.

[Bug 683775] Re: Natty Alpha 1, i915 has blank screen after boot
With 2.6.37-7.19 the display will correctly initialize about 1 in 5 times from a cold boot, and never AFAICT from a warm boot. However, the good news is that it recovers the display 100% of the time after a suspend/resume cycle. I've experimented with unplugging the battery and/or booting with power plugged/unplugged with no discernible effect. -- Natty Alpha 1, i915 has blank screen after boot https://bugs.launchpad.net/bugs/683775 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
