[Daniele Castrovilli]

Binary package hint: ubiquity

Good Morning,
I have done succesfully an advancing version from ubuntu 9.10 tu ubuntu 10.04.
The problem is the following:
-After the boot up the screen became black and i can't do nothing, but the pc seems "alive" in fact if i press the shutdown button (phisical) Ubuntu go down.

-The same thing happen if i'm capable to log in , and after a few seconds the screen "freezes" and became black.

My PC:

Asus x51R

Video card : Ati x1100 128mb
Ram:2 GB

Ubuntu version: 10.04 Lucid Lynx Beta 1

Thanks

Noone can help me? Is a Graphic card problem?

[Bjorn Ramberg (bjorne-gah)]

There is a similar bug affecting intel graphics. See https://wiki.ubuntu.com/X/KernelModeSetting for disabling KMS, which might help.

[Daniele Castrovilli (danielestrife)]

This will be fixed for the final release?

Hi Cloudany,

Please attach the output of `lspci -vvnn` and `dmesg`, and attach your /var/log/Xorg.0.log (and maybe Xorg.0.log.old) file from after reproducing this issue. If you're using a custom /etc/X11/xorg.conf please attach that as well.

These attachments are from my pc with ubuntu 9.10 and not with 10.04 , i'm not able to do this with LL i'm sorry, the black screen leaves me to do anything.

Hi Cloudany,
Sorry, those files against karmic will be of limited use. Also please attach files as text files not open office documents. That way our automatic bug handling tools can interpret and use them to help get your bug report properly processed and prioritized.

radeontool can be used to assist in debugging this issue. To install it from the command line, use this command:

    sudo apt-get install radeontool

After installing it, you run it like this:

    radeontool regmatch '*' > regdump_good.txt
    radeontool regmatch '*' > regdump_broke.txt

Run it two times. Once when you have a working screen (for any driver), and once in the broken case (either from the tty console or logged into the sick box remotely using ssh or similar). Attach both of those to this bug report along with the other files I requested, and we can then forward this issue upstream. Thanks ahead of time!

[Daniele Castrovilli (danielestrife)]

Ok this is a video of what happens during the installer process

[Bryce Harrington (bryce)]

Thanks for the video, but I need the files I mentioned before we can send this bug report upstream.

[Daniele Castrovilli (danielestrife)]

Ok all of these are from Lucid Yesh i've done it!

[Bryce Harrington (bryce)]

There is a quirk that is applicable to this hardware. I don't know if it would help in your case, but it might be worth testing - the symptoms are an instant freeze after booting up, which sounds similar to what you're seeing. Use the 'pci=nomsi' kernel option and see if that makes the issue resolve. Let us know either way.

[Daniele Castrovilli (danielestrife)]

Ok how i can do this, i'm so newbie in modifing kernel

(google is your friend)

[Bryce Harrington (bryce)]

The symptoms and hardware match up exactly to the msi bug, so I'm going to go ahead and make the assumption that this is in fact a dupe of that. If you find the issue is still present after we get that fix, or if you get the chance to test the nomsi kernel option and find it doesn't fix it, feel free to un-dupe it.

[Daniele Castrovilli (danielestrife)]

Ok i've found , how i can modify my boot option:

-I've modified the file in /etc/default/Grub , at the line i've wrote "pci=nomsi", GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pci=nomsi"

everything gone ok! , the o.s. never crashed, i was able to use Lucid for 2 Hour without screen crashes.

Ok and now , every time i reinstall Lucid must i do all these things? to add everytime "pci=nomsi". or you'll fix this problem with a patch?

Thank You

[Daniele Castrovilli (danielestrife)]

Ok i've tried also the chase douglas's kernel patch , disabling the pci=nomsi option it works perfectly!

I hope this patch will be included in all Lucid's kernels!
